The Effect of Personalized Nutrition on Changes in Metabolic Parameters in Patients With Type 2 Diabetes Mellitus

July 5, 2026 updated by: DINA KEUMALA SARI
Type 2 diabetes mellitus (T2DM) is a multifactorial metabolic disorder commonly accompanied by obesity, hypertension, and suboptimal glycemic control, which together increase cardiovascular risk. Conventional dietary recommendations often apply a uniform approach and may not adequately address interindividual metabolic variability. Personalized nutrition has therefore gained attention as a strategy to optimize metabolic outcomes through individualized dietary interventions. This controlled intervention study evaluated the effect of a personalized nutrition program "my plate" on metabolic parameters in patients with T2DM. Participants were assigned to either an intervention group receiving personalized dietary guidance or a control group receiving standard care. Anthropometric parameters (body weight, body mass index, and waist circumference), fasting plasma glucose, and blood pressure were assessed at baseline and after the intervention
