Hey cyyssg,
I'm also from Singapore and following Protein Power more than CAD but I've read the books and after a while, tweak the regime to suit myself better. I give myself Reward Meals every Sunday when it's family day but am good throughout the week (I try anyway)
Options are added after two weeks to monitor how your weight loss has been going and to cater to your needs (maintain weight, losing too fast/slow etc.) accordingly.
If you have to ask about eating out in Singapore, I guess you don't get out much eh?
There are so many options and since I plan where we dine on Sundays, I always find a myraid of choices and am always at a dilemma. I understand that Chinese food can be tricky, but because I follow a low fat / low carb diet, I stay away from fried food (yes, that means no fried wantons) and starchy stuff (banish the sweet & sour pork!). Have the crispy skin chicken (I prefer not having the skin), beef tenderloins and seafood. For hawker fare, lots of options that are zero-carb. Bak ku teh, pepper crabs, kway chap, duck, soups (not Szechuan, wanton or shark's fin though - go for miso, water cress or fish head) and tofu.
Just stay away from the obvious rice and noodle dishes and sushi. For snacks, there's Otar (1g carb), Taukwa pok (1g carb), BBQ chicken wings (0g carb) satay without gravy (2g carb) or a dim sum prawn dumpling (3g carb). Even beef rendang and curry mutton are 1g carb each.
Or better still, take a break from Chinese food (which often add corn starch to their sauces, you can request for the chef to leave out the ingredient).
Try italian - go for veal or chicken piccata, scaloppini, antipasto and sauteed portobello mushrooms.
Indian - lamb curry, kebabs and tandoori chicken.
Japanese - miso soup, grilled cod fish, shabu-shabu and sashimi.
Thai - tomyum soup, beef with basil, mixed vegetables.
See? your possibilities are endless. Just remember your meat, seafood and salad rule. Other tips for dining out would include requesting for the sauce to be served seperately, subsituting the baked potato/fries for a salad and voicing your dietary demands. However, if you're following the CAD plan, you can always incorporate your Reward Meal during times when you dine out. It's always easier to control carbs when you prepare the meal yourself.
Good luck and have gastronomic fun! I hope I've been of some help.
