I have got to lose weight super fast. what to do?

Why super fast??: Evaluate why you are losing in the first place. Speed shouldn't be a factor. Keep track of what you put in your mouth with a food journal and begin to eliminate foods with added sugars and fats. Cut back your food intake while increasing your exercise levels - shoot for 30min/day. Eat more fruit and vegetables. Drink water before meals. Don't skip meals, choose lean proteins and healthy carbs.

Not a good idea: Fast weight loss is an ingredient for fast weight regain. There are circumstances where you need to lose weight fast (i.E need to have emergent surgery...) in which case a very low calorie diet might be prescribed but you will need to do this under strict supervision of a physician. Otherwise, the best way to go is to gradually lose the weight so that you can keep it off. Good luck!
