The Facts:
* 80 overweight or obese people took part in a study to investigate whether a dietary supplement containing tyrosine, capsaicin, catechines and caffeine increased their ability to burn fat.
* After 8 weeks, people who were taking the supplement in addition to reducing calorie intake burned fat at a greater rate than those who were on a reduced calorie diet alone.
* Body fat mass was reduced in the group taking the supplement by almost 1kg and no effect was seen on heart rate or blood pressure.
Shaun’s comment: We know that exercise can burn off fat, but in this study the idea was to burn off fat by using a combination of natural products such as caffeine that increase your heart rate and metabolism. It also seemed to work, with around an extra kilo being lost in the group who took the supplement. However, I would not recommend that this supplement combination was taken long-term as I would be worried about the effects on the heart and blood pressure.
