If you're trying to build muscle yes but if you're trying to burn fat no. Protein spikes insulin almost as much as sugar does. Insulin builds muscle but it also stores fat & will prevent it from being used as fuel.
Wrong....
When your losing fat it's extremely important to maintain high protein
Your body is in a constant state of preservation and building reserve, which is why it's so easy to get fat. Your body loves fat, and will store fat via insulin spike at every oppertunity.
1 gram of fat=9 cals
1 gram of protein = 4cals
1 gram of carbs= 4cals
So fat per gram more then doubles carbs and protein in terms of cals.
So your body loves fat for those reasons and it's low maintenance on your body
However muscle is viewed as high maintenance on the body.
Muscle causes the body to burn fat faster, and muscle takes the most calories to preserve
So when it comes to losing weight of any kind your body's number 1 option will always be to use muscle as a source of energy and preserve fat energy.
Why do you think long distance runners are always so skinny because there body eats there muscles and using it as a source of energy when the body is put in a position to burn high calories
This is why bodybuilders never run....
And also why they take on more protein when there dieting then when there building muscle in the off-season
Any IFBB PRO or NPC competitor will tell you they take in MORE protein when there dieting down for a show then when there off-season building up muscle
Matter of fact, the closer to the show, the more fat they lose, the more they will increase protein intake because it becomes harder to maintain there muscle with caloric restriction.
Also protein does not cause insulin spikes to the degree of fat gain due to fact it takes the ingestion system longer to break down and process protein then carbs and certain fats. It can take steak up to 24 hours to properly digest under normal circumstances.
The slower the digestion the lower the insulin spike, and most protein via eggs, steak, chicken, and fish have the lowest number on the insulin spike scale.
