1. Eat mostly whole foods
Whole foods look roughly as they did when grown or raised: meat, eggs, fish, fruit, vegetables, potatoes, rice, beans, milk, nuts. Ultra-processed foods are made from refined ingredients and additives you wouldn’t cook with at home.
In a 2019 NIH trial, 20 adults lived in a research ward for two weeks on each diet, with the same calories, sugar, fat, and fiber offered. On the ultra-processed diet, they ate about 500 more calories a day and gained weight. On the whole-food diet, they lost weight without trying.
Steadier blood sugar and a healthier weight both matter for inflammatory skin.
2. Eat whole fruit, not juice
Fruit sugar comes with fiber, water, and polyphenols (plant compounds) that slow its absorption. In three large, long-term U.S. studies, people who ate more whole fruit, especially blueberries, grapes, and apples, had a lower risk of type 2 diabetes. People who drank more fruit juice had a higher risk.
Pair fruit with meat, eggs, yogurt, or milk for a steadier meal. Swap packaged sweets for ripe mango, dates, or berries.
3. Make fresh meat your main protein
Protein keeps you full, protects muscle with age, and aids recovery from training. Meat, eggs, and fish are complete, easily absorbed sources.
Choose fresh over processed. The World Health Organization’s cancer agency classifies processed meat (bacon, ham, hot dogs, deli meats) as a cause of colorectal cancer, and red meat as a probable cause, mostly at high intakes.
- Build meals around fresh meat, eggs, or fish.
- Eat processed meat only occasionally.
- Don’t burn or char meat regularly.
- Eat fruit, vegetables, and beans for the fiber meat lacks.
4. Raw milk carries real infection risk
Raw (unpasteurized) milk can carry Listeria, E. coli, Salmonella, and Campylobacter. A U.S. outbreak analysis estimated that unpasteurized dairy causes about 840 times more illnesses and 45 times more hospitalizations than pasteurized dairy. In 2024, the FDA found H5N1 bird flu in raw milk from infected herds.
The claimed benefits are mostly unproven. Pasteurization barely changes nutrients. In a small Stanford trial, raw milk eased lactose intolerance no better than pasteurized milk.
These people should never drink raw milk:
- Anyone pregnant
- Babies and children
- Older adults
- Anyone with a weakened immune system, including people on biologics or other immune-suppressing medication for psoriasis, eczema, or other autoimmune conditions
Choose whole, grass-fed, pasteurized milk instead. Low-temperature (vat) pasteurized, non-homogenized milk tastes closest to farm milk. If you drink raw milk anyway, buy from a small farm that tests regularly, keep it cold, and drink it fresh.
5. Honey is still sugar
Honey is a whole food and a better sweetener than refined sugar, but your body still treats it as sugar. Treat a teaspoon or two a day as a sweetener, not a supplement.
Never give honey, raw or regular, to babies under 12 months. It can carry spores that cause infant botulism.
6. Skip supplements unless you have a reason
For healthy adults, the U.S. Preventive Services Task Force found in 2022 not enough evidence that multivitamins prevent heart disease or cancer. It recommended against beta-carotene and vitamin E supplements for that purpose.
Exceptions:
- A deficiency confirmed by blood work, such as low vitamin D, iron, or B12. Treat it, ideally with your clinician.
- Pregnancy or planning one. Folic acid is recommended to prevent neural tube defects (birth defects of the brain and spine).
- B12 for some older adults and for vegans.
- Anything your clinician prescribed. Don’t stop it without asking.
If unsure, get a basic blood panel first.
7. Have caffeine only before noon
Caffeine blocks adenosine, a chemical that builds up during the day and makes you sleepy. Its half-life (the time your body takes to clear half) averages about five hours. It’s longer for some people, such as during pregnancy or on certain medications. Half of a 3 p.m. coffee can still be in you at 8 p.m.
In a sleep-lab study, 400 mg of caffeine (about two to three cups of coffee) taken six hours before bed cut total sleep by about an hour. People didn’t always notice.
Water and daylight before coffee is fine, but evidence for delaying caffeine is thin. For an afternoon slump, walk outside, drink water, or nap briefly before 3 p.m.
8. Use your phone less
Endless feeds are built to hold your attention and crowd out sleep, movement, and conversation. In one randomized trial, college students who limited social media to about 30 minutes a day (10 minutes per app) for three weeks reported significantly less loneliness and depression than a control group.
- Set daily limits on your most-used apps.
- Turn off notifications you don’t need.
- Keep the phone out of reach at meals, workouts, and focused work.
- Switch the phone to grayscale in the evening. Color helps make feeds sticky.
9. Evenings: a book, warm light, and no phone in bed
Bright, blue-rich evening light holds back melatonin, the hormone that helps you fall asleep. Even ordinary room light before bed can delay and shorten melatonin release.
In a Harvard sleep-lab study, people who read on a light-emitting tablet before bed fell asleep later, had lower melatonin, and were sleepier the next morning than when they read a printed book.
- Charge your phone outside the bedroom or across the room. Use a cheap alarm clock.
- Read a paper book instead of scrolling.
- After sunset, turn off overhead lights and use one dim warm or red lamp. Warm and red light affect melatonin far less than bright white or blue light.
- Blue-light blocking glasses are optional; the evidence is mixed. They’re cheap and low-risk but don’t replace dim light and a phone-free bed.
During sleep, skin repairs, appetite resets, and stress hormones come down.
10. Lift weights two or three times a week
The World Health Organization recommends 150 to 300 minutes of moderate activity a week, plus muscle-strengthening on at least two days.
In a 2022 meta-analysis (a study that pools many studies), 30 to 60 minutes of strength training a week was linked to a 10 to 20% lower risk of death from any cause, heart disease, and cancer. Adding aerobic exercise was linked to a larger benefit.
Muscle is your biggest store for blood sugar, so lifting improves your insulin response. That helps energy, weight, and the metabolic risks linked to psoriasis.
- Do two or three full-body sessions a week: squat, hinge (like a deadlift), push, pull, carry.
- Start light. Add a little weight or one rep each week.
- Walk on the other days, ideally in daylight, which also helps sleep.
11. Work on something you care about
In a study of nearly 7,000 U.S. adults over 50, people with the strongest sense of purpose were much less likely to die during follow-up than those with the weakest, even after accounting for income, education, and health.
Don’t let work crowd out your health habits. Founders often trade sleep for output and pay later.
- Do your hardest work in the morning, when caffeine and focus peak.
- Block gym time like a meeting.
- Set a hard evening stop to protect sleep.
What a day looks like
- Morning: water, daylight, coffee, eggs or meat with fruit, hardest work.
- Noon: caffeine cutoff, whole-food lunch, short walk outside.
- Afternoon: gym or a long walk. Fruit with milk or yogurt if hungry.
- Evening: whole-food dinner, phone charging outside the bedroom, one warm lamp.
- Bed: a paper book, then lights out at the same time each night.
What to track
For two weeks, log your caffeine cutoff, phone-free evenings, gym days, sleep hours, and next-day energy, mood, skin, and digestion. These habits pay off a day or a week later. A short daily check-in makes delayed patterns easier to see.
When to see a clinician
- You’re pregnant, immunocompromised, or on biologics and considering raw milk
- You want to stop a prescribed supplement or medication
- You don’t know your vitamin D, iron, or B12 levels from recent blood work
- You have heart, joint, or blood pressure concerns and plan to start heavy lifting
- You still sleep poorly after weeks of better evening habits
- You have low mood or anxiety that lasts weeks (in the U.S., call or text 988 in a crisis)
