The 2019 rankings include 41 of today’s most popular diets. New to the list this year is the Nordic Diet, a plant-heavy eating plan that incorporates Scandinavian traditions and ranked 9th best overall. Here’s how the rest of the rankings shook out this year, and what experts have to say about the good, the bad, and the trendy. (Here’s a hint: They’re still not crazy about keto.)
Strength training is the kind of exercise that builds healthy muscle tissue. Strong muscles help you to move your body more efficiently. Some people refer to strength training as “lifting weights” but there are simple body weight exercises that qualify as strength training even though they don't involve lifting a dumbbell or a weight plate on a machine.
The good news is that if you're struggling with your size, reducing your calorie intake and increasing your activity level have been clinically shown to help you lose weight. The bad news is that there are no shortcuts and no short-term fixes. Fad diets, herbal supplements, "fat-burning" pills, and highly restrictive diets don't work for long, if at all, and some may cause more harm than good.
Too little sleep or too much sleep can throw your stress and regulatory hormones out of whack, and may lead to weight gain. A single night of sleep deprivation can increase levels of ghrelin (a hormone that promotes hunger), making you more likely to overeat the next day. Reduced sleep may also lead to fatigue during the day (duh) and less physical activity, which may be another reason why people who regularly don't get enough sleep tend to gain weight.
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.
