Which stepwise approach best synthesizes how a clinician should evaluate a new diet promoted to patients?

Recommend immediately if the diet is popular on social media; popularity equals safety and efficacy, so no further review is needed

Advise the patient to purchase the proprietary products to ensure they follow the diet correctly before evaluating evidence

Check for peer-reviewed evidence and duration of trials; review macronutrient and micronutrient adequacy against DRIs; identify elimination of food groups, product sales, or unrealistic promises; counsel based on safety and sustainability

If testimonials are compelling, accept the diet since individual stories are the strongest form of clinical evidence
