Let’s say caffeine for example: one can drink it after dinner and sleep well at night, while another cannot sleep if is drinking coffee after lunch. Your body and behaviour is complex, and it will determine how you respond to a new diet.

One research group from Israel tried to make a prediction based on one’s glycemic response ( the glycemic response to food is the effect of that food on the blood glucose levels). They found out that different people react very different towards identical food components. The 800 participants that their blood sugar measured every 5 minutes with a special device, and they also used and app to report what and when they ate, when they sleep and how long and when they exercise. In the end their stool samples were collected and their composition and activity of the gut microbiota was measured. After all the data was collected, they made an algorithm that could successfully predict the blood glucose response for the participants. This was also used to successfully predict the response of 100 new participants, so this algorithm can be used to predict…
