Randomized Controlled Trial
Acute intake of fructooligosaccharide and partially hydrolyzed guar gum on gastrointestinal transit: A randomized crossover clinical trial.
Dietary fibers, such as fructooligosaccharide (FOS) and partially hydrolyzed guar gum (PHGG) have several gastrointestinal functions. The aims of this study were to evaluate the effect of acute ingestion of FOS and PHGG on the percentage of gastric emptying and small intestinal transit and to evaluate the effect of these dietary fibers on the levels of intestinal hormones-active glucagon-like peptide-1, pancreatic polypeptide, and gastric inhibitory peptide-and their effect on feelings of hunger and satiety and the desire to eat. ⋯ The acute intake of FOS increased gastric emptying, whereas both FOS and PHGG reduced small intestine transit without altering the levels of intestinal hormones, hunger feelings and satiety, or the desire to eat.

Randomized Controlled Trial
Dietary recommendations for fasting days in an alternate-day intermittent fasting pattern: A randomized controlled trial.
The aims of this study were to explore the safety and effectiveness of alternate-day fasting in Chinese people and to compare weight loss outcomes and safety when consuming a high-protein (HP) versus a normal protein (NP) diet versus a nutritional meal replacement (MR) on fasting days. ⋯ ADF is an effective, short-term weight loss strategy that was tolerated by most Chinese participants. We suggest that dietary patterns during fasting days is less important, and that calorie restriction during those days should be the focus.
