For people who stay up late and fewer hours sleeping, this could be impacting your ability to lose weight. From an evolutionary perspective, your body will store more body fat during the summer months. Getting less hours of sleep tells your body that it is summer, which means the hormones are eternally trying to store body fat for the winter. Your body has programmed over millions of years to produce this response and the reality of the season will not change anything.
If you want to assist in your weight loss goals, try to get at least 9.5 hours of sleep every day. For many busy people it might sound like a lot, but getting your hormones back into balance is well worth the time. Plus, you’ll feel even more rested and alert at work!
