I don't exercise. Heck, I hardly move at all.
"Sedentary lifestyle" is my middle name...
And I drink lots of strong coffee.

However, I *DO* drink a gallon+ of pure water daily.
When I drink less - I don't lose weight.

So water is the key. At least for me.

Drink your water. Drink your water. Drink your water. Drink your water. Drink your water. Drink your water. Drink your water. Drink your water. Drink your water.
