Another was the participants’ self-reporting. The study caveats included the method of recruiting which could pose a selection bias. Varying patterns of association between IF and ED behaviours were found across genders, including the TGNC cohort, but are more pronounced in women. Overall, 47.7 percent of women, 38.4 percent of men, and 52 percent of transgender or gender non-conforming (TGNC) individuals reported adhering to IF in the past 12 months. Multiple modified Poisson regression analyses were used to determine the link between IF (past 12 months and 30 days) and ED behaviours and psychopathology. They answered questions about weight perception, weight change behaviours, their IF engagement, and ED behaviours. Participants were recruited from social media ads in November and December 2021. Ganson and team analysed data from the Canadian Study of Adolescent Health Behaviours, a national study of Canadian adolescents and young adults (n=2,762). He said evidence on the effectiveness of IF for weight loss and disease prevention has been mixed, but it is important to understand the potential harms of IF. “The study shines a light on the fact that engagement in IF may be connected with ED behaviours, requiring healthcare professionals to be aware of this contemporary and popular dietary trend, despite proponents on social media touting its effectiveness and benefits,” said study investigator Dr Kyle Ganson from the University of Toronto in Toronto, Ontario, Canada. Similarly, IF in the past 12 months in men was associated with compulsive exercise and higher EDE-Q. IF in the 12 months and 30 days in women were significantly associated with overeating, binge eating, vomiting, laxative use, and compulsive exercise, as well as higher scores on EDE-Q, a measure of ED psychopathology. However, a new study linked IF to problematic eating disorder (ED) behaviours. Inducing a ketogenic state has also been linked to decreases in cardiovascular risk factors. Eating within a 6-hour window period and fasting for 18 hours can trigger a metabolic switch from glucose-based to ketone-based energy, which can increase stress resistance, improve longevity, and keep cancer and other diseases at bay.
Proponents of IF said our bodies have evolved to function well for extended hours, or days, without food. Currently in vogue, intermittent fasting (IF) – which switches between periods of eating and fasting – may not be as beneficial as many have thought.Ĭontrolling when you eat – not what you eat – has been shown to aid weight loss and improve metabolic health, blood pressure, cholesterol, and blood glucose in a plethora of studies.
