In 2025, Lucas Santos and a team from Brazil studied Wistar rats fed a high-fat diet from weaning to mimic obesity. They split them into four groups: standard diet, standard diet with extra-virgin olive oil (EVOO), high-fat diet, and high-fat diet with EVOO. They checked body weight, blood sugar, satiety, and brain inflammation markers in the hypothalamic arcuate nucleus.

In 2025, Maya K. Vadiveloo and a team from the American Heart Association reviewed studies on ultraprocessed foods like chips, sodas, and ready meals. They looked at how these foods, often high in fats, sugars, and salt, affect health in the US where 55% of calories come from them, rising to 62% in youth.

In 2025, HJ Jeon and team from South Korea studied 661,122 people using the Korean National Health Insurance Service data. They compared 4,664 patients who had their gallbladder removed to 13,992 matched individuals who didn’t, over 5.35 years, to check for metabolic dysfunction-associated steatotic liver disease (MASLD), a fatty liver condition tied to obesity or diabetes.

In 2025, Bruna Bombassaro and team from the University of Campinas reviewed how dietary factors like caffeine, capsaicin, cinnamon, curcumin, resveratrol, and fatty acids (EPA, DHA, oleic acid) activate brown and beige adipose tissues (BAT) to burn calories via thermogenesis.

In 2013, Manfred Lamprecht and team from Graz, Austria, studied 34 obese women in a 12-week trial. They split them into four groups: one got a fruit/vegetable juice powder concentrate, another got the powder plus exercise, a third just exercised, and the last got a placebo. They measured inflammation, oxidative stress, and blood flow markers.

A 2025 report in EMJ Dermatology highlights growing evidence that severe psoriasis is strongly linked to metabolic syndrome—a cluster of conditions like high blood pressure, high blood sugar, obesity, and unhealthy blood fats.
