My last article, The Body’s Fat Thermostat — Part 1, discussed the concept of homeostasis and how body fat is regulated like a thermostat rather than simply the end product of Calories In — Calories Out. The level set by the thermostat is determined by multiple hormones (like most everything else in our body), rather than the number of calories we eat. It is true, however, that the types of food and the amount of food will influence those hormones, but different foods, even with the same calories, have different hormonal effects. This is why calorie counting is such an unsuccessful weight loss strategy.
