Study Arms (1)

Modified 5:2 IF diet

EXPERIMENTAL

The modified 5:2 IF diet involves 2 nonconsecutive fasting days (25%-30% of the total required daily energy intake based on ideal body weight) and 5 days of habitual intake (limited total energy intake according to ideal body weight) per week, as well as a 4-week run-in period and a minimum of 6,000 steps of physical activity per day.

Dietary Supplement: A modified 5:2 intermittent fasting diet

Interventions

The modified 5:2 IF diet involves 2 nonconsecutive fasting days (25%-30% of the total required daily energy intake based on ideal body weight) and 5 days of habitual intake (limited total energy intake according to ideal body weight) per week, as well as a 4-week run-in period and a minimum of 6,000 steps of physical activity per day.
