In this study, the authors examined the effects of capsaicin, green tea and CH-19 sweet pepper on energy intake and appetite of healthy individuals during states of negative and positive energy balance in the body. During a state of positive energy balance, the bioactive ingredients led to reduction in energy intake when used in combination. The authors concluded that bioactive ingredients like capsaicin and green tea can help in reducing energy intake and may be useful in weight reduction periods.
In recent times, bioactive substances like green tea and capsaicin have been recognized as beneficial due to their role in satiety, energy metabolism, and substrate oxidation. However, their effect on other parameters, such as appetite and energy intake, remains unexplored. “Increased activity of the sympathetic nervous system (SNS) after ingestion of capsaicin suggests that the reduction in energy intake could be due to the anorectic effect of catecholamines.” The authors studied the effect of capsaicin, green tea, CH-19 sweet pepper, and their combination on appetite and energy intake for finding a relationship between the consumption of these bioactive ingredients and appetite and energy consumption. The purpose was to explore a basis for efficient weight reduction plans.
* The study was conducted on 27 healthy young persons aged between 20 and 32 years.
* Over a six-week period, the subjects were observed under conditions of positive and negative energy states.
* During positive energy states, the subjects were given heavy breakfasts and lunches and during negative energy states they were given light breakfasts and lunches.
* The subjects were also given bioactive ingredients like capsaicin, green tea, CH-19 sweet pepper, a combination of capsaicin and green tea, or a placebo.
* The authors measured the appetite hunger, desire to eat, prospective food consumption, fullness, and satiety of the participants during study.
* CH-19 sweet pepper and a combination of capsaicin and green tea led to decrease in energy intake during a state of positive energy balance.
* The suppression of hunger by capsaicin and green tea was higher during the state of negative energy balance than during positive energy balance.
* A combination of capsaicin and green tea lowered the desire to eat fatty, salty, hot or bitter food.
This study could not confirm the effect of positive or negative energy balance on treatment effects of bioactive ingredients. More such bioactive ingredient combinations need to be tested for their ability to reduce appetite and promote satiety. Practical ways to introduce these measures into daily life need to be explored so that effective weight reduction strategies can be devised.
The study found that bioactive ingredients like capsaicin, green tea, and CH-19 sweet pepper are useful in promoting satiety and decreasing energy intake in healthy individuals. The best results were seen when capsaicin and green tea were used in combination and the subjects were in a state of negative energy balance. Capsaicin, green tea and their combination led to a decreased desire to take fatty, salty and hot foods. Capsaicin was helpful in lowering desire for sour foods as well. The combination of capsaicin with green tea was useful in reducing the desire for bitter foods. Such combinations of bioactive ingredients can be used to reduce energy intake and be incorporated into weight reduction plans.
