i'm not entirely sure what is being argued here? nos is saying eat whatever you want as long as it's within your caloric parameters whereas jesus is saying eat healthily within said parameters...is that right? i'd always advocate eating healthily on a weight loss program because healthy food tends to be higher in volume than the equivalent anount of calories in 'unhealthy' foods - when it comes to feeling full, volume is almost as important as calories, it's why an apple makes you feel fuller than a biscuit despite their calorie count being almost identical. also now is the best time for him to develop healthy eating patterns...keeping the weight off is half the battle, after all. that's without even going into the minefield of the importance of macros (which are crucial and directly linked to weight loss - haven't you ever heard of the Atkin's diet...perhaps the most famous diet of our generation, it worked on the principle of removing carbs from the diet to force the body to use fat as its primary energy source, there's also the relevance of protein which i mentioned in my post above this one) and micros.
