Summer Diet Plan Help?

Not what you want to hear, but Master Cleanse and detoxing are scams and fads and do not work in the longterm. You'll be basically starving yourself, your metabolism will adjust by decreasing and any weight you lose will come back quickly. Losing 20-25 lbs is a reasonable goal you could manage by September. Weight Watchers and Sparkpeople.com have great programs and resources. Good luck.
