A randomized controlled trial in 180 adults found that prescribing diets high, regular or low in sweet-tasting foods for six months did not change participants’ liking for sweet taste, body weight, energy intake, or several biomarkers linked to diabetes and cardiovascular disease. The researchers concluded the results do not support public health advice that aims to reduce exposure to sweet-tasting foods regardless of whether sweetness comes from sugar, low-calorie sweeteners, fruit or dairy.

A new Cochrane review of 22 clinical trials shows that intermittent fasting does not lead to greater weight loss than standard diet advice for overweight or obese adults. The analysis, involving nearly 2,000 participants, challenges the popularity of fasting methods amid rising global obesity rates. Researchers emphasize the need for more long-term studies and personalized approaches.

A bill under consideration in the Senate aims to ban the sale and advertising of ultra-processed foods in school canteens, backed by 72% of the population according to Datafolha. While health experts support the measure to fight obesity and other diseases, opponents argue it is paternalistic and advocate investing in nutritional education instead.

Where fat is stored in the body—not only how much—is linked to brain structure and cognition, according to a large MRI study of nearly 26,000 UK Biobank participants. Researchers reported that two fat distribution profiles—one marked by high pancreatic fat and another often described as “skinny fat,” with high fat relative to muscle despite a less-obese appearance—were associated with gray-matter loss, faster brain aging and poorer cognitive outcomes.
