Researchers from the University of Bristol have challenged the long held belief that intermittent fasting automatically lowers appetite. The study, which appeared in the nutrition field of Nutrients, revisits the relationship between fasting patterns and sensations of hunger.
Intermittent fasting describes dietary patterns that alternate between periods of eating and fasting. Proponents say this approach helps with weight loss by dampening appetite, yet questions remain about how much appetite actually changes under such regimens. The Bristol team set out to determine if appetite declines as a direct result of these fasting schedules.
To answer this question, the researchers performed a meta analysis that pooled data from seventeen separate investigations. The analysis tracked changes in appetite alongside linked factors such as body weight, energy intake, meal patterns, and physical activity for all participants. The collective dataset included 1111 individuals who followed intermittent fasting or calorie restriction protocols in the included studies.
The findings indicated that intermittent fasting did not reduce appetite more than calorie restriction as previously assumed. In other words, appetite levels in those practicing fasting schedules were not measurably lower than those on standard calorie controlled diets, once the broader data were considered.
These results contribute to the ongoing discussion about how best to manage hunger and energy balance in weight management programs. They suggest that appetite responses to fasting are complex and may vary between individuals, rather than following a simple, predictable pattern. As such, practitioners and individuals should recognize that appetite outcomes may differ when selecting between fasting and non fasting approaches, and should tailor plans to personal experience and lifestyle realities. The Bristol researchers emphasize looking beyond hunger signals alone, considering how activity levels, meal composition, and total daily intake interact with dietary strategies to influence body weight over time.
Further research is encouraged to explore how different fasting windows, meal timing, and food quality influence appetite perceptions across diverse populations. This nuanced perspective helps clinicians provide balanced guidance and helps individuals make informed choices about whether intermittent fasting fits their health goals and daily routines, rather than assuming a universal appetite response.
