You sound very slim to me! But if you MUST lose more: I recently honestly changed my life with an eating plan I found. I've always been slim and healthy WITH MASSIVE EFFORT, massively slow metabolism-perhaps even light thyroid issue, I never checked, massive eating discipline and exercise...always battling a few pounds like everyone else.....finally at 42, I was completely unable to lose a lingering 20 pounds I gained AFTER losing weight from baby #3 (now 3 years old and I gained the weight about a year ago without realizing it). I was eating as healthfully as humanly possible with my lifelong nutrition knowledge, and exercising as much as possible, and the weight was just not going way. I was starting to think, "At my age, maybe I just have to admit I can't be skinny anymore and I just have to love and accept my "thicker" middle-aged self and continue eating well and exercising for my health even though the weight never drops." SIGH. I reached out for advice from my co-exercisers at gym etc, but I was giving up, because I already ate healthier than anyone there and worked out as much or more.
THEN, I cleaned out my basement and came across the old book from 80's "Fit For Life" which I never read. I decided to read it, and then I tried it. WHAM I lost 15 pounds in three weeks and I'm still doing it 3 months later with tons of energy and clear skin, and I've gotten back to my skinny NY size (23 pounds lost total) from before all three kids. Most of all I have tons of energy. Now even if I don't exercise for a few days or a week, I don't gain weight. I'm just naturally thin because I eat healthy food the RIGHT way for my body to process it more easily and take maximum energy from it. It's a lifestyle, not a diet, so you have good days (most of the time) and bad days (Thanksgiving etc), but over-all, you never need to quit doing it because it's healthy and feels great. I would have dismissed it when I was younger and thinner, feeling like the theories on protein were wrong (it does NOT go with current fitness gurus who claim you need to eat healthy complete proteins all day long...I've BEEN doing that all along and was fat and exhausted-so my mind was open).
Anyway, my weight loss was so fast, I actually had a belly skin sag issue, but that has passed and now my waist is thin (from work-outs) with just some wrinkles where my stretch marks are since I no longer have a poochy belly to keep the wrinkles at bay. :( But all my work-outs are easier because I have so much more energy. People who haven't seen me in a few months are taken aback and comment immediately that I look great or I've lost weight.
Read the book, the library probably has it. You don't even have to cut carbs, just eat them with enough raw veggies, and don't MIX them with proteins in same meal and a few other rules, but you don't have to go hungry. I'm never hungry unless I find myself out running around for hours with no proper food options...but if I'm home I just eat when I'm hungry.
