Caffeine, coffee, and appetite control: a review

Abstract: Coffee and caffeine consumption has global popularity. However, evidence for the potential of these dietary constituents to influence energy intake, gut physiology, and appetite perceptions remains unclear. The purpose of this review was to examine the evidence regarding coffee and caffeine's influence on energy intake and appetite control. The literature was examined for studies that assessed the effects of caffeine and coffee on energy intake, gastric emptying, appetite-related hormones, and perceptual measu… Show more

“…Few studies have investigated the influence of coffee consumption on energy intake. The studies that exist somewhat contradict our finding, with coffee consumption either having no effect on single meal energy intake or leading to a small daily decrease in energy intake [ 32 ].…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Caffeine has been shown to positively enhance mood state, energy, creative problem-solving, and motivation 23,24 . Caffeine and capsaicinoids may both suppress appetite through neurotransmitter and catecholamine release (i.e., increased dopamine, norepinephrine, and serotonin levels) 25,26 and inhibition of appetite stimulating signals (i.e., ghrelin) 27 ; however, this investigation observed appetite suppression in both groups similarly. Alternatively, no changes were observed in fatigue within or between groups.…”

“…However, the effects of caffeine at physiological concentrations (like the low dosages provided herein) in vivo are instead likely due to adenosine receptor antagonism [87]. Further, caffeine may also stimulate a reduction in food consumption in both mouse [90] and human [91] models. However, there are also reports indicating caffeine can also increase food consumption in various mouse models [92,93].…”
