How it works: By eating foods that haven’t been processed, cooked, genetically engineered or exposed to herbicides, your body will be at its healthiest because you’re optimizing your intake of nutrients and natural enzymes. The claim is that cooking kills most nutrients and enzymes in food, although there is scant scientific evidence that backs this up. The raw food diet can also be effective for weight loss since fruits and vegetables are low in calories.
There’s a large spectrum of where people can fall on a vegetarian diet: For example, vegans consume no animal products, whereas ovo-lacto vegetarians eat both dairy and eggs. The eating style may help with weight loss, suggests a review published in August 2017 in Nutrients, but some vegans and vegetarians may become deficient in specific nutrients, such as calcium, iron, zinc, and vitamin B12, according to an article published in December 2017 in Nutrition, Metabolism and Cardiovascular Diseases.

Whether your reason for going vegetarian is ethical, environmental, or for health, one thing's for sure: weight loss can be a nice bonus. In fact, in that same study that evaluated vegan, vegetarian, and omnivorous diets, vegetarian diets were almost as effective as vegan—helping people lose 6.3 percent of their body weight compared to 7.5 percent in the vegan group in a half year. Bonus: perfection isn't necessary. Even if you fall off the wagon and break your diet (hey, it happens!) another study found that dieting vegetarians still lost more weight than dieting meat eaters.
So, in the midst of this unexpected positivity, I got an email from Pamela Peeke, M.D. She wanted to have a call and give me some advice. In a very unlike-me move, I did not get to the email. I'm very good about responding to email, which has to be one of the lamest brags of all time, but in a world full of ghosting, I'm proud of my prompt replies. But I messed up, and a week and a half later, I got another email. Dr. Peeke wanted to make sure I got her message.
