Why am I losing weight?

It's because it takes a lot of calories for your body to sustain such a high weight. The more you lose the less in calories you will need to consume. I was 350lbs and started losing on weight watchers for 9 months until I got stuck for 3 months at 270lbs. Then switched over to mfp. I like it better because it goes by calorie deficit and not just a point system. Lets me have a better idea of overall balanced food intake.

You realise the point system gives you exactly that though, right? -.- a calorie deficit, just grouped as 'points'....

Re-post when you're 50, have hardened arteries, high blood pressure, and diabetes. There is a huge body of work that shows that there are detrimental affects to eating like that. Sure you can lose weight, but what is happening inside your body is another story.

Funny, I get just as frustrated when I see people saying that it is ONLY calories in vs calories out. I think for some people, it may work. For others, it doesn't. I think there are many provedn biological reasons why calories in vs calories out does not work for everyone. There are also some terrible things in the general food supply that I think do not do our bodies good.

Great that calories in vs calories out seems to be working for you.

Agree to disagree on the issue.

ETA: I just watched watched a show where the guy ate 2600 cals per day (which is over the daily average for sedentary men), but 2000 of those were chocolate. He was very, very thin, but his cholesterol numbers were terrible because his diet lacked essential nutrients. I thought it was very interesting.

The answer is "poutine". It's magical and stuff. For real. I read it in the Journal of Stuff I Made Up, issue 47. <pokerface>

now I want poutine

I think you have the right idea...you are doing what works for you! I, myself, have cut carbs and sugar way down, and have lost over 140 lbs, because that's what has worked for me. It's the only "diet" that has ever been sustainable and satisfying to me. However, I do cheat, not often, but I do

Some background - I started at 320 pounds in October of 2012 and today I weighed in at 266. That's 54 pounds gone in less than 6 months -but...HOW? Based on this site, I'm doing everything wrong.

I eat between 2000-2500 calories a day, my macros are set at 45carbs/35 fats/20protein. That leaves me eating between 200-300 grams of carbs a day.

First of all, congrats on your weight-loss success! Second, I feel you might have stumbled into the BMR/TDEE or "Eat more to lose" strategy. Generally, MFP sets goals for you (i.e., I want to lose 2 lbs a week so it tells me I should eat 1200 cals). HOWEVER, this can be too little calories for more people's metabolism and our weight remains stagnant or shoots up. The gentleman has an interesting post: http://www.myfitnesspal.com/topics/show/654536-in-place-of-a-road-map-2-0-revised-7-2-12 that helps calculate how to eat the right amount of calories for your metabolism to burn weight. He never mentions food restriction, portion sizing, the like, just enter in numbers, to find your base metabolic rate and BOOM! More calories = weight loss.

SOO! After that long winded statement all I really think is you're losing because your eating enough calories to help your metabolism burn fat and shed pounds.
