"Never step on a treadmill again..."
One of the better books I've read about combining diet and exercise for losing weight and keeping it off long-term. Practical tips combined with simple scientific and psychological principles.
Principles include things like: mindless exercise leads to forgettable results and mindless eating leads to memorable weight gain. Build lean muscles via strength training to boost your metabolism, a natural calorie burner. If you only do cardiovascular exercise you never hit muscle failure, therefore you don't build muscle; you'll also risk more injuries, be more bored, and create a bigger appetite — which leads to eating more.
To lose weight, the author suggests (and I've read the same thing in other books) aiming for a daily caloric deficit where you burn more calories than you consume. Once you reach a desired body shape or weight, you can then balance the equation to maintain it long-term while knowing you'll have good and bad days as life goes.
Eating tips: there are no forbidden foods, because you will crave it, and once you go back to "normal" eating, you'll need to find a way to eat anything that you can stick with forever. Low carbohydrate diets don't matter as much as low calories — you'll need to watch calories, meaning portions, in any kind of food. However, it's good to avoid or eat small amounts of processed carbs like white rice, pasta, bread, cookies, and cake; instead find high-fiber, complex carbs as they make you feel fuller and more satiated on fewer calories. Eat right before and right after exercise to restore muscle glycogen and speed up recovery. Space meals out with snacks so that you don't either get super hungry or overeat before you need to.
The book also covers related factors such as getting more sleep, reducing stress, drinking the right amount of water. Keeping track with things such as sharing your plan with friends and family, a scale you weigh in on each day at the same time, and how your clothes fit — all to make sure you keep on track. Good stuff!
