Depinux, yer welcome, mate. These things take time and dedication. Baby steps, mate. Yer doin' good, so far. Jest keep it up. Even working in a kitchen. Get in the habit of keeping celery or carrot sticks in the fridge with ranch dressing. I had one day I ate that ALL day long and not much else (a couple hard-boiled eggs, I think). That day alone I lost 5 pounds. Not recommending doing that on a consistent basis, but whenever you get the urge to eat and don't want to cram yer gullet full of Mac 'n' Cheese.
In Re: Scales.
If you're going to use a scale, don't use a regular scale. Spend 60-80 bucks and get one that measures body fat. That way you don't have to worry about whether you're measuring body weight or muscle weight. Look at 'em online or check out your local home goods store (Linens 'n' Things, etc.). The military used to use BMI and my weightlifter roommate was told he was "fat" according to the BMI.
Broadside, you're taking a good step. There are TONS of bodyweight exercise only people. There's no need to go to a gym unless you want to do weights, aerobics or cardio machines. There's another good book for bodyweight exercise written by Pavel Tsatsouline. It's called "The Naked Warrior". You can check it out at dragondoor.com or see if your library has it. Pavel has written many books (as you will see) and is a regular columnist in SEVERAL bodybuilding (natural, I might add) and fitness publications.
Keep up the good work, everyone!
