New year, new food? Here’s what to know about the top diets of 2025

As 2025 arrives, experts break down the trending diets, highlighting the science-backed winners, the cautious choices to consider and the fads that might not live up to the hype.

It’s a new year, and as resolutions take hold, many are tossing out the chocolate and candy in pursuit of a healthier, better version of themselves.

With countless diets promising transformation — ranging from Mediterranean and keto to carnivore — how do you know which one will actually deliver results?

“It’s really important that we remember that there’s no single diet or dietary pattern that’s going to be best for everybody. So your eating plan should consider factors like your food preferences, your medical needs, your cooking skills, your budget and also have some religious or cultural influence if that’s appropriate for you,” explained Amanda Nash, a registered dietitian with the Heart and Stroke Foundation.

While there are great diet plans available, Nash advises steering clear of short-term options like cleanses, detoxes or anything that promises quick, miraculous results.

“These usually indicate that they’re going to be very restrictive, they’re not going to meet your nutrient needs and they’re not going to be sustainable in the long term,” she said.
