Question

Approximately 7700 calories make up 1kilogram (kg) of body fat, that's 3500
calories per pound (lbs). One chocolate chip cookie is 100 calories.
Work out how much weight a person would gain over a year if they ate two cookies
a day over their recommended limit and didn't burn off the extra calories. Calculate
the answer in either kg or lbs.​

Answer:

They assume that changing either side of the equation by 3,500 kcal will result in a pound (lb) (7,700 kcal for 1 kg) of weight gained or lost, without considering how changing energy intake or expenditure changes the energy balance equation.
