Automatic summary · not editorially reviewedIn obese male mice on a high-fat diet, seven strength-training sessions were linked to less mesenteric fat and smaller fat cells than in sedentary mice, without overall weight change, the description reports. [1]
Obese male mice were divided into sedentary and exercise groups, and both groups continued the same diet during the study. [1]
Despite no change in overall body weight, exercising mice had less mesenteric fat and smaller fat cells than sedentary mice. [1]
The researchers say future studies will test whether these early molecular changes persist with longer training and how exercise affects other fat deposits. [1]
Obese male mice, diet and training setup
The description reports a study from the State University of Campinas in Brazil, published in Life Sciences. Male mice were used, and some became obese after a high-fat diet. The obese mice were split into a sedentary group and an exercise group; both kept the same diet during the study. The exercising mice completed seven strength-training sessions by climbing a 70-centimetre staircase with weights attached to their tails: 20 climbs per session at loads equal to 70% of their maximum capacity. [1]
Less mesenteric fat without weight change
The researchers focused on mesenteric adipose tissue, a type of visceral fat around the intestines. The description states that overall body weight did not change, yet exercising mice had less mesenteric fat and smaller fat cells than sedentary mice. Molecular analysis reportedly showed activation of processes involved in lipolysis, the breakdown of stored fat, with increased interaction between the proteins ABHD5 and ATGL, which help break down triglycerides stored in fat cells. Expression of the Scd1 gene, which contributes to fat production, was also reduced. [1]
Mouse findings and open questions
According to the researchers, these findings challenge the view that exercise brings health benefits only when visible weight loss occurs; strength training may start metabolic changes before the scale moves. The description notes that future studies will examine whether these early molecular changes persist with longer training and how exercise affects other fat deposits, including fat around the heart. The results come from mice, so they do not establish the same effects or health benefits in people. [1]
