“Fat is carbohydrates and people who don’t eat fat get carbohydrate deficiency which causes obesity. You need lots of carbohydrates to stay healthy, so eat fat!” - old man in my office block

There's a kernel of truth here. Carbohydrates are most readily converted to fat when you have a calorie surplus, but I'm not a 100% this mess is try to say that.

It's so close to being true, like truth adjacent

Simplifying things a bunch, eating carbohydrates spikes insulin, which tells your body hey store this.

So if you eat carbohydrates and you eat fat you're getting a double whammy of store this fat.
