2. Insomnia or Sleeplessness

The second reason why you may not be losing the fat you had hoped you would is if you aren’t sleeping enough at night. Getting sufficient sleep is imperative to success because not only does sleep have an influence on your metabolic rate, but it’s also going to help to boost insulin sensitivity and help you control your hunger level better throughout the day as well.
Sleeping enough is vital to progress, so make a date with your bed to get 8 hours in and don’t miss it.
Sleep is also when you recover best from each workout session you do, so if you’re lacking in sleep, don’t be surprised if your gym performance starts suffering.
