Pretty much what the title said...
ive heard some people weighting it after cooking, others before so i really dont know...
So, lets say i have some frozen hamburgers... it has a 120 calories per 100 grams... is this the nutritional value before or after cooking?
Since cooking it will make it lose water the weight will drop, so whats the verdict ?

I feel comfortable saying when you are weighing protein sources such as: fish, chicken, turkey, etc., you should weigh it BEFORE you cook it.
I don't want to speculate with other foods such as rice because as we know there is a HUGE difference in weighing out 1 cup of uncooked rice vs 1 cup of cooked rice. LOL

For example, chicken breast has the following macros per ounce raw:
Cals - 31
Fat - 0.4g
Carb - 0
Prot - 6.85g
The last time I cooked chicken, I weighed 49.3 oz raw. The total macros for this was:
Cals - 1528.3
Fat - 19.72 g
Carbs - 0
Prot - 337.71
After I cooked the chicken, it weighed 33.3 oz cooked. Since this has the same total macros (assuming that only water was lost), the macros per oz cooked were:
Cals - 45.9
Fat - 0.6 g
Carbs - 0
Prot - 10.15 g
Now I have macros for the cooked chicken, which I refrigerated. When I take out a breast (which is typically 5-6 oz cooked), I weigh it cooked and multiply the oz cooked by the macros for the cooked chicken. If I weighed it cooked and multiplied the weight times the macros for raw chicken, there is a mismatch and I would have underestimated the cals, prot, etc in my meal. In the same way, at the beginning of the process, I weighed the chicken raw and multiplied the weight times the macros for the raw food. You have to make sure there is consistency between the food and the macro ratios you are using. Raw food -> raw macros. Cooked food -> cooked macros.
The reason I start with the raw macros and re-calculate the cooked macros each time I cook a batch of chicken is that the water weight that the chicken loses in cooking varies, so the cooked macros will vary a little from batch to batch, and consequently, the raw macros on the nutrition websites are more accurate than any cooked macros you might find on the nutrition sites. I have a spreadsheet that does this, so it only takes a minute. Weigh the total raw chicken and the total cooked chicken and plug those two numbers into the spreadsheet, and it gives me the cooked macros for that batch.
Sorry for the wordiness. Cliffs:
- Weigh total chicken raw
- Multiply by raw macros for total macros in chicken
- Cook chicken
- Weight total chicken cooked
- Divide total macros in chicken by weight cooked for cooked macros
