What is the best way to lose weight im 225 lbs 6feet tall i want to lose 30lbs is that too much to lose ?

No. you can do it by exercise, stopping all junk food and sodas, avoid eating in-between meals, eating regular healthy meals in moderation which includes fruit and vegetables. You can do it!

Diet and physical exercise remain the mainstay of any weight loss program. Joining a weight loss group or program may help in keeping you focused and keeping up with realistic goals.

The goal of losing 30 pounds is a reasonable one. Aim to reduce about one pound per week so that you can sustain it. Consulting a nutritionist would be useful as would be joining a support group like weight watchers. You need to reduce your food intake and increase physical activity/exercise. Wish you good health!
