Hi Kerrie,
The most important thing to remember is that any food you eat should contain no more that 5g of fat per 100g (most foods will tell you this on the packet), and each meal you eat must contain no more than 15g of fat in total.
As long as you're sensible and stick to a low fat diet, you shouldn't ever have to experience the orange oil or any kind of leaking
Some people on Xenical just count fat content, others count calories too (myself included), and we also have a few people following Slimming World and Weight Watchers.
Like I say, you don't necessarily need to follow any sort of official 'plan' as long as you're eating sensibly and healthily, and watching the fat content you'll be fine.
As far as specific foods go, it's hard for me to give you specific advice because it all depends what you like to eat!
There are loads of diaries here on the Xenical forum. Why not have a look around and get some inspiration that way? The link to mine is at the bottom of this post, but I must admit, my diet can be a bit mundane, so there are probably better ones out there!
I tend to stick to soups, beans on toast, salads etc. at lunchtime, and for dinner I usually have a low-fat ready-meal with extra veg or salad to bulk it out a bit. Either that or I'll have a stir-fry (using fry-light) with noodles or a home made risotto, chilli etc.
Quorn is pretty good if you haven't already tried it. It's good in things like bolognese and chilli because it absorbs the flavour of the sauce and is nowhere near as high in fat as normal mince. Their sausages/fillets etc. are arrarently pretty good too.
For snacks I tend to go for fruit, Alpen Light bars, Mini Milk lollies, sugar-free jelly, WW deserts, raisins, Oatybars and that kind of thing. And I do allow myself the odd Curly Wurly (these are not within the fat allowance for Xenical but I've never had any problems)
My only other advice would be to drink PLENTY of water (add juice to it if you want to). Xenical can make you a little bit constipated in the beginning, but drinking lots of water will help with that and will help you stay fuller for longer.
And lastly, don't be afraid of the tablets. I know how many horror stories there are out there from people who've had the side-effects, but in my experience, they are the people who didn't make the effort to eat a low fat, healthy diet.
And it's not 'all or nothing' with the side effects either. If you eat a couple of grammes of extra fat, you're not suddenly going to be on the loo all day. Side effects range from slightly oily or orange bowel movements to the side-effects you described (which you won't get as long as you're sensible!)
Good luck with your goals Kerrie, and keep posting. There are lots of people on Xenical here who will give you loads of good advice and support (but I think they're all out enjoying the sunshine at the moment!)
