Realistic goal for dropping body fat percentage

skapo72

I know that with weight loss, a realistic goal is maybe 1-2 pounds a week. What about with body fat percentage? I just started tracking it, and I'd like to know what to expect. I lift weights and I run about 3 times a week. Should I expect it to drop every week, every other week?

I've wondered this myself! Hope someone has an answer.

The method that you're using to measure your body fat percentage is unlikely to be accurate enough to track your progress. The margin of error is likely to exceed the overall percent change that you would achieve. The only accurate way to measure body fat percentage is with a hydrostatic tank or a DEXA scan, neither of which is likely to be something you're able to access on a regular basis.

I disagree with that. Even if your precentage isn't accurate, you can still track the progress. As long as you're using the same faulty method consistently, you'll still see a drop in the precentage (assuming your losing fat).

if you are losing one to two pounds a week, then you are already losing body fat. As for what is a "reasonable" goal that is going to depend on where you are in your progress. For a beginner then just dropping weight will lose to less body fat, so whatever your weight loss goal is will be appropriate.

If you have been dieting for a long time and have had an aggressive goal of say two pound per week loss, then you would benefit from eating at maintenance for a two to four weeks and then setting weight loss for .5 pound per week goal...

OP - how long have you been dieting for?

Nope. Have you used body fat calipers? Even trained professionals can get different readings off the same person the same day... and that's if you're using the most relevant skinfold equation. Since the OP didn't mention being trained in body fat calipers, I'm guessing she's using a body fat scale. I have tried several. They're so inaccurate that if you weigh yourself, walk around the bathroom and weigh yourself again you can get a completely different reading. Hydration level, level of callouses on feet, when you last ate, when you last exercised, how big your last meal was, if you have any sweat or lotion on your feet, etc, etc. all impact the reading.

It's a math problem :-

Let's say you start at 170 lb and 30% fat. ie 51 lbs fat and 119 lbs of non-fat.

If you lose 1 lb/week of weight and 70% of that is fat then the fat goes down 0.7 lbs/week and the non-fat 0.3. This gives a reduction in body fat of about 0.25% per week :

Do you use the gas gauge on your car? It sucks at telling you exactly how much gas is in your car but my guess is, you don't ignore it.
