It seems to me that the best time to do weight control is before you get very overweight. I have been about 40 pound overweight for 30 years. One time I posed for a picture with a pregnant woman in my office, belly to belly, and we looked about the same. I decided last year I was going to lose some weight, so I cut out snacks and cut my food intake in half, and lost 20 pounds over six months or so, but I am stuck at my present weight, and it goes up and down like a cork in a rough sea. It is hard to maintain that discipline, and I sympathize with truly obese people who have so much further to go. It seems to me that the solution to overweight is to eat fewer calories than your body uses, and to do some exercise, even walking. My nutrition researcher daughter tells me that there are medical reasons why some people cannot lose weight, and those people in this category who wish to lose weight should seek medical advice, but I remember a radio interview with a doctor who specialized in weight loss. When the interviewer asked what the most basic thing to do to lose weight might be, the doctor replied, “My friend, eat less!”
