"Sleep is a cornerstone of weight management because of the impact it has on your hormones that control how you burn fat, how you store fat, and how you're maintaining muscle. The better your hormone balance, the better your weight management. I work my butt off to get eight hours a night, but right now I'm at six—the show is murdering me!

At the heart of its flexible system: SmartPoints. SmartPoints derive primarily from number of calories; sugar and saturated fat drive the number up, protein brings it down. Getting a feel for the number of points that different foods typically “cost” in order to stay on your daily “budget” is a great way to cultivate healthy decision-making: A fried chicken wing is 7 points, while 3 oz. of chicken breast without the skin is 2 points. A sugar-laden Coca-Cola is 9 points, but so is a dinner-sized serving of Moroccan chicken rice and potatoes. Some foods are zero points: fruits and vegetables, skinless chicken and turkey breast, seafood, eggs, nonfat yogurt. Being encouraged to eat certain items in this way helps to restructure your mindset around food.
When you drink liquid carbs, like the sugar in soda, your body doesn't register them the same way as, say, a piece of bread, according to a review of studies published in Current Opinion in Clinical Nutrition & Metabolic Care. That means, even though you're taking in calories, your fullness cues aren't likely to signal that you're satisfied once you finish off a can. And that can lead to consuming more overall.
The Academy of Nutrition and Dietetics (AKA the top nutrition authority in America) released a revised paper this year saying that both vegetarian and vegan diets are best for people's health as well as the environment. If you're not ready to make a complete shift to meatless and cheese-less, consider "part-time" vegan and vegetarian plans, where you eat mostly plant-based at breakfast and lunch or on weekdays, and then eat fish, meat, dairy, and eggs only during designated times.
