And I lose at 2,000.
Everyone is different.
The key for me is nothing but whole foods, no sugar, no alcohol.
Boy... is that the truth!
I had a roommate in college that would eat a box of macaroni & Cheese and 4 eggs for breakfast.. then eat a double meat whopper with fries for lunch, and be STARVING a few hours later at dinner time. He never weighed more than 155 pounds. Still does, 35 years later.
Meanwhile, even when in college, weighing 220 lbs and able to run 4 miles and bench press 245 lbs, I GAINED weight if I at more than 2000 calories.
Today, I'm at 265. 10 years ago, I dropped 50 pounds in 6 months using Atkins. (300 >250) I gradually crept back up to the 275-285 range, by intermittently going low-carb.
In the past two years, I've been drifting slowly down by doing a couple of things.. MAINLY, just trying to eat a little slower, and STOPPING when I START to fill full, not when I'm so full I can't breath.
I still bend toward low-carb. Rarely eat potatoes or rice anymore. Eat mainly low-carb bread. But, I'll indulge occasionally. I also TRY to avoid sugar, but... will have a little ice cream if I want it.
The alcohol stays. :-) Life just wouldn't be worth it without wine. I do try to avoid "over drinking"... really, I DO try! ;-)
