A 42-year-old childhood obesity theory may be wrong

New research challenges the decades-old idea that children experience an “adiposity rebound” when their BMI begins rising around age 6. Although BMI returns to earlier levels, a more reliable measure showed that body fat does not rebound at all. The increase appears to come from growing muscle and lean tissue as children prepare for later growth. Researchers say this normal process has been mistakenly treated as an obesity warning sign for 42 years.

Eating one avocado a day may lower heart disease risk

A daily avocado may help lower heart disease risk in adults with obesity by reducing the number of LDL particles circulating in the blood. After six months, participants who ate an avocado each day experienced a decline associated with an estimated 4% reduction in cardiovascular risk.

Eating less protein could slow aging, major review finds

A sweeping review of more than 350 studies suggests that the protein boom may be overselling what many people actually need. Eating less protein appears to improve metabolism, reduce inflammation and cellular damage, and activate pathways linked to healthier aging and longer life.

A simple supplement could help the immune system fight cancer and viruses

Low arginine levels may allow cancer cells and viruses to slip past the immune system by reducing production of a crucial cellular warning protein. In mice, arginine-rich diets led to fewer colon tumors and milder viral infections, suggesting a simple supplement could have powerful therapeutic potential.

This once-a-week workout may help cut belly fat, study shows

A surprisingly small dose of exercise may deliver major health benefits for adults carrying excess fat around the waist. In a four-month trial involving 315 adults with central obesity, researchers found that completing 75 minutes of brisk interval walking in a single weekly session reduced body fat, trimmed waistlines, and improved cardiovascular fitness about as effectively as splitting the same exercise across three days.

Your brain may be wired to regain lost weight

Weight loss is not simply a test of willpower. The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after weight loss. This biological “memory” helps explain why many people regain weight after dieting and why medications such as Wegovy and Mounjaro can help by reducing appetite signals, although their effects may fade when treatment ends.

Cutting sweet foods doesn’t curb cravings or improve health

Changing how much sweet-tasting food people eat may not change how much they crave or enjoy sweetness after all. In a six-month trial, researchers found that people assigned to high-, low-, or average-sweetness diets showed no meaningful differences in their preference for sweet foods, body weight, or markers linked to diabetes and heart disease. Many participants also drifted back toward their previous eating habits once the trial ended.

Scientists reveal how much exercise you really need to protect your heart

Getting the recommended 150 minutes of moderate-to-vigorous exercise each week may offer only modest protection against heart attacks and strokes. A large study suggests that substantially greater benefits may require roughly 560 to 610 minutes a week—nearly 9 to 10 hours of brisk walking, running, cycling, or similar activity.

Scientists find the strength training “sweet spot” for a longer life

Just a couple of hours of strength training each week could have surprisingly powerful effects on longevity. People who lifted weights for around 90 to 120 minutes weekly had a 13% lower risk of dying early, with especially large reductions in deaths from cardiovascular and neurological diseases. Pairing strength training with regular aerobic exercise was even more impressive, lowering overall death risk by about 45%.

For decades, we were told to choose low-fat dairy. New research says otherwise

Full-fat dairy may be healthier than conventional advice has suggested. In a 12-week study, adults who ate three servings a day showed no meaningful increases in weight, body fat, cholesterol, or insulin resistance. They also experienced improved blood pressure and consumed more calcium, protein, and vitamin D. The findings suggest dairy’s complex structure may matter more than its saturated fat content alone.

A daily glass of fruit juice was linked to lower depression scores

A daily glass of 100% fruit juice or a smoothie may help improve more than just fruit intake. In a small four-week trial, participants who added one to a healthier diet showed significantly lower depression scores, hinting that a simple dietary change could also support mental well-being.

Wine, beer, or spirits? Massive study finds a surprising health divide

A study tracking more than 340,000 adults for over a decade found that heavy drinking increased the risk of death regardless of beverage type. At lower levels, however, the picture became more surprising: beer, cider, and spirits were linked to higher mortality, while wine was associated with lower risk. Moderate wine drinkers had a 21% lower risk of cardiovascular death compared with people who rarely or never drank.

New GLP-1 pill delivers up to 12% weight loss in 36 weeks

An experimental GLP-1 pill helped people with obesity or overweight lose as much as 12.1% of their body weight in just 36 weeks. Unlike injectable drugs such as Wegovy and Ozempic, aleniglipron is a small molecule that can be taken once daily with or without food and could potentially be produced more easily at scale.

Ozempic may have revealed the brain’s hidden “craving center”

Ozempic-like drugs appear to weaken more than hunger—they may also reduce cravings for alcohol and other addictive substances. Scientists are increasingly tracing this effect to the lateral septum, a brain region that helps connect memories and surroundings with rewarding experiences. Packed with GLP-1 receptors, it may act as a crucial control point between thinking about a reward and feeling compelled to pursue it. The discovery could open new approaches to treating addiction as well as obesity.

Scientists turn sheep’s wool into a material that helps regrow bone

Keratin extracted from sheep’s wool helped damaged bone regenerate in animals, producing tissue that was more organized and structurally similar to healthy bone than tissue grown with conventional collagen scaffolds. The discovery could turn an abundant agricultural byproduct into a promising new material for regenerative medicine.
