Mouse Study Finds Sugar-Free Low-Fat Diet May Harm Metabolism
A 16-week mouse study found that removing sucrose from a low-fat diet worsened glucose control, insulin resistance and liver changes, researchers said.
- On Saturday, researchers at the Endocrine Society's annual meeting, ENDO 2026, in Chicago, presented findings suggesting that completely removing sucrose from a low-fat diet may unexpectedly disrupt gut and metabolic health.
- Over a 16-week period, Dasman Diabetes Institute researchers examined 12 mice, comparing a low-fat diet containing sucrose to a sucrose-free version to determine consequences of highly restrictive diets.
- Signs of fatty liver disease and intestinal inflammation emerged in the sucrose-free group, which also developed impaired glucose control, insulin resistance, and gut microbial imbalance.
- Nneoma Oparaji noted that "nutrition is more complex and nuanced than removing a single ingredient." Ali, an outside researcher, cautioned against overinterpreting findings, stating, "Overall, I think the positive benefits outweigh the possible negative effects."
- Future human studies are necessary to confirm these dietary health implications, researchers suggest, as Acting Director General Faisal Hamed Al-Refaei stated the institute remains committed to evidence-based discoveries.

Eliminating dietary sugar may disrupt gut health and promote inflammation
Eliminating sugar from your diet may be more detrimental than previously thought, according to an animal study being presented Saturday at ENDO 2026, the Endocrine Society's annual meeting in Chicago, Ill.
Study suggests removing sucrose may disrupt gut health
Kuwait City, June 14 (SANA) Researchers at Kuwait’s Dasman Diabetes Institute have found that completely removing sucrose from a low-fat diet may negatively affect gut health and metabolic function, according to findings presented at ENDO 2026, the annual meeting of the Endocrine Society in Chicago. The study, reported by Science Daily, involved laboratory mice observed over a 16-week period and compared the effects of a sucrose-free low-fat die…
Scientists found a surprising problem with sugar-free diets
A surprising new study suggests that completely eliminating sugar may backfire. Mice on a sucrose-free low-fat diet showed worse blood sugar control, increased inflammation, disrupted gut bacteria, and signs of fatty liver compared with mice that consumed some sucrose. Researchers say the results highlight the importance of a balanced diet and a healthy gut microbiome rather than focusing solely on cutting out sugar.
