The mice were separated and put onto one of four different diets, and allowed to eat freely:\u00a0<\/p>\n<ul class=\"List_wp-block-list__nTkVj\">\n<li class=\"ListItem_wp-block-list-item__tMZ_4\">A traditional ketogenic diet: In this regimen, most of the calories come from fat. It\u2019s designed to induce ketosis, which is a metabolic state that shifts the body into fat burning.<\/li>\n<li class=\"ListItem_wp-block-list-item__tMZ_4\">A high-fat Western diet: This style of diet is often used in metabolic and obesity research. It has a very high fat content\u2014including saturated fats and calorie-dense items\u2014and is designed to mimic a typical Western-style of eating.\u00a0<\/li>\n<li class=\"ListItem_wp-block-list-item__tMZ_4\">A protein-matched low-fat diet: This diet keeps the protein content high (similar to the ketogenic diet), but significantly reduces the fat content, and includes higher levels of carbohydrates.\u00a0<\/li>\n<li class=\"ListItem_wp-block-list-item__tMZ_4\">A low-fat, high-carbohydrate diet: This diet contains very little fat, but substantially higher levels of carbohydrates, often with moderate levels of protein.<\/li>\n<\/ul>\n<p class=\"Paragraph_blockParagraph__I2kr4\">The study found that although the mice that were fed the strict, traditional ketogenic diet gained less weight than their peers on the other diets did, they also developed fatty liver disease, unhealthy levels of fats in the blood, and impaired blood sugar regulation.\u00a0<\/p>\n<p class=\"Paragraph_blockParagraph__I2kr4\">According to the <a href=\"https:\/\/www.sciencedaily.com\/releases\/2026\/01\/260127010144.htm\" target=\"_blank\" rel=\"noopener\">research<\/a>, the mice on the ketogenic diet had low blood sugar and low insulin after a few months, but when they were given carbohydrates again, their blood sugar spiked and stayed high\u2014showing that their bodies weren\u2019t releasing enough insulin, rather than becoming insulin\u2011resistant.<\/p>\n<p class=\"Paragraph_blockParagraph__I2kr4\">Senior author Amandine Chaix, an assistant professor of nutrition and integrative physiology at the University of Utah Health, said: \u201cThe problem is that when you then give these mice a little bit of carbs, their carb response is completely skewed\u2026Their blood glucose goes really high for really long, and that&#8217;s quite dangerous.\u201d<\/p>\n<p class=\"Paragraph_blockParagraph__I2kr4\">Sex-specific effects emerged too: Male mice on the ketogenic diet showed more fatty liver and impaired liver function, while females didn\u2019t develop the same liver fat buildup under the same conditions.<\/p>\n<p><img id=\"11449968\" alt=\"\" caption=\"A zootechnician holds a laboratory mouse at the University of Geneva on January 18, 2022.
