i believe its some sort of all in one gym so to speak.
suppliments that aid weight loss is fibre believe it or not. PGX is one example of this, any fibre pills with a multitude of sources for the fibre thats in them are good too.
Papain, one of the compounds in papaya, boosts metabolism, you could start eating lots of papayas, or there are many pills in the vitamin section that are papain based. cleanses from the health store will take all the excess water, chemical stores, and stuff stuck in your digestive system (some midddle aged people can have up to 12 pounds of extra stuff stored within them)
there are also herbs that you can find both in the vitamin isle and in the health food stores that will help you flush your system of excess water.
i found for me, biking was the best way to get my heartrate going and burn calories, as theres little strain on the bones compared to running. i lost 40 pounds in less than 2 months (just by biking 50 minutes-1 1/4 hours a day)
i've always been very physically conscious, due to having a visible disability, and being incredibly chunky as a youngster just made matters worse in terms of being picked on. so i started watching and adjusting my weight in middle school, and over the years have picked up many little tidbits.
i'm also hypoglycemic, so i have to watch my weight (less weight means less sugar can hide in fats, and less hypos) and makes it easier to tell when i need to start eating more iron.
in terms of things to help you along loosing the weight, a health food store will be able to help you with metabolism boosting type things, while attempting to cut out white flour will help things along even farther; and of course, excersize and water are 2 of the most important things
sorry if i came across as a know it all, just putting some sugestions that worked REAL well for me out there.
