Fill Your Vitamin D Fix
There's a lot of research showing a connection between vitamin D deficiencies, fat cell function, and obesity, but the entire relationship between vitamin D and weight loss is still not entirely understood. Still, it's important to make sure you're getting enough. "You need vitamin D for good muscle and bone metabolism," says Dr. Kirkendol. "Your muscles aren't going to grow the way they should if they're vitamin D deficient."
Dr. Raj, however, cautions against just loading up on vitamins at the local drug store. Instead, she suggests you get checked for a vitamin D deficiency at your next check up. "If you're truly deficient, your doctor can prescribe a prescription-strength supplement," she says, adding that over-the-counter supplements are hard to trust due to their lack of regulation.
