I want to lose weight fast because i tried many diets and ways but nothing seems to work, i even tried marijuan?

Modify strategy: Please consider that rapid weight loss is not only unhealthy but also unlikely to provide sustained results. You will be more likely to succeed if you gradually lose weight with reduction in calorie intake, adding healthy exercise, stopping drugs and alcohol, and taking care of your body. With these daily habits you will lose weight and keep it off. Get with a nutritionist for more help. Good luck.
