Calories from Macros
6

PeriComoToes · 23/06/2019 20:06

Is there a list/app that provides a breakdown of calories from carbs/protein/fat of a particular food item and not just grams?

Example. 100g of raw chicken breast according to My fitness Pal states:

110 calories of which 31g is protein, 0g carb and 1g fat.

It doesn't break it down further i.e. X amount of calories of 100g of chicken is from protein. You have to work it out yourself. Loosely it's g of protein X 4, g if carbs X 4 and g of fat X 9.

It's arduous working it out for every single food item

Surely there must be a pre done list? I can't find one. Is there one?

@PeriComoToes
Use Cronometer cronometer.com . Not only is it free, but it is so much better and more detailed than MFP. It even breaks it down to why protein you get.
The data comes from the NCCDB at the university of Minnesota, way more accurate than MFP and for your info 105gr uncooked chicken breast = 186 cal

Why do you need to know it in calories? For prepping I find it simpler to stick to grams

How do we know that it's more accurate? The general consensus, taking various sources into account, is that there are around 110 calories in 100g of uncooked chicken breast. What does the University of Minnesota know that the nutritional experts in the UK do not?

Where does your consensus come from?

From Healthline www.healthline.com/nutrition/calories-in-chicken#thigh
A 3.5-ounce (100-gram) serving of chicken breast provides 165 calories, 31 grams of protein and 3.6 grams of fat (1).
From the US department of Agriculture
fdc.nal.usda.gov/fdc-app.html#/food-details/171477/nutrients Energy 165 kcal

Even on MFP itself, people are doubting the accuracy. community.myfitnesspal.com/en/discussion/10714719/how-accurate-is-the-food-tracker

And the list goes on and on Newsflash: Many foods in the MyFitnessPal database are user-generated—so some aren’t accurate. For example, one medium apple can set you back 30 calories or 120, according to the options provided by the app. For foods you nosh frequently, check the nutrition facts online with the USDA food composition database.

MFP database is mostly user-generated and user confirmed. A user will put a food and its analysis, and other - as clueless - users will confirm the data .

SO if you are really into nutrition tracking use a nutrition tracking website or app that offers - usually for free - a detailed and scientifically proven, data.

Well, to name but a few:

  1. MFP — which has a large number of users. Where do your thoughts on 'clueless users' come from?

  2. Tesco — nutritional value on the packet

  3. nutrionix

  4. fatsecret

  5. nutrition table

  6. The National Chicken Council — they really should know.

    All of the above suggest between 100 and 120 calories.

    Granted, it's not a large sample size but it's larger than US Department of Agriculture in isolation, which I see no good reason to trust over other sources.
