No, no no no. Eating that little each day is not advisable if you’re trying to lose weight. Generally speaking, active guys can lose weight at 2500 calories a day, and active girls can lose weight at 2000 a day. If you create too much of a deficit, you start to mess with your metabolism and hormones in a bad way. For yourself specifically, find one or more “TDEE Calculators” and determine roughly how much you should be eating per day to maintain weight, then subtract about 1-2x your lb body weight in calories.
Here’s the thing, for one reason or another everyone is convinced that “2000 Calories a Day” is this perfect ideal for what human beings should consume. It’s not. There are too many variables for that to be true. The more you weigh (both fat and muscle), the more calories you need per day. The more active you are, the more you need. Whether you are a man or woman makes a difference, and whether you are young or old makes a difference. Many people who are “dieting” are eating far less than they should, and they have problems because of it. Problems sticking with it, problems seeing results, and problems with their metabolism rapidly slowing down to ensure death isn’t around the corner. Does 2000 a day apply to some people? Sure. Does it apply to everyone? Hardly.
I myself used to believe in “2000 Calories a Day”, I also found it hard to stick with it and see results. Why? Because my body needed more. For the past five months or so I’ve been consuming about 2700 Calories a Day and I’ve (very) slowly been losing weight. How? I’ve been strict about sticking to that goal, and getting the proper nutrition I need within that goal (protein, fiber, vitamins, etc). I’ve also realized that exercise is the only way for me to obtain a physique that I want. I lost weight until I had an epiphany about the fact that I was losing what little muscle I had. Weight loss is rarely the true goal, fat loss is. If you want to ensure that you are only losing fat, then you’ll want to exercise. You don’t have to do anything crazy though, muscle maintenance is much easier than muscle building, but an effort will need to be made either way.
Here is the progress that I’ve made over the past few years, I’ve learned a lot through it all, and I’m still learning. My hope is that I can help others with what I’ve learned, that’s all.
