4 Sneaky Waist Inflators
Stress Cortisol (the fight-or-flight hormone released from the adrenal gland) increases blood sugar, which increases insulin, which increases the deposit of belly fat.
Sleep deprivation Being overly tired leads to higher cortisol levels (see above) and throws your appetite-regulating hormones out of whack. And that -- you know what's coming next -- can result in binge eating.
Low vitamin D A vitamin D deficiency can contribute to blood-sugar-regulation problems, insulin resistance, and, yep, tummy rolls.
Constipation If you don't keep things moving, you know where it will all sit. Get regular with high-fiber foods (broccoli, peas, pears, ground flaxseeds) and lots of water. A probiotic supplement -- which has good bacteria to aid digestive health -- will help, too.
