That sounds reasonable. I would be interested in seeing the results of the scientific studies demonstrating the long-term efficacy of such a regimen, say, a follow-up study of subjects after a period of five years, ten years, twenty years, etc.

Once you lose the weight you go back to your maintenance calories. I know some people who have made a lifestyle change and kept the weight off but TBH most people gain it back within 1-2 years... at least that has been my experience on people I have dealt with. I would say 5% or less keep the weight off. Sad isn't it? Old habits die hard I guess.

Then there is no point in taking the weight off, unless it is a life-and-death situation, such as dropping enough lard to be eligible for a vital surgical procedure, or getting in respectable shape for that 25th graduation reunion.

It would be useful to see a comparison of the long-term success rates of various diet regimens.
