“Coffee also contains chlorogenic acid, which helps to slow down the absorption of carbohydrates and supresses our hunger hormone, Ghrelin. This hormone is stimulated by carbohydrates, which sits in our stomach and growling at us to feed it more and more.
“Carbohydrates also shut off our leptin response – this is the hormone that tells our brain when we are full. By supressing ghrelin and stimulating leptin, we can effectively reduce our appetite.
“It is also interesting to note that decaffeinated coffee still contains the important Chlorogenic Acid, and therefore could still produce an appetite supressing effect.
“A word of caution though to coffee lovers who are partial to more than a simple cup of black coffee. Some coffees, such as milky lattes and cappuccinos, can contain a huge number of calories and sugars, all of which can contribute to weight gain, as well as increasing our insulin and ghrelin levels.
:If you are opting for coffee to help lose weight, choose a simple black coffee or one with a dash of milk and avoid sugar and drinks laden with syrup and lots of milk.”
