How do you figure % prot/carb/fat

When someone says they eat 40% protein, 30% carbs and 30% fat...how do they figure that? Do they just read the food label and look for prot/carb/fat %'s and stay as close to 40/30/30 as they can? Do they measure and weigh everything they eat? That isn't feasible for me. Is there another way? I read food labels, but I don't know how to relate the numbers on the label into percentages. For example, if I want to go with the 40/30/30 do I need to plan out my food intake each day? If so, how would I do that? Basically I want to adopt a percentage diet. How do I know what I can/cannot eat without measuring, weighing, or preparing all my foods?
Thank you all for any input.
 
The best way to find out how your diet is and where the percentages are coming from is too keep a food log at www.fitday.com this will then tell you where you carbs/fat/protein are coming from. Hope this helps :)
 
%carb/prot/fat (long reply)

They figure it as a percent of calories, not weight or volume. Yes, they do math at every meal (that right there will take the pounds off!)

We eat the same things often enough so after a few days it's easy to look back for all the stats on, say, a half cup of cottage cheese or 5 ounces of beef.

Well, without measuring, there really is not much of a point.

Of course you have to measure your food but how else would you realize how big portions are? Very soon you will be able to eyeball it. For example, 3 ounces of meat is about the size of a regular deck of playing cards.

Successful nutritional fitness requires knowledge of how much one serving is, and how much *you* require. Many of us only kept food diaries less than 4 weeks. After that, the knowledge becomes part of you. If you find yourself straying you can always go back to it for a few days.

I found helpful a daily goal, calculated using my age, height, weight, my reasonable goal of how much fat I wanted to lose in how long, and how much activity I did each day. My trainer then divided the daily total by grams of each (pro, fat, carb) into 6 parts. I was to shoot for the one-sixth goal at each little meal. It was actually much more fun than I expected. And the results were fantastic!

I'm still working on it. You will be pleasantly surprised to find out just how much regular Cathe workouts jack up your requirement. It will take lots of experimenting to find what works for you.

If you want, you can download and print out a simple daily food diary page to fill out, in Excel, here: http://www.geocities.com/ciaobella98765/FoodDiary.xls

Fitday.com has all the grams/calories info, and it is also available in little books you can take with you through the day.

And finally, to face hidden emotional reasons we get the urge to eat when we're not hungry, I highly recommend the book Life is Hard, Food is Easy by Linda Spangle, RN MA.

Enjoy your endeavor!
 
RE: How do you figure % prot/carb/fat - CONFUSED

Okay, trying to increase my understanding of nutrition, I used 3 food labels. Based on the label's Fat & Carb grams and % dv listed I've calculated for a 2,000 calorie/day diet a person needs @63 Fat gr, 314 Carb grams and 50 Protein gr. Does this sound right or way off? I also figured 'my' needs based on The Zone(blocks and ratios - not referencing calories at all) method. With that calculation I came up with 33 Fat gr, 99 Carb gr and 77 Protein grams for me personally. Does anyone know why the big difference?

On a 2000 cal/day diet:

40% carb is 200 grams (2000*40%/4 cal per carb gram)
30% protein is 140 grams
30% fat is 67 grams (9 cal per fat gram)

When looking at food labels, subtract fiber grams from total carb grams as the fiber isn't used by the body for fuel since it passes on thru.

I think you're confused by the food labels because the RDA's & dietary guidelines are based 55/15/30 not 40/30/30. The 40/30/30 is a recommendation people are getting from popular diets.

The recommended daily allowance on food labels is not tailor made to you. So it's not going to be of much use. It is made for the average male who is sedentary and weighs (how much? 170?) and wants to maintain that weight.

Alcohol has 7 calories per gram (Just thought I'd throw that in there)
