In this article, self justifications for fat folks. Think about it... 10 extra pounds, right? We burn on average B calories per day and we consume E calories per day. There is a delta of D = E - B calories. If S=Sum(D, time1, time2)<-3500 we lose a pound of fat in time2-time1 and conversely if S>3500 we gain a pound of fat. That's how human beings work. So, if you're 10 pounds overweight and you want to stay ten pounds overweight? You must adjust your lifestyle so D=0. There's no magic that happens to make some people gain more or less weight, though base metabolic rates differ. So, you're 10 lbs overweight... If you cut 500 calories per day (have a salad instead of lunch... D=-500) you'll lose that 10 lbs in 10 weeks, the you can lose the weight then readjust to D=0 later. So, why not just spend those 10 weeks and look good?

Is this comment even serious? You've been on this site for nearly two years now... how many articles have there been that talk about this issue, explaining that the equation you have given (while true) doesn't work because E and B aren't necessarily independent? Consuming less calories can change your metabolism, affecting your burn rate. The body is a complex hormonal system, its not that easy.

  Of course it's serious and not the first time that I've made it here. I have read articles that attempt to criticize this model for nutrition and fitness and I have rejected them. While the body may be a complex system, simple equations often effectively model complex systems. Think about predator/prey dynamics and the relatively simple differential equations that very effectively model it for biological research. The equation I stated is approximately how the body works and it is effective for all but the most aberrant scenarios. Of course there are limits - most people cannot lose or gain more than 2-3 pounds per week. Within those limits, this model is extremely effective. E and B are effectively independent. We're not trying to solve an equation here and get EXACTLY X amount of fat loss in Y amount of time. If you can estimate D to be approximately -500/day then you'll lose approximately a pound a week. You'll have more error in your measurement of B and E than you will see as a result of a change in metabolism. edit... fix typo and note that I currently weigh 187lbs and I used to weigh 225 lbs. This model was a very effective guide for me.
