I have no Dexa scan places in my area, so I'm trying to figure out how much fat I've lost since starting my new workout program 2.5 months ago. I have only lost 3lbs scale weight in that time period, but lost 4.5 inches overall.

I am 39, 5'3 and currently 140lbs.

The Navy calculator based on my measurements is showing me as having gone from 32% body fat to 28% body fat.

It also says I am -7lbs of body fat and +4lbs of lean mass. Is this possible in 2.5 months? I workout 30 min a day, 5 days a week doing P90X3.

    No internet BF% estimator is accurate.

    Ok, I have a caliper and that doesn't seem accurate either, or I just can't get decent measurements....

    None are accurate, even DEXA has a margin of error. Just be consistent when you measure so at least you can gauge the trend.

    Ok, I was more just interested because I am not losing much scale weight, but consistently losing inches.

    Sometimes our losses get masked by water weight. Especially where you're working out.

    Yea those internet calculators aren't that great.

    Do you have progress photos to compare? Losing inches is a great sign. Using the scale, measurements, photos, the mirror, how your clothes fit, gym progress.. etc. These are all great ways to measure results.

    I would keep on keeping on.

    It's not accurate for me.
