Scientists discovered that more muscle and less hidden abdominal fat are linked to a younger biological brain age. Deep visceral fat appeared to accelerate brain aging, while muscle mass offered a protective effect.

Scientists found that high-flavanol foods can prevent the decline in blood vessel function that occurs after prolonged sitting. Even physically fit men weren’t protected unless they had consumed flavanols beforehand. A cocoa drink rich in these compounds kept arteries functioning normally. Everyday foods like berries, apples, tea, and certain cocoa products could offer a simple […]

A research team has found that specific immune cells can connect with muscle fibers in a lightning-fast, neuron-like way to promote healing. These cells deliver quick pulses of calcium, triggering repair within seconds. The mechanism works in both injury and disease models. The discovery could inspire new treatments for muscle recovery and degeneration.

Ultra-processed foods are rapidly becoming a global dietary staple, and new research links them to worsening health outcomes around the world. Scientists say only bold, coordinated policy action can counter corporate influence and shift food systems toward healthier options.

Researchers have uncovered a surprising new role for the HSL protein: beyond breaking down fat, it also works inside the nucleus of fat cells to keep them functioning properly. When HSL is missing, fat tissue doesn’t expand as expected— instead, it shrinks, leading to lipodystrophy. This unexpected discovery helps explain why both obesity and fat-loss […]

Researchers found that hot tubs raise core body temperature more effectively than traditional or infrared saunas, leading to stronger boosts in blood flow and immune activity. Only hot-water immersion produced measurable changes in inflammatory markers. These effects can persist beyond the session, suggesting a sustained health benefit. For anyone unable or unwilling to exercise, heat […]

Scientists are uncovering how GLP-1 drugs like Ozempic and Wegovy act on brain regions that control hunger, nausea, pleasure-based eating, and thirst. These discoveries may help create treatments that keep the benefits of weight loss while reducing unwanted side effects.

Rutgers scientists found that metformin can blunt many of the metabolic and cardiovascular improvements normally produced by exercise. Participants who took the drug saw reduced gains in fitness, blood vessel function, and glucose control. The interference may stem from how metformin affects mitochondrial activity.

Ultra-processed foods, already known for their links to health problems in adults, are now shown to harm young adults too, disrupting blood sugar regulation long before illness appears. A four-year USC study following 85 participants found that even modest increases in UPF consumption drove up the risk of prediabetes and insulin resistance, two early markers […]

By reactivating a long-lost gene, researchers were able to lower uric acid levels and stop damaging fat accumulation in human liver models. The breakthrough hints at a future where gout and several metabolic diseases could be prevented at the genetic level.
