Drink only water. It’s one of those ripple effect things that improves every other area of your life.

I work in a welfare office. The number of people who are both 1) unable to afford proper nutrition (supposedly), and 2) morbidly obese is counterintuitive until you see the enormous sodas so many people travel with. It’s incredibly easy to drink more calories than you think you’re drinking, and the fattening nature of these drinks is all in the sugar content. Switch to carrying water instead of soda or other sweetened beverages and I assure you the following will happen:

-You will save more money than you imagine,

-You will sleep better,

-Food will taste better,

-You will have more consistent energy throughout the day,

-Your skin/overall appearance will improve, and

-You will lose weight.

If you do nothing other than stop spending money on soda/sweet tea/etc and just drink filtered tap water, you will thank yourself.
