We have landed in an era where food is measured in numbers. We plan our breakfast plate as 100 Kcal + 200 Kcal + 250 Kcal and not as a glass of milk, an egg and 2 pieces of toast with butter. The numbers will always add up to be the same, but there are unlimited ways to fill those numbers. So, instead of the above breakfast, you could have a glass of juice, a doughnut and a muffin OR a large bowl of yoghurt and mix cut fruits with honey. All these add up to a 500 calorie breakfast.
Let’s say you have been advised a 2000 calorie diet per day. And all you need to do in order to stay fit is eat within that limit.
