Good for you! I was in the same situation last year. I was 225 and 38% body fat. Today I'm 170 and 21% body fat, goal is to drop to 160 and sub 20% then add more muscle!
It's been tough, but easier than I thought. Here are some things that I wish I knew when I started my fat loss journey, but you've already got the most important part down - you want to change for yourself, not because someone told you you should.
1. Lift weights! Heavy and often. Go to
www.bodybuilding.com and check out the Losing Fat forum, read the stickies and go from there. Cardio is great, but just cardio will leave you skinny fat, not where I wanted to be. Take it slow at first.
2. Count calories - some people don't agree with this - I do, but you don't have to do it always, just for a week or two then you have a great idea what you should be eating. (I'm eating 2000 cals a day, down from 2500 where I lost a steady 1-2 pounds a week, hit a plateau and dropped 500 cals to get through it). Use
www.sparkpeople.com to track calories - easy free calorie counter - I don't trust sparkpeople's recommendations on how many cals I should be taking in see bodybuilding.com's stickies for that.
3. Eat 5-6 meals a day. I'm always eating and never hungry. It was hard to go from 2 meals a day (lunch and dinner) to 5/6 meals a day, so do it slow, ease into it, start with consistently getting 3 meals a day, then add a fourth and so on...
4. Don't worry about fat burners/diet pills - these can help MUCH later down the road, but the key to fat loss is DIET DIET and then DIET. Clean it up. The only pills I feel someone should take are a good multi-vitamin and fish oil pills when they first start.
5. Eat whatever you want - for 1 meal a week only. I'd go NUTS if I couldn't have Ukrops (grocery store where I live) potato wedges every so often, so I allow it once a week (usually friday or sat night).
6. Find substitutes for your favorite "bad" foods. I like pizza, now I make a whole wheat pizza dough, my own sauce and top it with italian turkey sausage. Delicious and only 400/500 cals. (PM me for recipe if you want).
That's a little more than I anticipated writing, and these are my OPINIONS only - always consult a physician if you have any concerns with your program.
Oh yeah - water is your friend.
