i add some fenugreek powder to the shake, it also thickens the consistency. its pretty much tasteless. and it makes you feel Full Up.
it has other health benefits too…
its cheap to buy - some places like buywholefoodsonline sell it for about £5 for 1kg
if you feel hungry after a meal, or feel hungry not long after a meal it reduces your appetite.
i use less than half a tablespoon
