sandysan said:what if you need to loose lots of weight wont the fat part of it slow the weighloss down ?
here's an online calculator which helps you find how many grams of fat and protein you can have on average per day based on your height, weight, desired weight loss and daily carb intake.

PS. a gram of protein doesn't equate to a gram of meat, you have to find the protein content per 100grams of a foodstuff before you can use it to find your daily limit.
Pluging in my details gives me for 60 grams carbs per day to lose 2 lb a week
72 grams of high quality protein.
This would be supplied by: 12.0 ounces or 337 grams of a high quality protein food like meat, fish, eggs, or cheese, which typically contain 6 grams of protein.
and
Maximum Fat Intake: 63 grams.
