Wellness Trends to Embrace (or Discard) in the Upcoming Year

Over the past year, the wellness industry has been flooded with new trends, many of which were championed by influencers across digital platforms. Familiar practices such as celery juicing and protein bars have maintained their popularity. However, 2025 welcomed a reemergence of traditional practices like opting for whole dairy products and employing beef tallow in cooking.

Resurgence of Full-Fat Dairy

For a long period, health advice steered clear of high-fat dairy due to cardiovascular concerns. Nonetheless, Benoit LaMarche, a food scientist from Canada, argues that the evidence against it is mostly speculative. In a study he led, all types of dairy, whether full-fat or not, seemed to impact health similarly. Surprisingly, some investigations highlighted advantages of high-fat varieties, citing studies where whole milk increased 'good' cholesterol more than its low-fat counterpart.

Experts suggest focusing less on dairy fat content, urging consumers to consider other dietary risks like excessive refined carbs or sugars. The topic emerged prominently as figures like Robert F. Kennedy Jr. advocated for unprocessed dairy products, gaining traction online, especially on platforms like TikTok.

The Weighted Vest Phenomenon

Weighted vests, marketed primarily towards older women seeking muscle and bone health benefits, raise questions about their effectiveness. Limited research shows mixed results; one study noted negligible differences in bone health between users and non-users, whereas resistance exercises showed some benefits when combined with vest usage. According to experts such as Lauren Colenso-Semple, the core science behind muscle building remains focused on consistent resistance training.

Monitoring Blood Sugar for All

Continuous glucose monitors (CGMs) promise real-time insights into blood sugar levels, even for those without diabetes. These devices, placed on the arm, have revolutionized diabetes management but are now popular for individuals wanting dietary insights. However, outcomes vary greatly, as some users reported significant health improvements, while others experienced little to no change.

Research suggests taking such data cautiously since individual responses can differ greatly. Inconsistencies, such as differing sugar level readings from identical meals, highlight possible inaccuracies in these monitors.

Methylene Blue: A Tongue-Tinting Trend

A peculiar trend sees influencers endorsing methylene blue—a dye initially meant for textiles—as a wellness hack for improved mitochondrial function and mental acuity. Though some animal studies suggest potential benefits, human trials remain inconclusive, with risks including severe drug reactions.

The Protein Product Parade

Supermarkets boast a range of snacks labeling 'high protein,' yet such claims require discernment. Without specific regulations, even minor protein quantities can warrant such marketing. Consumers are advised to check labels for accurate content, targeting products with over 20% daily value.

Beef Tallow vs. Vegetable Oils

The debate over using beef tallow instead of vegetable oils—cited by some like Kennedy as a healthier option for frying—warrants scrutiny. Experts such as Christopher Gardner argue moderation in fried food consumption is key, with added emphasis on reducing refined additives rather than focusing solely on oils.

Creatine's Comeback

Declared the 'supplement of the year,' creatine reigns supreme in muscle-building circles, although claims of cognitive and glucose regulation benefits remain weakly supported. Notably effective for enhancing muscle mass, creatine necessitates consistent exercise for visible results, with Jose Antonio from Nova Southeastern University confirming its efficacy when paired with strength training.
