I've lost about 20 pounds by:
-Joining www.sparkpeople.com, a free website dedicated to weight loss. Great tips, support, ideas, articles, and self-trackers, etc!
-Counting my calories per day. Don't want to exceed 1300 calories (sparkpeople will tell u how much calories u should consume a day). Lots of sites including sparkpeople have an area where u can find out how much calories a burger has, etc. You'd be shocked how many calories certain foods have!!!!
-Cardio at least 4-5x a week, at least 30 minutes or more. ANything that raises your heart rate. Walking, treadmill, elliptical, etc. If u can't join a gym, get home excercise tapes (highly recommended: Turbo Jam or Tae Bo).
-Weight lifting at least 2x a week. Added muscle bulk raises your metabolism and gives you that lean, strong, svelte look. It WONT bulk you up like Arnie Schwartznegger, women simply can't bulk up.
-Lotsa water. Since I hate water, I add those zero calorie sweeteners to my water bottles. Consuming lots of water raises your metabolism.
-Lastly, the obvious: eat less junk. Just don't buy any junk food to keep in the house. That way if u have cravings, you don't have any junk to eat. A teaspoon of apple cider vinegar keeps cravings away when it comes. Or, simply brush your teeth!
Find an exercise u enjoy, or you will dread it all the time. Being a full time working mom, I found exercising before work is the only time of day I can do it. Don't deprive yourself of the stuff you love, or you will crash. Eat those stuff in moderation and remember to tally up the calories u eat. Keep a food diary with the calories written next to it. It REALLY opened my eyes to what I was eating!
