John's doctor supervised 90 day water fast. Real bloodwork, daily videos, nothing staged.https://the90dayfast.com/https://the90dayfast.com/day/47/https://the90dayfast.com/day/47/Morning weight 178.3 lbs. John's daily note from day 47 of his doctor supervised 90 day water fast.Wed, 16 Sep 2026 00:00:00 GMThttps://the90dayfast.com/blog/day-47-still-in-ketosis-on-broth/https://the90dayfast.com/blog/day-47-still-in-ketosis-on-broth/Day 47 of the 90 day water fast and the first full day after John ended the water only run. He weighed 178.3 pounds this morning, down 0.1 pound overnight and 50.3 pounds below his 228.6 start on August 1. Two days of homemade beef broth have settled his stomach and the nausea that ended the fast is gone. The surprise is the ketone strip. It still reads 16, the top of the scale. He has added unsweetened cranberry juice diluted in water and the weight loss has slowed.Wed, 16 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/46/https://the90dayfast.com/day/46/Morning weight 178.4 lbs.

John weighed 178.4 pounds this morning, a 0.1 pound gain overnight and 50.2 pounds below his 228.6 start on August 1. A sudden episode of nausea on the afternoon of day 45 turned into vomiting that rest and water could not stop. He broke the fast at 10 PM with homemade beef broth and today he ended the fast on camera. Next comes refeeding, broths first, with his doctor in the loop.Tue, 15 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/45/https://the90dayfast.com/day/45/Morning weight 178.3 lbs.

John weighed 178.3 pounds, down 1.5 from yesterday and 50.3 pounds below the 228.6 he started at on August 1. Forty five days done and forty five to go, the exact middle of the fast. He said on camera he cannot believe he has lost 50 pounds. The day's practical story is gas from a growling stomach and the water schedule he built to quiet it.Mon, 14 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/44/https://the90dayfast.com/day/44/Morning weight 179.8 lbs.

John weighed 179.8 pounds, down 0.9 from yesterday and 48.8 pounds below the 228.6 he started at on August 1. The scale opened with a milestone. He is under 180 for the first time in over 20 years by his own reckoning. Then he answered two is this normal questions from six weeks without food. A stomach that growls at the quiet parts of the evening. And feeling cold in his arms and legs when he gets into bed.Sun, 13 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/43/https://the90dayfast.com/day/43/Morning weight 180.7 lbs.

John weighed 180.7 pounds, down 0.9 from yesterday and 47.9 pounds below the 228.6 he started at on August 1. A question from his DMs asked whether he is fasting for religious reasons. His answer covers the whole why in ninety seconds. Not religion, even though he is religious. Not weight loss, even though 47.9 pounds is gone. He is doing it to give his cells quiet time to rejuvenate. And the extra large shirt he films in is about to become too big to keep.Sat, 12 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/42/https://the90dayfast.com/day/42/Morning weight 181.6 lbs.

John weighed 181.6 pounds, down 0.9 from yesterday and 47 pounds below the 228.6 he started at on August 1. Six weeks in, he spent the update on a decision. He felt sluggish, took electrolytes two days running and his stomach got queasier with every dose. So he connected the dots on camera and quit them. His reason fits in one line. You gotta listen to your body.Fri, 11 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/41/https://the90dayfast.com/day/41/Morning weight 182.5 lbs.

John weighed 182.5 pounds, down 1.8 from yesterday and 46.1 pounds below the 228.6 he started at on August 1. He took a client to lunch and sat across from a steak salad while drinking water. She offered him a piece. He said no. Then he drew the line that makes the whole day worth reading, which is that he is not hungry. He just wants to eat.Thu, 10 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/40/https://the90dayfast.com/day/40/Morning weight 184.3 lbs. John's daily note from day 40 of his doctor supervised 90 day water fast.Wed, 09 Sep 2026 00:00:00 GMThttps://the90dayfast.com/blog/day-40-at-what-point-do-i-stop/https://the90dayfast.com/blog/day-40-at-what-point-do-i-stop/Day 40 of the 90 day water fast. John weighed 184.3 pounds, down 0.6 from yesterday and 44.3 pounds below the 228.6 he started at on August 1. He is not stopping today. He spent the whole update on the question he has not answered yet, which is what number he should stop on. He did the arithmetic out loud on the water weight that comes back afterwards. Then he handed the question to the people watching.Wed, 09 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/39/https://the90dayfast.com/day/39/Morning weight 184.9 lbs. John's daily note from day 39 of his doctor supervised 90 day water fast.Tue, 08 Sep 2026 00:00:00 GMThttps://the90dayfast.com/blog/day-39-the-shape-of-a-pear/https://the90dayfast.com/blog/day-39-the-shape-of-a-pear/Day 39 of the 90 day water fast. John weighed 184.9 pounds, down 1.1 from yesterday and 43.7 pounds below the 228.6 start. His ketone strip hit 16 mmol/L, the top square on the chart, after reading 4.0 the morning before. Then he stood in front of a mirror over the holiday weekend and worked out that his top half is shrinking faster than his bottom half.Tue, 08 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/38/https://the90dayfast.com/day/38/Morning weight 186 lbs. John's daily note from day 38 of his doctor supervised 90 day water fast.Mon, 07 Sep 2026 00:00:00 GMThttps://the90dayfast.com/blog/day-38-same-weight-in-half-the-time/https://the90dayfast.com/blog/day-38-same-weight-in-half-the-time/Day 38 of the 90 day water fast. John weighed 186.0 pounds, down 1.3 from yesterday and 42.6 pounds below the 228.6 start. The ketone strip jumped again to 4.0 mmol/L, the fourth square on the chart. Then he did the math out loud. The last time he reached this weight it took him 83 days and this time it took 38. He gave two reasons for the gap and one of them was the avocado.Mon, 07 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/37/https://the90dayfast.com/day/37/Morning weight 187.3 lbs. John's daily note from day 37 of his doctor supervised 90 day water fast.Sun, 06 Sep 2026 00:00:00 GMThttps://the90dayfast.com/blog/day-37-turning-on-fat-burning/https://the90dayfast.com/blog/day-37-turning-on-fat-burning/Day 37 of the 90 day water fast. John weighed 187.3 pounds, down 2.9 from yesterday and 41.3 pounds below the 228.6 start. It is his biggest single morning drop since day 3, five weeks ago. His explanation is that his body finally let go of water it had been holding since the avocado incident. The ketone strip backed him up and climbed from 0.5 to 1.5 mmol/L overnight.Sun, 06 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/36/https://the90dayfast.com/day/36/Morning weight 190.2 lbs.

John weighed 190.2 pounds, down 0.7 from yesterday and 38.4 pounds below the 228.6 start. Six days after the avocado incident the ketone strip finally shows a trace and he logged 0.5 mmol/L. He also explains why the videos changed their wording. Some social platforms have been restricting the content, so the script talks around certain words now.Sat, 05 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/35/https://the90dayfast.com/day/35/Morning weight 190.9 lbs. John's daily note from day 35 of his doctor supervised 90 day water fast.Fri, 04 Sep 2026 00:00:00 GMThttps://the90dayfast.com/blog/day-35-the-metallic-taste-is-back/https://the90dayfast.com/blog/day-35-the-metallic-taste-is-back/Day 35 of the 90 day water fast. John weighed 190.9 pounds, down 0.4 from yesterday and 37.7 pounds below the 228.6 start. The ketone strip stayed blank again, though he swears it looked almost pinkish. The metallic taste in his mouth is back and people keep asking about it. So he walks through his three step routine for clearing it, toothpaste, a baking soda paste and a rinse.Fri, 04 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/34/https://the90dayfast.com/day/34/Morning weight 191.3 lbs. John's daily note from day 34 of his doctor supervised 90 day water fast.Thu, 03 Sep 2026 00:00:00 GMThttps://the90dayfast.com/blog/day-34-four-inches-off-the-waist/https://the90dayfast.com/blog/day-34-four-inches-off-the-waist/Day 34 of the 90 day water fast. John weighed 191.3 pounds, down 0.7 from yesterday and 37.3 pounds below the 228.6 start. The ketone strip read zero for the third morning in a row and he is calling the loss mostly water until it turns. So today he measured the fast a different way. His waist went from about 40 inches to under 36, his ring slides on with no fight and his shoes fit again.Thu, 03 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/33/https://the90dayfast.com/day/33/Morning weight 192 lbs.

John weighed 192.0 pounds, down 0.6 from yesterday and 36.6 pounds below the 228.6 start. Three mornings after a bowl of broth and a quarter of an avocado the two day gain has stopped and he is losing again. The ketone strip still reads zero. He is waiting on the color the same way he waited in the first week.Wed, 02 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/32/https://the90dayfast.com/day/32/Morning weight 192.6 lbs.

John weighed 192.6 pounds, up 0.6 from yesterday and 36.0 pounds below the 228.6 start. Two mornings after a bowl of broth and a quarter of an avocado his strip reads zero for the first time since the opening week. He is back on water only, waiting for the color to return and not happy about the pause.Tue, 01 Sep 2026 00:00:00 GMThttps://the90dayfast.com/day/31/https://the90dayfast.com/day/31/Morning weight 192 lbs.

John weighed 192.0 pounds, up 1.8 from yesterday and still 36.6 pounds below the 228.6 start. His ketone strip fell from 16 down to 4 overnight. The cause was the small bowl of broth and the quarter of an avocado he ate on day 30. He named it the avocado and broth incident, went back to water only and mailed off his home blood kit.Mon, 31 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/30/https://the90dayfast.com/day/30/Morning weight 190.2 lbs.

One third of the journey is done. John marked it by cooking the vegetable broth he promised on day 28, his first taste of anything besides water in a month. He also drew blood at home with a kit he will mail in for a full panel of readings. He signed off with a raised glass and a happy Sunday.Sun, 30 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/29/https://the90dayfast.com/day/29/Morning weight 191.1 lbs.

John thinks he knows why. He put electrolytes and Celtic salt back into his routine yesterday after a three or four day break and his body is holding on to water while it balances out. The queasy stomach that prompted the break gets its explanation too. He signed off with a raised glass and a happy Saturday.Sat, 29 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/28/https://the90dayfast.com/day/28/Morning weight 191.1 lbs.

That is a full 28 days water fast, 4 weeks to the day since August 1. John feels good overall but his stomach is still queasy and he has a plan for it. This weekend he may introduce a small amount of vegetable broth from a recipe he worked up himself. He signed off with his usual raised glass and a happy Friday.Fri, 28 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/27/https://the90dayfast.com/day/27/Morning weight 192.6 lbs.

Today he opened his DMs and answered the questions people keep sending. What he actually drinks, why he skips exercise on purpose and why he walks the long way around anything that smells like fried chicken. Then he got to the part he calls the magic, autophagy, the reason a 56 year old man is doing this at all.Thu, 27 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/26/https://the90dayfast.com/day/26/Morning weight 193.5 lbs.

Two stories today. His stomach has turned into a burp machine and he is fine with it, because each one eases the pressure. And his sleep, the thing the fast broke around day 12, is now the best it has been in years. Here is what the burping is about, why it tends to show up on an empty stomach and what changed in his nights.Wed, 26 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/25/https://the90dayfast.com/day/25/Morning weight 194.8 lbs.

The story today is his stomach. The daily Celtic salt and electrolyte glass that fixed his sleep two weeks ago left him queasy, so he paused it, felt better by morning and is now testing an every other day rhythm. Here is what happened, what he is changing and the honest answers on electrolytes, sour stomachs and that metallic taste that will not leave.Tue, 25 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/24/https://the90dayfast.com/day/24/Morning weight 195.9 lbs.

Today's video came from his office, between paperwork and it was written by his DMs. A lot of people watching this fast have started 3 day water fasts of their own. Some are cruising. Some fell off on day one. Here is John's honest advice for the short fast crowd, plus the thing he says is actually the hard part and it is not the fasting.Mon, 24 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/23/https://the90dayfast.com/day/23/Morning weight 197 lbs.

And the number of the day is not on the scale. It is the BMI. John started this fast at 34.6, class one obese. This morning it reads 29.9 and for the first time in years the category says overweight instead of obese. Here is what the flip means, what it does not mean and why a Sunday of 10 hours of sleep might be the most underrated fasting tool there is.Sun, 23 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/22/https://the90dayfast.com/day/22/Morning weight 197.9 lbs.

The 30 pound line is crossed. The story today is a client lunch at a fried chicken place, a smell that walked right over him and an entire afternoon with one word on repeat. Here is what a craving actually looks like three weeks into a fast and what John did with it.Sat, 22 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/21/https://the90dayfast.com/day/21/Morning weight 199 lbs.

Day 21 of the 90 day water fast landed at 199.0 pounds, down 29.6 from the 228.6 start, which is 13 percent of John's body weight in 21 days. It is Friday and John opened with the weekend plan everybody else has, a burger, fries, maybe a drink, before catching himself. He also answered the question his DMs keep asking, what happened on his last fast. That one was unsupervised, 265 down to about 185. Here is where the body and the mind are after 21 days.Fri, 21 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/20/https://the90dayfast.com/day/20/Morning weight 199.7 lbs.

The scale read 199.7 pounds, down 28.9 from the 228.6 start, which is 12.6 percent of his body weight in 20 days. John has spent 20 years trying to get under 200 and says he has only managed it a handful of times. Today he also revealed his ultimate goal for the first time, 160 pounds. Here is what 20 days of water fasting actually looks like on the scale and why this number means more to him than any other so far.Thu, 20 Aug 2026 00:00:00 GMThttps://the90dayfast.com/day/19/https://the90dayfast.com/day/19/Morning weight 201 lbs.
