Most common questions I get … 
1) “Doc, what BLOOD KETONE METER do you recommend?”
      ANSWER:  FORACARE: (Promo-code: Dr.Boz)
      It’s accurate and takes only ONE test-strip to get results. YES!!
2) “Doc, what can I have while fasting?”
    Salt + water are best.  
    Salt: (Promo code: DrBoz) Sounds weird but it’s strangely satisfying.
    Black coffee – I prefer cold brew coffee. 
    Fasting tea Pique Teas:

3) “Doc, how do you know if you’re eating the right fat?” 
     Measure Omega 3 Index. No doctor’s order needed.

  1. hahahahahaha! you made me laugh when you said "Doc what can I have while fasting? Well it's fasting not much" I want to thank you. I'm 70 and having a hard time getting into ketosis, but I know from past a fast helps. I've been dealing with a slight loss of memory and intermittent tinnitus. I believe ketones are the answer. Last November I did a 6 day water fast. My tinnitus was silent for 3 days! I wasn't aware of ketosis. Thank you so much!!!

  2. on hour 48 of a 92h fast. i cannot explain, but fasting does something to the soul too. got a problem? fasting might help you find the solution. it clears my mind and gives me strenght

  3. Thanks doc! Thats brillant!! But all true, Im a raw eater, just fruit and veg, never done any 6 weeks keto or whatever it is called.. Been from 24-270 hours long, I healed Raynauds syndrome on my toes. Btw keto is not the diet right? What does it mean keto-i hope not protein,just fat??Some called keto diet, there is none, keto… nes we produce in the body, as the doc hopefully you know, that the protein changes into glucose in our body.. Anyway I eat lots of fruit and vegs, for breakie 3 bananas and 6 apples, 2 pears, never had any issue with weight or insulin resistance, even though non stop on carbo.. But I can see you speak your heart, thank you!! ❤

  4. It’s not that difficult and you don’t need to eat the fats and supplements she recommends ! At 59 I was 315 lbs. I lost 105 lbs in just under 4 months. You just have to have determination to continue and it’s easy to do. I did it with a 36 hr fast drinking lots of water. World record fast is one year ! So I thought I’d just eat one can of black refried beans every day for a month to see how I feel because I rode a bicycle every other day and paddled a kayak on the weekends. Beans are great protein and super low calories. I was loosing weight so fast I added a can of green beans and bought a lb of sliced roast beef to snack on occasionally. For 4.5 months I ate a can of beans and one can green beans about 3 pm everyday and ate 1 slice of the beef around 5 or 6. That’s it and ate 4.5 months I went from 315 to 205 lbs and have kept it off 6 years eating properly. I’m 65. 3-16-26

  5. I’d love tips to maintain because I lost the weight and regained it and for me it’s not sustainable to fast all a days of my life. I have kids, a lot of stress…

  6. Sooo fasting when you have a very physical high stress job ain’t gonna be easy. I get light headed and feel like crap sometimes when trying it in the past. Bone broth no help either.. Have the nickname muscle stick too so I’m not just a fatass lol)

  7. 1. she overweight so im confused as to how her diet is the best 2. this does not work for millions of people who have issues processing fat or have lipidtocicity LOOK IT UP!! 3. Fasting is great but eating a bunch of fat HAS NEVER WORKED!! And dr boz in this video is a great example of this.

  8. This is the best schedule for fasting on the tube. So well explained. I will be doing a 2 or 3 day water fast – then doing Dr. Boz 72 hour sardine challenge. I will break the fast with bone broth and maybe some saurkraut or avocado and saurkraut or eggs and saurkraut. Protein source, probiotic, and a fat source like avocado (not hamburger too heavy) to break a fast. Make sure the bone broth has protein like kettle and fire (not the cheap stuff). Nothing heavy to break a fast it will be too hard on digestive system. Then an hour or so later i will gradually increase over a 2-6 hour period to a full meal. To prepare digestive system for food again.

  9. don't eat a "high fat meal" or else you will be extremely hungry during the fast
    just do high protein low carb, low fat before starting a fast.
    i lost 97 pounds fast, its healthy.
