Basically what you do is eat ‘high’ calories (1500-2000 for you most likely) on days when you do heavy exercise (weights, calisthenics, etc) and then next day eat low calories (800-1200) and do your cardio whatnot, though not too much, cardio will eat away muscle, just look at marathon runners. Usually works best to do Monday, Wednesday, Friday high calorie days and the rest low, but I don’t know your schedule.

On heavy exercise days you want to eat something like 100-300g carbs, 100g or so protein and the rest fat, then on cardio days eat less than 50g carbs and heaps of protein, something like 150g for you. Low carbs makes your body use fat for fuel and the high protein ensures your brain is sufficiently fueled, the heavy exercise makes the muscles want to store carbs more, so eating carbs on those days makes more carbs go into the muscles rather than into fat.

Yes, diets like this suck, there’s little variation you can do, but they work, I do it myself when I want to lose fat and keep/gain muscle.

Hope this helps and good luck!

I found out just recently, that’s it is impossible to do both lose fat and gain muscle at the same time. To lose fat, you should be eating low carb, low fat, and eating fewer calories than you are normally eating now. Also, doing a lo of cardio, and lifting weights.

To gain muscle you should be doing little to no cardio, but lifting weights. Eating high calorie, higher carbs, and higher fat.

It is recommended that you try to accomplish your goal in two phases. Trying losing fat first, and then work on gaining muscle, or vice-versa. The expert called it the bulking up phase and the cutting up phase. Hope this helps!

Body structure is often genetic, and we’re not all put together the same. Be the best YOU that you can, and know that what’s best for your body is rarely what somebody else looks like. I envy your energy and dedication.

I tried a bunch of BMR calculators and some said, to maintain my weight, I should eat 1600 WITH the exercise I do while others say I should eat somewhere closer to 2700. So I’m confused - How many should I eat?

IMPORTANT: BUT I’m currently working on trying to burn fat and gain muscle, so how many calories a day do I need to do that, less or more? I want to change my appearance, but not my weight - At least, I don’t want to get lighter, just smaller and toner.

I also do an hour pilates class every three days, and I do squats and lunges and crunches whenever I can, almost every day. Am I on the right track to getting rid of fat and gaining muscle?
