There are a number of reasons why garlic is a good diuretic and an excellent food to eat for those who are on a diet and are trying to lose weight. One of the reasons for this is because it tends to kill a lot of the bad kind of bacteria that resides mostly in your gut and the lining of your stomach. It can also help to speed up the metabolism which is especially good for people who want to drop a few extra pounds.
Garlic can be either consumed raw, cooked, or even taken as a capsule. There are certain places that sell garlic supplements in capsule form, so you will want to think about looking into taking them as a diuretic if you are interested in it.
