That's what I'm going to find out, since it describes my situation perfectly!
I'm typing this on 7th April 2008, which is the first day of starting my Weight Watchers diet plan. It's kind of a half day working today, since we had relatives round for lunch; everyone had two fresh rolls but I resisted and only had one. Hurrah for me! Especially pleased since I found out afterwards that just the roll (without filling) was 4 points!! Eek!
Anyway we had an hour long walk today as well, so that must have helped.
I think working from home can be a problem since you are always close to food; you can stop working whenever you like or whenever you feel peckish and go and get something to eat, so you've constantly got to resist temptation.
On the other hand though, you have the advantage that you can spend a bit more time in the kitchen cooking nicer dinners, and I am going to attempt a zero point soup recipe later today, plus a low point muffin recipe too. I wouldn't have time to do that if I was working anywhere else.
As this lens - and my diet - develops, I will try answering this question again, but until then give your thoughts below.
UPDATE - So far the answer has to be that it's an advantage. For me, anyway. I don't have to wait for a designated break to have a snack if I feel I need one, and I can fix something healthy instead of being tempted by a chocolate machine. What are your thoughts on this?

Weight Watchers works. Anyone who has ever tried it properly for any length of time will testify to that. But it can take a while to get the hang of how the whole system works.

Basically every single item of food equates to a number of points, depending on what that food is, how much of it there is and sometimes how it is cooked as well. The fattier an item is, the more points there will be in it, which makes sense since you are allocated a certain number of points every day depending on your weight, and this diet aims to get you to eat less fat.

The hardest part of any diet is the first few days, but you need to be able to understand the points system very well if you are to succeed in the long term with Weight Watchers. It's rather like learning a new habit; after a while you will start to look at items of food and know instinctively how many points are in them.

I certainly found this to be true. Although I had my trusty points calculator to hand whenever I went food shopping, I found that after a while I would start guessing how many points were likely to be in something before I actually worked them out. Most of the time I found I would either get it right, or be within half a point or so of the correct figure which corresponded to that food.

The best place to start is to work out how many points are in the usual everyday foods you were eating before you started your diet. This can really shock you into taking action and finding better alternatives without wrecking your diet. You will also start to become more knowledgeable about foods and be able to stretch your points further as a result.

However much weight you end up losing on this diet, it's important to get your head around the points system right from the word go. Once you have, you're halfway to reaching your goal since you will have the knowledge you need to succeed.

When I was on Weight Watchers before, I used to go from normal crisps to low fat ones. They were half a point less per bag, so not too different really.

The only problem was that here in the UK, low fat crisps only come in rather uninspiring flavours. You know the kind of thing - ready salted, salt and vinegar and cheese and onion (which I'm not keen on at the best of times!).

So this time I have decided to open the doors to every flavour I can possibly have. I think the extra half a point is well worth it to stave off the boredom of having the same three flavours all the time, and it feels like I've got more freedom too. My Weight Watcher lunches actually look pretty much the same as they did before, so I think I'm onto a winner here!

LATEST UPDATE: I've lost around 6.5lb so far!
