This is a very late response, but I moved to Davao, Philippines from the US a few months ago. Been doing low/moderate carb for a while before finally going primal last month.
-Filipinos eat tons of rice, but traditionally it is with some sort of meat/veggie dish. Just forgo the rice altogether. Mmm Lechon Manok...
-Eat fresh fruit, but depending on your weight loss/carb intake goals avoid starches like potatoes and ube, avoid high sugar content bananas, mangos and pineapples. Drink Buko (coconut) juice, eat fresh coconuts, cook with coco milk.
- Seafood is always fresh & cheap, there is no organic/grass fed/free range-type meats (or if there are it is definitely not labeled as such) so I would just buy from a wet market rather than the supermarket, because the supermarket gets shipped frozen meats. At the wet market at least you know its local (no refrigeration used). Trim away the fat and add oil/butter when cooking. Make your own ground meats.
Filipinos now also eat lots of SAD junk food (instant noodles, canned meats, cookies, soda, etc.) just avoid the processed food that are becoming standard parts of the filipino diet. The affect of these foods are very obvious, as there is a much higher rate of obesity in children than years ago where the family ate rice with every meal, but with protein and veggies and lots of fresh fruit. My sister is only six but eats instant noodles (pancit) or canned corned beef, beef loaf, or hotdogs with rice for every meal. Her parents eat rice w/ fresh meats and veggies for themselves but she prefers the garbage food so thats what her mom cooks. She is 6 and already is overweight and has cellulite on her stomach and legs. I've tried to explain to my stepmother that she can't eat all that processed food and rice that its so unhealthy, but they just don't get it. My stepmother thinks that she is healthy because she doesn't use oil when she cooks that garbage for her. UGGGHH. I want my sister to avoid the CW exercise and diet that plagued me since high school. Its no fun being overweight...the other kids aren't mean to her now, but I know high school and college were not fun and my weight affected my social life big time.
