If you don't eat all the time without dieting, and you can't reach the energy required by your body's basic metabolism (that is, the energy necessary to maintain the operation of your body organs), your body will automatically store fat and consume muscles instead. Because the density of the same volume of muscle is much higher than that of fat, you will lose weight, but you will lose muscle instead of fat, which means that your body fat rate will increase (because the muscle is consumed and the fat content remains the same). If you want to make your body look better, you can only achieve it through fitness, not just aerobic exercise such as running. It is also important to lift iron in the gym. Look at those Victoria's secret models. They don't go on a diet, but they are healthy. They spend a lot of time lifting iron in the gym every day, because the muscles gained through fitness will make you look tight and healthy. You don't have to worry about building obvious muscles at all, because, because, because you women lack a hormone unique to our men, you women can't build muscles with obvious lines (unless you take hormone supplements), so please stop dieting and lose weight (to be honest, this is not called losing weight, it can only be called losing weight) and boldly go to the gym to lift iron.
