How much water are you drinking while slimfasting and do you think it makes a difference to your weight loss? I know on Cambridge that you 'need' to drink lots of water to aid the weight loss - is slimfast the same?
Have just found a water calculator to help you to work out just how much water you should be drinking on a daily basis, baring in mind your build and weight etc. Thought it might be useful. Hydration Calculator - Drinking Enough Water
