Angie, I've already jumped headfirst into the WLS threads It's amazing what a little support and encouragement and a whole lot of inspiration will do!
Maya, I know firsthand what you mean by a few pounds on a petite frame. My poor petite frame has had to lug around more than it should for a long time! Bust size is the first to be affected by weight (more specifically fat) gain or loss.
I second (third, fourth...) everything that has been said here about diet, portion sizes and calorific deficit. Protein and good fats (like avocado) help to keep you feeling full longer than just even good carbs.
A fistful (roughly 21 almonds) is your allowance per day and makes for a wonderful, filling snack for your salty cravings. Also try asking mum to help you with roasting chickpeas in the oven. They are supposed to be one of the lowest GI grains and another cure for the salty snack craving.
For sweet cravings, the SB diet bars Joy mentioned are great. I'm not a big fan of any other flavours but the chocolate flavour is deelish. I also love cottage cheese with diced fruit (apples, banana etc.) Another thing I do is mix almond slivers and a few raisins (only a few as they are high in sugars) into a third of a cup of ricotta cheese. I love it. I eat it for bfast, as a snack or when I'm craving dessert. Only once a day though. Another power snack creation of mine which I LOVE - one slice of whole wheat bread smeared with a teaspoon of nutella, topped with about a tablespoon of cottage cheese topped with banana slices (1/2 banana). Yum!
I really want to stress the importance of some kind of weight training. It boosts your metabolism like no other. As for the advantages of a lb of muscle vs a 1 lb of fat, here's a good visual - http://charliewall.files.wordp.....muscle.jpg . Plus, as we grow older and lose bone density, strength training is the one thing that will help keep us strong and limber. I really recommend this website for a lot of good information about the advantages of strength training for women, beyond the obvious - http://www.stumptuous.com/
Good luck Maya!
