I don't understand weight loss

[TheDoctor]

David Attenboro' stated las week that 'generally' in Mammals about 80% of calories consumed are used to keep warm...
Can anybody qualify what I thought I heard?

So...if I needed to keep warmer, I'd burn more calories, and so lose weight?

On a Wednesday morning after my Tuesday evening pub session I'm sure I download more than 2lbs

Reminds me of a Peter Kay joke where he was taking the piss out of a Weight Watchers weigh in when the group was asked to applaud a 1lb loss by a member and Kay commented "a pound, A POUND, I sh;t more than a pound".

How do you mean qualify?

I mean, it's not so much the issue of temperature in terms of feeling a bit chilly, I gues, but the basic core heat that we have and reptiles don't, which is why they have to warm up in the sun just to function, whereas we can complain about feeling cold, but can still walk, talk and digest. I think that's what uses up the calories.

In Mammal's other than Humans I would guss that to be right, especially those that are in water.

your weight oscillates by at least two pounds during the course of a day!
if they say they "lost two pounds in a week" it might just mean they weighed themselves on monday in the evening just before bed, and on sunday just after they'd got up.

well for reasons i won't go into, i must weigh less than 5 minutes ago

A few years ago I went on a 'lemonade diet' and lost 10 kg in 10 days!

I meant, did I hear right, or is there a reference available that says whether the statement is true, whether it varies for different species or is it good for all mammals whether landlubbing, aquatic or human?

So to lose a pound a week I can eat the same and cycle for an hour extra each day?

So in a year I will be 52 pounds lighter?

Actually, I only need to lose two stone. SO I could stop sometime in September?
