WHY DO WE AGE?
As we age we lose 30% of our muscle mass¹. After the age of 30, we lose muscle at the rate of about half a pound a year3+4. Unfortunately, this also includes muscle mass from our vital organs. Even if we stay at the same body weight throughout our lifetime, fat replaces muscle tissue³. All of this may lead to cardiovascular problems, poor functioning of organs such as the liver, brain, heart and reduced hormonal secretion. As a result our bodies go from shapely to shapeless as we lose our strength, feel, look and become older.
WHY DO WE GET FAT?
Muscle loss not only causes all of these problems but also results in a lowered metabolism (the rate at which we burn food for energy). Research shows that a pound of muscle burns approximately 50 to 100 calories per day. Unfortunately, for every pound of muscle you lose, it becomes easier to gain fat even when your food intake remains the same, as you are now burning less calories for energy. On average over our lifetime, muscle loss slows down your metabolism by as much as 45%3+4 . Ultimately, you have unsightly, soft fat where you once had youthful, toned muscle.
