I love the Fast 800 / 5:2 Diet. This is a medically researched program developed by Dr. Michael Mosley. You eat regularly for five days and eat 800 calories for two days. You can incorporate intermittent fasting into your day also. Any diet program works with this program, i.e. Paleo, Keto, Carnivore. Join me on this journey to lose the last 20 lbs and keep it off!
