I’m a slim ( size 8-10 , not super skinny ) woman in my 50s and my partner, who is the same age, is obese. Because of our working patterns we don’t eat many meals together.
There is very little overlap between what he eats and what I eat. Our fridge is full of his food and my food.
He eats LOADS of carbs - toast and cereal for breakfast, sandwiches, crisps and biscuits for lunch, pasta, ready meals or pizza for dinner. He can eat a large cake in 2 days.
He SNACKS all the time . He’s convinced he will die if he feels even the slightest bit hungry for a few minutes. Most days he eats 3 Chocolate bars and every evening he has a whole packet of biscuits and at least one large bottle of coke/ Fanta.
If he wakes in the night, he will go down to the kitchen and eat cakes, biscuits, crisps and toast.
If the children have sweets or chocolate they know to hide it well or he will track it down and scoff it.
He eats no vegetables at all and only a little fruit, perhaps a few portions a week.
I eat LCHF, so lots of vegetables, a little fruit and a fair amount of protein. I never snack, drink fizzy juice, eat cereal, biscuits or cakes or ready meals.
The few things we do both eat, like cheese - he will have about 3 times the amount with half a packet of crackers and I will have a little with an apple or grapes.
For me, that’s a nice treat. For him, he’s done some sport of penance by eating a “healthily ” and he needs the reward of a chocolate bar or two.
When our working patterns were more similar I used to cook healthy dinners for him. He would complain about any vegetables on the plate, leave half of it of the meal saying he was full, and then scoff a packet of biscuits an hour later. It was soul destroying.
He simply doesn’t like most of what I enjoy eating, and vice versa. It’s NOT just quantity most of the time, we are like two completely different species.
