Key point to lose weight, and for those who want to lose that big belly:

Do not drink any kind of liquids when you eat!!! NEVER!
Drinking a lot of water, juice, or soda can cause digestion problems. Fluids leave stomach faster than solid food, so beverages tend to carry out the digestive juices of the stomach and the stomach is left without sufficient juices to carry on its work. This will eventually exhaust the stomach and cause it to produce more acids, which could result in heartburn or acid reflux. You end up having food staying in your stomach for very long hours (sometimes up to 9+ hours) then when you eat dinner you pile that on top of it. At this scenario, it DOES NOT matter how many hours you run, jog, walk, exercise, etc., you will still have that big belly sticking out.
Some people call this a "Korean Diet"--you can look it up online. I don't know what Korean diet is actually, but I have personally read this somewhere online and have been following it eversince and I feel great. I've also been maintaining the same weight eversince while exercising an average of 2-3 times a week (30-45 minutes each time).
I eat all kinda food, many times a day. I don't count carbs, calories, etc.
