Is Intermittent Fasting Right for Everyone?

While intermittent fasting works well for many, experts caution that it’s not suitable for everyone. Some individuals may experience negative side effects, or fasting could trigger unhealthy patterns in those with a history of disordered eating. Consulting a registered dietitian is always advised before starting IF, especially if you have underlying health conditions.

“The best intermittent fasting plan enables sustainable weight loss while meeting your nutritional needs,” advises registered dietitian Bonnie Taub-Dix.
Always prioritize meeting daily calorie and micronutrient requirements.
If you feel overly hungry, fatigued, or stressed, IF may not be the best choice for you.
Children, pregnant women, or individuals with certain metabolic disorders should avoid intermittent fasting unless supervised by a professional.
