Does lipozene, or green tea pills work

No. A healthy diet and exercise works.

Nope, there is no magic weight loss pill.

There is a good diet and exercise, walking, jogging, bike riding.

Let me refraze that do they help when diet and exercising

Help with what ?

As already mentioned diet pills are the new snake oil.
By all means DRINK green tea, but pill form is a waste of time..

Personally I have switched from Soda to various green teas and have lost several pounds in weight, but that's due to NOT having the excess sugar in the sodas and NOT the green tea.
Dieting is simple:

You'll need to DEcrease your calorific intake and INcrease your aerobic activity.
(Less food more exercise)
