    BACKGROUND & AIMS: Bioactive ingredients have been shown to reduce appetite and energy intake. The magnitude of these effects might depend on energy balance why it was investigated how capsaicin, green tea, CH-19 sweet pepper as well as green tea and capsaicin affect appetite and energy intake during respectively negative and positive energy balance. METHODS: 27 subjects were randomized to three weeks of negative and three weeks of positive energy balance during which capsaicin, green tea, CH-19 sweet pepper, capsaicin+green tea or placebo was ingested on ten separate test days while the effects on appetite, energy intake, body weight and heart rate were assessed. RESULTS: CH-19 sweet pepper and a combination of capsaicin and green tea reduced energy intake during positive energy balance. Capsaicin and green tea suppressed hunger and increased satiety more during negative than during positive energy balance. CONCLUSIONS: Bioactive ingredients had energy intake reducing effects when used in combinations and in positive energy balance. Energy balance did not affect possible treatment induced energy intake, but did affect appetite by supporting negative energy balance. Bioactive ingredients may therefore be helpful in reducing energy intake and might support weight loss periods by relatively sustaining satiety and suppressing hunger.
