Alternate-day fasting (ADF) has gained popularity in recent years. The diet consists of a “fast day” where an individual consumes 0–25% of their energy needs, alternated with a “feast day” where a person is permitted to eat ad libitum.
Aim:
This study examined eating behavior traits of successful weight losers during alternate day fasting.
Methods:
Obese participants (n = 34) took part in 12 months of ADF and were grouped into a high (≥5%) or low-weight-loss (<5%) group post-treatment.
Results:
The high-weight-loss group demonstrated increased (p = 0.04) fullness, decreased (p = 0.03) hunger, increased dietary protein intake (15% to 20% of kcal, p = 0.04), and better adherence to fast-day calorie goals.
Conclusions:
Thus, individuals who achieve clinically significant weight loss with ADF demonstrate improved satiety, increased protein intake, and better adherence to fast-day calorie goals.
