Keeping your body fit is very important, I am surprised to know that you have lost 20% weight. This is a lot. If someone becomes fat, it is not good to look at and diseases attack the body.. By controlling your weight, you can avoid many other diseases, including diabetes, stroke, and heart attack. We want to live, and to do this, we must take care of our bodies. Exercise is essential for good health. At the same time, diet should be controlled. Excess food causes many problems. Poor people work hard and eat less food. Therefore, they have fewer diseases. You will see many single people who are the sole earners of their families and who work hard year after year to support their families. They are less sick and have more energy. They are less likely to suffer from stroke and heart disease. This is an example of how a beautiful life can be achieved if everything is in moderation.
