Hi Eric,
Thanks for sharing the data. Nice graph, by the way! From looking at the post-meal graph, we can still observe the delayed gastric emptying effect of vinegar, as illustrated by the delayed peak. However, as you mentioned, the data may suggest that apple cider vinegar (ACV) might not work as effectively for you, or other real-world variables (such as cortisols and other hormones) could be influencing the results. Perhaps you were stressed about drinking the vinegar
Additionally, you seem to have a double peak response (biphasic), which is often considered indicative of good insulin sensitivity. This biphasic response can imply that your body is effectively managing blood sugar levels by releasing insulin in two phases—first, a rapid release to handle the initial surge of glucose, and second, a slower, sustained release to manage the remaining glucose.
Did you notice any differences in satiety with or without vinegar? Understanding your subjective feeling of fullness can help determine whether ACV has an impact on your appetite and overall food intake.
