Why most health advice doesn’t stick

Hi ,

How are you doing today?

You have probably heard that it takes 21 days—or maybe 66 days—to form a new habit. Those numbers sound reassuring, but they are just myths. They don’t work in real life.


Or maybe you have been told that the key to changing your habits is extreme motivation and willpower. But motivation is unreliable, and willpower is a blunt tool.


We all know that we should eat better, move more, sleep well, avoid smoking, and drink less. But if we already know these things, why is it so hard to change or to maintain change once we have started?


The difference comes down to method. Most people don’t have a reliable way to create lasting change. The Tiny Habits® method is different. It’s a structured approach to behaviour change that:


  • Doesn’t rely on extreme motivation or willpower
  • Works by tapping into emotions
  • Helps you do what you already want to do
  • Helps you feel successful right from the start


Think about blood pressure. One of the first things people hear is “eat less salt.” That’s useful if processed food is a big part of your meals. But if you already cook from scratch, salt may not be your main factor. And not everyone has salt-sensitive hypertension. For some, the better pathway may be isometric exercises, adequate sleep, or higher potassium intake.


The outcome is the same—better blood pressure, but the pathways are different. My role is to help you discover your pathway and give you the tools to make it stick.


That’s exactly what I will be teaching in my upcoming program, Tiny Habits for Better Blood Pressure.

P.S. Even if your blood pressure is normal, you’re welcome to join. I’ll help you adapt the program to your own health goals.


Best regards,

Shabnam
