I have suffered from chronic insomnia for many years. Unfortunately, I have trouble falling asleep and staying asleep. I first became aware of the effects of poor sleep and weight gain as well as weight loss several years ago. However, now I have finally decided to take action to help my weight loss journey. So here is everything you need to know about sleep and weight loss.
I am probably more of an expert on lack of sleep or poor sleep and weight gain. For years I survived on approximately five hours of sleep on weekdays. But around 3:00 pm I needed a pick-me-up. I found energy in chips, chocolate bar, or quite frankly, any other type to junk food.
When I had trouble falling asleep, another one of my crazy habits was to eat in the wee hours of the morning. And again, I was eating junk food.
My insomnia directly added about 400-500 calories a day! And probably about 40 – 50 pounds a year! Needless to say, sleep is one of the factors of my weight gain, difficulty maintaining a healthy weight and losing weight.
The research supports my experience. When you are sleep deprived your tired brain craves junk food and your tired brain has little control to resist.
My insomnia also made it very difficult to exercise because quite simply I was too tired. Exercising before work was near impossible since I could barely get myself awake in time to go to work. Then as the day progressed, I became more and more fatigued thus there was no energy to exercise after work.
When I became my own diet coach, I knew that I had to tackle sleep in addition to diet and exercise. I did the research and put together everything you need to know about sleep and weight loss.
A good night’s sleep is important for many different reasons, including weight gain and weight loss. There are three important hormones that are affected by a lack of sleep and could lead to weight gain and affect weight loss. They are ghrelin, leptin, and insulin.
Ghrelin is sometimes called the hunger hormone. This is the hormone, released in the stomach, that tells your brain that you are hungry. This hormone increases your appetite, makes you want to eat, and store fat.
You know those times when you are so hungry that you can eat a whole cow? Probably your ghrelin levels are high. Conversely, your ghrelin levels are low when you are not hungry.
Research has shown that poor sleep causes your ghrelin levels to increase which of course causes hunger and weight gain. The first thing you need to know about sleep and weight loss is that getting more sleep will help you to feel less hungry and lose weight.
There are a couple of other ways to keep your ghrelin levels low: eating more protein and gaining more muscle.
Leptin is the second hormone that is affected by sleep. It is also sometimes called the starvation or hunger hormone. Leptin, released from fat cells, tells your brain that it is full and suppresses hunger. Leptin also affects how you burn calories. When you are full you burn calories normally, but when your leptin levels are low you burn calories more slowly.
Many studies have found that poor sleep lowers our leptin levels and function. The second thing you need to know about sleep and weight loss is that getting more sleep will help you to feel full and avoid hunger. Also, you avoid lowering your metabolism.
If you wonder how else can you control your leptin levels, you can try eating more fish, fiber, exercise, and avoiding foods and drinks high in sugar.
You may have seen leptin supplements, but don’t waste your money since there is little research to show that these supplements are effective.
Insulin is another hormone that is affected by sleep. Insulin moves sugar through the bloodstream to be used as energy. But when we become insulin resistant we store the sugar which eventually causes our bodies to make more insulin, we get hungrier and store more calories as fat.
Insulin resistance is commonly known to cause diabetes. However, some studies have found that just a few nights of poor sleep can cause insulin resistance and weight gain.
Getting a good night’s sleep will help to keep your insulin level low and this is the third thing you need to know about sleep and weight loss.
There are a number of foods to avoid to keep your insulin level low. They include:
- Sweetened drinks
- Processed foods
- Sugary sweets
- Refined grains
- Flour based foods
- Fried foods
- Foods high in saturated fat
Low insulin foods include:
- Lean meats
- Dark leafy vegetables
- Sweet potato
- Yogurt (unsweetened)
