The management of overweight may include the use of dietary supplements targeted to counter the feeling of hunger. A randomized, double-blind, placebo-controlled trial has been performed in 20 overweight females. These subjects were randomly assigned to supplement their diet with either an extract from Griffonia Simplicifolia (10 subjects) or a placebo (10 matched subjects) for 4-weeks, in conjunction with a personalised reduced calorie diet. The main aim of this study was to evaluate the… Expand
Appetite-Suppressing and Satiety-Increasing Bioactive Phytochemicals: A Systematic Review
TLDR
Assessment of the most commonly used bioactive phytochemicals with appetite/hunger-suppressing and/or satiety/fullness-increasing properties revealed mostly inconclusive evidence that the tested phytochemical complementary remedies are effective in suppressing appetite/Hunger and/ or increasing satiety-fullness.

Natural anti-obesity agents and their therapeutic role in management of obesity: A future trend perspective.
TLDR
A metanalysis of all the available data on the use of the plants with their biological source, active phytochemical constituents and a probable mechanism of action as natural anti-obesity agents reveals the need and scope of further research in the development of new natural phytoconstituents for the management of obesity.

Satiety and amino-acid profile in overweight women after a new treatment using a natural plant extract sublingual spray formulation
TLDR
5HTP-Nat Exts may be safely used to treat the problem of appetite control in overweight women during a weight loss program, and all the amino acids evaluated after a single administration were found to be similar. Expand
The effects of oral 5-hydroxytryptophan administration on feeding behavior in obese adult female subjects
TLDR
The administration of 5-hydroxytryptophan resulted in no changes in mood state but promoted typical anorexiarelated symptoms, decreased food intake and weight loss during the period of observation. Expand
Eating behavior and adherence to dietary prescriptions in obese adult subjects treated with 5-hydroxytryptophan.
TLDR
Significant weight loss was observed in 5-HTP-treated patients during both periods and a reduction in carbohydrate intake and a consistent presence of early satiety were found, suggesting that 5- HTP may be safely used to treat obesity. Expand
The effect of a nutritional source of tryptophan on dieting-induced changes in brain 5-HT function
TLDR
While TRP treatment did not increase fasting TRP availability it may have modified the effect of dieting on brain 5-HT function, and further studies will be needed to see if this effect of TRP has consequences for the effectiveness of diets as means of weight control. Expand
Lipid metabolism in trained rats: effect of guarana (Paullinia cupana Mart.) supplementation.
TLDR
The results show an effect of guarana on aspects of lipid metabolism, which is abolished by decaffeination, and the changes in lipid metabolism of supplemented rats herein reported are associated with the methylxanthine content of Guarana. Expand
Effects of oral 5-hydroxy-tryptophan on energy intake and macronutrient selection in non-insulin dependent diabetic patients
TLDR
Data confirm the role of the serotonergic system in reducing energy intake, by predominantly inhibiting carbohydrate intake, and suggest that 5-HTP may be safely utilized to improve the compliance to dietary prescriptions in non-insulin dependent diabetes mellitus. Expand
The anorectic effect of increasing doses of L-tryptophan in obese patients
TLDR
The results provide support for the view that serotoninergic mechanisms play a role in the regulation of human food intake and are consistent with the hypothesis that nutrients which increase 5-HT availability selectively alter carbohydrate consumption. Expand
Serotonin a la carte: supplementation with the serotonin precursor 5-hydroxytryptophan.
TLDR
Preclinical and clinical evidence for the efficacy of 5-HTP for depression is reviewed, with emphasis on double-blind, placebo-controlled (DB-PC) trials, and safety issues with 5- HTP are reviewed,With emphasis on eosinophilia myalgia syndrome (EMS) and serotonin syndrome. Expand

TLDR
Neither food selection nor basal plasma amino acid profiles were predictors of weight loss during long-term treatment with dF as an adjuvant to energy restriction, and they were not affected by the drug treatment. Expand
The Effects of Dieting on Plasma Tryptophan Concentration and Food Intake in Healthy Women 1 1 Presented in part at the 7th International Conference on Eating Disorders, April, 1996.
TLDR
The observed decreases in plasma TRP and TRP: sigma BCAA extend previous reports suggesting that dieting behavior may diminish central serotonin function through a reduction in precursor availability. Expand
