# Yogurt consumption linked to less visceral fat in UK twin study

A study of more than 1,000 twins in the United Kingdom found that regular yogurt eaters had less visceral fat and distinct gut microbiome changes compared with non-consumers, published in BMC Microbiology on Sept. 9, 2026.

Regular yogurt consumption is associated with less visceral fat and measurable changes in the gut microbiome, according to a study published in the journal BMC Microbiology that analyzed clinical and nutritional data from more than 1,000 twins in the United Kingdom, mostly women.[^1]

The study compared yogurt consumers with non-consumers and found differences in both body composition and microbial profiles, though the design does not establish causation.[^1] Melissa Prest, a nutritionist and spokesperson for the Academy of Nutrition and Dietetics, noted that a typical serving of Greek yogurt can provide 15 to 20 grams of protein.[^4]

The read here is that the twin design strengthens the observation by controlling for genetic and shared environmental factors, but the findings are associative, not causal. The study adds to the evidence base for yogurt as a component of dietary patterns aimed at reducing visceral adiposity, though the mechanism through the microbiome remains to be confirmed in intervention trials.

A separate clinical validation cohort of 2,745 patients from the Mass General Brigham Biobank did not replicate most of the associations found in the UK Biobank, possibly because clinical patients have more complex medical histories and are imaged under varying protocols, the authors noted.[^8]
