Intermittent fasting really works! This, coupled with eating more healthy fats (nuts, avocados, salmon, medium-fat dairy), medium protein, and limited carbs has dropped me 15 lbs in 3 months. I feel better, have less hunger, and have much less desire to eat/drink items with tons of crappy sugar.
At some point this summer, I plan to try a full week.
I cannot recommend this book enough.
