Alas, if your aim is to lose weight, you might as well ditch or modify the exercise app on your smart phone that promises you'd been done and dusted with your workout in 7 mins.
Here's why your 7 minutes exercise app won't make you lose weight
Glucose and other carbohydrates are the major sources of energy for the human body. When we consume sugars and carbs, we are increasing the available energy molecules that can be utilized for cellular respiration and adenosine triphosphate (ATP) production. But what happens when we have more sugar than we need at any given time? To accommodate excess sugar in the system, the human body often stores excess sugar in the form of glycogen.
The bloodstream can hold about an hour of glucose for energy. If glucose levels are maximized and all glycogen storage locations are full then the excess glucose is converted to fat by the liver and stored in adipose tissue or fat cells.
The glucose can be immediately utilized by the body or stored as glycogen in the muscles and liver. The muscles can store about 20 minutes of glycogen for energy.
During the first 15 minutes of aerobic activity, glycogen or sugar within the muscles is used for energy. Fat metabolism for energy doesn't occur until about 15 to 20 minutes after beginning aerobic activity. This is why it's important that aerobic duration be at least 30 minutes.
So except you are repeating the sequence, please don't expect much weightloss. However, if your aim is to maintain good heart and body health, please go ahead and have a quickie!
Till next time,
