Can't do much about the first one, but I need to get healthier before I die. Soon.

I've always had problems because I love to eat. All kinds of food.

I'm already active with sports, but can only do so much because of my health.

I have terrific willpower in many things, but not with diets.

I know much of what comprises a healthy lifestyle, but I need things that aren't dramatic; won't work for me.

Any suggestions from former fat people on what they did that made a difference?
