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

Condition(s) studied

Investigational drug(s) / intervention(s)

Keto-SAT: Nutrition counselling focused on Keto diet (saturated fat). 10% TE as carbohydrate (mainly from vegetables and whole grain products), protein between 20-30% TE and fat between 60-70%.

Keto-CAN: Nutrition counselling focused on Keto diet (unsaturated fat). 10% TE as carbohydrate (mainly from vegetables and whole grain products), protein between 20-30% TE and fat between 60-70%.

LFD: Nutrition counselling focused on low-fat diet. 30% total energy (TE) as fat, 50% TE as carbohydrates (primarily whole grains) and 17-20% TE protein (mainly lean sources).

Study summary

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.

Eligibility

Primary outcome measure(s)

• Effect of diets on plasma triglycerides levels by comparing groups at 3 months of intervention (i.e. control low fat diet and the 2 keto groups) and changes over time within each group (i.e. baseline vs. 3 months). — 3 months
  Assess triglycerides levels collecting blood samples in a fasting state. Triglycerides will be determined using commercially available equipment at a local laboratory (Roche Cobas c503). Measurements will be performed for between group comparison and within groups comparison to understand the effect of diets.
• Effect of diets on plasma triglycerides levels by comparing groups at 6 months of intervention (i.e. control low fat diet and the 2 keto groups) and changes over time within each group (i.e. baseline vs. 6 months). — 6 months
  Assess triglycerides levels collecting blood samples in a fasting state. Triglycerides will be determined using commercially available equipment at a local laboratory (Roche Cobas c503). Measurements will be performed for between group comparison and within groups comparison to understand the effect of diets.
• Effect of diets on LDL-cholesterol levels by comparing groups at 3 months of intervention (i.e. control low fat diet and the 2 keto groups) and changes over time within each group (i.e. baseline vs. 3 months). — 3 months
  Assess LDL-cholesterol levels collecting blood samples in a fasting state. LDL-Cholesterol levels will be determined using commercially available equipment at a local laboratory (Roche Cobas c503). Measurements will be performed for between group comparison and within groups comparison to understand the effect of diets.
• Effect of diets on LDL-cholesterol levels by comparing groups at 6 months of intervention (i.e. control low fat diet and the 2 keto groups) and changes over time within each group (i.e. baseline vs. 6 months). — 6 months
  Assess LDL-cholesterol levels collecting blood samples in a fasting state. LDL-Cholesterol levels will be determined using commercially available equipment at a local laboratory (Roche Cobas c503). Measurements will be performed for between group comparison and within groups comparison to understand the effect of diets.
