    I don't know if they ever get it right, but I ate more today than ever before, about 1400 plus calories, and it said I would weigh lower than it has ever said before. Of course i won't eat the same tomorrow, but I thought it was interesting on the first day that I didn't starve myself, MfP said I would weight the least in five weeks.

    Proves to me that we don't have to eat too little to lose weight.

    Proves to me that the system is botched

    How could eating MORE make you lose more weight? It makes no scientific sense one little bit.

    The concept of eating more is not a free for all at a buffet. Most people (myself included) have a BMR that is over 1200. When you eat below your BMR (the bare minimum of calories needed to keep your organs functioning if you were in a coma!) you run the risk of doing extreme damage to your body (whether you can see if or not). My TDEE is 2706 (the number of calories for my body to maintain my weight right now) and I am eating at 1600 calories. Quite a deficit, but not so low that my body will eventually stop losing and shut down. At the least, I would get so hungry that I would give up and quit. What I have done many times in the past.

    The MFP equation doesn't hold true because 1) weight loss is not linear and 2) humans are not machines. The simple math can be skewed by hormonal fluctuations, electrolyte balance, water/glycogen retention due to exercise (which can vary according to what type of exercise/how intense/how often) and a host of other things. Setting your deficit to lose 1 pound a week, for example, is no guarantee that you'll actually lose 1 pound a week. In addition to the above factors, your metabolic rate may be different than what the algorithms calculate, you may be over- or underestimating caloric burn from exercise and/or caloric intake from foods, etc. It isn't always going to go like clockwork.
