Living alone is great! There's no one to see you get embarrassingly huffy and red when you excercise! You can eat what you want without someone else making a big pot of spaghetti next to you! Ugh!
Decide on an eating plan. I count calories, but maybe you might try weight watchers and points? Online there are a lot of great recipes for meals and baked goods. You might enjoy that.
I love food too
. Throw out all the crap in your house and buy only healthy stuff! Start now!
Set your goals - how much weight do you want to lose? Losing 1 pound a week, for example, is a realistic goal and people often do better when they start out much heavier. What milestones are important? What kind of rewards will motivate you?
Invest in some dumbells or bands - they're really affordable and make a big difference in what you can do while at home! (In fact, maybe invest in an ipod too.)
You're engineer at 24?? Let me just say WOW! I wish I hadn't puttered around so long, or I could be too. If you can do THAT, you can definitely lose weight!!!!!!!!
