Personally, I wouldn't trust the supplement part of it. I lost 160 lbs. over 2 years and have kept it off for 6 years. I only eat whole foods as minimally processed as possible on a time restricted eating schedule. That's what works for me. Stop eating all processed sugars and highly processed foods and you will lose the weight without whatever supplement they are selling. I'm not saying all supplements are bad, just that you want to be very cautious using them accounting for their long-term effects and even the manufacturing process used to make them.
