I came across a eating plan for natural body builders which allocated calories based upon the individuals weight, which was to be taken once a week upon waking up. The idea being that you'd constantly be lowering the total calorie intake to match your weight loss or gain goals. The starting allocation was 11 calories per pound. This Macros would be 1.25-1.5g of protein per lb of body weight, carbs being 40-60% of the total allocation of calories less the amount for protein and the remaining balance went to fat. If after a week if weight loss goals weren't being met, you would decrease to 9 or 10 calories per pound for example.
I don't recall coming across a plan that had this constant adjustment based on weight and found it interesting. Its interesting considering the information in the article, about how people become more metabolically efficient as their weight decreased.
