Workout Wednesday: How Do Sleepless Nights Effect Weight Loss?

Workout Wednesday:  How Do Sleepless Nights Effect Weight Loss?

by Danielle Gallagher

A year ago

If you’ve been having a hard time losing weight post-partum, you can probably blame your baby. One of the biggest obstacles to losing weight is a lack of sleep. And if you have a baby, your little one is probably the only thing keeping you up at 1 am…and 3 am…and 4 am. So how exactly does sleep affect weight loss?

  1. Your decision-making skills suffer

When you’re tired, the front lobe of the brain slows down. The front lobe is the part that controls decision-making and impulses. So, instead of thinking clearly and deciding to go for a jog, you end up binging on potato chips. Or you forget your sneakers when you go to the gym.

  1. The reward center of your brain amps up

This is like a double whammy. You make poor decisions, and you want to reward yourself more than usual. If you walk a block, you might feel the urge to eat five giant cookies. And if you handled a screaming baby all day, you might reward yourself with a five course meal. Sure, you deserve it, but this makes it almost impossible to lose weight.

  1. Hormones

Leptin is a hormone that tells you to stop eating. But when you don’t sleep, your leptin levels drop drastically. When you eat, it’s hard to stop. Another hormone is cortisol, and no sleep increases your cortisol. Cortisol makes your body save energy (aka fat) for a later time. So those trips to the gym might not be as effective.

  1. Being up more means you snack more

Lastly, and this one is pretty obvious, being up more means you eat more. Having breakfast at 4 am means you might eat lunch at 7 am, then dinner at 11 am. Being up at 3 am, you might be tempted to snack on donut holes. Being up all day and night means you eat all day and night.

Unfortunately, there’s not much you can do to fight the effects of no sleep, other than to sleep. And that’s not an option with a baby who sleeps… like a baby (in the real spirit of the expression, not what people with babies say). The best thing you can do is to be aware of your choices. Think carefully before you scarf down that pint of ice cream. Are you actually hungry? Be aware, and if you can, find a way to get some sleep!
