Based on the concept of caloric density, which states that some foods have few calories in proportion to their size (say, a lettuce), while others have lots of calories packed in small portions (a regular chocolate chip cookie comes to mind), Volumetrics divides foods into 4 categories based on their calorie/volume ratio, and is perfect for people looking to binge on some foods while still shedding pounds. However, as with the calorie counting approach, Volumetrics does not take into account the quality of the calories, prioritizing quantity instead. The app Noom and Weight Watchers (both reviewed above) share similarities with this diet theory.
Another healthy change that will help you look better is to cut back on salt. Sodium causes your body to hold onto excess water, so eating a high-salt diet means you’re likely storing more water weight than necessary. If you’re in a rush to lose weight fast, cut out added salt as much as possible. That means keep ditching the salt shaker and avoiding processed and packaged foods, where added salt is pretty much inevitable.
Phase 2: During this phase some carbs are back, so you have to watch out for any weight gain. (Following the strictness of Phase 1, you might be inclined to overeat your favorite carb-filled foods). You’ll get to eat no more than 50 grams of “good carbs” per day, including whole grains, beans, and fruits. Still, the bulk of your diet will consist of lean proteins, good fats, and vegetables.
Popularized by the documentary Forks Over Knives, the Ornish diet is a low-fat, plant-based diet plan based on whole grains, vegetables, fruits, and legumes. It's based on a lacto-ovo style of vegetarianism, allowing only egg whites and nonfat dairy products. It's packed with vitamins, fiber, and lots of filling plants to keep you satiated. Some studies have shown it can reverse heart disease and have beneficial effects on other chronic health conditions. (BTW, there is a difference between a vegan diet and a plant-based diet.)
