8 Realistic Healthy Habits That Make a Huge Difference

KEYPOINTS

• 01

  Shop the perimeter of the grocery store

  Dr. Aditi Nerurkar, a Harvard physician and stress expert, tells patients to stay on the outer ring of the store. That's where the produce, dairy, whole grains and lean proteins are, while the center aisles in the US are mostly processed and ultra-processed foods. Fruits and vegetables, plus fermented foods like yogurt, kombucha and kefir, support what she calls the gut–brain connection.

• 02

  The Mediterranean diet is a way of life, not a diet

  She calls it the gold standard: mostly plants, fresh produce, minimally processed foods, whole grains, beans, nuts and olive oil, with less dairy and red meat. She is clear this isn't about living like a monk. Food is pleasure, and a slice of chocolate cake under stress is 'good for your soul.' The problem is when it becomes a nightly habit, like her patient's 11 p.m. cake that started to affect his cholesterol.

• 03

  Small swaps add up for the microbiome

  Rather than a lifestyle overhaul, she suggests a few forkfuls of sauerkraut on your lunch sandwich or an extra helping of vegetables at dinner. Adding prebiotics and probiotics bit by bit, even if not every meal, strengthens the microbiome over time.

• 04

  Lifestyle comes before supplements

  Patients bring her bags of supplements. She records them in the chart as she would medications, and she stresses that she believes in conventional medicine. But when someone sleeping four hours and drinking four to eight cups of coffee a day asks for the best burnout supplement, she answers that sleep is a therapeutic intervention: cut the caffeine and move a little. Mel adds that the bigger the problem, often the smaller the solution.

• 05

  You are never too old to change

  She invokes neuroplasticity, calling the brain a muscle that responds to outside input, and says she has had 80-year-old patients whose behavior changes made all the difference in their stress and burnout. She suggests 'parenting yourself' back to health with the basics you'd give a child: a bedtime, less screen time, good food and daily movement.

• 06

  Sitting is harmful in its own right

  Beyond the benefits of exercise, she says prolonged sitting itself raises anxiety, stress and burnout. The mechanisms aren't entirely clear; one idea is that you 'stew in your own emotions.' There's no set dose for how often to stand. After a two-hour meeting, get up instead of turning straight to Slack and email.

• 07

  Fake your commute so your brain can switch modes

  About 85% of employees favor hybrid work, but the old commute did a psychological job: it moved you out of home mode into work mode, and the brain 'loves compartments.' Her fix takes 2–5 minutes. Set up your workstation, get out of pajamas, walk outside, grab a coffee, review the day's meetings and to-dos, then come back and start. If you can, bookend the day the same way instead of rushing straight to daycare or dinner.

• 08

  Multitasking is task switching, so monotask with time blocks

  She says only about 2% of brains can truly multitask. For everyone else, constant switching weakens memory, productivity and the prefrontal cortex's ability to solve complex problems. Her workaround for four tasks in an hour: spend 5–15 minutes on each with short breaks between, so you make headway on all of them without the switching cost.

• 09

  Habits take about eight weeks, but you'll feel it sooner

  She gives people a solid three months because they may slip, but says many feel a difference within a week. She encourages a concrete goal framed around your future self, such as 'I want to sleep through the night.' Being fed up is valid motivation too. And because even positive change is a stressor, big overhauls backfire when you're already stressed.

• 10

  Chase eudaimonic happiness, not just hedonic

  Hedonic happiness, like Netflix binges, fancy cars and designer bags, is a real and needed 'Band-Aid.' But the hedonic treadmill pulls you back to a set point, as with lottery winners. Eudaimonic happiness, built on meaning, purpose and contentment, is the kind she says science links to cellular and genetic changes that hedonic pleasure doesn't produce.
