Joel Fuhrman, my nutritionist guru, maintains that the best diet for longevity is one with a slight calorie deficit.

I use cronometer to record everything I eat, and it gives me a very precise picture in terms of calories. I know that if I eat 2100 calories, my weight remains extremely stable, so in order to attempt this slight calorie deficit routine, I’m shooting for between 1800 and 1950 calories.

So far, I’ve found that it is easy to do, as it only takes taking out one or two foods that I normally eat to meet the requirement, and I can alternate which of those foods I’m going to remove, so that the nutritional profile remains very consistent.

For weight loss purposes, I think a slight calorie-deficit approach is much better than severe dieting with large calorie deficits, because with severe dieting, one typically ends up binging and regaining whatever weight was lost in the first place. But with a slight calorie-deficit, one is getting plenty of regular nutrition, and so there is much less risk of uncontrolled binging for regaining weight that was lost very gradually.
