You eat too little. Eat what you eat. Be healthy and eat more. I suggest you change your staple food to coarse grains and eat more protein. You can eat more fish or seafood, beef and vegetables, but eat less oil and salt. If possible, add some black pepper to taste. In addition, less fat and more muscles show that the fat rate in your body is decreasing, that is, the proportion of fat is decreasing and muscles are growing again, so there is no obvious change in weight. I suggest you buy a weighing scale with a fat test rate.
