Please let me know

A lot of weight loss products make some really amazing claims. From special diets to supplements, they advertise weight loss totals that really make their products look like they work. I am interested in weight loss products and fat burner because I really want to lose a few pounds, but can I trust the claims these products make and are they safe for me to take? Have any of you tried them and had any success? If so, please let me know.
