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

1 supporting study does not have a displayable topic-matched quantitative effect.

Evidence uses heterogeneous comparison contexts: active_comparator, baseline_within_group, usual_care.

1 supporting study has high, serious, critical, unclear, or unavailable risk-of-bias information.

Standard-Protein Diet

Core clinician-reference fields are available or not applicable.

Participants received a high-protein diet consisting of 30% protein, 40% carbohydrates, and 30% fat.

High-Protein Diet

In this randomized controlled study, 76 overweight and obese patients aged 57.7 years, 72.4% male, were randomized to a high-protein (30% protein, 40% carbohydrates, and 30% fat) or standard-protein diet for 3 months.

Participants received a standard-protein diet consisting of 15% protein, 55% carbohydrates, and 30% fat.

In this randomized controlled study, 76 overweight and obese patients aged 57.7 years, 72.4% male, were randomized to a high-protein or standard-protein diet for 3 months.

High-protein diet may reduce cardiometabolic risks in diabetes patients

Available source content was suppressed because validation identified a conflict.

Low-Protein Diet (LP)

Participants followed a high-protein diet for 12 weeks.

High-Protein Diet (HP)

We therefore performed a multi-center, randomized-controlled, isocaloric protein intervention with 151 participants following either 12-week high-protein (HP; 30Energy %, N= 78) vs. low-protein (LP; 10 Energy%, N= 73) diet.

Participants followed a low-protein diet for 12 weeks.

High-protein diet shows little effect on glycemic control in diabetes

Clinician-reference record is usable with limitations in: comparator.

Participants received a high-protein diet consisting of 70% protein from omnivorous sources.

Omnivorous Diet (OMNI)

Participants were allocated using simple randomization to a high-protein diet; either an omnivorous diet (OMNI; 70% protein from omnivorous sources)

Participants received a high-protein diet consisting of 50% protein from mycoprotein.

Vegan Diet (VEG)

Participants were allocated using simple randomization to a high-protein diet; either an isonitrogenous mycoprotein-rich vegan diet (VEG; 50% protein from mycoprotein)
