Weight loss is tricky business. Obviously what you eat has a huge impact on your health and body weight. But anyone who has ever tried to modify their diet for the sake of losing weight knows it isn’t so simple.

Most of us understand intuitively that broccoli is healthier than cookies. We can talk about sugar, fat, gluten and antioxidants all day, but that doesn’t change the fact that cookies taste good and you still want to eat them. Any weight loss plan that simply tells you what to eat and neglects why you make the choices you make is unlikely to help you in the long run.

Nutrition knowledge is important, but it is only one piece of the puzzle. The real secret is understanding your behaviors and motivations at their roots, and using this information to have a meaningful impact on your health. In this sense, good health starts in your brain, not on your plate.

The first thing you need to understand is that we don’t have as much control over our food decisions as most of us assume. We tend to believe that we can call on willpower anytime we wish and use it to order a salad instead of a burger, and if we fail to do so it is our own fault. However, self-control is not something we can simply turn on or off, and as a result the process of decision making––particularly when it comes to food––is much more complex.

Approximately 20 percent of the calories we expend daily are used by our brains. Because brain activity is so costly, things like self-control and decision making cannot be relied on indefinitely. As a result, willpower is a limited resource.

Like a muscle, willpower becomes fatigued when exercised too frequently. All the decisions you make throughout the day deplete your willpower, and when you start running out of steam your ability to choose healthy food over more convenient food rapidly diminishes.

Ironically, increasing your blood sugar can help restore willpower to some extent. But finding a healthy way to raise blood sugar in a state of depleted willpower can pose quite the dilemma. Tired brains find it much easier to just grab a cookie.

The way our brains cope with the willpower conundrum is to automate as much of our decision making as possible. It does this by creating habits. Habits are specific behaviors that occur in response to a trigger or cue. They are also always associated with some kind of reward, which in turn reinforces and strengthens the trigger.

For example, a buzz in your pocket is a cue to reach down, grab your phone, pull it out and glance at the screen. The information you see causes a bit of dopamine to be released in the reward center of your brain. We humans love novelty, which is why most of us have a reflexive response to checking our mobile devices when we receive a notification. This is how habits are born.

Once established, habits occur automatically without expending any willpower or mental effort. Scientists have estimated that up to 90 percent of our daily food decisions occur as a result of habits. This saves our brain energy for more difficult decisions where habits cannot be used.

How can this knowledge help us lose weight?

For one thing, it shows that willpower is not particularly reliable as a means to achieve lasting weight loss, and we’re better off spending our efforts creating healthy habits.

It also teaches us that any habit we wish to develop needs to impart a meaningful reward in order for it to stick. You can probably guess that some vague promise of future thinness is not sufficient––the reward for any habit needs to be immediate and tangible.

This means that in order to achieve long-term weight control you need to find healthy foods you actually enjoy eating, physical activities you like doing, and spend your time making these as convenient and accessible as possible.

Fabulous news, right?

Using willpower for restrictive dieting is difficult and incredibly unpleasant. We can all let out a collective sigh of relief that it doesn’t actually work. To achieve true success in health and weight loss, we’re better off quitting diets altogether and focusing on building healthy habits we enjoy.

Try starting with something as simple as breakfast. Warm muesli with a splash of almond milk and cinnamon only takes two minutes to prepare and is absolutely delicious. Invest in a pedometer and challenge yourself to reach 10,000 steps a day. Setting and achieving an attainable goal is a very powerful reward, and is one of the reasons so many people love videogames.

Since our brains are easily overwhelmed, don’t try to develop too many habits at once. Work on just two or three habits at a time, and build from there. Habits take anywhere from two weeks to six months to take root, but on average about two months. Start with the easiest ones and work your way up. Once you’ve built enough good habits, your health will take care of itself.

“I eat way too much sugar and have constant cravings for it that make me feel like I am addicted … do you have any suggestions for cutting back?”

There is still a debate over whether or not sugar is an addictive substance. From the data I’ve seen and people I’ve talked to, I’d guess it probably is.

But whatever the answer, the important question for most of us is how to kill the cravings that have us eating so much sugar in the first place.

Cravings exist in both the body and the mind, and you will have the best luck overcoming them if you address both simultaneously.

The first step is good nutrition. A nourished body is a happy body, and permanently kicking a sugar habit requires healthy food.

Eating balanced, delicious meals is essential for getting real satisfaction from what you eat and leaving cravings behind. For most people this means approximately 50% of your meal being vegetables and the rest split between protein, intact grains and/or legumes (beans or lentils) and a bit of oil or other fat. However, everyone is a little different and you should experiment to find what works best for you.

Healthy eating will not squelch cravings overnight, but it is essential for permanently cutting sugar because it ensures your body has everything it needs. Once your muscles and organs are taken care of, you can address the cravings in your brain.

The first step in breaking a sugar addiction is making the decision to stop eating it completely for at least 4-7 days (the longer the better), and sticking to it. While I usually recommend making dietary changes gradually, sugar has the unique ability to inspire cravings which are refueled every time you give into them.

The only way to break the cycle is to stop feeding the fire.

Once your sugar tolerance has normalized you can reintroduce it in small amounts, so long as you are sure you are eating for pleasure and not from habit.

Quitting sugar cold turkey is not entirely easy, however, even if you know the break is temporary. Cravings can be incredibly intense and make sticking to your resolution very difficult. If you hope to get through it, you must have a strategy for diverting yourself from temptation.

Start by removing all sweets (especially your weakness) from the house. Do a full sweep, no secret stashes can stay. If you do not want to throw things out, try giving them away at work or even sealing them up and putting them somewhere you can’t get to them. Making it impossible to cheat will greatly increase your probability of success. Don’t rely on willpower.

Once you have removed your most likely pitfalls you need a strategy for dealing with cravings. For this it is important to understand clearly why you want to avoid sugar, what you are making the effort for.

If you aren’t sure why limiting sugar is necessary I recommend spending some time educating yourself on the subject. If you’re a visual learner, check out the first part of this video about the potential dangers of sugar and the theories of Dr. Lustig and Gary Taubes.

Being completely convinced you want to change your habits makes following through on your resolution much easier.

The next step is deciding on alternative behaviors to divert yourself from cravings—they will pass eventually so all you need to do is distract yourself for a bit while they are strongest.

What works for you will depend a lot on your own personality and needs. For many people, sugar snacking is triggered by certain environmental cues such as location or time of day. In these situations, diversions should be planned in advance to avoid slipping into habitual behavior.

Planned distractions from habitual eating can include taking different routes between locations (to avoid walking by that bakery), substituting behaviors (there are no cookies at the gym) or choosing different foods or beverages during certain activities (mint tea instead of ice cream?).

Experiment with different alternatives and figure out what works best for you. Foods with oil and protein tend to be satisfying and quench cravings, if hunger is a problem for you. Exercise is the golden ticket for others. For me personally, sugar cravings are best satisfied by fresh fruit, especially those with a lot of fiber like apples and oranges.

Make sure your alternative foods and activities are things you enjoy. If they aren’t you will eventually abandon them for your old habits. Ideally these avoidance behaviors will completely replace your sugar habit and become your new healthstyle.

As you cut sugar out of your diet, also be sure to avoid hidden sugar sources. Stay away from sauces and condiments that are really desserts in disguise, e.g. honey mustard, teriyaki, etc. Added sugar is very common in restaurant sauces (especially mid-range chain restaurants), so you might want to avoid eating out all together for a few days if you can swing it. You should also avoid sugar substitutes.

When you have completed your four day sugar fast (go a week if you can), your cravings should have subsided substantially (the first 2 days are the worst). Continue to keep sugar minimal and actively avoid situations that cue you to eat sweets. Integrate your new behaviors into your healthstyle until the new habits replace the old ones. This process takes 6-8 weeks.

During this time get in the practice of asking yourself why you are eating sugar before you put it into your mouth. Are you eating from habit? Because of circumstance? For a special occasion? Because everyone else is?

The purpose of this exericse is not necessarily to stop yourself from eating, but to understand the reasons behind your behavior. The goal is to find a way to allow sugar into your life as a treat and not a necessity.

As you ween yourself off sugar, your tastes can change dramatically. All my life I had a sweet tooth, but over the past several years my taste for sugar has diminished and most drinks and desserts are now far too sweet for me. Consequently limiting sugar is not something I need to think much about, except during holidays and special occasions. Even then I don’t give it much thought, it happens naturally.

Besides eating whole unprocessed foods, cutting your sugar intake way down is probably the single best thing you can do to improve your health. If sugar is a problem for you, eating less of it should be one of your highest priorities.

Everyone knows we should all be eating healthier, working out more and generally making better life decisions. Problem is, once you actually start doing those things, nobody wants to hear about it.

As ridiculous as it sounds, people don’t like to know when other people are taking the initiative to do things they know they should be doing themselves but haven’t had the discipline to start. If you aren’t careful about it your best efforts can earn you enemies or worse, lose you friends.

No one likes to be reminded about their own failings, so how do you maintain your healthy habits without offending the people around you who don’t appreciate your efforts?

Over the past several years I’ve used a handful of different tactics to deflect the worst intentions of naysayers. Here are the one’s I’ve found to work best.

How To Eat Healthy Without Being A Buzzkill

1. Don’t get defensive

The worst thing you can do when some criticizes you for ordering a salad is to get defensive and start preaching your nutritional superiority. I’ve seen this done, and it doesn’t end well. Whatever you do, keep an upbeat tone and maintain perspective. Not everyone understands the importance of their daily food decisions, and it’s not your job to educate them.

Instead of:

“At least I’m not going to have diabetes by the time I’m 40!”

Try:

“Actually the salad here is tasty as hell, have you tried it?”

2. Use humor

Without getting defensive, you can still jab back a bit so long as it is clear you’re being playful and joking. If someone asks why you aren’t eating from the giant Costco tub of brownie bites, cracking a joke about how it isn’t your vice of choice today can break the ice and get the attention off your healthy decision.

Instead of:

“Eeeewwwww. Haven’t you ever eaten a REAL brownie?”

Try:

“Thanks, but I’m saving my heart attack for the weekend.”

3. Creative ordering

No one will make fun of you for making healthier decisions if they don’t notice. Ordering a burger and dissecting apart the meat from the bun is certain to draw attention, but there are plenty of things you can order that won’t attract a second thought.

Instead of:

“Do your meatballs have breadcrumbs? Ok, I’ll have the spaghetti and meatballs without the sauce and without the spaghetti, and with extra meatballs. Oh, and a side of steamed broccoli please.”

Try:

“I’ll have the steak and spinach salad with a glass of your best California cab please. And can I get some blue cheese with that as well?”

4. Happy honesty

It’s hard to say bad things about someone who is clearly happy and at peace with their decisions, especially if it’s clear you aren’t being motivated by your ego.

Instead of:

“I’m choosing salad because I’d really like to lose 10 lbs this year so I don’t end up looking like you.”

Try:

“I’m just trying to eat a little healthier these days to see how it makes me feel.”

5. Harmless lies

Honesty is always the best policy, except when you’re trying to get your jerk friends off your back so you can enjoy your lunch.

Instead of:

“I’m eating a smaller lunch today so I can hit the gym later.”

Try:

“I had a really big breakfast, I’m just not that hungry.”

6. Share alike

If you know in advance you’re going to be bringing your own food, you have the advantage of having a meal that looks, smells and tastes much better than anything your friends will find at the corner sandwich shop. Show off your amazing new flavors by bringing enough of something delicious to share.

Instead of:

“Yuck, I can’t believe you’re eating that disgusting excuse for a calzone.”

Try:

“Have you tried the mandarins from the farmers market this season? They’re freaking amazing! Here, I have an extra one.”

7. Accept and nibble

Friends can be very crafty and sometimes try and force you into eating unhealthy food by offering it to you point blank. Cheap office birthday cakes are particularly offensive. Politely turning down the objectionable substance is one strategy, but can easily backfire. Just gratefully accept the food and pretend to eat it.

Instead of:

“Just a small piece for me please.”

Try:

“Mmm…thanks.”

Take one bite, then keep smiling and continue the conversation while leaving the food nonchalantly on the table. When everyone else if finishing up, subtly drop it in the trash without making a fuss (trust me, nothing is going to waste). By that time, no one will care what you’re doing. If someone does say something, just blame it on how big the piece was.

8. Don’t offer unsolicited advice

No matter how tempting it is, don’t be the reverse jerk. Only offer nutrition advice to friends if they explicitly ask you for it, otherwise keep your trap shut. The best thing you can do to help your friends is show them what good healthy food looks and tastes like by setting a good example, then let them watch for themselves as you lose weight and get in shape.

Instead of:

“You know, that Lean Cuisine isn’t going to help you get rid of those thunder thighs.”

Try:

“Wow, I have lost weight! Thanks for noticing! Yeah, I’ve been reading this site called Summer Tomato. It’s great, you should check it out.”

How do you deal with friends who don’t want you to eat healthy?
