If I want to consume.... (numbers)

[Sexual]

I want a macronutrient profile to be 50% of calories, 30% from protein sources, and 20% from fats. I'm eating four to eight meals daily. I already know what foods I'm eating, I know what's the most healthy, and I know my distribution of them through the day.

I just want to get my actual numbers of calories, protein, and fats to be more precise. Does anyone know the math I can use to get my results? I'm not asking you to do it for me, which would be great though, but with those percentages I need something to help me calculate. (ex. 1.2 g of protein per bodyweight)

I would guess I'm 10-15% bodyfat and 200lbs. I've been bodybuilding for a few years.

Oh, and here are my current numbers. This might be a bit too much, but I'm not sure.

TOTALS (APPROXIMATE) - Calories: 4170; Protein: 369; Carbs: 449

 

[EFFORT]

For protein and carbs multiply the total by 4, and for fat multiply by 9

1476 calories from protein
1796 calories from carbs

this means ur getting 898 calories from fat which is 99g of fat


What is your goal by the way?

You want zero calories from protien. That should go only towards building muscel. If you are working out frequently, your body shouldn't use protien for calories. It only uses protien for calories if you are getting too much protien, or too little carbohydrates.

Do you quite understand what a calorie is? One KCal is the amount of energy required to heat 1g of water by 1 degree celcius. No matter what, there are calories in food. You need calories to repair muscle, you need calories to perform every day functions. You will use protein as calories, you can't change that, however, proteins main function is muscle tissue repair. Carbohydrates have their own purpose, and fats as well. Your body uses EVERYTHING as calories, whether you want it to or not. It just has different effects based on what you're eating. Water is the only thing without calories. Now, if you meant for energy in the way that carb do, then that may be a different story.

As far as I know.

As far as I know, in order for protien to be used as energy, it is converted into glucose or fat. The nitrogron group on the amino acids is removed, and the rest is converted into a fat or carbohydate. This only happens if your body has too much protien (your body is developed to find a use for all nutrients you abosrb), or your body has too little carbohydrates to maintain your body's blood glucose. This is harmful process, the extra nitrogen will do damage to your body.

Foods that have protiens also have calories from fat or carbohydrates.

Thats what I figured you meant. You said used as calories, not as energy. Protein automatically has calories in it, which is why I went on that little lesson rant. To say you want "zero calories from protein" is basically saying that protein is water, and that you want none of your daily caloric intake from protein. Either that or it's saying that protein calories don't count, which in fact they do.

Energy is a different story, but in that aspect I believe you are correct, althought I do not know the whole process.

Which is why we hear about all those folks on low carb diets dying of nitrogen poisoning, right?

Drink an adequate amount of fluid to keep yourself hydrated and your output nearly clear (non-yellow) and your body will process as much protein as you can scarf down.

 

[spesmilitis]

Isn't calorie a measure of energy? If you can't use it for energy, why does it have a calorie value?

I think in order to process as much protien you scarf down, you need places to put, like muscels which are damaged from working out.

In america, sympotions caused by the excess nitrogen in the body take a while, but in 3rd world countries where not much carbohydrates are availible, its a serious problem. Most of the protiens they eat get converted to gycogen in order to maintain their blood glucose.

spesmilitis,

I agree that with too much protein, the excess AAs will be deaminated (remove the nitrogen) and the used in another metobolic process (ie dumped into aerobic respiration pathways). The excess nitrogen will be overwork the liver and kidneys, and will be excreted as urea. For someone who weight trains, the recommended amount of protien for a positive nitrogen balance is 1.4 to 1.8 g/kg body weight per day.

A Kcal is Kcal.

Energy density is 4 kcal per gram CHO and protein. 9 for lipids. 7 for Ethanol (which is metabolized more like a fat).

Use an online program to track your diet intake. It will calculate everything for you.

If you put a demand on the body (through heavy training) then it will utilise far more protein than that - I take in 4-5g of protein per kg bodyweight and my urine is clear as long as I hydrate myself adequately (also eat high fibre and supplement with calcium if your diet is lacking).

Your body uses a proportion of protein just to maintain itself before it even thinks about repairing muscles and making them bigger, also some protein will invariably used as fuel for activities throughout the day, broken down when doing cardio, etc. Hence why it's sensible to keep it as high as possible.

Ethanol is alcohol, which isn't part of our food pyramid folks.

Again... Folks in developing countries generally have trouble getting a hold of quality protein sources, not cheap carbs. They also have trouble getting a hold of the kind of quantities of clean fresh water that we're taking for granted in this discussion (1-2gal of drinking water, nevermind water for other purposes).
