I ate nothing but sardines for 21 days and tracked everything. In this video, I break down my full 21 day sardine fast results, including weight loss, ketones, glucose, bloodwork, OmegaCheck, DEXA, and what actually happened when I used sardines as a metabolic health tool.
Sardines are having a moment in the carnivore, keto, and metabolic health world, but I wanted real data. So I turned this into a full N=1 experiment using Keto-Mojo, CGM, SiBio continuous ketone monitoring, before and after bloodwork, OmegaCheck fatty acid testing, and DEXA body composition scans.
In this video I cover:
• why sardines are so nutrient-dense
• why sardines can be helpful for fat loss and ketosis
• mercury, arsenic, and heavy metal concerns
• how sardine fasting works
• my 21 day sardine fast weight loss results
• average glucose and ketone trends
• why my ketones went above 8
• why ketoacidosis was not a concern
• before and after bloodwork
• OmegaCheck changes in EPA, DHA, and omega-6 to omega-3 ratio
• DEXA fat mass, lean mass, and visceral fat results
• whether I would do a longer sardine fast again
This experiment taught me a lot about ketone management, appetite regulation, meal timing, and how quickly sardines can shift metabolism. If you are interested in carnivore diet results, keto results, sardine fasting, metabolic flexibility, blood sugar control, insulin sensitivity, continuous ketone monitoring, or N=1 biohacking experiments, this video is for you.
If you’ve ever wondered:
Can you lose weight eating only sardines?
Do sardines raise ketones?
What happens to blood sugar on a sardine fast?
Can ketones go too high on carnivore?
What does a 21 day sardine fast do to bloodwork?
This video answers all of that with real data.
