There’s so much that goes into play are you active or not and depending on your goal. You need to feed your body the calories it needs not reduced calories. I’ll lose more weight and eat a lot more on a healthy diet than on a reduced calorie diet. On a reduced calorie diet you can easily drop 20 to 25 lbs. then you stick and usually gonna bounce right back up usually. Your body will be weak deprived of nutrients and your metabolism will be destroyed. Weight management is delusional, body weight is not a good measure of health. Low calories is counterproductive and not healthy in the long run. It starves your body, causes you to reduce muscle and destroys your your metabolism. I’d rather eat more be healthier and at optimum health. Occasionally, not long term reduced calories can be good. 300 g of protein is not the same functionally for the body as 300 g of carbs.
