As the wellness industry continues to expand, it can be challenging to separate genuine health breakthroughs from passing fads. In 2026, we saw a resurgence of some old favorites, like full-fat dairy and cold plunges, alongside new crazes like weighted vests and cottage cheese. But what do the experts say about these trends? And more importantly, which ones are worth incorporating into your lifestyle in the new year?
The Return of Full-Fat Dairy
For decades, the conventional wisdom has been to avoid high-fat dairy products in favor of their low-fat counterparts. However, a growing body of research is challenging this notion. According to a recent evidence review led by Canadian food scientist Benoit LaMarche, there is little evidence to suggest that the fat content in dairy products has any significant impact on heart disease risk.
"The argument against full-fat dairy is largely 'circumstantial,'" LaMarche explains. "In fact, some studies have even shown benefits to higher-fat dairy, like improved HDL cholesterol levels." With this in mind, the Biden administration's recent pledge to end the "attack on whole milk, cheese and yogurt" could signal a shift in public health messaging around dairy.
The Hype Around Weighted Vests
One wellness trend that has drawn more skepticism from experts is the use of weighted vests during everyday activities like walking or running. While the idea of adding extra resistance to your workout may seem appealing, the evidence for its benefits is limited at best.
"There's no strong scientific consensus that wearing a weighted vest provides meaningful fitness gains," says CDC exercise physiologist Dr. Samantha Rhodes. "In fact, the added weight can put unnecessary stress on the body and increase the risk of injury." Rhodes recommends focusing on more proven methods of strength training and cardio instead of relying on gimmicky fitness gadgets.
The bottom line is that not all wellness trends are created equal. While some, like the return to full-fat dairy, may be worth exploring, others like weighted vests are likely just passing fads. As you plan your health and fitness goals for 2026, it's crucial to separate the hype from the truly helpful. By focusing on evidence-based strategies and listening to expert guidance, you can make wellness choices that will serve you well in the long run.
