Food maths

[mudskipper]

We've all heard of foods which supposedly have a negative calorie impact - i.e. use more calories to digest than they give you.

But the opposite is true too.

To put on a pound of weight, you need to consume 3500 extra calories.

1lb of lard has 4091 calories, therefore, presumably, would cause you to put on a pound and a bit.

How can a food weigh more after digestion than before?

I'd always assumed what you weigh = what goes in - what comes out.

I've always thought it was 3600 calories to burn off a pound.

And there are about 800 calories / 100 grams for fat (Butter, lard, MF etc) = 3584 calories per pound.

So I'd question the website that gave you 4091 cals per pound.

Edit:- Anyway, if you are going to eat a pound of lard, make sure you have some greens as well :-)

I found it on the internet so it must be true.

All the 'nutrition information' websites seem to agree on 900 calories per 100g, but your figures make more sense.

What does the wrapper say - or have you eaten that as well?

Edit:- Interesting - Tesco agree with you at 900 cals /100g.

I don't know then - however, as a veggie, I'll not be testing it!

Edit Edit:- Ah, here we go, we are more watery when the lard is still a part of us!

Tesco Everyday Value Lard 250G - Groceries - Tesco Groceries

100g = 900 calories

1lb = 453.592 kg

900 * 4.53592 = 4082 calories.

Sainsbury's lard is "only" 891 calories.

Isn't the internet useful

I take these things with a pinch of salt.

Ah - makes sense. So it remains true eating a lb of lard will cause you to put on > 1lb of weight, because it presumably will absorb water that you would otherwise lose.

Still makes it celery's nemesis.
