High pressure of work and life can seriously affect digestive system and disturb digestive functions. Irregular lifestyle can disturb metabolism in human body and increase the burdens of stomach and intestine. Therefore, unhealthy diet, high pressure and irregular lifestyle can induce obesity.

They can use fresh vegetables, fruits, lean meat, eggs and fish to take the place of dessert, processed food and fast food and use dairy products, fruit juice and boiled water to take the place of beverages containing carbonic acid.

If people frequently eat processed food, they can not absorb adequate vitamin C. Therefore, people must stop eating unhealthy foods if they want to lose weight effectively. At the same time, people should supplement adequate and balanced nutrients like protein and vitamin E to prevent various diseases probably caused by weight loss. They can often eat fresh fruits to supplement balanced nutrients like vitamins and mineral substances, decrease the burdens of stomach and intestines and remove toxins from their bodies.
