Umami and appetite: effects of monosodium glutamate on hunger and food intake in human subjects.
In view of a dramatic increase in the incidence of obesity, the present study examined the appetite effects of a functional fiber as a potential dietary intervention.
Controlling for appetite effects is less straightforward although the observed profile of effects does not necessarily correspond with the drugs' known effects on appetite (Stuart et al., 2013).
Although little is known in the medical literature about the anti-appetite effect of the above cited substances, we can make the hypothesis that the weight gain following smoking cessation could be a 'rebound effect' of discontinuation of the daily consumption of an anti-appetite substance through cigarette smoking, as it is known for the use of other anti-appetite substances.
Tobacco industry investigated additional substances for their anti-appetite effects, but they were not found in cigarette ingredients lists: 'Ephedrine and amphetamine', two well-known sympathico-mimetic appetite suppressants, were considered as cigarette ingredients in the 1960s.
Conclusion: These tobacco companies played an active and not disclaimed role in the anti-appetite effects of smoking, at least in the past, by adding appetite-suppressant molecules into their cigarettes.
Considering any potential interpretation of our effects in terms of an appetite enhancing effect immediately leads to a comparison of the active dose range in the light phase food intake and in the cancer cachexia model.
Psychoactive effects last 4 to 6 hours but the appetite stimulant effect may continue for 24 hours [ 22].
Ghrelin and cannabinoids stimulate appetite, this effect possibly being mediated by the activation of hypothalamic AMP-activated protein kinase (AMPK), a key enzyme in appetite and metabolism regulation.
Furthermore, the appetite stimulatory effect of another MC4R antagonist, JKC-363, has previously been shown to be attenuated by CB1 receptor blockade [22].
The appetite suppressant effect of naloxone is centrally mediated, resulting from neuronal interactions in the reward pathway.
