High-glycemic-index carbohydrate meals shorten sleep onset.
It was shown that a carbohydrate-based high-GI meal resulted in a significant shortening of SOL in healthy sleepers compared with a low-GI Meal and was most effective when consumed 4 h before bedtime.
Acute effects of the very low carbohydrate diet on sleep indices
In healthy, good sleepers, the VLC diet over the short-term promotes increases in the percentage of SWS (deep sleep stage 4) and a reduction in the Percentage of REM sleep ('dreaming' sleep) compared to the control mixed diet, which may be linked to the metabolism of the fat content of the V LC diet.
The immediate effects of intravenous specific nutrients on EEG sleep.
Effects of meals on objective and subjective measures of daytime sleepiness.
The results suggest that the meals induced an enhancement in sleepiness that was not solely due to circadian rhythms.
Short Sleep Duration Is Associated with Reduced Leptin, Elevated Ghrelin, and Increased Body Mass Index
Differences in leptin and ghrelin are likely to increase appetite, possibly explaining the increased BMI observed with short sleep duration, and changes in appetite regulatory hormones with sleep curtailment may contribute to obesity.
Metabolic effects of low glycaemic index diets
The persistence of an epidemic of obesity and type 2 diabetes suggests that new nutritional strategies are needed if the epidemic is to be overcome and a promising nutritional approach is metabolic effect of low glycaemic-index diet.
BRIEF COMMUNICATION: Sleep Induced by L-Tryptophan: Effect of Dosages within the Normal Dietary Intake
The present laboratory study extends the dose-response curve downward, comparing doses of ¼ g, ½ g, and 1 g of L-tryptophan with placebo, in 15 mild insomniacs (subjects who reported sleep latencies of over 30 minutes).
