Highly impressed
This product is amazing. It really does help slim down the waist line when used correctly and with good eating habits. Working out will enhance and speed up the process and slim down your midsection and love handles. I’ve been on this product for four months and went from a 48 to 33 waistline but I work out as well. This is my new vice.

1st drink, 1st day impression
Today is my first day trying it. First off, the directions say mix with 6-10 oz of water. Mix with AT LEAST 10 oz and go from there. The formula mixes well in the water but I drank it with 8 oz and it was thick. Second, the taste is ok. It’s a lot better than what I expected. The Mixed Berry flavor tastes kinda similar to blueberry mini wheats. I’m impressed overall so far. But, I did expect a bigger energy boost from this. It is only my first day so it may improve with more use but we’ll see

I do like this product, it takes a little while to notice the results. If anything it will keep you regular during the holidays and you won't have to feel guilty of skipping the veggies dishes.

A shopper on Oct 3, 2018
BEST ANSWER: Yes, it works wonders. I’ve been using this consistently for four months with a 90% very good eating habit very moderate workouts and went from a 48 to 33 waistline.

Let’s just say I no longer have a muffin too with my tight jeans and all of jeans including the ones I couldn’t even close, now have a gap in the waist area.
