Interesting Sunshine. I am diabetic, and getting my blood sugars helped me also. Low carb helped achieve control over what I ate, as well as getting off diabetes meds.
However, that control gained by eating low carb has allowed me to eat less.. 2,000 - 2,500 calories a day. I planned less before, but binged a lot, and never really tracked it. When I sat down and actually tracked a binge, it was over 8,000 calories, and that's an extra 1,150 calories a day. I might do this 2-3 times a week, so after my 1,800 I planned daily, I would consume over 24,000 with 3 days of " 4th meals ". This added 3,400 calories a day on average, so 5,200 a day, which is why I weighed 361 lbs.
In my mind i was on an 1,800 calorie diet, but now I can see that I cut 50 % of my calories out, and that is why I started losing weight. The cause was low carb, and control of blood sugars, but I take less calories in, and now that I exercise, have more calories out.
I think there are other factors that can burn more calories, or cause us not to digest ( take in ) certain calories, but in general it is calories in, versus calories out. I think some foods take more energy to digest, like protein, so maybe you burn more, but if you sat down with a scientist, and actually studied it, you would realize that calories are either not taken in, or burned in ways we don't count. Your diet may be one which does this, which is why you lose weight.
All we count as calories out is an estimate of BMR, and exercise, which we also estimate. There are many factors, but our inaccuracy of counting calories in, and calories out, doesn't mean that calories in, and calories out isn't true. It just means we suck at calculating these numbers.
In general, if you can maintain a stable weight, on a stable diet however, then cutting 500 calories, or burning 500 calories, or a combo that eliminates 500 calories, will result in around a lb of weight loss in a week. First one needs to find a stable diet though, and get a baseline.
Yes, I do believe that different diets allow us to eat different calories to maintain weight though, so in that sense, it would mean that 2,200 calories of higher carb, low fat food would not necessarily result in the same weight loss, even if I could avoid the binges. Maybe I would have to eat 2,000 calories, instead of the 2,200 I eat on low carb.
So calories in versus calories out matters, but the type of food you eat does too. Interesting point, and one worth noting. It is easy to say eat X amount of food, and burn X - 500, and quite another to identify X, and stick to it, both diet, and exercise. I think you need control of eating, and to stop cravings/overeating before you can apply the calories in/out rule.
Rules don't mean a thing if you have no control. You just break the rules.
