Thanks everyone.
Sunarie, Ryan - I think my diet lacks protein & Vitamins. I don't know if the lack of these are causing my said appetite, but I will pack up on low-fat/low-carb protein shakes and take Vitamin supplements to make sure.
Freelancemomma - I can understand what you say, I think I too fit in with the group of those large eaters. Nobody in my family side or my hubby's side (or whom I noticed in general) has an appetite for food that tastes 'just ok' -- whereas I will in general eat anything that's on my plate, except particularly bad tasting food - and I will eat well at that! My hubby is generally amused by my eating pattern -- at our engagement for example, he was simply talking and talking and I got so pissed off I started eating all the food that was in my plate and finished it completely whereas he didn't even have a bite!

I would agree there's some of us who are genetically tuned to eat big.
IanG - How thoughtful of you to give advice on those filling foods! Last year when I first started my dieting patterns, I did take a primer on them, but ignored them for most part of the year, amounting to partial regain of my weight. Will pack up on those good foods to control my appetite!
