Social media continues to shape people's eating and wellness habits in 2025, and not always in a positive way. TikTok, Instagram, and Reddit are popularizing new life hacks while also bringing old, sometimes strange or dangerous practices back into the mainstream.
Among the most popular trends is “charged water.” Influencers recommend drinking water with electrolytes, fruits, and flavors for energy and concentration. Nutritionists warn: for most people, plain water is enough, but excess sugar and electrolytes can be harmful. It is better to choose fresh fruits instead of powders and juices.
The Carnivore Diet, as well as its strict version, the Lion Diet, advocates a diet of only meat and water. Scientists warn that this is an unbalanced diet: excess meat increases the risk of cardiovascular disease, high cholesterol and diabetes. A 2025 study found that regular consumption of processed red meat accelerates cognitive aging by about 1.6 years per serving.
Functional drinks and coffees with supplements like ashwagandha, Lion's Mane mushrooms, or magnesium have finally entered the mass market. Their benefits are often driven by the expectation effect: the belief that they have a calming or stimulating effect on the brain does have an effect, but there is little scientific evidence to support the effectiveness of most supplements.
The trend of "bed rotting" — lying in bed for hours, watching videos, and snacking — has moderate benefits for stress relief, but constantly spending time in bed can signal depression and disrupt your night's sleep.
The most dangerous trend is home teeth whitening with hydrogen peroxide. Using a 3% solution directly on your teeth can cause gum burns, increased tooth sensitivity, and even tooth loss. Experts advise whitening only under the supervision of a dentist.
Experts advise being cautious about popular life hacks, carefully reading product ingredients, and not blindly following trends without scientific confirmation.
