My body fat is 30%, and I weigh 152 pounds. How many pounds of fat do I need to lose to get to 20% body fat?

Question

Brian, I don't know if you noticed, but I am a female. Healthy body fat for a female is between 18-25%, because we need more fat on us.12% is healthy for MEN.

Answer 1

1.  TO THE PERSON THAT SAID 20% IS HIGH FOR A FEMALE.. you are part reason there are so many anorexic, 20% is beyond healthy for a female, as 12% for a female is way underweight, women need more fat on their body to function, and to survive.

20% is a excellent goal!

2.  Now, to figure this out is a long process, i'll try to explain..

Take your current Fat % and weight and figure out what your Lean Body weight is. Lean body weight, being the weight of bones, muscles, blood, skin and everythign other then fat!

so, body weight x fat % = 152 x 30% = 45.6lbs of fat, so Lean body weight is 152 - 45.6 =  106.4lbs

Then take your Lean body weight and divide that by 100-goal fat %

so 106.4/(100-20%) = 106.4/.80 =  133

so 133lbs is the weight to get to to have 20% body fat,

which means you need to lose 19lbs

hope that wasent too confusing

Answer 2

Depends on how tall you are.

Answer 3

This section is innundated with SPAM website links!  Most of these people are new users to Yahoo and obviously haven't read the guidelines.  I hope EVERYONE reports SPAM when they see it! ....

You didn't say how tall you are.  Your weight may actually be fine, but you  might need exercising:)  Turn that fat into muscle and you'll reduce the body fat %.  You'll look thinner too, because muscle weighs more than fat (so if you're still the same weight, you'd look trimmer).

Answer 6

If you were able to maintain ALL your lean mass, then it would be a case of losing about 19lb of fat. But it's not possible to keep all your lean mass when drop fat, it's inevitable that you will lose some lean mass.

To keep muscle loss to a minimum it's important to do strength training reguarly and eat plenty of protein. In your case you probably want to be getting at least 100g of protein a day.

Answer 7

10% of 152 lbs = approximately fifteen lbs.

Keep in mind that if you are gaining muscle you won't ned to lose as much weight and that any calorie restrictive diet can actually eat muscle so that 15 lbs is only a roundabout number.
