Metabolic and Inflammatory Outcomes of the Ketogenic Diet Comparing Saturated and Unsaturated Fat Sources

The goal of this clinical trial is to compare a healthy KETO diet supplemented with canola oil (KETO-Can) compared to a traditional KETO diet high in saturated fat (KETO-Sat) and low-fat diet (LFD) in adults at high risk of or diagnosed with type 2 diabetes. The main question\[s\] it aims to answer are: * Effects on CVD risk factors (plasma cholesterol, TG, ApoB100, glucose, insulin and HbA1C). * Effects on systemic inflammation and immune function. * Adherence to interventions. Participants will be randomized into 1 of the dietary treatments during which they will follow a Keto or a low-fat diet. Comparisons among groups at 3 and 6 months of intervention will be conducted.
