welcome to NoS! I hope it works out well for you, like it has for me so far. I'm a little worried though, in case you're setting yourself up to fail by starting with an unrealistic goal. I agree with kevin's comments that 8 pounds in a month is perhaps a little bit quicker than ideal... Sure, you can lose that amount of WEIGHT, but it's unlikely to be fat that you've lost, so as soon as things settle down you'll probably end up putting it back on again. If you're still not convinced, consider that there are about 3500 calories in l lb of human fat. You'd need to run a calorie deficit of 7000 calories a week to burn off 8 lbs of fat in a single month. That means that if you did no additional exercise, you'd need to eat no more than about 1200 calories a day, which is not comfortable, healthy or sustainable... Not to mention the fact that this is not about counting calories, which is dull and soul-destroying in itself
NoS is not quick, but it is very healthy and effective. It's about long term, slow, sustainable weightloss and weight maintainance. I'm 29 and from a starting point of 210 pounds, I've lost just over a stone in weight since I got here (14lb) and my weight is still going down. It's slow though - about 1/2 to 1lb a week. If I weigh myself weekly it's almost too small to be measurable. Yet, I know it's working cos I've lost a whole clothing size and feel so much better in myself.
Anyhow, I hope I haven't put you off with what sounds dangerously like an unsolicited physiology lecture!
Really, the best thing you could count or measure is days on habit. Forget measuring weight, it's unreliable and a poor measure of fitness and health anyway. As long as you're addressing the problem and taking steps to lose weight, what does it matter how long it takes? NoS is a plan to eat like this for the rest of your life, therefore you have the rest of your life before you'll be done. There's no "before and after" pictures here, only "before and during".
Anyhow, I wish you every success. I hope you find peace and health on your journey.
