Best supplements for weight loss: Taking fibre or caffeine pills to increase fat burning


There are some studies indicating that caffeine supplements could have a modest effect on weight loss.

In a study published in the American Journal of Physiology, the effects of caffeine ingestion on fat oxidation and energy expenditure in younger and older men was analysed.

The study said: “Age-related differences in energy expenditure, fat oxidation, and norepinephrine (NE) kinetics after caffeine ingestion were examined using a placebo-controlled double-blind study in 10 older and 10 younger men who were moderate consumers of caffeine.

“Rates of fat oxidation and NE appearance and clearance did not significantly differ from baseline values in either group.

“In conclusion, older and younger men show a similar thermogenic response to caffeine ingestion, whereas older men show a smaller increase in fatty acid availability after a caffeine challenge.

“These metabolic differences are not related to alterations in NE kinetics or fat oxidation.”
