A new study at the Weill Cornell Medical College in Qatar has revealed that losing as little as half an hours sleep every day could cause weight gain.
With weight gain comes an increased risk of developing numerous health conditions such as heart disease and type 2 diabetes so you need to take research such as this seriously.
What did the study involve?
The team of researchers recruited 522 volunteers who had recently been diagnosed with type 2 diabetes.
These volunteers were then split into 3 groups; usual care, physical activity intervention, or diet and physical activity intervention.
Each participant was asked to complete a 7-day sleep diary and were also asked to calculate their weekday sleep debt.
What were the results of the study?
The results of the study showed that those who had a weekday sleep debt were 72% more likely to be obese, with every 30 minutes of sleep debt resulting in an increase in obesity (17%) and insulin resistance (39%).
Previous studies have shown that a lack of sleep is a contributing factor in weight gain, with this latest study showing that as little as 30 minutes can make such a huge difference.
Lead study author Shahrad Taheri had this to say about the results:
“This reinforces earlier observations that sleep loss is additive and can have metabolic consequences.”
“While previous studies have shown that short sleep duration is associated with obesity and diabetes, we found that as little as 30 minutes a day sleep debt can have significant effects on obesity and insulin resistance at follow up.”
So what can we do?
Basically if you want to reduce your risk of weight gain you need to make sure you are getting a good nights sleep.
This latest study has shown that 30 minutes less each night can cause big problems.
A lack of sleep can cause an increase in cortisol production, which can lead to food cravings.
Get a minimum of 7 hours sleep a night and move one little step closer to losing weight. Of course diet and exercise would help too.
