There are two things you have to do to take advantage of the thermic effect of food. Number one is eating 4-6 smaller meals and snacks throughout the day. Every time you eat, your metabolism goes up slightly for a few hours to process the meal. By eating more frequently you reduce the risk of overeating at a meal when you are hungry. Haven’t you noticed you tend to eat more food after going a long time without eating? It is hardwired into our primal instinct to do so. Our bodies took thousands of years to evolve into the modern day state. In early days food wasn’t always in abundant supply and there were no dollar menus. We also had to expend calories chasing prey down or foraging for nuts and berries. To protect us, our bodies became very efficient at storing body fat for times of famine. Fast-forward a few millenniums where you only have to take a few steps and open a refrigerator or drive up to a local fast food place to get a meal. We are the only animals (not in captivity) besides scavengers who spend so few calories to get a meal. Now you can see why there is an obesity epidemic going on in America.

The second part of the thermic effect of food has to deal with the macronutrients. The three macronutrients are protein, carbohydrate, and fat. Of the three, protein is the most relevant to this discussion. Your body spends more energy trying to break down proteins than it does for carbohydrates and fats. It is estimated that 25-30% of the calories consumed from protein sources are used in digestion compared to 15% for carbohydrates and 2-3% for fats. This goes to show that a calorie is not a calorie. If you were to eat equal calorie meals comprised of the different macronutrients, the protein meal would be more beneficial to your weight loss goals. Many people have seen great results by using the Atkins diet and other high protein diets due to this. In my opinion, some of those diets are too restrictive but you can up your protein intake in a balanced diet. My favorite is the 40/30/30 ratio -carbohydrates, protein, and fat respectively. That’s the percentage of calories you should get from each macronutrient in your diet. For example, if you were to eat 2000 calories daily this would be the breakdown: 800 calories (200 grams) from carbohydrates, 600 (150 grams) calories from protein, and 600 (66 grams) calories from fat.
