For a long time I was consuming 4000 calories a day. This was between soda and various "junk foods". I was surprised to find my protein, carb and fat levels were pretty close to what they should have been however.
As per of eating healthier and trying to reduce some fat, I have completely changed my diet, eating a lot more veggies, no more soda etc.
According to various online calculators based on my height (6ft) and weight (180lbs) my body burns around 2000 calories just to function.
According to other calculators my weight on my previous diet should have been around 210lbs. However, this is obviously not the case, which makes me think my body consumed far more than 2000 calories just to function.
Given my rather sedentary lifestyle and the fact I didn't really gain weight (the weight I am trying to lose is from a few years ago where I spent a year eating a lot of deep fried foods), I wonder if my body didn't burn a lot more than 2000 calories just to function.
With my new diet I aim to eat 1500 calories a day, with the goal of burning 500 calories a day. I've managed to stay pretty close to this, at least never going above 2000/day.
Can such a drastic drop in daily calorie intake affect the speed of my metabolism (which I don't want to change) or have some other negative consequence?
