Brief Summary:
Dietary fibers are generally not degraded by the endogenous digestive enzymes but rather by the complex ensemble of microorganisms that reside in the human gut 1 This ensemble collectively known as the human gut microbiome plays a key role in breaking down fermenting and ultimately converting such dietary fibers into a variety of beneficial metabolites including most notably short chain fatty acids SCFA These end products of fibers fermentation affect host metabolism immunity and physiology and have been implicated in multiple diseases including obesity metabolic syndrome diabetes and cardiovascular diseases
Intermediate fasting and in particular circadian intermediate fasting ie 16 hours of fasting followed by 8 hours of allowed eating has been shown to have positive associations with multiple health conditions as obesity diabetes mellitus cardiovascular disease cancers and neurologic disorders In this study we will try to answer open questions utilizing the long fasting period during the day to investigate the isolated effect of dietary fiber consumption uncovering the degradation effect but not the bulking effect on the microbiome and the host physiology and in particular its glucose response

Detailed Description:
During the 22 days of the study participants will wear a continuous glucose monitor fill a daily food diary and collect stool and oral samples which will be used for microbiota profiling Participants will be asked to carry out an intermediate fasting regime which will include 16 straight hours of fasting followed by 8 hours which the participants will be allowed to eat Drinking water is allowed throughout the fasting hours
The groups will consume 4 12 20 grams of the dietary fiber per day according to the group they were assigned to while not exceeding the total fiber consumption of 50 grams per day which is considered a high-fiber diet
