This is just what I answered to someone else asking about dieting and eating something else. I believe the bottom portion of what I said may help you and your situation: It's just copy/pasted, but read on. I am not one to be funny when it comes to someone feeling uncomfortable with their image.
I think your weight is fine. Your diet can vary from just grilled chicken. Try turkey, fish (salmon), fruits and veggies. Just don't starve yourself. Then you will eat twice as much and blow up back to where you just came from. Maintaining is the key. Dieting is tricky business. I'm no expert, but I have maintained the same weight range for years, and I despise diets.
It's just how much I eat, what I eat, and when I eat. I don't starve myself at all. I think it boils down to portion control, put the fork down and chew, don't eat on the go....and like I said, the times of the day you eat.
Also, don't become obsessed with your weight. Just maintain a healthy lifestyle and you'll be fine. There is no specific way we are supposed to look. Only Americans think that crap (I am an American, but i think like a Japanese)!!
I am a female and our weight fluctuates rapidly, we get bloated, have image issues, peer pressure, the media, etc.... Fcuk all that. I am not going to live my life based around what others think of me. I love me and that is all that matters.
I am a smart, pretty, intelligent, mature, 31year old female who is happy. It doesn't matter my weight, but I am 125 and 5'3. I look and feel great. People think I am very skinny. It's just that when they find out I am 31 and not 16 they are like "wow you are tiny for your age. WTF does that mean??? I just have a small frame. My bmi is right on target too. So, my point is what makes you feel good is key. How your lifestyle is is key. What you eat has something to do with it, but ultimately it's all in the mind.
This was meant to be more encouraging than actual dieting tips. I meant to do that.....***smile***
Good luck.......
