Verified step by step guidance

1. Understand that daily calorie intake needs vary based on individual factors such as age, sex, weight, height, activity level, and health status.
2. Recognize that reliable estimates come from evidence-based methods and personalized assessments rather than generalized or anecdotal sources.
3. Evaluate the credibility of sources: social media influencers and celebrity magazines often provide non-personalized, unverified information.
4. Identify that advertisements, especially those promising rapid results without lifestyle changes, are typically not scientifically valid.
5. Conclude that a registered dietitian nutritionist (RDN) uses validated nutrition assessment methods tailored to the individual, making them the most reliable resource for estimating daily calorie needs.
