I love this book. I bought the kindle version a few years back but didn't follow the diet. I just finished week 1 and lost 6.6 lbs. I'm hoping to lose more than 20 lbs at the end of 4 weeks. I will start the cycle over. I love that the book has so many options of meal and snack choices. It also shows the time to eat it. I need that written out for me. I will update again after I complete the 4th week.
That means taking in fewer calories than you burn. That means making healthier choices. That means ... well, you know what that means. You know what you should eat. We all do. White flours and white sugars are the enemy. Foods like white breads, cookies, white pasta, white rice, and white potatoes are out. (The same is true for "white fats" like butter and full-fat cheese.)
Here's something else most people probably don't know: Fidgeting is good for you. It's considered a nonexercise physical activity, and it's an important way to burn energy. You get more health benefits if, in addition to exercising, you are a more fidgety, more active person the rest of the day. This means gesturing while you're talking, tapping your foot, just moving around.
