My body's response to caloric restriction defies the math behind all the weight loss calculators I've seen. I don't even know how it's physically possible. Which sucks, because I find it fairly easy to limit my calorie intake, but have to eat at nearly concentration-camp levels to drop weight, which isn't fun.

However, my body responds very well to exercise, especially strength training. Less convenient (takes time, space, maybe some equipment) but, conversely, works way better for me than any tables/calculators I've seen say it should. You might try that, if you haven't.

Have you tried a ketogenic diet (low carb)?

What helped me was a a low-carb diet. After two weeks, cravings for sweets were gone and I felt great.
