Keep doing exactly what you're doing, you're swapping fat for muscle, weak tendons for strong ones, sloth for health. I'm actually worried about your low calorie intake.

You've managed to exercise and diet for a time without getting a cold or flu, or a sprain which will put you out for a month and a half. Keep at it at this pace. In six months you will be amazed.

Personally I'd much rather see women exercise for function than for some crazy image out of Cosmo.

Ohhhh my goodness, I forgot who I was talking too.. I just looked at your gallery.

You're THIN and SMALL as it is. If there are any goals you should seek in working out, if you're seeking looks, it's not a smaller body, it's one that's more defined. You may gain weight but shape your body.

Keep working out as you are, and EAT what you CRAVE until you're SATISFIED. If you can manage to (unrealistically) build yourself to where you're both eating and burning 8,000 calories a day, you will be sooooo fit and sexy. 8,000 calories, though, is lumberjack status, more realistic in today's society would be 3,500. Again, eat AND burn the lot every day, the more you can metabolize daily, the more fit you are. If you listen to your body while you do this, you will know when to take more salad, when to take more meat, and when to take more pasta as you keep moving your body to greater levels.

Hahahaha, oh heavens, I'm not trying to be a model or anything. My weight loss goal is only 10 pounds from where I am now, and that's mostly to tone off some of my excess body fat (I'm aiming for 20% body fat). I'm not seeking looks; I'm seeking to be fit and healthy, to be able to take care of myself, and to get a healthy heart since my family has a history of several cancers and diseases.

Oh yeah, if you can't pronounce the ingredients label, don't buy it.

Muscle is denser than fat, so as you're trimming fat and adding muscle, you will not only not lose much weight, but may gain some. Don't worry about that silly number, and just focus on your level of fitness. And whatever you do, don't pay attention to pseudo-scientific nonsense like BMI and fad diets.

Fair enough. I'm not doing any set diets; I'm merely making sure I increase my fruit/vegetable/protein/fiber intake, as opposed to the rather carb-filled food I have been eating. I've also evened out my caloric intake, so that instead of blood sugar-spiking meals with small snacks in between, I eat smaller main meals and larger snacks.

Any recommendations on how to track fitness?

You seem to be doing pretty good as you are. If you're curious about how your advancing, keeping a workout diary might help. Write down what you do and how much of it, then you'll have something to look back on and compare it to to judge your progress. Not sure, otherwise. It's not something I ever did back when I used to work out.

It sounds like you're taking too few calories and your body is going into hoarding/starvation mode. Might want to relax on the calorie limit, just eat what you crave until you're satisfied, stick with good quality meat salad and low density starch. I wish I could find a reference to this, there are studies which show there's a low calorie threshold where your body starts to fatten up if you fall below that limit.

Even though those articles sound like it's too much food that causes heart attacks, Mirkin's articles are specific to the idea of sudden rise in blood sugar leading to heart attack risk. It's best to take calories without elevating blood sugar and insulin.

and when this 80 year old with BMI of 7% bikes 100 miles every weekend, he eats peanuts and drinks lots of coke.

I usually do eat what I'm craving, to a point. :P I've always believed that if your body is craving something, it means your body is likely deficient in that something. I've evened out my meals, so that I'm eating 5 meals of about 400 calories each, instead of 3 meals/600 calories + 2 snacks/100 calories, to help with the blood sugar spike thing (especially since both parents are diabetic).

I love peanuts. :) That's my morning snack of choice, actually.

Yeah, after listening to Mirkin for a while, it seems like if you're at risk of diabetes you have no choice but to be an outright athlete, else your body goes to hell quick.
