Locusts Help Our Understanding Of Human Obesity
Narration And it’s not only locusts that exhibit this behaviour. Spiders, fish and a number of mammal species regulate their protein intake more strongly than their carbohydrate or fat intake.
So could this theory be applied to humans? Might we also overeat if we stick to diets with a low proportion of protein? A small study performed by Professor Simpson’s group suggests this could be true.

The level of high quality protein we eat seems to limit the amount of carbohydrate we (or at least insects) eat.
This may be one reason obesity is increasing in protein poor societies??
In Humans?

Mhmmm. Nothing is to blame except ourselves. The increasing number of obese people is for the most part, due to modern lifestyles.
People just need to get off their asses and excersise!

Have you really read this thread?
Yes what you say is
one reason.
But, for one example, when you put an obese woman into hospital and drastically,draconianically, clinically reduce her calorie level to about 1,000 a day then make her exercise and then she still puts on weight.
What is happening?
The doctors at first thought patients were smuggling in food. But when they checked this and talked to the women they found this was not happening.
The women patients complained that they were being fed twice as much as they would be normally eating in/at the hospital than at home.
Their systems were obviously
super efficient at extracting calories from food.
Why?
I don't think thee will be one simple answer.
Look at the
Hungerwinter "experiment" in the 1940s in this thread. These days we have skeletal, pre- pubesecent models of beauty in all the media. Do modern women starve themselves in the first 3-4 months of pregnancy so as not to look "fat" (
a relative fashion term, at best), or perhaps save on maternity clothes?
It would be fascinating to know this- because of its long term effects on the final weight of the baby/child/ adult.
In animals
Look at kangaroos they eat a much leaner diet than cows yet have a much greater uses of energy, Much more active than cows; able to run all day in extreme conditions. A cow would not survive on the scrubby native grasses they eat. Kangaroo faeces is about the size of a pea. Cow faeces is the size of a dinner plate. Kangaroos produce no methane; cows produces masses. Are the bacteria in kangaroo's stomachs much more efficient than the cows?
Someone here had a signature quote which went something like "science doesn't start with an "Eureka" moment more like a "That's funny" moment.
We need to get away from the "one meme fits all approach" to obesity and start to look at what has happened in just the last, mere ,10-15 years to humans.
I am just saying
the eat too much and not exercise idea does not fit
all the facts and I think
that "is funny/strange"
