If the landlord really wants to achieve the goal of completely healthy weight loss, the method is simple: proper exercise and reasonable diet.
Generally speaking, aerobic exercise is the main exercise every week, supplemented by anaerobic exercise, with a comprehensive diet and adequate sleep.
The landlord must firmly believe that he can lose weight, but the only "disadvantage" of healthy weight loss is that it takes a long time, and many people basically have no patience before success, so if the landlord is determined to lose weight completely, please provide personal specific information, including height and weight, age, current diet, exercise and sleep.
