Capsaicin keeps metabolic rate high during weight loss diet
You can probably speed up a weight loss diet a little by consuming a gram of chilli powder at meals. According to a human study that Dutch nutritionists published in PLoS One, a supplement containing capsaicin - the most active substance in chilli powder - prevents your metabolism from slowing down if you've reduced your calorie intake.
Capsaicin
Study
The subjects were given 1.03 g chilli powder - which contained 2.56 mg capsaicin - at each meal. Not everyone reacts well to this fairly high quantity, so the researchers selected subjects who were used to eating chilli pepper regularly.
On one occasion the subjects consumed 100 percent of the amount of energy they expended, and took no capsaicin. On another occasion the subjects consumed the same amount of energy, but took capsaicin at each main meal.
On a third occasion the subjects consumed 75 percent of the amount of energy they expended, and took no capsaicin. And on yet another occasion the subjects consumed the same amount of energy, but took capsaicin at each main meal.
Results
When the subjects consumed 75 percent of their calorie requirements and did not take capsaicin, they did not start to burn significantly more fat according to the researchers' statistical calculations.
When the subjects took capsaicin at meals there was a statistically significant increase in fat burning.
Blood pressure
Conclusion
"Moreover, consumption of 2.56 mg capsaicin per meal promotes fat oxidation in negative energy balance and does not increase blood pressure significantly."
