Does Sleep Affect Your Metabolism and Weight?

Hormone imbalances can cause weight problems. Too much glucose, for example, will cause insulin spikes which in turn halts fat loss. Excessive estrogen in Women has also been shown to inflict weight control problems. In fact, balance in the human endocrine system is a key component to weight control and some successful diet programs such as the Zone capitalize on this well documented detail.

However, our hormone processes are far from simple and keeping them under control is not necessarily easy. But there are some things we can do to energize our endocrine, including getting our required sleep.

What many people don’t realize is that sleep is incredibly important – not only so we don’t feel awful in the morning, but also because a lack of sleep disrupts the effectiveness of our metabolic processes which could lead to weight control issues (amont other things).

Studies have found that glucose tolerance and carbohydrate metabolism ability is lower in sleep-debt conditions (those restricted to around 4-5 hours of sleep per night) relative to fully rested conditions.

Another recent study, done over 5 years, found that having less than 5 hours of sleep per night was related to a higher BMI compared to sleep durations of between 6 and 7 hours.

I’ve mentioned this in many previous posts – that sleep is critical to health, weight control and muscle growth. Get those 7 hours of sleep and if possible don’t feel bad about sleeping in even more over the weekend ;)
