Dr Karan Explores · The Habit Expert: You Need To Find Your “Keystone” Habits · 27 Jul 2026 podcast

Typically, you know, at the start of the year or start of a month, people want to make a change, whether that's quitting something negative, cleaning their diet, losing weight, starting a new regime, going to the gym.

I think, you know, gym memberships always spike in January and February and then they, you know, peter off throughout the rest of the year.

What is it about that

time, like you know, the beginning of something which allows someone psychologically to

actually start to make a change, whereas in in the middle of a month or in the middle of the year they wouldn't.

What what's changing purely because of the time of year?

I guess there's uh you know, that's a bit of a double edged sword where, you know, that is part of our psychol psychology where we're looking for something new and

This kind of you see a lot of people use that psychology to take almost like an all or nothing approach.

Uh, you know, if I bring it back to diet, for example, someone may be on a diet and, you know, they've eaten a donut, which is not part of their diet, and they feel, Oh, God, that donut has now ruined the day.

I'll start tomorrow as a fresh start, clean, and now this day's already ruined, whatever.

I'm just gonna ignore it and then eat

whatever junk I want for this day, because I know tomorrow I'm it's you know, clean slate again.

You know, and I see this time and time again with other things as well, where someone sets an arboreary target of, okay, I'm gonna hit ten thousand steps, and if I don't hit that ten thousand step, there's no point and whatever.

So I get I guess it's there is some detriment to having that all or nothing approach because even a small change, whether it's positive, is good and it's all cumulative, and one small negative should not, you know, kind of spoil what you're trying to build.

Yeah, I guess people wanna make sweeping changes, um, and really sort of take the biggest possible change they can make, which, you know, of often is insurmountable for someone who, you know, has never done that before and then the setback effect kicks in and then they're even worse than before where they're not even doing that.

And, you know, if we're all talking about walking, there's abundant data that even a thousand extra steps beyond your baseline improves

Mortality outcomes.

You know, and I think this kind of 10,000-step idea, if you look at all the data, there's a large meta-analysis done on daily step counts and what the health benefits were.

It looks like the optimal dose, if you want to reduce your or cause mortality and improve cardiovascular outcomes, it's around 7,000 to 8,000 steps.

So, you know, the curve flattens out around 7 to 8,000 steps for giving.
