"Ingredients for obesity management are tea, caffeine and capsaicin, as they increase daily [energy expenditure] with 4–5% [roughly 70 to 100 calories] without increasing energy intake and counteract the decrease in metabolic rate during weight loss," a recent paper concludes.
"Studies have shown that these ingredients are useful in losing weight or preventing weight regain after weight loss." Paper’s Conclusion
The paper’s entire conclusion
“Ingredients for obesity management, including caffeine, capsaicin and different teas such as green, white and Oolong Tea, have been proposed as strategies for weight loss and [weight maintenance], as they may increase EE (4–5%), fat oxidation (10–16%) and have been proposed to counteract the decrease in metabolic rate that is present during weight loss,” the paper notes.
“Daily increases in thermogenesis of approximately [70-100 calories] can eventually lead to substantial weight loss.
“However, it becomes clearer that certain conditions have to be met before thermogenic ingredients yield an effect, as intra-variability with respect to body weight regulation has been shown between subjects.
“Taken together, these functional ingredients have the potential to produce significant effects on metabolic targets such as satiety, thermogenesis and fat oxidation.
“A significant clinical outcome sometimes may appear straightforwardly but also depends very strongly on full compliance of subjects.
“Nevertheless, thermogenic ingredients may be considered as functional agents that could help in preventing a positive energy balance and obesity.”
