If you're someone like me who has never really paid attention to what you're eating so long as you aren't rapidly packing on weight, I recently downloaded an app called Cronometer after being told by my doctor that my blood pressure and cholesterol are too high and to lose weight.

I've been tracking everything I eat and have managed to keep myself between 1000 and 1500 calories a day along with monitoring my fat, carbs, sodium, and protein intake. It has been insanely eye opening to see and feel the difference after cutting out the daily burgers, pizza, and fried foods and its only been like a week and a half. Seeing the numbers in the app makes it almost like a game to see how little fat and calories I can eat each meal/day and shocking to see what is contained with a typical meal that I used to eat (easily 2-3 days worth of fat and calories compared to what I'm eating now in just one meal).

In any case, if you want to eat better, try finding something that let's you tally up what you're eating. From there it's as simple as finding better alternatives (like a low fat dressing instead of regular dressing, or chicken/fish instead of beef/pork) or replacing just one meal a day with something healthier.
