Structured population data were available for 3 of 3 supporting studies. 3 studies described participants with type 2 diabetes. 2 studies described adult participants.

Evidence uses heterogeneous comparison contexts: active_comparator, usual_care.

1 study contains conflicting p-value and significance fields; those significance claims are suppressed.

No dietary restrictions

Core clinician-reference fields are available or not applicable.

Participants followed a 3-day per week intermittent fasting regimen with calorie intake restricted to a maximum of 500 kcal prior to noon.

Intermittent Fasting Group

The participants were randomly assigned to either 12 weeks of IF group ( n = 22) or a control group ( n = 24). The IF group followed a 3-day per week IF regimen, during which calorie intake was restricted to a maximum of 500 kcal prior to noon.

Participants in the control group had no dietary restrictions.

However, participants in the control group had no dietary restrictions.

Authoritative quality diagnostic: p value significance conflict.

Intermittent fasting aids weight loss in type 2 diabetes

Standard dietary counseling without caloric restriction

Participants practiced intermittent fasting 3 days a week, reducing their caloric intake on those days by 75%.

The IF group practiced IF 3 days a week, reducing their calories on these days by 75% (i.e., consuming only 25% of the recommended caloric intake).

Participants received dietary counseling without caloric restriction.

Both groups had a comparable number of interactions with the study staff.

Intermittent fasting improves glycemic control in insulin-treated type 2 diabetes

Participants fasted three non-consecutive days weekly, restricting intake to ~500 kcal.

Participants in the IF group fasted three non-consecutive days weekly (typically Monday, Wednesday, Friday), restricting intake to ~500 kcal (25% of daily needs) consumed at breakfast and/or lunch to maintain an 18-h fast.
