Low Carb Diet Part 2

It is important to keep in mind, that DIT or the thermic effect of a meal only represents 3-10% of total daily energy expenditure (TDEE). So we must keep things in perspective. Basal or resting metabolism accounts for up to 70% of TDEE and energy expenditure from exercise is responsible for the rest. Logic dictates, therefore that these two take precedence over DIT.The other big important factor in weight loss is the reduction of daily food intake. Lets look at the input/output equation: x (Input) y (Output) = z. Daily output and total daily energy expenditure (TDEE) are the same thing. If you ate fewer calories (x) than your body burned (y), z would have a negative value. If you consumed more calories than your body expended, z would be positive. A negative balance in the equation results in weight loss, a positive value causes weight gain. Its that simple.In the above study, the high protein low fat type diet involves 2 factors of Input: Food composition and food quantity. In this diet, food composition (food selection) consists of a particular combination of macronutrients (high protein, low fat). Food intake (Input) affects the DIT which causes a certain increase (energy expenditure) on the Output part of the equation. And, as food composition varies so does the DIT. Food composition, though, can only have a limited effect on DIT. Remember DIT only represents 3-10% of the TDEE (Output). And food composition (high-protein, low-fat), accounts for a percentage of DIT, which includes even a smaller value. Food quantity, on the other hand, can have a tremendous effect on the equation as it increases, the balance becomes more positive. If it surpasses TDEE then you gain weight - quite independently of DIT. Therefore, there can be a downside with respect to DIT involving the high-protein low-fat diet or any diet for that matter. With this diet, as protein intake increases so does the DIT. The problem is, however, that the food quantity (Input) also increases. The point here is that there is a limit to the amount of protein you can ingest before your body starts storing it as fat. Because DIT doesnt account for expending a lot of calories (3-10% of TDEE), and food composition (high-protein, low-fat) accounts for a percentage of DIT, theres only so much protein you can ingest before you start getting a surplus of calories. And excess dietary protein just as excess carbohydrate or fat is stored as fat in the bodys adipose tissue. The only other factor that can compensate for the excess of protein intake is an increase in exercise participation. Although, that would defeat the purpose for obvious reasons.
