@yalta that new study ‘suggests’ it doesn’t say definitively that being hungry is linked to ageing more slowly.
There are studies however that show that older people who are a bit heavier - not obese but with some weight on - actually fair better in old age than thin ones.
Anecdotally I have seen that in my family. Mostly as the bone thin ones eschewed food for smoking as they had done all their life to maintain societally approved thinness.
Those on here advocating restrictive eating and referring to anyone eating cake as ‘stuffing’ themselves and saying with certainty that being fat is a one way ticket to cancer and diabetes etc are as problematic as those critical of thinness. Every discussion on weight comes down to the same lazy insults - if you don’t enjoy food fine, but your language projects your own issues around it loud and clear and undermines any health claims.
Disordered eating, be that over or under eating is not good for anyone. The amount people need to eat to be healthy varies from person to person based on factors that can’t be assessed by a cursory glance or blanket judgement.
And holding thinness up as a barometer of health is just delusional - thin people get cancer and diabetes every day. Thin people who stay that way through under-eating also develop things like osteoporosis at a higher rate.
Let alone people who smoke or use off label drugs to maintain a weight their body is not meant to be. People using ozempic to suppress their appetite and buying it off unlicensed sellers online are at risk of gastroperisis (sorry awful spelling!) amongst other things - a condition that costs a huge amount to treat on NHS. Yet they would be held up as healthy by some on here simply because they are thin.
I am the heaviest I have ever been in my life yet I am also the healthiest - backed up by a recent full body check.
To some on here I would be considered average size, to others obese : what actually matters is health and that can be achieved at many sizes despite the absolute certainty of some to the contrary.
