High-fat diets might not be best for weight loss, one study shows

If you’ve gone on a diet recently, you’ve probably been told by a friend or even a fitness professional that a low-carb, high-fat diet is the fastest way to fitness. The theory goes that this type of diet will force your body into ketosis, where it will burn fat instead of carbs, prompting you to shed more pounds. But a new study suggests that this might not be the case. The new study from the University of Aberdeen in the Chinese Academy of Sciences was published in Cell Metabolism. Researchers found that mice who ate high-fat diets gained more weight over a three-month period than mice who ate high-carb diets. And actually, the mice fed carbs, didn’t gain any weight at all, while the high-fat diet produced overweight mice. Researchers at Aberdeen studied how mice responded to 30 different diets, which varied widely in fat and carb content. The diet-appropriate foods…

Smelling food can make you fat, new study shows

Your nose might be sabotaging your weight loss efforts. New research has revealed that simply smelling food can make you pack on the pounds. Yikes! The study, conducted by UC Berkeley researchers and published in Cell Metabolism, used three groups of mice — a set of “super-smellers,” a group whose smell was temporarily disabled, and a control group. The mice ate the same amount of a “Burger King diet.” When the mice weighed in at the end of the study, those with the impaired sense of smell gained the least weight — a mere 10 percent of their body weight, while the “super smellers” gained the most weight — nearly doubling in size. The findings show that your olfactory system affects your appetite as well as your metabolism. The normal mice, of course, ballooned in size too. “In the context of food and appetite, this is really novel,” lead study author Celine Riera told SF Gate. However,…
