It can be concluded that physical activity may be effective in reducing burn-out risk .
The few observational studies linking sedentary and dietary behavior with burn-out risk suggest that being more sedentary and eating less healthy are each associated with higher burn-out risk .
Although it is believed that physical activity , sedentary , and dietary behavior ( i.e. , energy balance-related behavior ) may decrease the risk of burn-out  , the association between both is currently not well understood .
Therefore , the aim of this systematic review was to synthesize studies investigating the relationship between energy balance-related behavior  and  burn-out risk .
Cognitive performance is associated with glucose regulation in healthy elderly persons and can be enhanced with glucose and dietary carbohydrates.
BACKGROUND A glucose drink has been shown to improve memory in persons with poor glucose regulation and poor cognition . OBJECTIVE The objective of this study was to determine 1 ) whether an association between cognition and glucose regulation is apparent in healthy seniors and 2 ) the effects of dietary carbohydrates on cognition . DESIGN After an overnight fast , 10 men and 10 women ( aged 60 - 82 y ) consumed 50 g carbohydrate as glucose , potatoes , or barley or a placebo on 4 separate mornings . Cognitive tests were administered 15 , 60 , and 105 min after ingestion of the carbohydrate .  Plasma glucose and serum insulin were measured . RESULTS In a multiple regression analysis , poor baseline ( placebo )  verbal declarative memory ( immediate and 20-min delayed paragraph recall and word list recall ) and visuomotor task performance were predicted by poor beta cell function , high incremental area under the glucose curve , low insulin resistance , and low body mass index . The difference in plasma glucose after food consumption [ glucose > potatoes > barley > placebo ( P : < 0.03 ) ] did not predict performance . Although overall performance did not differ with consumption of the different test foods , baseline score and beta cell function correlated with improvements in immediate and delayed paragraph recall for all 3 carbohydrates ( compared with placebo ) ; the poorer the baseline memory or beta cell function , the greater the improvement ( correlation between beta cell function and improvement in delayed paragraph recall : r > -0.50 , P : < 0.03 ) . Poor beta cell function correlated with improvement for all carbohydrates in visuomotor task performance but not on an attention task . CONCLUSIONS Glucose regulation was associated with cognitive performance in elderly subjects with normal glucose tolerance . Dietary carbohydrates ( potatoes and barley ) enhanced cognition in subjects with poor memories or beta cell function independently of plasma glucose
