When you diet and restrict your food intake, it doesn't necessarily bring about good health. In fact, it can even cause health problems. Focus on your general health and as that improves, you'll find that you've started making the changes needed to lose weight. Most of us ignore the need to eat for the sake of our health until a problem occurs. I really encourage you to be someone who eats for health, before you're forced to by illness.
Prevention is better than cure.
Many people set their goal to lose a certain amount of weight. This they may achieve. However, they may not be aware of what could have happened to their general health. Consider the people who deprive themselves of food, take diet pills or drink diet shakes. The goal is to lose weight and in the short term there's a good chance this will be achieved.
