  • 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.

  • The ZERO Gram Trans-Fat Scam

    The ZERO Gram Trans-Fat Scam

    You probably know trans fats are bad for our health, and we want to avoid or minimize them. They can raise our LDL (“bad”) cholesterol and lower our HDL (“good”) cholesterol, promote cancer and rapid aging, weaken our immune system, and negatively impact our cell membranes.

    Trans fats are mostly found in deep fried foods and “hydrogenated” vegetable oils. Hydrogenated generally means that through a chemical process hydrogen atoms were added to these oils to make them solid instead of liquid.

    In 2006, the FDA started requiring food manufacturers to list Trans Fat on the label, but a funny thing happened after that. I’ll bet you $50 you can’t find any foods with more than 0 grams of trans fats on the label!

    Here’s an example I just found last week:

    Now for fun, I like to look at the ingredients panel on these kind of things.
    Here’s what that looks like. Lot’s of ingredients we don’t want, but can you spot the trans-fat?

    We can see it’s made with hydrogenated soybean oil (a seed oil), so it most definitely has trans fat in it.

    But would you be surprised that the nutrition facts shows 0g of Trans Fat!?

    Ok so what’s going on here? Well, if the manufacturer can get the amount of trans fat down to under 500 miligrams (half a gram) per serving, they can legally label it as zero.

    So again we have to be our own advocate. Just because a food claims zero trans fat, doesn’t mean it’s true. And in some cases, they’re really trying to trick you – like this tub of Crisco:

    Terrible terrible stuff for you. They promote it as a cheap alternative to butter (pro-tip: butter tastes way better and is much healthier for you), and really try to trick you into thinking it’s a good choice by advertising:

    That it’s “ALL-VEGETABLE” – since that sounds healthy
    Has 50% LESS SATURATED FAT than butter – since we’ve been told (falsely) that saturated fat is bad and is going to give us a heart attack.
    And it’s got 0g TRANS FAT – when it’s actually chock-full of trans fats. Note the “per serving” – pretty tricky.

    How big is a serving?
    12 grams (1 Tablespoon). Very small.

    And what’s in it?

    Fully Hydrogenated Palm Oil. Along with Soybean oil (a seed oil), and things you wouldn’t normally eat: mono and diglycerides (emulsifiers – texture and increased shelf life) and TBHQ (chemical preservative limited by the FDA due to safety concerns including vision disturbances, liver enlargement, neurotoxic effects, convulsions, and paralysis).

    A few takeaways:

    Don’t take health advice from food packaging
    0g Trans Fat isn’t true – look for hydrogenated oils
    Reading food labels can be a fun hobby (your mileage may vary 😊)

  • 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?”

    More questions? Keep them coming.

  • 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:

  • What to eat

    What to eat

    Most of what we’ve been told is wrong. Here’s what to eat and what to avoid for optimal health:

    Eat

    • Grass fed Beef, Wild Fish (Salmon, Black Cod, Tuna), Eggs (with yolks!)
    • Full-fat dairy – butter, raw cheese, raw milk, raw kefir
    • Beef Tallow, Bone broth
    • Fruits
    • Healthy oils – Single-origin Extra Virgin Olive Oil (EVOO), Coconut Oil, Avocado oil (known good brand: Chosen)
    • Honey, Maple Syrup
    • Some vegetables – don’t overdo it, they have natural defense chemicals in them

    Don’t worry about fat. It’s an important and healthy macronutrient. Yes that includes Saturated fat – it’s good for you. What you’ve been told is wrong 😊.

    You don’t need grains, but if you enjoy them lean towards glyphosate-free sprouted grain bread (silver hills or ezekiel) or pasta/bread/pizza made from imported Italian or French flour – in moderation. The wheat plant in Europe is different from what we have in the US. It’s much healthier for us. The wheat plant we have in the US has been selected/modified for high-yield.
    Fun fact: People who have gluten intolerance can usually eat european flour without issue. That’s why. It’s a different plant.

    Another fun fact: People who have lactose intolerance can usually consume raw milk without issue. That’s because it’s not cooked (aka “pasteurized”), so it includes the living enzymes that help you digest lactose. Best to avoid Homogenization as well – as it changes the molecular structure of milk so the cream doesn’t separate out. It’s a high impact on health for the silly convenience of not having to shake it.

    Avoid

    Avoid seed oils! They’re very unhealthy. These include:

    • Canola (rapeseed) Oil
    • Soybean Oil
    • Corn Oil
    • Sunflower Oil
    • Safflower Oil
    • Grapeseed Oil
    • Cottonseed Oil
    • Ricebran Oil

    … and any oil extracted with chemicals or heat: including Olive Oil that isn’t Extra Virgin, and fake avocado oils.

    You might notice some of these are not made from seeds. They’re still lumped into the group since they’re heat and chemical treated, typically processed with hexane (a toxic solvent not safe for human consumption), the oil is often rancid (oxidized), and the scent is removed so you can’t tell. 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.

    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. Margarine is primarily seed oils, and hydrogenated oil (trans fat). Very toxic and inflammatory.

    Moderation and Sustainability

    Aim for 80% healthy and 20% or less everything else. This gives you some flexibility to eat what you like without stressing.

    Daily routine – example diet and meal ideas to maintain health:

    Fermented foods every day. ACV (Raw Unfiltered Apple Cider Vinegar), kimchi, Sauer kraut – real fermented

    Vitamin regimen 

    Green tea or matcha

    Evoo

    Grass fed Beef and wild fish

    Full fat dairy – grass fed butter – Pasteured cultured organic is best if you can find it. Otherwise kerrygold, cheese

    Raw milk – matcha latte

    Fruits and vegetables

    Ease into the day. Low stress. 

    Swish with coconut oil (aka oil pulling). Brush with nano Hydroxyapatite toothpaste

    Organic Sprouted bread – Silver Hills or Ezekiel. Or bread made from European wheat.

    Egg and raw cheddar sandwich on sprouted grain bread is a good choice.

    Organic Heirloom popcorn – popped stovetop in coconut oil, finish with garlic powder and sea salt.

    French toast: Use silver hills organic sprouted bread, eggs, vanilla extract, cinnamon. Cook in stainless steel pan with pastured butter, top with butter and maple syrup. Dust with Simply Organic Pumpkin Spice.

    Chomps or Country Archer Grass-Fed Beef Jerky makes a great snack

    L. Reuteri Yogurt (half a cup) with a splash of maple syrup

    Chosen or Primal Kitchen Avocado Oil Mayo – great for making egg salad, deviled eggs, and steak sandwiches.

    Safe Catch or Wild Planet Tuna – mix with Fairchild’s Apple Cider Vinegar and high quality Extra Virgin Olive oil. Sprinkle some “everything but the bagel” seasoning on it.

    Salad – tossed with some high quality (single origin) Extra Virgin Olive Oil and Fairchild’s Apple Cider Vinegar.
