Is the calorie breakdown feature working properly?
I just joined yesterday, and had a very carb heavy day, so it's right for yesterday. Today I had 50g carb (40g net carbs) and 30g protein for breakfast, yet it's still saying almost the same as yesterday- 19% calories from protein and 63% from carbs. That does not add up!

Does it work on a cumulative basis rather than a daily basis? If so, how can I change it to show a daily breakdown?

Thanks if anyone can help with this!

I don't know that I could help with the math without looking at your journal.

Here's how you'd do the math:
1gram fat = 9calories
1gram carbohydrate = 4calories
1gram protein = 4calories
SO
50*4 = 200 cal carbs
30*4 = 120 cal protein
total = 320 cal
120/320= 37.5% protein
200/320= 62.5% carbs

What about fat? Have you eaten any today? It does work on a daily basis, but were missing something. The percents in your post don't add up to 100. There are only 2 other types of calories: fat or alcohol Smile

Thanks for the answers!

There was a small amount of fat, too, I think about 5g. The numbers weren't adding up for me, though maybe that's because I'm looking at the protein and carbs as a perecntage of each other rather than total calories. It doesn't make any sense at all to me that my carb calories would be three times my protein calories.
I've eaten more now (late afternoon here in the UK), but it's still not adding up! My numbers now are Fat(g)10.49, Carbs(g) 69.24 (Net C(g)51.74), Prot(g)66.48, KCals 555. But the Calorie Breakdown graph is showing this-
Calorie Breakdown:
Carbohydrate (50%)
Fat (17%)
Protein (33%)

I can't see how just a couple of grams difference would make such a big difference in the perecentages- there should only be about ten calories in it! Actually, I think either the calorie count or the grams count showing in my food diary is wrong, because when I do the math it should be around 635 calories on those grams. Maybe I'm missing something?

Oh well. Maybe I should stop worrying about it and go back to my old calorie and protein "guesstimate" method. It's worked okay so far.
I've wasted too much time today trying to make sense of the numbers My Fat Secret is giving me!

But thanks to you both for taking the time to answer- I really appreciate it!

You are absolutely correct. I started doing the math and it doesn't come out right. The only thing I can think of is that an item in your food journal could have been incorrectly entered. Remember, users enter the nutritional info for a lot of these things. I have noticed MANY mistakes over the year and a half I've been on here.
