- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- The participants in the Healthy Low Carbohydrate Diet (HLCD) alone group were provided with HLCD and instructed to follow their usual eating regimens during the 12 week feeding trial. The HLCD was a relatively healthy type of LCD consisting of approximately 30%, 50%, and 20% of total energy from carbohydrates, fats, and proteins, emphasizing the consumption of unsaturated fatty acids, plant proteins, and high-quality carbohydrates including whole grains, fresh vegetables, and fruits.
