Registered Dietitians Discuss the Intermittent Fasting Phenomenon

Intermittent fasting has become the latest trend in dieting, attracting attention for its unique approach. The concept is simple: designate specific time frames for fasting and eating. Many individuals choose to fast for 14-16 hours each day, commonly skipping breakfast and refraining from eating after 7 p.m., or they might opt for two full fasting days each week while eating normally on the others.

But let’s pause for a moment. Doesn’t this resemble a more sophisticated form of disordered eating?

Before anyone claims that intermittent fasting is merely a lifestyle choice rather than a diet, let’s clarify: any structured eating pattern is, by definition, a diet. While diets can be beneficial for some—like those managing diabetes or food allergies—they often come with their own challenges.

One of the main attractions of intermittent fasting is the flexibility it offers during eating windows; followers can indulge in a variety of foods without needing to count calories or restrict certain items. However, limiting eating to specific hours often leads to ignoring natural hunger cues, which can foster disordered eating behaviors. Even if some find short-term success with intermittent fasting, its sustainability is questionable.

Research indicates weight loss is common among participants, but adherence can be a significant issue. A study from Harvard School of Public Health noted that 29-38% of people dropped out within the first six months. Systematic reviews showed dropout rates could soar to 65% in some instances.

While proponents of intermittent fasting claim various health benefits—like improved energy levels, mood enhancement, and reduced diabetes risk—the mental health implications are often overlooked. Individuals with a history of eating disorders, in particular, should approach such restrictive eating patterns with caution.

I can personally relate to this topic through my own experience from two decades ago. Back in college, I developed an unhealthy relationship with food, using binging as a coping mechanism for anxiety and trauma. When I discovered I could fast all day, only consuming coffee, I lost a significant amount of weight. However, this led to physical issues like dizziness and migraines, and I struggled with food for years afterward. It wasn’t until I embraced my body and stopped dieting that I truly found peace with food.

Hearing about intermittent fasting reminds me of my past and the struggles many face with food and dieting. With so many people caught in a cycle of fad diets, it’s hard not to fear the potential risks associated with intermittent fasting. It’s likely that many will try it, only to drop out and regain any lost weight, perpetuating a cycle of disappointment and disordered eating.

Summary

Intermittent fasting is a trending dietary approach that involves designated periods of fasting and eating. While it offers flexibility and has been linked to some health benefits, it also raises concerns about sustainability and potential mental health risks, particularly for those with a history of eating disorders. Embracing body acceptance and moving away from restrictive diets may lead to a healthier relationship with food.
