Activity's good (more walking, less riding). We can burn a lot more calories on our feet rather than sitting around. Develop a mindset of seeking the physically active way to do things (take the stairs, avoid elevators and escalators whenever manageable, that sort of thing). For home exercises I suppose you could work on pushups (if regular ones are too challenging, do girl ones on your knees until you can readily do a dozen at a time, then switch to full pushups -- aim for twenty, eventually).
I think homecooking's the way to go (more control over what we eat, better quality overall), and consider breakfasts to be very important. If you undereat breakfast, or it's not a stick to your ribs type like oatmeal porridge, you'll tend to eat more during the rest of the day to make up for lower blood sugar levels.
For lunch and dinner, watch out for quantity (eat until you're not hungry, do not just keep eating until you're full as that's usually far more food than your body needs). Avoid snacking unless you've really healthy and low calorie food choices at hand (like carrot sticks).
Try not to lose more than two pounds a week (else, you risk finding yourself on the road to a lifetime of yo yo dieting of losing a bunch of weight, but gaining it all back and then some in a few years). Try not to think of the process as dieting but as redesigning your eating routine as something you can sustain throughout your life (as in changing your lifestyle).
Ok thanks! Thins helps allot :D
