2 lbs a week is a 1000 calorie per day deficit. My loss was closer to half a kilo a week. I have fluctuated between 85 and 210 kg since I was 16 or so. I am now 54.

Of course I am not saying my body violates the laws of thermodynamics. After some time I succumb to cravings and begin overeating again, a bit at first and then more. I am not denying this is behaviour driven. My only point with the fruit aside was that I'm not consuming my sugar from chocolate milk or sugary breakfast cereal, not that I think fructose is exempt.

But to suggest that all I have to do is eat healthfully for a few weeks and my cravings will be gone is infuriating. I have eaten healthfully for years and years, and eaten at a calorie deficit (of healthy food) for many months at a time. And the cravings NEVER go away. I always go to bed thinking of food.

Maybe I should get a nutrition degree and then my body will conform to what your textbooks say should happen.
