> .. don't know where you get the idea that eating 300g of meat is difficult.

You're right, 300 g of meat isn't much of a challenge. The more appropriate comparison would be between 300 g of chips and an equal amount of calories in some protein rich food like meat. That should be much more challenging.

> .. people today are eating too much.

Yeah, the important question is: why are they eating too much?

I assume that a lot of it is unintentional. Overeating mostly happens because people aren't aware of a few simple mechanisms or are misunderstanding them, not because the world is hard. Mechanisms which they could quite easily use to overeat less or avoid it altogether, instead of falling prey to them.

Just telling people that they're eating to much doesn't help in any way. People need to know why and how they can quite easily change it.
