Anyone who has ever been on any kind of diet or fat loss program knows how a typical diet progresses. The weight comes off fast and easy during the first few weeks of any diet, then it starts to slow down a bit. After a few more weeks go by fat loss slows down a little more or stops altogether. The reason this happens is because the body senses that body fat levels are dropping and food is in short supply.
As for carb choices, the aforementioned bagel should be 100% whole wheat, not white. At all times during the day, in fact, choose whole-grain foods over refined ones, the only exception being immediately after a workout, when fast-digesting carbs reign supreme for boosting insulin and replenishing muscle glycogen stores (see Law 8). Keep carbs to less than 2g per pound of bodyweight per day.
What about the calories? When they avoided eating between the hours of 7 p.m. to 6 a.m., participants reduced their daily calorie intake by an average of 238 calories. Which helps to explain the weight loss of almost half a pound a week. Interestingly, their intake of fat decreased significantly while protein and carbohydrate decreased at a more conservative rate. This leads one to believe that the subjects were not eating grilled chicken and broccoli late at night. No, their usual late-night snacks were much higher in fat.
The prevailing formula for a long time on how much fat you’re going to burn was calories in minus calories out, based on your basal metabolic rate (BMR) and exercise efforts, explains strength and performance specialist Joel Seedman, Ph.D., owner of Advanced Human Performance in Atlanta. But with all the different biochemical reactions in the body, hormonal response, and endocrine function, there are an infinite number of factors that can affect how your body is storing and breaking down calories.
