When too much glucose enters fat cells, they stop making the proteins needed to get and build healthy fats for mitochondria
When mice with excess glucose uptake eat a very low-carb diet, their fat-burning tissue works better in the cold because the diet changes the types of fats in their mitochondria
When mice can't control how much glucose enters their cells, their fat-burning tissue doesn't work as well in the cold because the mitochondria don't have enough healthy fats in their membranes
Adding high-intensity interval training to a very low-carb diet doesn't stop the muscle loss that happens when people with excess body fat eat very few carbs for 12 weeks.
Eating very few carbs and more fats for 12 weeks doesn't improve the maximum oxygen your body can use during exercise in people with excess body fat when measured in absolute terms.
When people with excess body fat eat very few carbs and more fats, their bodies burn more fat for fuel during intense exercise, as shown by lower respiratory exchange ratio measurements.
Doing short bursts of intense exercise for 12 weeks doesn't improve the maximum oxygen your body can use during exercise in people with excess body fat, even though they can exercise longer before getting tired.
Eating very few carbs and more fats for 12 weeks makes people with excess body fat lose about 6-9 centimeters from their waist size.
When people with excess body fat eat very few carbs and more fats, their blood ketone levels rise quickly within two weeks, showing their body has switched to burning fat for fuel.
Adding high-intensity interval training to a very low-carb diet doesn't make the belly fat reduction any better than just doing the diet alone in people with excess body fat.
When people with excess body fat eat very few carbs and more fats, they lose about 4-5% of their muscle mass within a month, and this muscle loss continues for the full 12 weeks of the diet.
Doing short bursts of intense exercise a few times a week for 12 weeks makes people with excess body fat able to exercise longer before getting tired, but doesn't significantly improve their maximum oxygen capacity.
Eating very few carbs and more fats for 12 weeks makes the dangerous belly fat around organs shrink by about a quarter in people who have too much body fat.
Taking GlyNAC for 16 weeks helps older adults with obesity improve blood vessel health by reducing markers of inflammation in blood vessels, bringing them back to levels normally seen in younger people.
Taking GlyNAC for 16 weeks significantly improves insulin sensitivity in older adults with obesity, bringing it back to levels normally seen in younger people.
Taking GlyNAC for 16 weeks helps older adults with obesity reduce DNA damage in their blood and muscles, which could help protect against cellular aging and disease.
Taking GlyNAC for 16 weeks helps older adults with obesity reduce markers of cellular aging in muscles and improve muscle stem cell activity, which could help with muscle repair and maintenance.
Taking GlyNAC for 16 weeks helps older adults with obesity reduce belly fat and lower blood pressure, but doesn't significantly change overall weight or body mass index.
Taking GlyNAC for 16 weeks helps older adults with obesity walk faster and have stronger hands, bringing their physical abilities closer to those of younger people.
Taking GlyNAC for 16 weeks significantly reduces inflammation in older adults with obesity, bringing their inflammatory markers down to levels normally seen in younger people.
Taking GlyNAC for 16 weeks helps older adults with obesity burn fat more efficiently in their mitochondria and use less glucose for energy, bringing their metabolism closer to that of younger people.
Taking GlyNAC for 16 weeks significantly reduces markers of oxidative damage in older adults with obesity, bringing them down to levels normally seen in younger people.
Taking GlyNAC for 16 weeks helps older adults with obesity make more of their body's main antioxidant in muscles and blood, bringing it up to levels normally seen in younger people.
Taking GlyNAC for 16 weeks helped older adults have higher levels of glutathione, a key antioxidant, compared to before they started taking it.
