When only fat cells lack TXNIP, they show the same mitochondrial problems as when the whole body lacks TXNIP

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
