It's based on the fact an 'average' adult needs circa 2000-2200 calories a day to maintain their weight. By reducing that to 1600 it will create a deficit where you will obviously start to lose weight purely on the diet alone. 400 calories a day over a 7 day week is 2800 calories. Add to that the exercise regime where you are burning anything from an additional 200 - 400 calories per session that pushes you over the 3500 deficit each week, which is the theoretical equivalent of a lb in body weight loss. I was also summarising, as for very small women he suggests slightly less than that.
Obviously if you are seriously struggling and losing focus/lethargic etc then more food would be a sensible choice, but it's more about eating the right things within the plan so you get more from your calories. The plan comes with a recipe book with some excellent suggestions.
Thx for the reply.
So the answer is a "Average" adult.
