This turns years of walking into something fun to picture. Walking is good for you on its own terms, and roast dinners are good on theirs. Food is fuel and pleasure, not something to earn or pay back. This is a curiosity, not a plan: your body uses energy all day, even asleep.
The working
15 km a week for 5 years, roast beef
A plate of roast beef, roast potatoes, Yorkshire pudding, carrots, peas and gravy comes to 677 kcal. A steady walk uses about 42 kcal a km on top of resting for someone of 73 kg, so 5 years at 15 km a week is 243 roasts, about 0.9 a week.

A reminder
Nothing here needs to be walked off. Your body uses energy all day, even asleep, and food is for fuel, pleasure and company. If food or exercise feel like a worry, talk to your GP.
