I’m often asked why I don’t put more emphasis on calories and calorie counting, particularly for people trying to lose weight. The answer is that while I think there is great value in understanding and monitoring the types and amounts of foods that you eat––especially if you’ve never paid attention––your effort is much better spent keeping a food journal than on an endless race between your mouth and the treadmill.
The idea behind calorie counting is that you write down the calories in everything you eat and make sure it stays below a certain number each day. If you want to take it even further you can monitor the calories you burn during exercise as well, and factor that into your daily allowance. In theory it helps to know your resting metabolic rate (the number of calories your body naturally burns if you sit around and do nothing all day––this is your baseline), but that involves an expensive test in which you breathe through a tube for 15 minutes. I’ve done it, it isn’t fun.
Food journaling also requires writing down everything you eat, but emphasizes portion sizes (e.g. ounces, grams, etc.) instead of calories. It can also include information like the time of day you eat, other activities related to eating (e.g. working out, watching TV, etc.), and how you feel after eating. In Foodist I recommend keeping a food journal for at least two weeks to build awareness of what, why, when and how much you eat. The ultimate goal is to help identify the habits (along with their triggers and rewards) that shape your healthstyle. You can then use this information to build on what works and learn from what doesn’t.
While I would never tell anyone to stop counting calories if it works for them, here are seven reasons I think keeping a food journal is more effective for most people.
