Right, so, this might just be me making a silly error, but I can’t seem to make the macros on huel add up mathematically…
1g of protein = 4 calories
1g of carbohydrates = 4 calories
1g of fat = 9 calories.
So if we calculated that metric with 100g of vanilla huel…
Carbs 37.1g = 148.4 calories
Protein 29.5g = 118 calories
Fat 13.1g = 117.9 calories
148.4 + 118 + 117.9 = 384.9 calories per 100g of huel… Not 400 calories
So which is it? 
Add fiber to your calculations and let us know the result 
Ah, got it, I’m just being retarded.
Seems fibre is sometimes calculated at 2 calories per gram, from my understanding that its due to gut bacteria produced etc.
So if its 7.9 x 2 = 15.8
So all in all comes to 400.7 calories. Which makes sense. 
Don’t do that to us. Not cool.
But without the setup there’s no punchline & you did deliver it with not only aplomb but also a shiny gif? Thank you for the gift of laughter Tim; though I do hope it’s listed in the Huel Forum nutritional information & is less than the acute reference dose!
Also worth bearing in mind that the 4/4/9 calories for carbs/proteins/fats is a very good but not perfect rule. For example, proteins are made up of various different amino acids, and these amino acids don’t all have a perfect 4 calories per gram - there is some variance, with, for example, leucine and isoleucine having ~4.65 calories per gram and valine having ~4.64 calories per gram amongst other differences. Medium chain triglycerides (MCTs) also have a lower calorie content than most other fats, having ~8.3 calories per gram rather than the traditional 9 calories per gram. So if you see a label where the calculation doesn’t quite work out perfectly, that doesn’t mean the label is wrong.
Can I use you and this comment as a reference in my CV? Or perhaps I’ll add it to my eHarmony profile…
Correct and I use these in my own formula calculations; however, our labelling is validated by testing and in testing, they use the 9,4,4,2 rules.
Also note, the calories per gram calculations vary in different parts of the world… yes, I know …
Do you happen to have a source with the calories per gram of each amino acid? I’ve been looking for a while but can only find the data for the BCAAs.
No, but I can ask someone …
I’m sure you’ve been non stop thinking about this for the past year - but don’t fret. I wrote an article about it …
Hi Rebeca - thanks very much for this. I did actually find the data a little while after I posted last year (seemingly from the same source study as used in your article), but it’s great to see this information made more easily available. Thanks for letting me know
