When you drink enough water you don’t only replace calorie laden drinks, but you also avoid dehydration which causes a decrease in your blood volume. According to a recent study, when the kidneys detect a drop in fluids they release an enzyme that causes a rise in angiotensin which will not only cause your blood pressure to rise, but will cause fat cells to increase in volume.
LifeTip: Drink your water! How much? If you ask Michael Greger, MD, for healthy adults 9 cups a day of water for females and 13 cups a day for males, taken throughout the day, should keep you well hydrated.
