7Aging can slow down metabolism
When you get aged, the metabolic rate will gradually slow down, this effect occurs even when you have the same amount of muscle tissues and fat. In fact, this decline begins as young as age 20. This means when you are older, the burned calories will be fewer at rest. However, you can slow down or reverse this trend by doing more physical exercises to build more muscle groups and adopting a more balanced diet. [7]
