In another study that followed about 70.000 women for 16 years, there was a significant increase in body weight in those who slept 5 hours or less compared to those who slept 7–8 hours. [1] [2] [8] As sleep time decreased over time from the 1950s to 2000s from about 8.5 hours to 6.5 hours, there has been an increase in the prevalence of ...
Sleep restriction in normal-weight subjects also showed an increase in activity of reward and food-sensitive areas of the brain when viewing unhealthy food, compared with viewing healthy food. [26] [27] This study shows a link between restricted sleep and susceptibility to food stimuli, which might increase the risk of overeating. [26]
Older adults, particularly those with acute or chronic illnesses, may require higher protein intake, ranging from 1.2 to 1.5g/kg per day, due to a reduced anabolic response. Some studies suggest that an intake of 1 g/kg per day is sufficient, while others recommend 1.3 to 1.73g/kg per day for better health outcomes.

Replacing red meat with plant-based protein sources such as nuts and legumes was associated with a 19% lower risk of dementia and 1.37 fewer years of cognitive aging, according to the study.
Within a few months of postnatal development, there is a marked reduction in percentage of hours spent in REM sleep. By the time the child becomes an adult, he spends about 6–7 hours in NREM sleep and only about an hour in REM sleep. [46] [47] This is true not only of humans, but of many animals dependent on their parents for food. [48]
A 2004 editorial in the journal Sleep stated that, according to the available data, the average number of hours of sleep in a 24-hour period has not changed significantly in recent decades among adults. Furthermore, the editorial suggests that there is a range of normal sleep time required by healthy adults, and many indicators used to suggest ...
