People are paying hundreds, if not thousands of dollars for a d**g that mimics something your gut produces naturally when you eat enough soluble fiber. That is the takeaway from fitness coach Dan Go’s 28-day experiment with high-dose psyllium husk.
Psyllium husk is a soluble fiber derived from the seeds of the plantago ovata plant. Most people associate it with digestive health or constipation relief, but Go’s experiment pushed the dosage far beyond the typical single-tablespoon serving. He took two tablespoons three times a day, totaling six tablespoons daily, for 28 consecutive days.
The science behind the approach is straightforward. At therapeutic doses, psyllium husk absorbs water and forms a thick gel inside the gut. That gel slows gastric emptying, blunts blood sugar spikes after meals, and, most notably, triggers the release of satiety hormones, specifically GLP-1 and PYY.
These are the same hormones that Ozempic is designed to mimic through pharma means. Go is clear that psyllium husk is not Ozempic, but the underlying mechanism of blunting appetite through hormonal signaling is real, and research supports it.
The first week came with a learning curve. Go experienced bloating and low energy, which he traced back to not drinking enough water alongside the fiber. Once he corrected that, the discomfort faded within days. By the end of week one, his appetite had noticeably quieted.
“It was almost like the food noise had turned down because of how satiated I felt on a day-to-day basis,” he said.
He also made a costly mistake around day ten, taking psyllium husk right before a heavy dinner of roughly 300 grams (10.6 lbs) of fish. The result was severe bloating and cramping that lasted for hours.
“Not being able to walk and thinking what the f**k is happening with me right now,” he recalled. His AI nutrition app explained that the fiber had rapidly pulled water into his gut, forming a thick gel under pressure alongside a dense protein load, a combination his body was not equipped to handle in that sequence. The lesson: take psyllium husk 45 minutes to an hour before meals, not immediately before sitting down to eat.
By the end of the 28 days, Go had dropped 4 lbs, reported more stable energy after meals, and saw his LDL cholesterol move in a favorable direction. When he stopped the protocol, it took two to three days for his normal hunger levels to return. That delay, he said, confirmed something real had been happening physiologically.
His recommended approach for anyone interested is to start with one tablespoon per day, let the gut adjust for a week, and then gradually build up, always with at least eight ounces of water per dose. Spread doses between meals, not right before them, and never dry scoop the powder.
