Sleep More, Lose Weight

Sounds crazy, but it is true for a lot of people.

A few months ago, Jessica came to see me with concerns that she had a metabolism problem. She was understandably frustrated and overwhelmed. She has two small children and is battling the last remaining extra pounds from her pregnancies. While caring for two small children is a full time job, her new goal is to refocus on taking care of herself a little bit too.

She never had a terrible diet, but is now diligent about eating healthy foods and mixing in more fruits and vegetables. She actually started exercising again. She wakes up at 5:00 a.m. to work-out while her husband is still home and her kids are sleeping. So, why isn’t she losing any weight? Before, she wasn’t exercising or watching her diet. Now that she has made lifestyle changes, nothing has happened!

After running through a number of questions, I learned that Jessica goes to bed at midnight. She explains that her house is finally quiet after her children are asleep and she is able to get organized for the next day. So, she takes a few hours to unwind with her husband and perhaps watch some TV. But going to bed at midnight means she is getting only five hours of sleep every night – and that simply is not enough.

How can sleeping too little promote weight gain?

Studies have shown that sleep is in fact related to weight. There are several hormones that are produced while you sleep, such as ghrelin and leptin, that regulate weight and appetite control. These hormones are not produced properly with less than seven hours of sleep.

What happens when we are sleep deprived?

Research has also shown that people who are sleep deprived tend to crave higher calorie foods. Additionally, if you are tired, you are less motivated to exercise and make the effort it takes to eat a healthy diet.

What is enough sleep?

Like many things, optimal sleep time is an individual thing. It is not uncommon for women to require 7-9 solid hours of sleep to be well rested. This is a bit more than their male counterparts. However, there are exceptions to this. A small percentage of women (and men) require much less sleep. These people tend to know who they are. Famous examples include Bill Clinton and Martha Stewart.

Is all sleep created equal?

Not quite. There is the issue of quality of sleep. Even if Jessica were going to bed at 9:00, if her eight hours of sleep a night are interrupted hours or not “good sleep,” she may have the same problem. The reasons for poor sleep may include snoring, restless legs and other sleep disturbances (both medical causes and external ones. Say….children). If you suspect that you are getting a sufficient amount of sleep but are still tired, your sleep quality may not be adequate. You should make sure to be evaluated by your doctor.

Certain sleep disorders can in fact be related to vitamin deficiencies, too! A 2024 study found that female participants with iron and Vitamin D deficiencies were more likely to have poor sleep quality. Vitamin D is heavily involved in the regulation of sleep and melatonin levels, and iron is a key component of dopamine regulation, an important neurotransmitter in our sleep-wake cycles. If your diet lacks other vitamins–like Vitamin B12 and Vitamin C–you might also struggle to keep your sleep schedule on track. Having a multivitamin personalized to your needs might be the boost you need to catch those extra Z’s! We could go on and on about the benefits of vitamins for sleep, but more on that in a future post.

What happened to my patient?

In Jessica’s case, she slept just fine once she went to bed. She simply was not getting enough of it. Jessica finally got to sleep! Six months later, her lifestyle changes and her new sleep schedule finally paid off. She reached her goal weight and found that she had more energy for her family.
