Is this amount of protein right?

usually the guidelines are per lean body mass, or if they are on total weight assume you aren't obese.

15 - 30% or 35% calories from protein is pretty standard for most people. 0.7 - 1.0g per lb of lean body mass might be 100-150g per day.

If you're lifting weights, eat your weight in protien. 200lbs = 200g of protein. Chicken and protien shakes work.

It's supposed to be 1.5x your weight in kg, not pounds!!

Take your weight in pounds, divide by 2.2 (300/2.2 = 136) 136 x 1.5 = 204g/protein per day

They say though that the second number you multiply by (1.5) can be anywhere from .9 to 1.8 depending on your scale of activity - ie., if you lift weights, if you're trying to build muscle mass and lose fat, the higher up you'd go.

For example, my current weight is somewhere in the neighborhood of 160, which is about 72kg. If I multiply by 1.5, that puts me at 109g/protein per day - but I'm trying to reset my metabolism and build muscle, so I've upped it way more than that and have my protein at 30% of my daily calories, which results in a goal of about 160g/protein per day.

It depends on what your goals are. When I was working on building muscle, I was at 40/30/30. Now that I am training for a half marathon, I've changed to 50/25/25.

People get crazy about protein.

I believe the number from a health/weight loss perspective is 1g / kg of body weight (1g per 2.2 lbs)

---> Sometimes I hear it as 1g / kg of LEAN mass (don't count your fat). (This is what I aim for.)

Bodybuilders/lifters suggest 1g/lb or more. Or 2g/Kg if you don't want to mix measuring systems.

When it comes to developing a nutritional plan, the first couple of things you need to determine are your total weight and bodyfat percentage. The bodyfat percentage doesn't need to be 100% accurate, but it will be used to determine your percentage of lean mass. There are a number of websites out there that can use certain measurements to determine your bodyfat %- just Google "body fat calculator", enter your measurements into about 4-5 of them and then average out the results. Based on my experience, there shouldn't be too much variation in the results.

So once you have your bodyfat %, subtract that number from 100 to get your lean mass percentage. Multiply this number by your current weight to get your total lean mass.

For example, let's say you weigh 300 lbs and your bodyfat is 30%. Your lean mass percentage would be 70%, and your total lean mass would be 210lbs.

In order to maintain your current weight, you'd need to consume 210g of Protein every day. Since 1g of protein is equal to 4 calories, you'd be taking in 840 calories from protein.

Now, there's a lot of debate over the ratio of macronutrients in a diet. Based on my experience, the 40/40/20 spilt seems to be the best starting point. You can make adjustments as you go, but this will give you a good starting point. Just like protein, 1g of carbs is equal to 4 calories, but 1g of fat is equal to 9 calories. Continuing with the above example, we've already calculated your protein needs using your body weight and lean mass percentage, wiht is 210g of protein equaling 840 calories.

So, a 40/40/20 split would work as thus:

Protein: 210g, 840 calories
Carbs: 210g, 840 calories
Fats: 47g, 420 calories
Total: 2100 calories
