Macro partitioning
Adherence to a ketogenic diet for 6-12 months produces transient improvements in weight loss, blood pressure, triglycerides, and HbA1c, but these benefits typically diminish and lose statistical significance after 12 months.
If you start a ketogenic diet, expect to see improvements in weight, blood pressure, and blood sugar within the first year. However, do not expect these benefits to persist indefinitely if you cannot maintain the diet strictly. After 12 months, the weight loss advantage over other diets disappears, and you may regain weight. To mitigate this, consider focusing on plant-based fats and proteins rather than animal-derived ones, as this may improve long-term sustainability and cardiovascular risk profiles.
Based on our review, within the first 6-12 months of initiating KD, transient decreases in blood pressure, triglycerides, and glycosylated hemoglobin, as well as increases in HDL and weight loss may be observed. However, the aforementioned effects are generally not seen after 12 months of therapy, as the changes reported in the studies we reviewed are not statistically significant.

The paper is a review of multiple meta-analyses and RCTs, but notes limitations in sample size and duration.
