It really isn't. Small sandwich + crisps + sugary soda or coffee >= 700 calories, which is around twice what someone sedentary needs for lunch unless they start their day with a decent run. Add a chocolate bar and you're over 800. Start with a bigger roll or a wrap instead of a small sandwich and you're over 900.

Basically what you're saying is "eating too much food is bad" which… well, obviously. If you are eating a large sandwich, crisps, a sugary drink, and a chocolate bar for lunch… isn't it obvious that's too much? Eat a regular-sized sandwich, some popcorn, and a banana – like all the people who went to the Pret next to my office did pretty frequently.

literally lethal for someone in their fifties.

This is quite funny. "Sandwich culture is lethal to the over-50s".
