  • Eat to 3/4 full! And other tips from 1,000+ years ago (Maimonides)

    Eat to 3/4 full! And other tips from 1,000+ years ago (Maimonides)

    Chapter 4 of the ancient Jewish text Hilchot De’ot by Maimonides (AKA Rambam) has some surprisingly insightful recommendations for diet, rest, and overall health.

    Key Recommendations:

    Sleep:

    About 8 hours per night, ideally waking at dawn.
    This aligns with natural rhythms and ensures the body isn’t overtired.
    Sleep on your side, starting on the left and waking up on the right.
    Avoid sleeping face-down or immediately after eating.
    Moderation: Too little sleep weakens the body; too much dulls the mind.
    Rest is a tool to refresh, not an indulgence.

    Balance:

    Health is a state of equilibrium (balance).
    Our body shouldn’t be overburdened by excess or neglected by deprivation.
    Illness often stems from imbalance. Prevention is key.

    Eating:

    Moderation: Stop eating when your stomach is about 3/4 full.
    Never eat to stuffed/completely full. Leave “a quarter of the stomach empty”.
    Overeating leads to sluggishness and illness.
    Only eat when you’re hungry.
    Wait until food has digested before eating again (typically a few hours).
    Don’t rush eating or eat while distracted.
    Avoid excessive drinking during eating – it dilutes digestion.
    Drink moderately and increase fluids after digestion begins (the meal settles).
    Adjust diet based on climate: More warming foods (spices, hot/spicy foods) in cold weather. Lighter foods in hot weather.

    Mental State:

    Anger, stress, or sadness disrupt digestion and health.
    Rambam ties emotional well-being to physical care, urging calm and cheerfulness during meals and rest.
    A person should not eat with a heavy heart, nor when angry or afraid, but with a settled mind and joyful heart. So too, one should not eat immediately after exertion or hard work until he rests and calms down.
    Emotional well-being is tied to physical health.

    Hygene:

    Regular bathing and keeping the body clean to prevent disease. Washing hands, face, and body as needed.
    Live in a place with fresh air and avoid polluted or damp areas. Good ventilation and cleanliness are critical to avoiding sickness.
    Proper bowel and bladder habits are vital. Don’t delay urination or defecation when the urge arises, as holding it harms the body. Likewise, don’t force it unnaturally! Let the body regulate itself.

    Exercise:

    Moderate exercise before eating to stimulate digestion and maintain strength.
    Preventing Sluggishness: A body that’s never moved becomes weak and prone to illness. Regular movement keeps organs functioning and prevents blockages.

    Summary:

    Balance in Health:
    A person should aim for moderation in eating, drinking, and physical activity (not too much or too little) to keep the body in optimal condition.

    Dietary Guidelines:
    Rambam advises eating foods that are easily digestible, avoiding overeating, and consuming only what’s necessary to sustain health. He warns against eating until the stomach is overly full (stuffed). Eating to 3/4 full is enough to be satiated, especially if you minimize ultra-processed foods.

    Exercise and Rest:
    Moderate physical activity and proper sleep are encouraged, to maintain bodily equilibrium.

    Hygiene and Environment:
    Cleanliness, fresh air, and avoiding harmful conditions are essential to well-being.

    Moral Purpose:
    Rambam links physical care with the greater goal of achieving knowledge of G-d. Noting that a sick or weak body gets in the way of the mind’s ability to focus on higher pursuits. Making this advice not just practical, but ethical. A foundation of good health allows us to help others, be there for those we care about, fulfill our spiritual growth, carry out mitzvot (commandments), and pursue wisdom.

    Solomon said in his wisdom: “He who guards his mouth and tongue keeps his soul from troubles” (Proverbs 21:23). This refers to guarding the mouth from eating harmful foods or overindulging, and the tongue from speaking except what is necessary.

  • What are seed oils and why are they bad?

    What are seed oils and why are they bad?

    One of the most common questions I get is:

    “What are seed oils?”

    So first off, here’s a list of the most common seed oils:

    Canola (rapeseed) Oil
    Soybean Oil
    Corn Oil
    Sunflower Oil
    Safflower Oil
    Grapeseed Oil
    Cottonseed Oil
    Rice Bran Oil
    and any oil extracted with chemicals or heat:
    This includes any Olive Oil that isn’t Extra Virgin, and fake avocado oils.

    NOTE: Margarine is also made from seed oils, and to make it worse, they’re hydrogenated (trans-fat).

    Avoid margarine. This includes Earth Balance and anything labeled “Plant Butter.” Plants don’t make butter
    They’re trying to trick you into eating margarine by making it sound natural and healthy. Don’t be fooled! It’s bad for your health and your cardiovascular system. Very toxic and inflammatory.

    Why are seed oils bad for us?

    Several reasons.

    For one, they’re usually made from plants we don’t actually eat – OR that we don’t consume in anywhere near the quantities we’re getting in the oil.

    Take canola for example. What is a canola? Well, it’s actually a marketing spin to make you think it’s something else. It stands for Canada Oil Low Acid, and there’s actually no such thing as a canola plant. In truth, it’s rape seed oil. We don’t eat rape seeds and just because some marketers convinced the world this cheap oil was “heart healthy” doesn’t mean we should. Marketing claims aren’t fact. Even marketing like the American Heart Association seal should be questioned. It’s on mostly processed and unhealthy products.

    Hexane and chemical processing. The more processed, the further away from nature – that typically has a negative impact on our health. Not only are these oils heavily processed, they also use hexane (a toxic solvent) and other chemicals/solvents to make them.

    Seed oils are typically rancid. Part of the processing removes the scent so we can’t smell that it’s rancid. Rancid oil is very toxic and should be strictly avoided.

    You might notice some of the oils that made the list aren’t made from seeds. They’re still lumped into the “seed oils” group since they’re typically heated and chemically treated, processed with hexane, rancid, de-scented, etc.

    Plus, how often do you eat rape seeds, cotton seeds, or a big bucket full of corn or soybeans (what it takes to extract a small amount)? That alone should tell us it’s not something we’re naturally adapted to.

    So what oils SHOULD I use?

    For high-heat, it’s best to cook with animal fats.

    Primary animal fats are:

    Butter
    – Best if cultured, grass fed pastured/pasture-fed, and organic.
    – Not sure what to get? Kerrygold is a decent choice if you can’t find butter that’s cultured and organic. It’s widely available. Opt for the silver wrapper – it’s unsalted and you can add your own salt to taste.
    Grass-fed beef tallow
    Ghee (clarified butter)

    NOTE: Yes, these are high in saturated fat. We’ve been told saturated fat is bad for us or that it’ll “clog our arteries.” That’s actually not true. Saturated fats are part of a healthy animal-based diet.

    For baking, dressings, and everything else use these oils:

    Extra Virgin Olive Oil (make sure it’s not fake!)
    Unrefined Virgin Coconut Oil
    Avocado Oil (make sure it’s not fake! 82% in stores are fake or cut with seed oil!)

    How do I avoid FAKE oils?

    Believe it or not, most of the “healthy” oils we find in stores are either fake or cut with seed oils. It’s not well regulated and the chain of custody during import makes it difficult to crack down on. But it’s ok, there’s hope! Knowledge is power, and if you know what to look for, you can avoid the fake oils.

    Extra Virgin Olive Oil:

    I prefer oil from Italy or Greece. I order mine directly from an olive mill in Greece (Isle of Crete) that I personally visited. But if you can’t visit the olive mill and verify for yourself, here are some tips:

    Only buy Extra Virgin Olive Oil. Never “Virgin” or just “Olive Oil”, as these are extracted with heat and chemical solvents. Extra Virgin means it’s cold-pressed without any solvents or chemicals. Or at least it’s supposed to be (when it’s from a reputable source). So here’s how to further dig and avoid unhealthy fakes:

    Only buy single origin oil. This means that only one country is listed as the source on the label. If it says “Product of Italy” or Product of Greece” and not 2 or 3 countries, that’s single-origin.

    Here are some oils I found at Whole Foods and Traders Joes. Notice how these are not single-origin – so they likely contain seed oils as the chain of custody isn’t tightly controlled:

    Another bad Olive Oil:

    And here’s one from Trader Joe’s where they’re trying to trick you! Notice it says “Packed in Italy” but the sources are from elsewhere. Very sneaky and dishonest!

    And here’s what a legit single-origin olive oil looks like. This is the back of a Lucini Premium Select Extra Virgin Olive Oil.
    It’s single-origin (just Italy) and I would use it:

    Only buy oil in Glass Bottles! Plastic leaches petrochemicals into the product which are hormone disruptors, they also contain microplastics. Heads up: metal containers are usually lined with plastic – avoid them as well.

    Known-good brands:

    Lucini
    – Known-good last I checked and widely available.
    – Opt for the “Premium Select” version, not the “Everyday.”
    Anoskeli
    – Difficult to get in the US, but great stuff!

    Avocado Oil:

    Even most Avocado oils are fake. Yes, MOST of them (82% according to this UC Davis study). But you can get real Avocado oil. Here’s how:

    Look for a green color (not yellowish). Should smell grassy – like an avocado. Buy only known-good tested oils. These brands are known-good, real avocado oil:

    Known-good brands:

    Chosen
    Primal Kitchen

    Consumer Lab is also a great resource for finding tested brands.

    Summary

    I hope this helped answer the most common questions:

    “What are seed oils?”
    “What should I use?”
    “How do I avoid fake oils?”
    “What should I buy?”

  • How to NOT GET SICK

    How to NOT GET SICK

    Here’s how to avoid catching the common cold or whatever’s going around your office. And minimize how often you get sick.

    The body is always healing and good health is our default. Disease happens when something gets in the way of that default.

    The key breakthrough is taking daily Quercetin, Bromelian, and Zinc. But it’s important to note they rely on the healthy foundation habits below.
    If you compromise the foundation, the supplements won’t work as well.

    Breakthrough:

    Take Quercetin, Bromelain, and Zinc daily. These work like a virus shield – pretty amazing.

    Foundation Habits:

    Lay the foundation for optimum health with these habits:

    Get enough sleep:
    For most adults, we want to get at least 7 hours of sleep per night. Less then that makes us susceptible to getting sick, having hypertension (high blood pressure), and even developing some cancers.

    Minimize stress:
    Realize that stress doesn’t come from any outside situation, it’s actually our internal response. So we have a lot of control over stress and can retrain how we handle stressful situations most of the time. If we’re not paying attention we take shallow breaths. Instead, belly-breathe full breaths (through your nose). When you do stress, breath and workout. Check out my article on Dissolving Stress for more info and practical application. I also recommend Replace anxiety with relaxed vigilance (parasympatchetic activation) since this goes hand-in-hand with Stress response.

    Massage toxins out of feet regularly:
    Gravity helps circulate blood down to our feet, but it also interferes with the return flow so things tend to pool in our feet to some degree. If our cell drainage system gets stuck or backed up, disease forms. Even a quick 30-second foot rub moves the toxins and waste that accumulate out of your feet and into your circulatory system to be dealt with properly. I like to use a fascia scraper. Scrape the bottom of your feet from toes back towards your heel (encouraging flow in that direction).

    Get sunlight:
    We need much more sunlight than most of us are probably getting in modern society. Get outside regularly. Open windows and let light in – we need full spectrum light.

    Sunlight is good for our eye health and our body. LED light isn’t great. Natural sunlight is best (open the blinds, work near a window), but if you can’t work near a window use incandescent or full spectrum (Chromalux) bulbs and go outside for walks regularly.

    Take vitamins:
    They act like an insurance policy for key elements missing from our diet. Here’s my recommended stack.

    Minimize ultra processed foods and seed oils:
    Aim for at least 80% clean foods. What to eat.

    Don’t drink to excess:
    Alcohol impacts sleep quality and dehydrates you. This may go without saying, but avoid smoking and drugs as well.

    Positive mindset:
    This dovetails into minimizing stress, but worth noting the very real and measurable placebo effect. Our mindset and positivity have a measurable impact on our health.

    It’s critically important we realize the reverse is also true. The “nocebo effect” is defined as “a substance that causes undesirable side effects as a result of a patient’s perception that it is harmful rather than as a result of a causative ingredient.” This means that if you think you’re getting sick you can make yourself sick. Don’t let negative or cynical people influence you here – keep a healthy frame of mind and know your default is good health, especially if you’re following these tips.

    Try these out and let me know about how you’ve avoided the bug that’s going around the office (or kid’s school). How long are you going now without getting sick?

    If you do get sick, can you now pinpoint which of these caused it? Was it because you didn’t get enough sleep or stressed out? Knowledge is power (and health) 😊.

    In good health,

  • Vitamins I take (My Stack) 2025

    Vitamins I take (My Stack) 2025

    It’s a simple, yet significant discipline to start improving yourself, create order, and build the future. Taking vitamins daily is the “keystone habit” upon which all other health practices are built. 

    Daily Supplements:

    Adults: take daily with food. For optimal effectiveness, separate into 2 batches taken with 2 different meals (breakfast and lunch, for example).

    Mushrooms:

    Allergy and Spike Protein Support:

    • Quercetin 500-1000mg
    • Bromelain 2400GDU
    • Zinc 50mg

    See this HalcyonDB guide for details and recommendations: Allergy and Spike Protein Support.

    Tips

    “If you fail to plan you can plan to fail.”
    So set yourself up for success by preparing your vitamins a week or two in advance. Package your batches into snack bags or pill organizers so you can bring them with you. That way you always have them available with you during a meal or snack.

    I’m currently using these so I can take one compartment with each meal, two times a day. This 4-block lasts me 2 days (4 batches).

    These also work, if you prefer:

  • How to get rid of allergies, 100% naturally

    How to get rid of allergies, 100% naturally

    In the past I’ve taken Claritin. And it works, but I feel weird (almost hyper/tweaky) and too dried out from it. So for many years I took a spoonful of raw local honey daily. It works surprisingly well, but takes at least a week or two to really start to kick in.

    While I’d still recommend raw local honey (in your daily Matcha Latte), years ago I stumbled on Quercetin during the pandemic as an alternative to Ivermectin. I had omicron. It was pretty mild, but when I lost my sense of smell it worried me. So I figured I’d try a combination of Quercetin, Bromelain, and Zinc – and in less than 24 hours, my sense of smell was coming back! Pretty amazing result, so I started researching Quercetin. What else can it do? And I found out for most people it helps with seasonal allergies when taken daily.

    Building on that, coupling Quercetin with Zinc can be a powerful antiviral. And Bromelain helps with spike protein. In this age of potential spike protein viral shedding exposure – I take a combo of Quercetin, Bromelain, and Zinc – and I swear by it.

    Not only are my allergies minimal (works way better than honey), but I avoid getting sick even with significant exposure to people with cold, flu, and the ‘vid ;).

    Key benefits:

    • Prevents/minimizes seasonal allergies.
    • Works like a shield against the winter-season viruses.

    What to take:

    • Quercetin 500-1000mg
    • Bromelain 2400GDU
    • Zinc 50mg

    Take daily. Can take several weeks to kick in, so it’s best to take preventatively on a daily basis.
