Little efforts go a long way. Human behaviour is a function of learned habits, and as per neurological studies, it has been identified that it takes 21 days of repeated performance to make or break a habit. This theory has been tossed around, more so lately, for years, but the idea was likely brought up first in the late 1950s by a plastic surgeon named Dr Maxwell Maltz in his book, Psycho-Cybernetics. Maltz discovered that his patients needed three weeks of time to get used to the changes he would make to their bodies.

The rules are simple

“These 21-day challenges are usually a mix of a balanced diet, physical activities, and behavioural changes, because good health is always holistic. It means being both physically and mentally fit,” says INFS-certified nutrition and fitness coach, Shriyam Srivastava.

Scientific studies show that 21 days is a sufficient time period for new neural networks to take shape, hence, helping us build habits in various aspects. Srivastava believes that to turn it into a success, the challenges need to be uncomplicated and achievable in the first place. “Health experts need to keep in mind not to give challenges which are too difficult to achieve in the first go, because that would only demotivate a person even further. Give simple, achievable targets to kickstart the transformation process.”
