Not so sure about becoming a vegetarian or vegan? That's where the flexitarian diet comes in. You're basically adding new foods into your diet, focusing on plant-based proteins like tofu, beans, nut or soy milk, and eating less meat — but not cutting it out completely. Since vegetarian and vegan diets typically lead to weight loss, you'll see results from being a flexitarian, too: Studies show those who are mostly vegetarian or vegan have a lower BMI than full-on meat-eaters.
Earlier this month, the Endocrine Society released a scientific statement saying that people can lose weight on any of roughly a dozen diets assessed by its researchers. A study published in February, meanwhile, found near-identical weight-loss benefits from low-carb versus low-fat diets. Another paper, published just a week later, said vegetarian and Mediterranean diets are equally heart-healthy.
Talk about heart ache: high blood pressure stresses arteries, and can make you more susceptible to heart disease. To eat to lower your blood pressure, you just need to focus on heart-healthy bites. The American Heart Association recommends loading up on fruits, veggies, whole grains, low- or non-fat dairy, beans, lean meats, and fish. Bonus: no one's ever gotten fat eating more kale and beans.
