A well-formulated ketogenic diet (carbohydrate restriction ≤50 g/d with >70% fat) is more effective than low-fat diets for treating obesity and type 2 diabetes, offering superior weight loss, glycemic control, and hunger suppression.

Adopt a ketogenic diet by restricting carbohydrates to 50 grams per day and ensuring fats make up more than 70% of your calories. Focus on high-quality fats (avocado, nuts, olive oil) and non-starchy vegetables. This approach has been shown to significantly reduce weight and blood sugar in people with type 2 diabetes, often allowing for reduced medication use. It is considered a first-line treatment option by the author based on current evidence.

Based on available evidence, a well-formulated ketogenic diet does not appear to have major safety concerns for the general public and can be considered a first-line approach for obesity and diabetes.
