  1. sleep –> movement/steps –> sunshine –> whole food –> fasting / ketosis –> building muscle mass (strength training 3 to 4 times 30 minutes + protein intake + EAA + creatine)
    – Vitamin G
    – Sunlight
    – Activity that you enjoy & doesnt feel like exercise
    – Being present before (humming) and during meal
    – Rebounding / jumping

  2. Based on the video, here are 5 actionable, simple habits for better health and fat loss:

    1. The 3-hour kitchen closing rule: Stop eating at least 3 hours before bed to allow insulin levels to drop, which maximizes the body's natural overnight fat-burning window during deep delta sleep (09:27 – 10:13).

    2. Prioritize morning sunlight: Getting sunlight in the morning helps sync your hormones with your circadian rhythm and supports melatonin production for better sleep (15:38 – 15:42; 16:04 – 16:08).

    3. Increase protein intake: Aim for at least 30 grams of protein at every meal to activate muscle protein synthesis, which helps with satiety and supports building lean muscle mass (19:45 – 19:50; 22:20 – 23:18).

    4. Practice mindful eating: To reduce bloating caused by chronic stress, eat your meals in a calm environment, avoid multitasking with phones or TV, chew thoroughly, and practice gratitude before eating to activate your parasympathetic nervous system (24:30 – 25:09).

    5. Utilize 'Vitamin G' (Gratitude): Use the free biohack of gratitude to help lower cortisol levels and increase oxytocin production, which helps combat stress-related belly fat (26:06 – 26:25).

  3. I'm 57, 5"7 and 165 lb. Work physical job 51 to 53 hrs / week. Eat twice per day. First meal around 7:30 am (I get up at 2am to go to work) chicken or salmon with any of the following sweet potatoes, jasmine rice cooked with chicken broth, spaghetti squash, once I a while regular pasta. Always add black pepper and curcumin powder and also EVOO. 2nd meal around 2:30pm, arugula with baby kale, EVOO, tomatoes, avocado, blue cheese or parmesan cheese and protein (chicken or salmon, daily intake about 130gr) sometimes I had 1 or 2 soft boil eggs. Been eating like this for years. Sometimes I'm not hungry on my day off so I just don't eat. Yet I'm still 10lb over and can't get rid of it… 😢

  4. Nonsense upon nonsense upon nonsense.

    Ask your guest to do a dozen pullups, 40 pushups and a 100 squats.

    Oh right. He can't. Everything coming out of him is *word vomit*.

  5. My walking “weighted vest” is my giant cat 🤣🤣🤣 she follows me until I pick her up and must be held for several laps and wants down and then follows me until I pick her back up 🤣🤣🤣😻😻😻

  6. Fasting
    Milk thistle
    Valine glycine glutamine lysine Little nac niacin Mixed with spirulina for better bioavailability
    Potasium Chlorid/salt 90/10 After before meal to make the Food Basic and stable blood Sugar and blood pressure
    Astaxanthin
    Vitamin k 1/2
    Vitamin b Complex
    Zinc Beet Root

  7. Loved this conversation. It was disheartening however to hear if we are not leaving 3hrs before bed to ‘close the kitchen’ it makes big differences in a negative way . I can only make my workouts at 6:15pm in the evening (immediately after work) and am usually home by 7:45pm – 8pm so it’s nearly midnight if I eat and leave it 3 hrs before bed which is way too late . So what the best alternative here?
