Several readers have asked lately about the impact of fruit–specifically the sugar in fruit–and it’s capacity to cause weight gain and accelerate aging through insulin signaling:

“Do people usually gain weight because of eating fruit and does the sugar in fruit age us?  I just hate to think that I am doing my body harm by eating fruit.”

If this question sounds insane to you, it shouldn’t. It is actually a very reasonable query that was sparked by two Summer Tomato articles, one about saving money while eating healthy and another on calorie restriction, aging and quality of life. In the first article I recommend thinking of fruit as dessert, a treat to be enjoyed once or twice per day. The second article is about the impact of sugar and calories on aging.

Body Weight

The fact is that fruit contains a lot more sugar than other natural foods and in large enough quantities it can contribute to weight gain. But fruit is certainly not bad for you, nor is it worse for your health than anything else in life.

The sugar in fruit contributes calories to your diet, but since you need calories to survive fruit is still a very good choice. The reason is that in addition to sugar (fructose, to be specific) fruit also has vitamins, minerals, antioxidants, fiber and many other things that contribute to health and possibly slow aging.

On the rare occasions when I do make an effort to lose a little weight, however, remembering that fruit should be dessert is something I keep in the back of my mind. I eat fruit every day, but when trying to lose weight I keep it under two servings and always choose whole fruit–avoiding anything blended or juiced. (Drinking calories is usually a bad idea.)

But this healthstyle tactic is not for everyone.

Why?

Unlike most people trying to lose weight, I already have a very healthy diet and fruit is one of the easiest places I can trim calories without feeling deprived. Cutting out things like fat and protein make dieting very difficult because you are always hungry. In my experience reducing unnecessary carbohydrates–especially sugars–is the easiest and healthiest way to lose weight.

But it is essential to remember most people are not overweight because they eat too much fruit and the vast majority of people would benefit from eating more of it.

Aging

The question about whether sugar causes aging is a fascinating one that I am very interested in.

Yes, in most organisms eating sugar has been shown to promote aging, but this has not been proven in humans. Sugar induces aging via the insulin signaling pathway, so therefore any food that increases insulin signaling could theoretically accelerate aging. The problem is that you need insulin to survive–those who cannot produce insulin have a disease called type 1 diabetes.

The good news is that eating a diet that minimizes insulin signaling is also the best way to lose weight and stay healthy, so if you are living a healthy lifestyle (one that includes fruit) you do not need to worry about anything else.

Although fruits have sugar, it is extremely unlikely that they accelerate aging. In fact, most evidence suggests that fruit slows aging because of its high levels of vitamins, minerals and antioxidants.

If anti-aging is your goal, fruit is your friend not your enemy.

Conclusion

While fruits contain sugar, they do not pose a special threat to your health goals. Eat and enjoy fruits as a wonderful and delicious part of life.

How much fruit do you eat?

Quarter Pounder

Last week in For The Love of Food I called out Men’s Health as B.S. of the Week for their article, “Eat healthy at the airport.” There seems to be a growing trend in the number of weight loss programs that support eating fast food. The idea is that some menu items have slightly fewer calories than others and do not contribute (as much?) to weight gain.

It is true you can lose weight eating anything (so long as you do not eat very much of it), but that does not make eating fast food a good idea. What is misleading about these programs is the grossly inappropriate use of the word “healthy.”

Credit the book Eat This, Not That for this special brand of quackery on which Men’s Health bases their article. They begin with the example of McDonald’s (because, you know, where else are you supposed to go eat?) and suggest you order the Quarter Pounder without cheese (and without fries and soda) over the Premium Grilled Chicken Club.

The reason?

The Quarter Pounder has only 410 calories compared to the 570 calories of the chicken sandwich, a 30% reduction.

To me this sounds the same as saying 7 cigarettes is healthier than 10 cigarettes.

Sure it might be “better” to smoke a little less, but do you really believe you are doing yourself any favors? You’re still ingesting something toxic. Would you be happy if China promised to put a little less melamine in your child’s baby formula?

After decades of consuming slightly smaller doses of poison is it logical to think you’d be a more sprightly 80 year old than you would have been eating full dose poison? I don’t think so.

Rationalizing

Rationalization is the name of the game here:

“Some people are going to eat fast food no matter what, it might as well have fewer calories.”

“It’s impractical to not eat fast food. What if I’m in a hurry?”

“There’s nothing else to eat at the airport, do you want me to starve?”

“I cannot afford to eat anything healthier. Value meals are the best!”

“I just eat crap then spend extra time in the gym, so it balances out.”

“I love junk food and could never stop eating at McDonald’s.”

*shiver*

The problem with all these faux arguments is that they are based on the assumption that fast food is an inevitable part of life, too powerful to resist or avoid. My guess is we can thank the McDonald’s marketing team for this twisted bit of psychology, but that does not mean we have to accept it.

Here is why those arguments don’t hold water:

• The “fact” that some people will continue to eat fast food does not preclude the need to have a diet that endorses it.

• There is always something to eat besides fast food. In fact, there was actually a time when Burger King didn’t exist!

• A few healthy-ish options can be found at the airport, but if you do a tiny bit of planning beforehand you don’t have to be stuck eating there in the first place. Another thing to consider is that starving would be healthier, since caloric restriction has been consistently shown to improve health, prevent disease and extend life. (But don’t worry, going hungry isn’t necessary.)

• The organic kale and tempeh I ate for dinner last night cost the same (~$3.50) as that flaccid Quarter Pounder in the photo, and smelled 1000% better (yeah, I actually bought one). [For the record: I did ask for it without cheese and they just botched my order--can you imagine it looking even more tasteless? Blah. So much for tricking yourself into eating fewer calories.]

• Working out is very important for your health, but it does not give you essential vitamins, minerals and all the other wonderful things offered by whole foods–exercise cannot substitute for a healthy diet.

• There is room in your healthstyle for any food on special occasions. Personally I prefer to use my occasions for exquisite (rather than cheap) meals, but for some of you special may mean going out with the guys for game night or a road trip from L.A. to S.F. (i.e. the In-N-Out in Kettleman City). What is important is that you make sure foods that do not contribute (or are detrimental) to your health make up an extremely small proportion of your diet.

The Real Problem

I contend that the real issue is not that there is nothing else to eat besides fast food, but that we are not trained to recognize any other option. There is a whole world of food out there that does not include unsanitary chain restaurants.

The little secret those of us who don’t eat fast food know is that this other world is far tastier than the one of processed foods and chain restaurants. Also, the convenience factor is easily overcome if you approach it right.

The Answers

Your first defense against eating foods you didn’t plan for (isn’t that what fast food really is?) is to make sure you have a plan. Always.

Rule #1 is to know what, when and where you are going to eat all your meals throughout the day by the time you leave your house in the morning. Not doing this is setting yourself up for an uh-oh. If you are not able to know for certain the specifics of your meal plans, at least try to envision the most likely scenarios and think of ways to make them as healthy as possible. Trust me, these decisions are a lot easier if you make them before you are starving and willing to eat a deep-fried shoe.

Rule #2 is to always have a back up plan. Is there any chance that your friend will bail on you for dinner? Or that you will get stuck at work so long your neighborhood grocery will close? In cases like this it is best to have a plan B. I keep stuff in my freezer and pantry that can be whipped up at any given moment. I also store food in my desk at work for emergencies.

My go-to back up plan is carrying a small bag of nuts like almonds or cashews around with me where ever I go. That way I have something to snack on until I can get myself into a more favorable eating environment. Keep a small bag of nuts in your purse, glove compartment of your car, gym bag, desk drawer or carry on luggage. Your hidden snack should be in whatever container you will be sure to have with you at all times.

Nuts make a particularly good snack because their high fat and protein content (the super good-for-you kinds) make them very satisfying. One day when you are not starving try eating exactly 8 almonds, take a sip of water and wait half an hour. For me, this usually staves off hunger for at least another 45-60 minutes, and sometimes up to 2 hours.

It is more difficult to restrict your intake to 8 or 10 nuts when you are starving, however. But it is easier to exercise self-control if you believe (through experience) that a certain quantity is sufficient to satisfy your appetite. This is why I recommend you try this once before you find yourself in an emergency situation.

If for some reason you end up hungry and do not have your handy bag of nuts, you still have non-Whopper options:

• Grocery stores Most grocery stores have fresh sections with cut up vegetables, fruits, hummus, lean meats and lots of other healthy items (nuts included). Pretend like you are having a picnic and nibble on a few of these things instead or resorting to the drive-thru. You will get plenty of calories, I promise.
• Delis A small sandwich with lean meats and vegetables is a pretty good, easy option if you can find a deli. I would not call this an ideal meal, but it’s better than a BigMac for sure.
• Non-chain restaurants If I am resigned to eating in a restaurant I haven’t planned on the first thing I look for is a non-chain restaurant, preferably a place that specializes in soups, salads and sandwiches. These places are usually well stocked in vegetables and often boast organic produce. They can be a little pricier than a Happy Meal, but it is worth it if you don’t have to eat a gray colored mystery meat patty, right?
• Colorful plates Wherever I decide to dine, I search the menu for dishes that sound like they have a high percentage of vegetables, preferably multicolored. Ordering a side salad or vegetables instead of potatoes is an easy way to accomplish this mission.
• Little bread Giant servings of generic, processed breads made of refined white flour are the biggest problem at most mediocre restaurants. If you can, try to order something that doesn’t require too much bread. This is especially true if you will be sitting on an airplane for the next several hours.
• Avoid cheese Cheese is delicious and I love to eat it occasionally. However, it is common these days for restaurants to bury plates in cheese to mask the crappy ingredients they used for the rest of the dish. Chili’s low quality cheese is hardly worth the extra few hundred calories being used to cover up the fattening, mediocre food you ordered.
• No sweets Sugar is one of the most dangerous things you can eat and should always be consumed with caution. We all love desserts, but you will be much better off saving your sweet tooth for truly special occasions. Airport terminals really aren’t that special.
• Healthy fats I go out of my way to find healthy fats like nuts, fish and salad oils when I am eating solely to satisfy my hunger. These fats will make sure you stay full as long as possible.
• Lean proteins As far as satisfaction goes, what is true for fats is true for proteins. Because they digest so slowly proteins help you feel full longer. Fish, eggs, nuts, beans and even whole grains like brown rice can give your meal a more satisfying impact.
• Eat simply When you are eating on-the-go and in restaurants you are unsure about, your best bet is to stick to simple items. Avoid menu descriptors like glazed, gooey, cheesy, creamy, fiesta, piled, smothered, etc. Sauces are really a problem at airport-style restaurants. Stick to predictable items to keep yourself out of trouble. A turkey sandwich or chop salad are usually pretty safe.

The basic message is to find fresh foods and eat as balanced as possible. No matter what you order this is probably not going to be the most delicious meal of your life, so you may as well try to make it as healthy as possible. A little planning–like eating before heading to the airport–can go a long way in saving special occasions for food that is truly special.

Never trust anyone who doesn’t believe that dessert is an essential part of life.

There may be some small, joyless percentage of the population who can live indefinitely without sugar, but in my experience those who attempt it are kidding themselves and will inevitably fail.

Sugar is wonderful sometimes, and in general it is easier to find a way to live with it than without it.

But I’m not here to propagate any illusions either. The scientific literature makes it is pretty clear that all sugars, specifically sucrose (table sugar) and fructose (the sweet stuff in fruit and corn syrup), are the worst foods you can eat and should generally be considered toxic.

Sugars promote aging, weight gain and most chronic diseases. Sugar is also regarded as addictive by many in the field of obesity and weight loss.

So how should you deal with it?

Keeping desserts in perspective goes a long way to helping you make smart choices.

Keep these tips in mind to make sure the desserts you choose are worth it.

6 Tips To Optimize Your Dessert Choices

1. Make it formal

Self-control is not the easiest thing to practice when dessert is involved. You probably know this from experience.

Make a rule for yourself to not eat dessert in an informal setting. That is, do not eat sweets between meals and always sit down and be fully present when you eat treats.

Resist the piles of cookies, brownies and candies set out around the house. If you do choose to eat one, do not make light of it. Sit down with a chair, table and napkin and enjoy every bite.

Try to wait until after a meal so you are eating for indulgence and not to satisfy your hunger–trying to feel full from dessert is a losing battle (see tip #4).

2. Size matters

Dessert has an obscene amount of calories. I know this is not fun to think about, but you should be aware that if you are eating something with sugar and fat there is an excellent chance you are putting down 50-100 calories PER BITE.

A single Godiva or See’s truffle runs at about 100 calories. A slice of Oreo cheesecake from The Cheesecake Factory has 600-800 calories. It is hard to overemphasize how huge this really is. If you eat a reasonably healthy diet, this is likely more calories than you consume in an entire meal.

When you do sit down and eat dessert, remember that you do not have to eat everything that is put in front of you. The first two bites are always the most satisfying. There is no need to test the hypothesis that the 12th bite doesn’t live up to them.

3. Make an allowance

You should keep tabs on how often you eat dessert, and 1 or 2 per week is a reasonable goal for someone looking to maintain their weight. Zero to one serving is best for someone trying to lose weight.

For most people, weekly allowances are easier to manage than daily or monthly allowances.

Rules likes this help you make smarter choices. Do you really want to waste your only treat this week on a cookie from a box or a cake from Costco?

If you are ever going to be a picky eater, dessert is the best place to turn up your nose.

4. Don’t treat yourself when hungry

Sugar does not satisfy hunger. In fact, repeated sugar exposure creates spikes and dips in blood sugar that make you feel hungry again sooner than you should.

For this reason, sugary foods should never be substituted for real food and you should not rely on them to satisfy your hunger. Not only is this ineffective, it also makes it more likely you will overeat. Remember tips #1 and #2 and eat your small desserts after a real meal.

5. Eat healthy meals

Having an overall healthy, balanced diet is another effective way to avoid dessert binges. If you already feel satisfied with what you have eaten, dessert will truly be a treat and not an overcompensation for poor nutrition.

Healthy meals can also go far to prevent emotional eating, since they help create a feeling of fulfillment, comfort and satisfaction.

6. Stay on the bandwagon

Slip-ups happen with dessert, and it is not the end of the world.

Remember point #2, that size matters.

Just as 5 bites of dessert is much, much better than 10 bites of dessert, one slip-up is better than 3-4 slip-ups. Don’t let one holiday uh-oh send you into a week of unbridled gluttony.

When it comes to sugar, less is always better. Avoid the temptation to throw in the towel.

Are your desserts worth it?

Abandoning the idea of “going on a diet” is one of the most difficult and important adjustments to make when you are trying to lose weight and improve your health. But to achieve and maintain your fitness goals, learning to think in the long-term instead of the short-term is a necessity.

We’ve been conditioned to think about our health as a temporary endeavor. When we find ourselves getting a bit out of shape we assume we need to start a new diet plan and maybe join a gym or cardio class.

“But, you know, things are busy right now and I’ll get to it in a couple weeks when I have more time.”

Even if we do start the plan and lose some weight, how long will it be before we slip back into our old routine and the pounds creep back on?

If you learn only one thing from Summer Tomato I hope it’s that diets don’t work. Calorie restriction in any form can induce temporary weight loss, but the vast majority of people emerge worse off than before they subjected themselves to the difficult and demoralizing task of losing weight and inevitably gaining it (plus a little extra) back.

The science is painfully clear that only long-term and consistent healthy lifestyle choices result in permanent weight loss and improved health.

To really win this war you need to shift your focus from short-term diets and weight loss goals to lifelong habits that promote good nutrition and a healthy metabolism–changes that, in my opinion, should be welcome and enjoyable.

It is never too late (or too early) to get started on your upgrade.

But once you’ve made the commitment to a better healthstyle, how do you know you are making progress without the specific goals and endpoints you get from a temporary diet plan?

This is an excellent question and something worth taking a minute to think about. The answer will be different for everyone and depend substantially on where you start and how you define success.

An example of a fantastic healthstyle goal would be getting off cholesterol, blood pressure or diabetes medication, something attainable by the majority of people taking them. For others the goal may be avoiding meds in the first place by reaching a healthy body mass index (BMI). Health goals like these are obviously a first priority for anyone facing them.

But healthstyle is not just for people with serious health problems. After all, the “normal” BMI range is pretty lenient and you may still have the goal of fitting back into a certain pant size or reaching a specific body fat percentage. These are certainly reasonable goals, especially when you are not approaching them from an all-or-none, feast or famine mentality.

But in my experience, specific number-oriented goals have little stay power when health is your top priority.

When you focus on eating delicious, healthy foods and getting regular exercise (in any form), as the months and years pass goals like reaching a certain body weight or jeans size start to feel a bit contrived. This isn’t because physical appearance or achievements aren’t important, but as your metabolism changes and your body gets healthier it becomes clear that you can feel and look a lot better than you ever really imagined.

What exactly defines the perfect weight or size anyway?

I am not trying to trivialize specific fitness goals nor the effort required to attain them. If you’ve read my diet history you know that I am not immune to aspirations like these. But over time feeling good becomes a more meaningful and satisfying goal than fitting into your jeans. And in my experience, the more energy I put into being healthy and living well, the smaller my jeans get anyway.

For awhile now my healthstyle goals have had little to do with body weight. Instead I choose to focus on habits I can develop that will improve my life and health overall. These include cultivating my cooking skills, learning to eat mindfully and figuring out the best lunch for an awesome afternoon workout.

Here are some of my recent healthstyle goals, which are changing constantly. Please share yours in the comments below.

In a nation where obesity and health loom large in our public dialog, there is no escaping the simple fact that we eat too much.

On average Americans consume 500 more calories per day than we did in 1970 (more than we ever have), mostly in the form of refined and processed foods. This corresponds with a 25-30 pound increase in body weight and obesity rates near 30%.

Debates rage over the specifics of what is causing our weight and health problems, but it seems clear enough that the critical element is the amount of food we choose to put in our mouths.

But does everything we eat represent a true choice?

In his book The End of Overeating, former FDA commissioner Dr. David Kessler examines the role of the brain in eating behavior and the mechanisms involved in what he calls conditioned hypereating.

According to his findings specific combinations of sugar, fat and salt hijack the reward pathways of our brain and force us to behave more like food addicts than hungry organisms. This leads to a cycle of conditioned hypereating that makes the habit harder to break with each repeated episode.

But whether or not we are addicted to food is a point of debate. In my interview with Kessler, he made clear he does not use the word addiction for fear of oversimplifying conditioned hypereating. Our relationship with food is more complicated than it is with something like alcohol or tobacco because a human can live without cigarettes, but food is vital to survival.

When pressed to describe the neural differences between addiction and conditioned hypereating, however, Kessler conceded, “The fundamental circuits are the same.”

For this reason, treatment of conditioned hypereating can draw from the success of substance abuse treatments. These tactics involve cognitive and behavioral therapies we can use to train ourselves to override our instincts and adopt new behaviors in response to stimulus cues.

For conditioned and compulsive behavior, cognitive strategies are necessary because intuitive inclinations and “listening to your body” do more harm than good. If your body is telling you to have a cigarette, this does not mean it is in your best interest to do so.

At the FDA Kessler was instrumental in the fight to regulate tobacco, and now he believes some of the same lessons can be applied to the treatment of overeating.

“What took me a decade to understand is you need to change the valence of the stimulus.”

The positive emotional reaction associated with indulgent foods is at the center of our motivation to seek them out. Twenty years ago cigarettes had tremendous allure. But the FDA was successful at demonizing the tobacco industry, and the public no longer sees smoking as glamorous and attractive.

And smoking rates have plummeted.

Changing a conditioned behavior requires a fundamental shift in how we think about a stimulus. In conditioned hypereating the stimulus is food, which makes the task especially difficult, but not impossible.

To break the cycle of conditioned hypereating we must redirect our automatic response to the kinds of foods that cause us to overeat. Kessler calls these hyperpalatable foods, which are loaded with layers upon layers of sugar, fat and salt. The goal is to replace our automatic responses to these foods with different, equally enjoyable actions that are not detrimental to our health and do not reinforce compulsive behavior.

I asked Kessler what is the first step in controlling our eating habits and overcoming conditioned hypereating.

“I can tell you the last step. Change your relationship with food. If sugar, fat and salt are your friends, you will lose. You have to get to the point where that is not what you want.”

The End of Overeating outlines the four basic steps of habit reversal: awareness, competing actions, competing thoughts and support.

But Kessler believes the critical step is fundamentally changing the way we view what we eat, cooling down our emotional response to hyperpalatable foods. In essence, we must train ourselves to stop wanting what we believe we want.

According to the book, the first step in this transformation is becoming aware of the power food holds over us, which requires understanding how our brains work. We must recognize that when we are tempted to indulge, the urge is not generated internally but is a reaction to a cue that makes us respond automatically. You may think you are hungry, but really you are just reacting to an emotionally charged stimulus that tells you to eat.

Once you recognize a cue for what it is you have a brief moment to decide not to take the bait. To successfully divert yourself to another course of action you must have a plan ready in advance that allows you to do something completely different.

Considering alternative activities and the reasons you might prefer them can help you tremendously at this point of decision. Rather than focusing on the positive emotions you will experience by giving in to your desire for hyperpalatable foods, also remember the negative emotions that follow if you give in and the positive aspects of the alternative action.

For instance, it may help to remember that every time you get cued and give in, you are strengthening the neural circuitry that compels you to this behavior in the first place. If you even briefly entertain the possibility of indulging, you create a state of ambivalence that leads to torment, obsession and cravings. However, when you successfully divert your attention to another rewarding activity you have made a small step toward cooling down the positive valence of the food.

It is the state of mental torment and ambivalence that increases the positive emotional charge of a food, building and strengthening the neural reward circuitry that causes conditioned overeating. This may be one of the reasons dieting almost always results in long-term weight gain, since constant deprivation makes hyperpalatable foods more difficult to resist and creates severe anxiety.

Mentally, the best strategy to overcome conditioned hypereating is to develop new, positive associations with food that are independent of palatability–something you care more about than the fleeting reward of overeating. Kessler says this is a deeply personal process and must reflect an individual’s own set of values. For example, it helps some people to become vegetarian, while others value organics or local food. These decisions remove virtually all hyperpalatable food from the lives of people who choose these paths.

It also helps to develop aversions to hyperpalatable foods. Some may learn to demonize “Big Food,” while others turn away after educating themselves about health concerns. Developing a more sophisticated culinary palate can help make hyperpalatable foods less palatable. Kessler himself developed an aversion to over-sized portions, which he now sees as repulsive piles of sugar, fat and salt.

Developing positive associations with healthier foods while demonizing the hyperpalatable foods we have been conditioned to crave can fundamentally change your emotional response to stimulus cues. As you learn to recognize your brain’s response to cues, you can override conditioned behavior by consciously deciding to take alternative actions because you want to.

You will never win an internal battle with yourself. Instead use what you know about the brain’s reward system and give up trying to summon willpower to resolve the torment of conflicting desires. Reprogram your habits by closely examining your relationship with hyperpalatable food and begin making deliberate decisions that are consistent with your goals, breaking the cycle of conditioned overeating.
