About this trial

The goal of this proposal is to determine the effect of a high protein diet in which the increase in protein intake is derived from different sources (animal vs plant and protein-rich whole foods vs protein isolates) on: i) liver and muscle insulin sensitivity; ii) the metabolic response to a meal, and iii) 24-h plasma concentration profiles of glucose, glucoregulatory hormones, and protein-derived metabolites purported to cause metabolic dysfunction.

Eligibility criteria

Qualifiers

age: ≥21 and ≤70 years;

BMI: >24.5 and <32.5 kg/m2;

habitual protein intake <0.9 g/kg/day (assessed on 2 weekdays and 2 weekend days by using the HealthWatch 360 app); and

weight stable (i.e., ≤3% change) and untrained (≤150 min of structured exercise/week) for at least 2 months before entering the study.

Disqualifiers

prediabetes or type 2 diabetes;

evidence of chronic kidney disease by medical history or laboratory tests (glomerular filtration rate <60 ml/min/1.73 m2 or an albumin to creatinine ratio in urine ≥30 mg/g);

vegetarians or vegans;

intolerance or allergies to ingredients in the metabolic meal or intervention diet;
