Well, let´s start to say that I'm a fat boy. Usually and easily in a dinner, I could munch down an entire roasted chicken. One day I decided to put this mess in order and started making hard exercises, but still, something was missing and it was the food bit. Jimmy Joy appealed to me by its design and colors, then I went to check the nutritional specs and seemed good. I ordered a beginner's box with lots of things but my references were really easy to get - Plenny Shake replacing my dinner and after only lunch the next day. The first day was difficult, not hard. Second and third days normal...Dinner then stayed awake around 2 hours after dinner, went to bed and.... no hunger... Will buy it again for sure, but next time want to try out the Plenny pots and the new shakes.
