November 15, 2019
A high-fat, low-carbohydrate diet like the Keto regimen has its fans, but influenza apparently isn't one of them. Mice fed a ketogenic diet were better able to combat the flu virus than mice fed food high in carbohydrates, according to a new study.

Deleting a liver enzyme lowers the health risk of sweet treats (at least in mice) ... read more
October 24, 2019
Hepatic insulin resistance, caused by diets high in sugar and fat, can lead to type 2 diabetes. Researchers found that the Elovl6 gene plays a key role in hepatic insulin resistance. Deleting Elov6 in liver cells causes a rise in a specific ceramide lipid that protects mice from hepatic insulin resistance due to excessive dietary sugar. The findings could help efforts to find a targeted treatment for the condition.

Reduced food intake in old mice can no longer improve health ... read more
October 23, 2019
Reduced food intake helps both animals and humans to improve health in old age and can prolong life. But when do you have to change your diet to achieve this benefit in old age? Scientists have now shown that mice only become healthier if they start food reduction early and eat less before entering old age. The scientists conclude that healthy behavior must be established earlier in life in order to improve health in old age and extend lifespan.

Limiting mealtimes may increase your motivation for exercise ... read more
October 19, 2019
Limiting access to food in mice increases levels of the hormone, ghrelin, which may also increase motivation to exercise, according to a new study.

Evidence of behavioral, biological similarities between compulsive overeating and addiction ... read more
October 17, 2019
Does yo-yo dieting drive compulsive eating? There may be a connection. According to researchers the chronic cyclic pattern of overeating followed by undereating, reduces the brain's ability to feel reward and may drive compulsive eating. This finding suggests that future research into treatment of compulsive eating behavior should focus on rebalancing the mesolimbic dopamine system -- the part of the brain responsible for feeling reward or pleasure.

October 17, 2019
Not all fats are equal in how they affect our skin, according to a new study. The investigators found that different ketogenic diets impacted skin inflammation differently in psoriasiform-like skin inflammation in mice. Ketogenic diets heavy in medium-chain triglycerides (MCTs) such as coconut, especially in combination with omega-3 fatty acids from fish oil and plant sources like nuts and seeds, exacerbated psoriasis.

Numerous diseases are related to disorders in the fat metabolism, such as obesity or cancer. Researchers are now demonstrating how the fat metabolism can be monitored down to the individual liver cell of a mouse with the greatest sensitivity.

Now, a study finds that young adults in the United States who are food insecure not only are slightly more likely to be obese, they are significantly more likely to suffer from disorders associated with high body mass index, as well as obstructive airway diseases like asthma.

High-fructose and high-fat diet damages liver mitochondria ... read more
October 1, 2019
High levels of fructose in the diet inhibit the liver's ability to properly metabolize fat. This effect is specific to fructose. Indeed, equally high levels of glucose in the diet actually improve the fat-burning function of the liver.

Researchers discover new, treatable pathway known to cause hypertension in obese people ... read more
September 26, 2019
There's no question that as body weight increases, so too does blood pressure. Now, in a study of mice, researchers have revealed exactly which molecules are likely responsible for the link between obesity and blood pressure. Blocking one of these molecules -- a signaling channel that's found in a tiny organ on the side of your neck -- effectively lowers blood pressure in obese mice.
