In short - yeah. I never understood why until the doc explained why water was important - hopefully the good explanation (well good because I understood it!) helps you to!
Firstly, sometimes we don't recognise that our body wants fluid not food and water is the best to hydrate you - its the best moisturiser ever!lol
Now this is the bit that I found interesting - you should drink a big glass of water every time you eat because your stomach is like a garbage disposal. If you put food down a garbage disposal without turning the water tap on, it wouldn't work properly, it would grind and find it difficult to break down. Your stomach is like this - if you drink a big glass of water - you are going to digest your food better.
It made me drink more water anyway!lol
Plus - my skin is amazing since I did and once you get used to it, you don't pee as much and I start to want to drink more water.
Anytime I struggled to loose weight on my previous weightlosses (yoyo dieter here!), if I increased my water consumption (and making sure I was sticking to the plan) I would start loosing again.
Does that help? Hope so! xxx
