Keto Diet Popularity Surges Again in 2026 Amid New Research

The ketogenic diet is experiencing a resurgence in popularity in early 2026, according to a recent survey by the International Food Information Council. The low-carb, high-fat diet saw a 15% increase in adoption compared to last year, driven by new studies highlighting its potential benefits for weight loss and metabolic health. Researchers at a major university published findings this month indicating that keto may improve insulin sensitivity in some adults. However, experts caution that the diet is not suitable for everyone and recommend consulting healthcare providers before starting. The trend is also being fueled by social media influencers promoting keto-friendly recipes and lifestyle tips, Reuters reported.
