Having a problem figuring out protein grams into ounces

Holly IN · 07-29-2009, 12:29 PM

I had to take this information to my dad who is a math genius and he still can't figure it out. He thinks my numbers are all wrong.

According to the calculations I am to have 54.76 grams of protein daily. Which means 18 grams of protein a meal. Now here is where I am having trouble with :

Converting!!

I am trying to figure out how many grams is in a .41 pounds of steak. I am going by the package that is stated from the grocery store. I know 1 pound is 16 oz. I know 1 ounce is 28 grams. 18 grams per meal equals .63 grams. According to calculations I had way too much protein in one sitting.

Is there a better way to calculate??

Thanks!!

Remember that gram in weight of a piece of meat does not equal one gram of protein. Meats are not pure protein. A rule of thumb is 1 oz. of meat or fish equals approx 7 grams of protein.
Your steak was about 6.5 oz., which equals about 45 g of protein.
Here's a website that explains it...
Protein - High-Protein Foods and Amount of Protein in Each Food

Did you calculate your minimum requirement from the PP book? If not, I suggest that you do. Remember that those are minimum values for a day. You won't necessarily split them evenly throughout the day.

I did calculate according to the PP book. Thanks for the website. I am going to check it out.

Ok one way of figuring out is to look at the meat and measure by eye with an imaginary deck of cards, right?

Holly, there's nothing wrong with your math. The problems is that you have 1 oz having 28 gm of protein. It only has 7 gm. 28 gm is a 4 oz serving - the proverbial 'deck of cards' size. (This applies to animal sources - beef, chicken, pork, fish etc. Cheeses are different.)

If you have PP, take a look at the "Protein Equivalency Charts" starting on page 154 in the paperback edition. The first chart gives you several foods that can help you reach your 60 gram of protein per day (i.e., 20 per meal).

You can go higher; these are minimums. How do you know if you should go higher? If you are hungry, eat more.

You can satisfy the 20 grams per meal with 3 ounces of meat, or 2 eggs plus 2 egg whites, or one half cup of tofu, etc. Read across for one food, and down for another to find that you can have 2 ounces of meat and 1 ounce of hard cheese.

If you are hungry, eat more. Some people go as much as 50% over their minimum without any apparent ill effect.
