Suppresses appetite.

Question 2

After poor sleep, you’re more likely to have serious fatigue and brain fog. Your system, desperate for a shot of energy, triggers cravings for sugar carbs, even if you’re not actually hungry. Aim for 7 to 8 hours of sleep a night, and you’ll get your energy level and hunger hormones back on track.

Answer 2

You're a stress case
Who hasn't dealt with a high-pressure workday or relationship rough spot by giving into cravings for a pint of Rocky Road? But stress has a sneakier way of making you voracious. When you're tense, your system ramps up production of the stress hormones adrenaline and cortisol, says Rumsey. Elevated levels of these hormones trick your system into thinking it's under attack and needs energy, so your appetite starts raging. Stress also reduces levels of the brain chemical serotonin, and that can make you feel hungry when you aren't, says Moon. Consider it a case for making it to yoga class more often, or cranking up a soothing playlist on your commute home.
