Playbook of 33 Habits Born of a Calcium Score of 266

In August 2015, at the age of 43, a coronary artery calcium scan ordered at his wife's insistence delivered a jolt: a score of 266, placing him in the 98th percentile for his age — arteries more calcified than those of 98 out of 100 men his age — in a body that played soccer every week and looked entirely fit from the outside.

"My cholesterol numbers, the one test everyone relies on, had been telling me all along that everything was okay. That scan rewired how I think about health. I stopped trusting how I looked and felt, and I started measuring," the author writes.

What followed was eleven years of self-experimentation: changes to what he ate, how he moved, how he slept and what he tested — all documented across 79 posts. When a reader compiled every habit from those posts into one list and asked which had actually stuck in daily life, the answer grew into The Playbook, released as blog post #80: a single booklet holding the 33 habits that survived, each graded by the strength of the evidence behind it.

Numbers First

The author shares his results to show what is possible, noting he is not genetically gifted: "I am a Pune boy with a calcium score of 266 and the classic South Asian cardiovascular risk profile that Western risk calculators keep missing. If these numbers moved for me, they can move for you."

Grading the Habits

Compiling eleven years of advice revealed two truths: repetition — "the post-meal walk showed up in four different posts wearing four different outfits" — and, more uncomfortably, that not everything once believed held up equally well. Every conclusion was checked against randomized controlled trials in larger populations.

Each habit made the cut in one of two ways: either strong studies validated it, or no study contradicted it. If research went against the conclusion, the habit was dropped; if the evidence was thinner than the confidence, the habit stayed in with plain-language caveats. Every habit now carries a tag: Strong means large human trials, meta-analyses or clinical guidelines agree with the results; Moderate means good human evidence with real gaps, stated plainly. Of the 33 habits, 30 earned the strong tag and 3 sit at moderate.

Several habits earned their strong tag only after the claim was narrowed — like seasoning a dish. "The broad claim, that spices prevent disease, does not hold up. The narrow claim, that cooking with spices lets you cut oil, salt, and sugar without the food getting sad, or that black pepper multiplies turmeric absorption twenty-fold, absolutely does." Similarly, cold water showers lack strong evidence for longevity benefits but sharply increase alertness.

Some experiments failed entirely. A 72-hour fast "showed nothing that a simple 24-hour fast did not already give me" — and it negatively impacted muscle mass, so it was cut. "Does that mean it isn't worth doing? No, just that it didn't work for me and is worth judging for yourself with a clear marker or outcome in mind."

Notes highlight where advice changes for women, for perimenopause and menopause, and for South Asians. One crucial caveat: absence of evidence is not evidence of absence — some omissions exist because studies have not been done, not because studies proved the practices false.

The 33 Habits

Eat

Build meals the Mediterranean way: vegetables, legumes, olive oil, fish
Vegetables first, dessert last
Eat 25 to 38 grams of fiber a day
Replace saturated fats like butter and ghee with unsaturated fats like olive oil
High triglycerides? Cut sugar and alcohol first
Eat on your body's clock: finish dinner about 3 hours before bed
A 24-hour fast, once or twice a month
Read the nutrition label on protein and energy bars; watch dressings for added sugar
Make ultra-processed food the exception, not the routine
Check hydration by urine color; spread water through the day

Move

Walk after every meal
Strength train two to three times a week
Build your cardio base with Zone 2: easy sessions where you can still hold a conversation
Move through the whole day: 7,000 well-spread steps beat 10,000 with hours of sitting
More is not always better: know when more exercise starts hurting you

Sleep

Set up bedroom and evening for sleep: light dinner, cool dark room, no screens
Keep your bedtime inside the same one-hour window, every night
For 2 AM wake-ups: slow the breath, lengthen the exhale
Sauna, 20 minutes at ~170°F (75°C), three or more times a week

Breathe

Breathe through your nose, not your mouth; hum while you're at it
Practice five to ten minutes of slow belly breathing a day

Gut

Feed your gut bacteria with fiber from food; skip routine probiotic pills

Protein

Eat 1.2 to 1.6 g of protein per kg of your goal body weight, spread across your meals
Choose your protein source to close your gaps: whey is the best-tested; plant powders need bigger doses

Supplements

Put every supplement through a four-question test before you buy it
Take 5 g of creatine monohydrate a day
Take vitamin D3 and B12, but only if a test shows you're low
Omega-3: eat fish first; ask about prescription EPA if your triglycerides stay high
Buy only third-party tested supplements; the industry is barely regulated

Test

Get a coronary calcium scan, the 10-minute heart test
Test Lp(a), the genetic heart-risk marker, once in your life
Ask for three extra blood tests: ApoB, fasting insulin, and non-HDL cholesterol
Measure your visceral fat and muscle mass with a body scan, not just your weight

The One Thing

If you do only one thing, make it the act that started everything: "If you are over 40, or have family history, or are South Asian, ask your doctor for a coronary calcium scan and a once-in-a-lifetime Lp(a) test, and start measuring your ApoB (apolipoprotein B) regularly. My 266 calcium score was found because I asked for a test nobody had ordered. Every number in this post followed from that single act of asking."
