Only as a last resort, if the body has no other option, it may also burn a bit of body fat” To sum up, the amounts of food a person consumes is very important.Another way we can prevent obesity is by exercising. Physical activity is very important for the human body. According to Mayo Clinic, “Exercise can help prevent excess weight gain or help maintain weight loss. When you engage in physical activity, you burn calories” These activities help stable your weight while you are eating healthy. Aso, physical activities don’t only help you with weight gain or loss, they help with preventing bad health conditions. The Mayo Clinic explains that “No matter what your current weight, being active boosts high-density lipoprotein (HDL), or "good," cholesterol...” This will with the health problems that were caused by obesity. In conclusion, can be stopped by exercising and eating healthy. It is very important to remember to eat healthy while participating in some physical activity everyday.
