Yes, In theory you should drink half your body weight in oz of water daily. For exemple, if you weight 200lbs, you should drink 100 oz of water.

Your brain often confuse dehydration to hunger. Try to drink your daily intake of water and you should be less hungry for snacks.

At first you will go urinate a lot but your bladder will adapt!

Hope this will work for you. For me it worked wonders. Lost 6lbs already in 2 weeks by drinking water and cutting snacks.
