Intermittent fasting only works if it is a tactic to reduce calories. The act of normalizing hunger does not in and of itself reduce body fat.
Researchers from the University of Illinois Chicago found that participants in the time-restricted eating group ate 425 fewer calories than the control group and lost roughly 10 more pounds than the control group after one year.
However, participants in the calorie-restricted group ate 405 fewer calories per day and lost about 12 more pounds after one year. Participants in both groups demonstrated strong adherence to their respective interventions.
