Top 5 Worst Diet Tips Ever

You know you can’t believe everything you read. And still, you haven’t eaten an egg yolk since the 90s, and you can’t touch a French fry without being saddled with guilt. Oh, and don’t even get us started on the whole don’t-eat-after-8-PM-or-else mentality. Let’s set the record straight once and for all by calling out these 5 worst diet tips — and offering up smart food rules to follow instead.

Fat makes you fat

Why that’s BS: It depends on the type of fats you’re eating, says Tricia Psota, RD, a nutritionist based in Washington D.C. “Fats in chips, cookies, and greasy foods can increase cholesterol and your risk for certain diseases. But good fats, like nuts, avocados, and salmon, protect your heart and support your overall health.”

Stop snacking to lose weight

Why that’s BS: Eating in small, frequent amounts is a great way to curb hunger, control portion sizes, and make better nutritional choices, says Mike Clancy, CDN, a personal trainer at David Barton’s Gym in New York City. “Smarter snacks like nuts, fruits, and yogurt will keep your energy levels high throughout the day.”

Load up on protein

Why that’s BS: Sorry, caveman lovers: eating lots of protein is not the key to healthy weight loss. Why? The body needs three macronutrients: Protein, carbohydrates, and fat, says Rania Batayneh, MPH, a nutritionist and author of the forthcoming The One One One Diet (published by Rodale, which also publishes Prevention), and focusing exclusively on protein for weight loss makes no sense. “

Diet Tips

Eat every 2 hours to rev your metabolism

Why that’s BS: Going four or five (or even eight!) hours between normally-sized meals will not make your metabolism slow down, says Monica Reinagel, MS, a nutritionist based in Baltimore. “Eating more frequently may help stave off hunger, which can help you fight temptation. But if you want to do this, you have to be careful to keep your meals and snacks really small,” she says. “Otherwise, eating every 2 hours can simply lead to taking in too many calories over the course of the day.”

Swear off forbidden foods

Why that’s BS: “We tend to be in ‘all or nothing’ mode when we diet and never seem to find a middle ground,” says Batayneh. “You have to realize that you can’t have pizza, French fries, and chocolate cake all in the same day, but—with careful planning—you can enjoy these foods when they are presented to you. Just don’t go for seconds and share if you can.” In fact, research shows that moderately indulging in “forbidden foods” is what keeps people from bingeing on the stuff.
