Why do you have to be in your home? By far, the easiest way to burn calories is to go for a jog (or a walk) through your neighborhood. It's fun, it burns lots of calories, and its free.
I lost about 55 pounds last year. I think the main secret to losing weight is simply DISCIPLINE. People go around debating "which diet works." The truth is, ANY diet works, if you ACTUALLY DO IT. Most people try out some "diet," but they don't follow it. Then they throw up their hands and claim it doesn't work.
My advice for diet:
- In the beginning, don't eat more than 1500 calories a day (I actually would eat even less than this, but for a male that's not really enough food).
- Eat five meals a day at 300 calories each. If you spread your meals out throughout the day you can cut your calorie consumption in half and your body won't really notice it that much. Eating many meals throughout the day also keeps your metabolism going.
- Eat foods that are high in weight but low in calories. Foods that weigh more give more satiety. Also, fiber and protein provide a lot of satiety on few calories.
- BAD - Trans fat, sugar, sodium, saturated fat (do not eat red meat and most white stuff)
- GOOD - Fiber, protein, unsaturated fats, vitamins and minerals. Eat lots of plants -- leafy, green vegetables like spinach are very low in calories and packed to the brim with nutrients. For proteins, go with lean proteins such as salmon, tuna, chicken, or turkey. Spinach and salmon are pretty much the two best things a human being can put in her body. If you must eat bread or pasta, make sure they are whole grain.
As for exercise, just do SOMETHING. Walk at least 3 miles a day. It's not hard. After I got into better shape I would run five miles a day. I actually got to the point where I felt weird if I didn't work out during the day. Exercise can actually be kind of addicting.
