I learned how to eat from caloriecount, sounds weird but I had the tools on that site to research calories in foods (ya know, no nutrition facts on the side of an apple), a BMI calculator, food log, weight log, and so many other tools to aid in healthy living. As for exercise, I walked my neighborhood (2.5 miles) daily and did a dvd workout (Jillian Michaels 30-day shred) and over a 2 year period worked hard at eating right and exercising and finally reached my goal of 140lbs. I have kept the weight off for the last 2 years (through a pregnancy even) by going to the gym and continuing to eat a healthy diet. It's never been easy but for myself and my family, getting healthy and fit was an obligation. I don't want my kids being obese like I was through my childhood. It's all about making a change you can stick with, there are many ways to drop a few pounds but unless you're eating right and exercising, its not worth it because you haven't changed bad habits and will eventually revert to old ways.
