I want to lose weight quickly as this affecting my health now?

See Dr., and then...: Helpful weight loss diets have natural foods that take time to chew but contain few calories. Examples include carrots, celery, and leafy green lettuce (little or no salad dressing). When shopping for fruits, buy small ones no bigger than a tennis ball (fruits have sugar). Drinks without calories include water and green tea. A calorie is a calorie, but surely avoid sugar or simple starch calories.

Eating a low carb: and high protein diet will help. It can put you into a state where you burn fat rather than the byproduct of glucose. Check w/your doc first to make sure this is appropriate for you. Peace and good health.
