Adherence

Intermittent Caloric Restriction (ICR), specifically Alternate Day Fasting (ADF), is as effective as Continuous Caloric Restriction (CCR) for weight loss but offers superior compliance and lean mass retention.

Try Alternate Day Fasting: Eat normally on one day, then restrict calories significantly (or fast) the next. This method is just as effective for weight loss as daily calorie counting but may be easier to stick to because you aren't restricted every day.

Intermittent CR, including alternate day fasting (ADF), was as effective as continuous CR but may show improved compliance and higher lean mass.
