Stress and Weight: What's Really Going On
Forget the "cortisol belly" ads. Stress mainly affects your weight through food, sleep and habits, and those are things you can work with.
The short version
- Long-term stress can affect appetite, sleep and activity, all of which affect weight.
- Cortisol plays a part, but "cortisol belly" supplements and detox programs aren't evidence-based.
- Simple practices like walking, slow breathing and talking to people can reduce stress quickly.
- If stress feels unmanageable, you deserve support. Call or text 988 in a crisis.
How stress affects your weight
- Appetite. Short-term stress can kill your appetite. Longer-term stress often raises it, especially for sugary, fatty foods.
- Sleep. Stress can disrupt your sleep, and poor sleep brings on its own hunger.
- Less activity. Your workout is often the first thing to go.
- Less planning. You've got no bandwidth for cooking, so takeout and snacks take over.
- Hormones. Long-term stress keeps cortisol elevated in some people, and this may promote fat storage around the middle.
About "cortisol belly"
You've probably seen the ads. There's a real link between stress hormones and belly fat, but it's overhyped, and the products aimed at it are unproven. If you have a very high cortisol level because of a medical condition (Cushing's syndrome), that's a real disease with specific symptoms, including rapid weight gain, a rounded face, thin skin, easy bruising and purple stretch marks, and it needs a doctor, not a supplement.
What helps
Quick relief, in 5 minutes or less
- Slow breathing. Breathe in for 4, out for 6, for a few minutes. A longer exhale can calm your body.
- Move. Walk outside for 5 or 10 minutes. It's one of the fastest ways to change your state.
- Name it. "I'm stressed about tomorrow's meeting." Simply naming it can take the edge off.
- Change location. Step away from your desk, the kitchen or your phone.
Long-term
- Regular exercise. One of the best-supported stress reducers.
- Consistent sleep.
- People. Talk with friends, family or a support group. Isolation makes almost everything worse.
- Mindfulness or meditation. Even 10 minutes a day can help some people. Apps can be a good way to start.
- Therapy. Cognitive behavioral therapy helps people work with stress and anxiety in practical ways.
- Boundaries. Sometimes the answer is reducing your load rather than coping better with it.
During very stressful periods
Your job, family or health might make this a bad time to diet hard. That's okay. A valid goal for a tough stretch is maintaining, or just keeping a few basics going:
- Eat regular meals with some protein.
- Walk a little most days.
- Protect your sleep.
Then pick back up when you can. Not every season of your life has to be a weight-loss season.
