I am really enjoying this iFast. Today is Day 4 and I am maintaining my new lowest weight. Not only that but I am feeling great energy and focus. I feel like I am 15 years younger than I did a year ago. I am looking forward to continuing my transformation to a new normal for my body. If you have not tried Ketones you really owe it to yourself to give them a try. You are worth the cost and most of that will be offset by saving on junk food and health cost.
