A registered dental hygienist names four 2026 favorites they use and recommend to patients: the Quip Rev oscillating toothbrush, GUM Professional Clean floss picks, Sensodyne Clinical Repair toothpaste and the Quip rechargeable cordless water flosser.

• What to do: Choose an affordable oscillating toothbrush, durable floss picks that do not fray and a sensitivity toothpaste with enamel remineralization, then add a water flosser if you want extra cleaning.
• Why it matters: Technique decides results. Guide an electric brush slowly from tooth to tooth and never scrub, and floss by hugging the tooth up and down on each side.
• How to apply it: Subscribe to brush head refills every 3 months, keep floss picks in your bag, car and desk, and start the water flosser on its gentle mode before moving to deep clean pressure.
• Tools: Quip Rev, GUM Professional Clean Floss Picks, Sensodyne Clinical Repair and the Quip water flosser.
• Risks: The Sensodyne version they use contains SLS, which can irritate some mouths. Check the label for an SLS-free option if you have irritation.
• Exceptions: Sensodyne costs more than some pastes, and the water flosser category is crowded, so compare options if budget matters.

A family physician with 22 years of practice says a keto carnivore diet, which they call a proper human diet, can heal down to the mitochondrial level and in many cases put severe mental health disorders into complete remission, based on patient stories rather than trials.

• What to do: If you live with anxiety, depression or brain fog, talk to your doctor and consider a time-limited trial of a keto carnivore diet built on meat, eggs and animal fat.
• Why it matters: The physician has seen patients on a handful of medications with side effects such as lost sexual desire, and reports hope returning once they changed how they ate.
• How to apply it: Eat the meat without buying supplements or products, note your mood, anxiety and mental clarity week by week, and do not change psychiatric medication without professional supervision.
• Metrics: Stories in the video include Todd, who describes symptoms gone in three weeks, and a person with schizophrenia discharged within a month or two after decades in an institution.
• Risks: These are testimonies, not controlled studies, so stopping prescribed medication on your own could be harmful.
• Exceptions: The approach is not only a weight loss diet, and people without a formal diagnosis but with constant fog and fatigue are also part of the picture.

An average American spends about 12.5 of their final years sick, disabled or in a nursing home, and this video blames chronic inflammation and chronic disease rather than age, which ten habits can push back.

• What to do: Pick one to three of the ten habits and start tonight: get labs, eat fat and animal protein first, cut sugar, grains and seed oils, lift something heavy two or three times a week and sleep at least 7 hours.
• Why it matters: Visceral fat is the most dangerous fat, and in a British Medical Journal study the weakest grip carried about one and two thirds the risk of death of the strongest grip.
• How to apply it: Measure your waist and height with a tape, take private photos every one to three months, fast 12 to 14 hours before blood tests, skip snacks, stand up and sit down every 10 to 15 minutes and raise the head of your bed.
• Metrics: Hemoglobin A1C, fasting insulin, triglycerides, HDL, hs-CRP, vitamin D 25, sex hormones, waist-to-height ratio, five timed floor rises and 10 seconds on each leg.
• Tools: A tailor's tape, light dumbbells, red bricks or 2 by 4 blocks under the bed legs and the Proper Human Diet community for accountability.
• Risks: Snacks of any kind, seed oils, alcohol and sugary breakfasts keep insulin and inflammation high.
• Exceptions: Some people do fine on 6.5 hours of sleep, and a first step can be as small as walking to the mailbox.

Fasting feeds Akkermansia, a gut bacterium that eats the intestinal mucus layer, and with no fiber or polyphenols competing for its attention it can overgrow and thin that lining, which fits a Swedish study of about 4,200 people linking high Akkermansia on a low fiber diet to higher type 2 diabetes odds.

• What to do: Stay in the Goldilocks zone. Pair fasting with polyphenol and resistant starch foods such as berries, apple peel and crucifers, and vary your foods instead of repeating the same ones every day.
• Why it matters: Biology follows a U shaped curve, so even a good thing like fasting can drift out of balance over time through accumulation, degradation, attenuation and compensation. Akkermansia is good in balance and harmful when it has only the gut lining to eat.
• How to apply it: Eat foraging style foods the day before a fast (berries, resistant starch, crucifers, lower protein), keep fasts shorter, and treat a small handful of berries during a fast as acceptable. Do not take probiotics daily as a rule. Consider a few weeks only after antibiotics.
• Metrics: About 20 types of mucin are produced in the body. Apple peel carries very long procyanidin chains of roughly 30,000 units. Count calories weekly if at all, not daily.
• Tools: Element 500 mg sodium cans, with 100 mg potassium and 30 mg magnesium, no sugar and no caffeine, sipped through a fast. A CGM and ketone monitor can show how small foods affect you.
• Risks: Repeated long fasts can trigger hyperphagia, a binge urge that grows with a big meal. Daily antioxidants may blunt useful signaling after exercise, and carnivore style diets can raise Akkermansia without fiber to balance it.
• Exceptions: Akkermansia works best when your levels are low. Older adults tend to have more Akkermansia but fewer Bifidobacteria, which can strain the immune system.

Bone mineral density predicts only about 70% of fracture risk because a two-dimensional DEXA misses bone shape, and lifting challenging loads can thicken the femoral neck cortex even when hip density barely changes.

• What to do: Do two strength sessions a week built on a squat, hinge, push, pull and carry, add balance moves and keep up daily activity such as walking, dancing or shoveling.
• Why it matters: Bone mass peaks in your 20s and about 5% of the skeleton is remodeled every year, so the goal after 65 is to hold on to bone and prevent falls.
• How to apply it: Use 8 to 12 repetitions, pick difficulty rather than maximum weight, try walking lunges and step-ups, and add a few sets of 10 to 12 small hops if your joints allow.
• Metrics: BMD explains about 70% of fracture risk, FRAX estimates 10 year fracture probability, and CTX and P1NP track bone resorption and formation.
• Tools: DEXA with 3D hip analysis, FRAX, a machine circuit for beginners, Function Health tests, Prolon and Momentous creatine appear in the episode.
• Risks: Calling an X-ray bone on bone can scare people away from exercise, and heavy loads with poor form raise injury risk for beginners.
• Exceptions: For someone using a walker with severe arthritis, the goal is function and fall prevention, not bone density.

Plaque biofilm that your toothbrush cannot reach hardens into tartar, and that step turns bleeding gums into periodontal disease, an infection that can destroy the bone holding your teeth in place.

• What to do: Clean between your teeth every day with floss, floss picks, interdental brushes or a water flosser. The method matters less than doing it.
• Why it matters: Gum disease is linked with heart disease, diabetes and chronic kidney disease. Diabetes and gum disease affect each other in both directions, so poor gums can make blood sugar harder to control.
• How to apply it: If you have not flossed consistently, start today, because there is always a point in starting. If your gums bleed, keep cleaning gently. Bleeding is usually a sign they need more consistent cleaning, not less.
• Metrics: The progression runs from plaque to gingivitis (red, swollen, tender, bleeding gums) to tartar, then to periodontal disease and, in advanced cases, tooth loss.
• Tools: String floss, floss picks, interdental brushes and water flossers all disrupt the biofilm between teeth.
• Risks: Tartar is hardened plaque attached to the tooth, and neither brushing nor flossing removes it. Only a dental professional can.
• Exceptions: Persistent bleeding can have other causes, so talk to your dental provider. If you have not had a professional cleaning in a while, book one, then restart your routine.

Sauerkraut is not a probiotic: a probiotic is a specific strain with a known genome and clinical or randomized trial evidence, while the live microbes in sauerkraut, kimchi or kombucha are just live microbes, and only some yogurt brands list strains backed by evidence.

• What to do: Pick supplements or yogurts that print the strain name, take them with food and swap products if you notice no change after a trial period. Eat varied fiber and a mix of ferments such as yogurt, kefir, sourdough, tempeh and sauerkraut.
• Why it matters: Strains of the same species can act oppositely (EHEC E. coli vs the harmless E. coli in your gut), and a 37 study review of fermented dairy found benefits for gut symptoms, serum TNF alpha and gut barrier function.
• How to apply it: Store probiotics cool, dry and away from oxygen. If you avoid dairy, use plant-based yogurt, water kefir or kvass, whose microbes also survive in the gut. Treat commercial stool tests as information, and talk to a doctor or dietitian about persistent symptoms.
• Metrics: 37 fermented dairy studies; kimchi vs cabbage over 3 weeks; fecal calprotectin for inflammation and zonulin for gut wall function.
• Tools: Strain labels and the US probiotic guideline; stool tests only to detect pathogens such as C. diff.
• Risks: Wrongly handled food can carry Clostridium botulinum, and washing produce does not remove all pathogens.
• Exceptions: Most microbes pass through rather than settle, so the benefit depends on regular intake.

Motivation does not arrive before action: the feeling follows it, so the fix is the 5 second rule, counting 5-4-3-2-1 and moving the instant you hit one, before your brain can talk you out of it.

• What to do: Answer "what do I want from now on?", pick one small action that a person with that life would take, and count backwards 5-4-3-2-1 to start it even if you do not feel like it.
• Why it matters: Hesitation lasts under 5 seconds before you talk yourself out of a choice, and a streak of 21 days is not a habit. The body keeps its capacity to change at any age, even for a person who has never lifted a weight.
• How to apply it: Put the phone and alarm across the room, lay out workout clothes, leave creatine and a protein shot on the counter, pre-pick the workout the night before and keep treats out of the house. Tie your goal to a personal reason, such as protected time for yourself.
• Metrics: Hyman went from 10 push-ups at 50 to about 75 push-ups and 15 pull-ups after starting to lift at 59; The Let Them Theory sold 11 million copies in 19 months.
• Tools: Function Health lab data, a pre-planned workout, an audiobook for walks, and the ABC model (apologize, back off, compliment) to influence others.
• Risks: Pressuring a loved one to lose weight or take medication triggers resistance. Talk to your doctor before starting hormone therapy or changing medication.
• Exceptions: For big decisions such as a contract or a marriage, stop and think. The 5 second rule is for everyday choices you already know are right.

Supplements work best as the third layer after behavior and nutrition, and the smartest move is to test one single ingredient formula at a time for about a week, because that is how you find the minimum effective dose and drop whatever does nothing for you.

• What to do: Answer three questions first: how well do you sleep, how good is your nutrition and what is your budget. With about $100 a month or more, start with a broad foundational formula (vitamins, minerals, digestive enzymes, probiotics, prebiotics, adaptogens).
• Why it matters: No supplement or drug can make up for poor sleep, light exposure, exercise and food for long. Ingredients also behave differently in different people, and the ideal dose for you may even be zero.
• How to apply it: For sleep, avoid caffeine after 2 p.m. and food in the last 2 hours. To fall asleep faster, try magnesium threonate or apigenin for one week each. For waking at night, consider 900 mg myo inositol. For focus, keep stimulants (caffeine) separate from neuromodulators (alpha GPC 300 to 600 mg, L tyrosine 500 to 1,000 mg).
• Metrics: Aim for more than 1 g of EPA a day from fish oil. Fadogia agrestis is around 600 mg a day, cycled 8 weeks on and 2 off, or 12 weeks on and 1 month off. Tongkat ali is around 200 to 600 mg a day, with blood work after 8 to 12 weeks. Protein is about 1 g per pound of body weight.
• Tools: Examine.com for ingredient forms, and a high quality omega 3 as the single most impactful supplement.
• Risks: Fadogia agrestis can be toxic to testicular cells at high doses, alpha yohimbine can cause strong anxiety, and melatonin doses are far above natural levels and may not keep you asleep.
• Exceptions: Skip theanine if intense dreams wake you at night. Women should expect some supplements to act differently across the menstrual cycle. Always check with a physician before changing any protocol.

You can keep doing hard things by switching between several drivers instead of relying on one, as ultra endurance swimmer Ross Edgley did over a 157 day swim around Great Britain, a 56 hour Yukon swim and 30 marathons in 30 days.

• What to do: Name your spokes before a hard task: because I said I would, fear of letting people down, love, anger, doing it for others, gratitude for what you can do and the absurd hero mindset.
• Why it matters: The anterior mid-cingulate cortex reportedly grows when you do hard things and shrinks when you avoid them, and one driver alone tends to fail during long, painful efforts.
• How to apply it: Focus on the next stroke or step instead of the clock, lower the stakes in your head when pressure builds, protect deep sleep and switch spokes when one fades.
• Metrics: Edgley swam almost 2,000 miles in about 157 days, 317 miles of the Yukon in 56 hours went 70 hours without sleep on the Yukon expedition and uses his pull-up one rep max as a strength reserve.
• Tools: Electrolytes, a glucose wearable, a temperature regulating mattress cover and a protein snack are mentioned as sponsor products, not as part of the model.
• Risks: Motives such as anger or ego can fuel you, but Edgley found records alone felt shallow and sleep loss can drain dopamine and serotonin.
• Exceptions: In ultra endurance an imperfect stroke is fine, while high stakes in precision tasks can overload the motor system and hurt performance.
