Following Dr. Kevin's plan has given my Momma - who is diagnosed with hypothyroid along with her mother - and I more energy, the easiest weight-loss we've ever witnessed, fewer issue with being cold all the time, not needing a daily nap or falling asleep at 7pm, fewer mood swings and NO mind-fog. As soon as I cheat on the program, I feel it, all my symptoms come flooding back. This book is the answer we've been searching for - and the best gift of all is seeing the difference it's making in my 69 year old mother. She has more energy and she's dropping weight quickly and she's always struggled with weight-loss and had given up because the only way, in her lifetime, to lose weight meant eating under 1,000 calories and working out like crazy...your body can't do that with age. And with this plan, she doesn't have to!!! You want an answer to your symptoms? This is it!
