The Mac Institute is amazing! They are so helpful and truly do want to help you succeed in your weight loss. I did the Mac Diet about a year and a half again and I still haven’t gained the weight back. I lost about 27 lbs in 4 weeks! The individuals working there are really there to help. Whenever I had questions they were always quick to give me an answer. I would suggest the Mac Institute to anyone! Thank you so much Macs!
