5 diet trends to steer clear of in 2017 Master Cleanse: Dieters drink a concoction of squeezed lemons, maple syrup, and cayenne pepper several times a day for 10 days. The diet is only 650–1,300 calories, and it lacks key nutrients like protein, calcium, iron, and zinc. Cabbage Soup: This diet consists of all-you-can-eat cabbage soup for seven days featuring a mix of cabbage, carrots, celery, tomatoes, peppers, and onions. While it's not as bad as other regimens, it eliminates certain food groups and who doesn't like variety? Raw Food: Here's a diet that is sort of healthy, but requires quite a bit of preparation. Rawists believe that eating foods above 116°–118° F will destroy enzymes that provide many health benefits. However, picking up ingredients will prove to be expensive and timely. Paleo: Going all meat and veggies, while cutting out dairy and legumes, may help you lose weight in the short term, but it's tough to stick to. Yogurt is a sensible treat that is light on calories and sugars, if you find the right one. Baby food: Dieters replace breakfast and lunch with about 14 jars of baby food then eat a low-calorie dinner. Talk about running on empty.
