Have you ever wondered why a slice of cooked meat weighs less than raw meat? It’s not because the cook took away some of the meat. it’s because cooking actually changes the weight of the meat.
There was a dinner party at my house a few weeks ago, and I decided to cook a beef tenderloin for the main course. I brought the beef home from the store and placed it on my kitchen scale. The label said the raw tenderloin weighed 3.5 pounds. I knew that wouldn’t be the weight of the meat after I cooked it, but I was curious to see how much it would lose.
After I seared the beef and put it in the oven to roast, I checked the weight again. The roasted beef tenderloin weighed 2.75 pounds. So, in this case, the raw meat weighed 25% more than the cooked meat. One of the studies also stated the same result about cooked meat.
Are you surprised? I was. I didn’t expect such a big difference. But it makes sense when you think about it. Cooking drives off moisture, and moisture is heavy.
Does Meat Weigh More Raw Or Cooked? Meat weighs more when it is raw, it contains a lot of water. That’s why a raw steak is so much juicier than a cooked steak. However, that water weight is simply dead weight.
It doesn’t add any flavor or nutrition to the meat. In the process of cooking meat, the heat causes the water to evaporate, leaving behind only the good stuff.
That’s why a cooked steak tastes so much better than a raw one, all of the unwanted water has been removed. And that’s also why cooked meat weighs less than raw meat.
The Difference In Weight Between Raw And Cooked Meat
The variation in weight can be properly calculated using mathematical formulas. Raw meat typically has more moisture because it has not been cooked. When the meat is cooked, the water inside the meat evaporates and leaves the meat.
This can be measured by calculating the weight of the cooked meat minus the meat’s raw weight. For example, if a raw meat tenderloin weighs 4 pounds, and the cooked meat tenderloin weighs 3 pounds, to calculate the difference in weight, you would subtract the weight of the raw meat from the weight of the cooked meat. In this case, the difference would be 1 pound. For this you can use the formula:
(Cooked meat weight – Raw meat weight) / (Raw meat weight) X 100 = % difference in weight
In our example, the calculation would be:
(3 – 4) / 4 X 100 = -25%
This means that the cooked meat in our example weighs 25% less than the raw meat.
There are a few things to keep in mind when using this formula:
- The weight of cooked meat will always be less than meat weight in raw form.
- The % difference in weight will always be a negative number.
- The more moisture there is in the raw meat, the more weight it will lose when cooked.
- The less moisture there is in the raw meat, the less weight it will lose when cooked.
Raw Meat Weight Vs Cooked Meat Weight – Table Representation
Following the formula for calculating the change in weight between raw and cooked meat, let’s look at some examples.
In the table below, you will find the weight of different types of raw meat, as well as the weight of those same meats after they have been cooked. As you can see, the cooked meats all weigh less than their raw counterparts.
Type of meat | Raw weight (oz) | Cooked weight (oz) |
Beef tenderloin | 4 | 3 |
Mutton | 6 | 5 |
Pork tenderloin | 5 | 4 |
Veal | 7 | 6 |
As you can see, the weight of the cooked meat is significantly lighter than the weight of the raw meat. As a result of cooking, moisture is driven away from the food, and moisture is a heavy substance.
How does the weight of meat change when it is cooked?
During the cooking procedure, it starts to lose water. The more a food cooks the weight will decrease as muscle fibers break down and become tender or juicy depending on how they’re cooked, few may even appear pink in color because of this process. Lastly, there is the connective tissue which breaks into smaller pieces making chewing easier for us humans who like our meat seemingly delicious
All of these changes mean that cooked meat will have a different weight than raw meat. If you’re trying to figure out how much-cooked meat you need for a recipe, it’s best to use the weight listed on the package of raw meat. For example, if a recipe calls for one pound of cooked meat, you’ll need to start with about 1 1/2 pounds of raw meat.
The difference in taste between raw and cooked meat
We all know that raw and cooked meat has distinct flavors, which is often argued between people. Several people say that the flavor and texture of cooked meat are better than raw meat, while others believe that raw meat is more flavorful. There are pros and cons to both sides of the argument, and it is ultimately up to the individual to decide which they prefer.

Cooked meat typically has a milder flavor than raw meat, because the cooking process removes some of the strong flavors that are found in raw meat. This can be a good thing or a bad thing, depending on your preferences. Cooked meat is sometimes considered bland by many people, while others appreciate the fact that the flavor isn’t as intense.

The texture is another important factor to consider when talking about the variations in taste between raw and cooked meat. Cooked meat is usually softer than raw meat due to the cooking process breaks down some of the proteins in the meat. This can be seen as a positive or negative attribute. Few people find that cooked meat is more tender and easier to chew, raw meat is believed by others to have a better texture than cooked meat.
Do raw meat and cooked meat contain the same amount of nutrient value?
When you cook meat, you are essentially doing two things: denaturing the proteins and breaking down the fats. Denaturing proteins is when the heat causes the molecules to unwind and change shape. This process makes them more easily digestible for your body. Breaking down the fats means that the fat is being rendered, or melted down.
So, does cooking meat actually affect the nutrient value? Yes, cooking meat does change the molecular structure of the proteins and break down some of the fats. However, this also makes them more digestible and easier for your body to take in nutrients. So, while cooking meat does change the nutrient value, it does not necessarily mean that it decreases the nutrient value.
Cooking meat does indeed change the nutrient value, but that doesn’t mean that it’s bad for you. The body usually absorbs nutrients more easily when meat is cooked.
Which meat should you prefer to eat? Raw or Cooked
There are some potential downsides to eating raw meat. In the case of raw meat consumption, food poisoning is the greatest risk that you may face. There is a possibility that raw meat may contain harmful bacteria that can cause illness as a result. If you are going to eat raw meat, it is important to make sure that it is properly handled and cooked before consumption.
On the other hand, cooked meat may not be as flavorful or as tender as raw meat, but it is generally safe to eat. If you are looking for the safest option, cooked meat is the way to go because it poses the least risk for food poisoning. If you cook raw meat, you may be able to eradicate harmful bacteria that are present in raw meat.
In order to destroy potentially harmful pathogens, meat must be cooked to a temperature that destroys them. In spite of this, raw meat still contains disease-causing pathogens. It has been shown in one of the studies that eating raw meat greatly increases your risk of developing foodborne illness, and therefore you should proceed with caution when eating it.
Conclusion:
Having made the above observation, it can be safely stated that raw meat weighs more than cooked meat due to the loss of water content at the time of cooking. Moreover, cooking meat also makes it easier to chew and digest as the muscle fibers and connective tissues break down. However, calories and macros remain unchanged. Finally, it can be concluded that cooking meat does not decrease its nutrient value but actually makes it easier for the body to absorb nutrients.
FAQs
Why does meat shrink when cooked?
The water contained in meat is evaporated when it is cooked. This means that ounce for ounce, cooked meat will actually weigh less than raw meat. A cooked piece of meat may look tender because it is tearing down muscle fibers.
Can we cook meat to preserve its weight and quality?
This is not true, in general, cooking meat will cause it to shrink in size, and this shrinkage will affect the quality and taste of the meat. Therefore, it is important to cook meat properly so that it does not become dry or tough.
Do calories or macros change when you cook food?
There is no change in the number of calories or macronutrients when you cook your food. The cooking process simply changes the weight, texture, and flavor of the food.
