No they do not work. I've spent a fortune on it and it was a waste of money and it did not help one bit. Nice people there though and they say it needs time. That's nonsense if it will work, it'll work right away or at least you'll notice some improvement.
I like the company but don't like their products because they don't work. Trust me on this. Just cut the sugars and fats including natural fruit sugars. Do not use oils for cooking.
