I'm about 6ft high and weigh 175 pound, age 26.
For the last few years, I have lived a fairly sedentary lifestyle, easily consuming about 4000 calories per day.
What I would like to know is why if I don't burn off more calories then I take in, I don't seem to gain weight? The only time in my life I gained weight was a period where after moving to a new place I ate a lot of deep fried food for a few months.
According to various online calculators I need about ~2000 calories for my body just to function.
Should the additional 2000 calories I have been taking in contribute to weight gain? Why do they not seem to? Estimates say on my diet I should weigh over 200lbs, yet I weigh 175.
I calculated my daily calory intake based on the myfitnesspal.com website
Why would I not be gaining weight in the typical manner, especially with less exercise or physical activity than is typical?
