However, a more extended daily fast poses many challenges. This study was designed to evaluate the effects of a 200-calorie fasting-mimicking diet (FMD) energy bar formulated to prolong ketogenesis and mitigate fasting-associated side effects. A randomized, controlled study was conducted comparing the impact of consuming an FMD bar vs. continued water fast, after a 15-h overnight fast. Subjects in the FMD group showed a 3-h postprandial beta-hydroxybutyrate (BHB) level and 4-h postprandial BHB area under the curve (AUC0\u20134) that were non-inferior to those who continued with the water fast (p = 0.891 and p = 0.377, respectively). The postprandial glucose AUC0\u20134 in the FMD group was non-inferior to that in the water fast group (p = 0.899). A breakfast group served as a control, which confirmed that the instrument used in home glucose and ketone monitoring functioned as expected. The results indicate that FMD bar consumption does not interfere with the physiological ketogenesis associated with overnight fasting and could be used to facilitate the practice of time-restricted eating or intermittent fasting.<\/jats:p>","DOI":"10.3390\/nu13051523","type":"journal-article","created":{"date-parts":[[2021,4,30]],"date-time":"2021-04-30T10:53:29Z","timestamp":1619780009000},"page":"1523","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["An Intermittent Fasting Mimicking Nutrition Bar Extends Physiologic Ketosis in Time Restricted Eating: A Randomized, Controlled, Parallel-Arm Study"],"prefix":"10.3390","volume":"13","author":[{"given":"Angie W.","family":"Huang","sequence":"first","affiliation":[{"name":"L-Nutra, Inc., Plano, TX 75024, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2649-9271","authenticated-orcid":false,"given":"Min","family":"Wei","sequence":"additional","affiliation":[{"name":"L-Nutra, Inc., Plano, TX 75024, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Caputo","sequence":"additional","affiliation":[{"name":"L-Nutra, Inc., Plano, TX 75024, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7785-4221","authenticated-orcid":false,"given":"Melissa L.","family":"Wilson","sequence":"additional","affiliation":[{"name":"Preventive Medicine, Keck School of Medicine, University of Southern California, Los Angeles, CA 90089, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Antoun","sequence":"additional","affiliation":[{"name":"L-Nutra, Inc., Plano, TX 75024, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William C.","family":"Hsu","sequence":"additional","affiliation":[{"name":"L-Nutra, Inc., Plano, TX 75024, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"59","DOI":"10.1126\/science.273.5271.59","article-title":"Oxidative stress, caloric restriction, and aging","volume":"273","author":"Sohal","year":"1996","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"201","DOI":"10.1126\/science.1173635","article-title":"Caloric restriction delays disease onset and mortality in rhesus monkeys","volume":"325","author":"Colman","year":"2009","journal-title":"Science"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"321","DOI":"10.1126\/science.1172539","article-title":"Extending healthy life span\u2014From yeast to humans","volume":"328","author":"Fontana","year":"2010","journal-title":"Science"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"361","DOI":"10.1093\/ajcn\/78.3.361","article-title":"Calorie restriction and aging: Review of the literature and implications for studies in humans","volume":"78","author":"Heilbronn","year":"2003","journal-title":"Am.
