Lol that's exactly what I weigh I'm just 2 inches taller so basically the same. And yes my midsection is the worst too! I feel like no matter how skinny I am that part won't completely go away and it's the one thing I really wish would.
That's a good idea to take pictures in your favorite bikini! I think I will do the same with the measurments, I thought about doing them once a week but I don't want to obsess over the numbers and I know if I wait 30 days then my body is way more likely to have made changes.
I'm not really on a specific diet, but I am a vegetarian so the low protein will problably be a problem here too. I know adding any lean protein would be good for you, it adds plenty of calories and will keep you feeling full longer without adding unwanted fat or sugar or empty calories. (lol i'm so not an expert as you can tell but this is just random stuff I've learned through the years) I'm going to try to up my protein intake by eating more beans and peas. An average dinner at my house: I make chicken or steak or some kind of meat for my FI and I make steamed veggies and some type of starch (i.e. rice, potatoes, pasta) But I think i'm going to start making more beans and peas with the veggies too. I like black beans, garbanzo beans (really high lean protein content), lentils, green peas. Spinach is also packed with protein, and I like salad a lot so i'm going to try to eat more of that even tho I feel like I eat it a decent amout as it is.
I know eggs, milk, chicken, and fish are all excellent sources of protein you could try to incorporate more of those things more. Just adding a glass or two of milk would up your calories 100-300 a day.
As for supplements, my FI takes a ton of them and swears by all his pills and powders and crap. I'ver never taken any but I just asked some ladies on another thread what they use because I might start taking a whey protein supplement after I work out. The two suggestions I got: Dymatize Elite isolate whey protein and Mysofusion. They both got good reviews and are pretty moderatly priced. A lot of the protein supplements out there have a toooooon of calories and sugar in them (for guys that are trying to gain weight) but these two are fat and sugar free so that's a plus.
