Experiment Results

In the sixth podcast episode of The Betterment Experiment, Rocketbook co-founders Joe and Jake breakdown their weeklong experiment with the extreme eating habit of Intermittent Fasting.

 "I feel stronger about my ability to control my habits in every direction because I was able to control my appetite...if I can do this, I can do anything. " - Joe (8:14)

As a reminder, last episode Jake and Joe argued about which extreme eating method they implement to take their self-discipline to the next level, and our listeners voted for Intermittent Fasting.

All week, they ignored their evolutionary instinct to eat for at least 16 hours a day. By the end of the week, they had each worked up to fasting for a full 24 hours. They each found that committing to not eating for major chunks of the day freed up time previously spent on cooking, eliminated the midday lethargy they typically felt, and improved their self-control in other aspects of their life. Jake explains why it’s the key to a minimalistic life, and Joe offers a cautionary tale about breaking a fast with a rib-eye steak, red wine, and crème brûlée.

After sharing their experiences, they suggest an app that helps keep track of your Intermittent Fasting schedule.



This episode, Joe and Jake pitch their extreme ways to change their brain.

“Successful people are generally more optimistic, and this is a way to build up gratitude and optimism in your life, so that will make you more successful.”- Jake (14:34)

Gratitude Journaling

This extreme way of changing your brain works like this: every night before bed, you make a list of five to ten things you’re grateful for. Your gratefulness doesn’t need to be insightful or deep, but can be as simple as appreciating your new haircut. Jake advocates for this extreme brain-changing method that’s become an internet craze because it will decrease stress before bed and start each day with a renewed sense of optimism. Joe agrees that Gratitude Journaling is worth trying, but is hung up on Jake’s change from savage viking to zen master since E03’s debate about Daily Meditation.


10 Ideas A Day

This extreme way of changing your brain works like this: every day make a list of 10 new ideas. As an entrepreneur these might be business ideas, as a chef they might be recipe ideas—the only criteria is that they’re 10 original ideas. Joe predicts that after 6 ideas, your brain will start struggling, and that’s when you begin flexing the creative muscle of your mind. After a week of experimenting with 10 Ideas A Day, Joe guarantees they will have been transformed into creative idea machines.


As always, you can vote on which life hack you want Joe and Jake to test out on themselves. Then, listen in to the next episode where they'll discuss their findings!

Intermittent fasting is the current fad, but not a good idea in the long run. From this article:

“Non-diet approaches to health and wellness, such as mindful and intuitive eating, are more effective long term and reduce the chances of developing an unhealthy relationship with food and your body. There are many reasons for this- but perhaps the most compelling is the fact that without an answer for long term weight loss, weight cycling (or yoyoing) occurs in up to 95 per cent of people which leads to poorer physical and mental health.”

A better and healthier approach would be Intuitive Eating: https://www.intuitiveeating.org/10-principles-of-intuitive-eating/
