so basically, i weighted by chicken breast right after taking it out of the fridge and it was 225 gr, and the package says
there is 23g of protien for each 100g.
after cooking/grilling/whatever (i use the toaster), i weighted them again, and the new weight was 120g.
so my question is, did i intake
1) 2.25* 23protien --> ~52
2) 1.2 * 23 --> 27.6

please help, and thanks in advance :)

Look in the food log for how you weighted the portion you actually ate - as in chicken breast grilled or cooked versus chicken breast raw.
When you are preparing a soup or stew you would build your recipes total calories by adding up all of the raw ingredients you used for the batch then splitting in to the number of portions you divided the batch into. The recipe builder here on MFP helps you do that.

When you grill meats you measure the cooked portion that you consume so you would slice and weight the cooked portion that goes on your plate or in your sandwich etc.

That is why the calorie charts have more that one listing for many meats and proteins - raw vs cooked accounts for the water weight that is lost in the cooking process as well as the cooking method - fried vs grilled vs braised etc.

frozen stuff has lots of water in them, when you allow naturally to defrost you see a big puddle in the end

so I am guessing you had about 130-140 g of (raw) chicken, the grilled weight is much closer to the actual raw weight than the frozen one.

thanks for the responses
i do my weighting after the chicken has been thawed, and after getting rid of the water that resulted
so if i choose "CHICKEN BREAST RAW", would i be getting the nutritional value closest to what i just ate?

Of course, you are not losing calories or nutrients by grilling or cooking, just water*. I always use raw.
(you may lose some of the vitamins of certain things like vegetables, but that is a different story)

*Oil-butter sauteeing, baking, frying is different, obviously. That fat would need to be added to your food.

If you eat the entire amount that you weighed raw after it has been cooked then you are getting that much protein etc. If you are only eating a portion of the amount you measured raw then you should use the nutrition values for cooked chicken breast and log the weight of the cooked chicken you ate.

You are only losing water weight and with some fatty meats some of the fat is lost in the cooking process. It doesn't really matter which way you measure as long as you are weighing you full portion and are consistent in you logging practice.

If I'm cooking a single breast and will eat the whole thing then I could log it either way. If I do up a bunch of large breasts and only eat a few slices then I log it as cooked and weight the amount of sliced breast I have in my meal. It is useful to use cooked weight when you eat out and are trying to estimate what you had in your meal. If I'm doing up a pot of soup I log the raw weight and divide by portions. It all depends on your circumstances.
