Cooking meat and changing the nutritional profile....

[#8]

When I look at the serving information on the side of my UNCOOKED lean ground beef it says:

Per 100g / 210 cal
Fat - 15g
Protein - 20g

When I cook this meat, most of the fat drains off, and I can even further rinse it with water to remove almost all the remaining fat. Not all the fat will be removed of course, but I do not want that anyway.

My question is, if 100g of uncooked beef results in 20g of protein, then isnt it logical that 100g of cooked ground beef should contain more protein per serving? When I weigh out 200g of cooked ground beef to attain the 40g I am looking for of protein, am I not receiving much more than that because it is now denser in protein per gram? If I actually weighed the meat after I cooked it I suppose I could come with a figure telling me exactly how much weight has been lost in the cooking process to help me determine the exact amount of ratio that has been altered.

How can I know exactly what the difference is according to my cooking method?

If there was 20g protein per 100g of meat when uncooked...lets say the cooked meat now weighs 80g because most of the fat has been drained off. Then you still have 20g of protein total but per 80g of meat not 100g. So the actual amount of protein per gram has changed yes (its gone up) but the total protein content has not.

I thought so.

Use precooked weight, ignore cooked weight.
ie. If there is 20g protein per 100g uncooked, you cook 400grams and want 40 grams of protein, just divide the cooked yield in two. There isn't really anyway of knowing how much fat/water will be lost through cooking (unless you measure before and after) and this number could vary quite a bit depending on cooking method and time. While the raw macronutrient numbers are just an average of previous samples which have been tested in a bomb calorimeter and not 100% accurate to the package you have, its the closest you can really get.

Rising the beef under water will not really get rid of very much fat...as we all know water and oil or fat do not mix...so the fat cannot mix with the water and wash away...it will actually repel the water......

You are talking about emulsification,, and you are right, but we arent trying to emulsify the water and oil, you want it to repel, and seperate, and wash off.........Check out the bottom of your sink when you finish rinsing the beef, i assure you, it washes away from the meat.....No question...;)

I weigh all protein cooked. Heat liquifies fat and thus you are able to drain it...if it is ground beef. Rinsing with hot water will also remove more fat but you dont necessarily want all the fat removed.

This is where a lot of people mess up on their diets ,because they will be taking in to many cals for the day ( could even be 400-500 cals more per day = 3500 cals per week )

So how much protein and fat is in 100g of cooked ground beef then? How do I figure that out?

[Talo]

Basic Math ( as long as I'm right with this :) )

If 100g of uncooked = 20g protein and 100g of uncooked = 80g cooked , Then that would be 1.25 differece so if you weigh out 100g of cooked ground beef you must times that by 1.25 to give you 125g , which would be the uncooked amount .

So , 100g of cooked meat will be 25g of protein ( 20 x 1.25 ) This is going off the 100:80 ratio.

I'm not 100% sure if this is correct , but this was an easy way for me to figure it out. :D

Again the amount of protein will not change...only the fat content as some is removed by heat. If you weigh your protein cooked... then beef and chicken are approx 7g per oz...8 oz cooked chicken would be 56g pro...if you are off a few grams here or there it really wont matter much.

^^^^^^ ??????

100g of cooked ground beef definitely contains more protein because it has lost the weight of most of the fat in the cooking process.

Obviously there is no "extra" protein in this meat that just landed in there magically, but per 100g, it has become more protein dense.

Talo I understand your math, and it makes sense, but where did you get the 20g figure? How does exactly 20g of weight change per the 100g every time?

[JifeLacket]

It'll be similar because everything is ground together therefore evenly distributed so variance will be minimal. I just looked at a website, in 85% lean beef there is going to be ~22g protein in 85g COOKED weight. So 100g almost 30g protein.

You are making something very simple...very complicated. Start with 100g weighed uncooked meat lets say x amount of protein....then you cook it....it STILL has x amount of protein(whether its more dense or not doesn't matter)...no more, no less...the SAME. So there really isn't any math to do at all...all you need to do is cook your meat and then weigh it...voila...easy as pie...speaking of pie...desert time!!!

Anytime you cook meat you will get a 20% shinkage or loss give or take.....

I was just using numbers instead of letters :) I'm not sure how much protein is in 100g , but the numbers can be substituted .

I thought #8 wanted to know how much protein would be in 100g of cooked meat if 100g of uncooked meat = x amount of protein.

Yes , yor going to get shrinkage , but 100g is not the same as 100g :)

This makes sense, except that I cook up a whole bunch of beef at once, then weigh it out for portioning AFTER its cooked.

Therefore the 100g that Im weighing out must have more than 20g of protein.

Im trying to get between 40-50g of protein per meal from this, and I dont want to eat more than I have to, thats why Im asking.

There is no way we can tell you how much water you evaporate off of your ground beef while cooking it and how much oil/water you drain off it afterwords.

If you insist on using the precooked nutritional information then just weigh the batch of ground beef before cooking, then after and adjust the ratio as mentioned earlier. Or weigh it before and decide how many portions it will be, then just divide it after its cooked... same thing either way, 6 in one hand a half dozen in the other.

Other then that you could google for a cooked nutritional information, which will be less accurate because it will estimate the amount of water/oil weight lost through cooking, but probably easier and maybe best because you seem to be having a lot of trouble with this.

[Talo]

100g of cooked is 25g protein if your uncooked is 20g.

So eat 200g to get your 50g

Done.

As i said its very simple....cook all your meat....put in in the fridge....when you need to eat take 7 ounces (45-50g protein) and you are perfect...very simple. As i also said before cooked beef or chicken has roughly 7g of protein per oz give or take...very simple.

Time to eat...take cooked meat....weigh 7oz ....heat it up....eat! Every single client for the last ten years does this 3-4 times per day...its not rocket science and it doesnt matter how much is protein is in 100g uncooked, cooked blah blah blah...this is simple stuff dont make it complicated.

^^ fair enough.
