During weight loss, if liver and kidney functions are normal, we can recommend a high-protein diet to our patients. This type of diet is characterized by a noticeable weight loss effect. In the high-protein diet, it is required that patients should opt for high-protein foods more frequently and whey protein can be added if necessary. Among high-protein foods, we recommend that patients use skinless chicken breast because it is rich in leucine, which is beneficial for fat reduction and muscle gain, thus it should be chosen more often during weight loss. During weight loss, it is also important to ensure a balanced diet and variety in food choices. We also suggest that patients can incorporate whole grains, skim milk, boiled eggs, lean beef, steamed fish, beans and their products, fresh green leafy vegetables, and low-sugar fruits, among others. Additionally, forming a good habit of exercising is essential to maintain an ideal weight.
