The nonfat part of the body termed as lean body mass. Technically, it’s the amount of weight on the body which is considered as nonfat. Lean body mass is an important consideration as its weight must be relatively constant. So, if you’re aiming a body shape or weight especially if you’re an athlete, body builder, etc. your lean body mass should not change rather you burn or reduce your body fat percentage.
Insomnia is defined as the inability to fall asleep, remain asleep, or get the amount of sleep an individual needs to wake up feeling rested. Its symptoms include difficulty falling asleep, frequent wake-ups during the night, waking up too early in the morning, daytime sleepiness, difficulty concentrating, and irritability. Insomnia can be acute (lasting one to several nights) or chronic (lasting from a month to years). It’s also the most common sleep complaint among Americans (especially women).
