Recap: How to maintain new habits in the New Year | Tara Swart & Sarah Berry

Today we’re talking about habits. Every January, millions of us set ambitious goals for the year ahead. Maybe you want to eat better, move more, stress less. But by February, millions of those well-intended resolutions are already in the bin. So why is changing your habits so hard? Neuroscientist Dr

Topics Discussed

Episode Summary

Executive Summary: The episode explains why habit change is difficult and how to make it stick through small, repeatable steps. Dr. Tara Swart argues that habit formation depends on the size and complexity of the change, motivation, and intensity of practice—not a fixed number of days. The conversation emphasizes avoiding self-blame after setbacks and using clear goals, rewards, and gradual progression to retrain the brain.

Main Topics: Why habit change feels hard (Priority: 5/5): The discussion opens with the common pattern of New Year’s resolutions failing because people rely on enthusiasm rather than systems, and because the brain resists change when setbacks trigger all-or-nothing thinking. Habit formation is not fixed to one timeframe (Priority: 5/5): Dr. Swart explains that there is no universal number of days to form a habit; the timeline depends on what is being changed and how intensive the effort is. Setbacks, guilt, and self-compassion (Priority: 4/5): The speakers stress that one bad day or even a difficult week should not be interpreted as failure, because guilt can reinforce the very behavior someone wants to stop. Goals and motivation drive change (Priority: 5/5): Meaningful deadlines or concrete targets—such as a vacation or wedding—make behavior change more likely than vague intentions, especially when motivation is high. Micro-changes and brain conditioning (Priority: 5/5): The episode recommends breaking change into bite-sized steps and reinforcing small wins so the brain builds conditions for larger goals over time. Personal example of retraining habits (Priority: 4/5): A story about reducing sugar in tea shows how gradual reduction can lead to a new default habit, demonstrating the value of stepwise change rather than quitting cold turkey.

Key Arguments: Habit change is easier when framed as learning something new for the brain, not as an instant personality shift. There is no one-size-fits-all timetable for creating a habit; the timeframe depends on the nature of the change and the effort invested. A single indulgent day does not usually erase established habits, but a longer period can make relapse feel normalized. All-or-nothing thinking after a setback is counterproductive because it encourages people to give up entirely. Clear, tangible goals increase adherence far more than vague New Year’s intentions. Small actions such as earlier bedtimes, more steps, or healthier swaps create brain conditions that support bigger goals later. Positive reinforcement and rewards help make habit change sustainable and less miserable. Gradual reduction can be more effective than abrupt elimination for highly ingrained behaviors like sugar intake.

Data Points: Habit formation for a small food change: about 2 weeks - Dr. Swart says moving from a bar of chocolate to one square nightly could be created in roughly two weeks. Time for profound behavioral change: at least 9 months - She says improving emotional intelligence or intuition would take at least nine months. Neuroplasticity analogy: gestation period of a baby - Used to describe the time needed for a profound change, likening it to becoming a new person. Spanish-learning example: once a week for 6 months - Compared a structured language course with an unguided app approach to show the effect of intensity and practice. Wake-up call from a personal nutrition test: 20 years - Jonathan says he may have lived on sugar for the previous 20 years before discovering poor blood sugar control. Initial sugar reduction: from 2 sugars to 1 sugar - He describes first cutting tea from two sugars to one as a step toward eliminating sugar entirely. Daily sugar intake example: at least 6 teas a day, probably more - Used to illustrate how ingrained the sugar habit had become. Preparatory habit for wedding: at least 3 months - Tara describes sustained, non-negotiable effort before her wedding as a period of focused behavior change.

Pivotal Quotes: "there's actually two questions there" — Dr. Tara Swart: She begins by separating the question of habit disruption from the question of how long habits take to form. "if a food is too healthy to be enjoyed, it's just not healthy for you at all" — Dr. Tara Swart: She offers this as a guiding principle to keep eating enjoyable rather than punitive. "we don't want this one to seem like a sort of miserable and insurmountable task" — Dr. Tara Swart: She emphasizes reward, fun, and small wins as part of sustainable habit change.

Implications: Listeners should focus on gradual, realistic behavior changes, avoid self-punishment after slip-ups, and use meaningful goals plus small rewards to build durable habits. For health coaching and public messaging, this supports a shift from rigid resolutions to flexible, brain-based behavior design.
