Morning ;-)
Im not sure about slowing losses as its fat free, has almost no carbs and i thinks its like 1 calorie! I just bought the berry one on tuesday! Its actually quite nice, although i think the concentration they suggest is tooooooo sweet. lovely in sparkling water with ice mmmm
Yeah its 1 tsp in 1 litre - but i thought you could drink as much as you liked!
enjoy
