The Claim

Reducing the fat-to-carbohydrate ratio in the Classic Ketogenic Diet (e.g., to 2.5:1) may reduce adverse side effects but may compromise the diet's efficacy in controlling seizures.

Source: Short and long-term side effects of the Classic Ketogenic Diet in pediatric epilepsy treatment: A systematic review of clinical trials.

How it works

1 study reviewed

In plain English

A version of the keto diet that's less strict about fat (like a 2.5:1 ratio instead of the classic 4:1) might cause fewer side effects like constipation or high cholesterol, but it might also not work as well to prevent seizures.

Lower fat-to-carbohydrate ratios in the Classic Ketogenic Diet, such as 2.5:1, may reduce side effects but may potentially compromise the diet's efficacy in controlling seizures

What the research says

1 study

Study: Short and long-term side effects of the Classic Ketogenic Diet in pediatric epilepsy treatment: A systematic review of clinical trials.
The study looked at kids with epilepsy on the ketogenic diet and found that using a lower fat-to-carb ratio like 2.5:1 does indeed cause fewer side effects, but might not work as well to control seizures - exactly what the claim says.
