The biggest selling point of the macronutrient diet is that this style of flexible dieting allows you to enjoy the foods you love, guilt-free. Well, as long as you account for them and make sure you don’t overeat. It’s been clearly shown that total energy balance, or calories in versus calories out, is what determines weight loss. There are no evil foods or special rules about how many meals you need to eat. Food you eat after six p.m. isn’t automatically going to make you fat, and plenty of people have lost significant weight using a diet composed of mostly fast foods or processed snacks. Just because this works does not mean it’s ideal. Sure, you can lose fat, but if you want your body to run at 100 percent efficiency and be healthy on the inside as well, it’s important to make sure you’re getting the right foods in your diet. Flexible dieting doesn’t mean that you have to eat the fun foods and snacks; it just means that you can.
