From intermittent fasting apps to celebrity endorsements, it’s hard to avoid the conversation.
But is fasting genuinely beneficial, or is it simply another passing fad in the wellness world?
Let’s take a closer look at both sides of the debate.
The Case For Fasting
Many people who practise fasting describe it as a life-changing approach to health. There’s more than one way to do it, from intermittent fasting (16:8), where you eat during an eight-hour window and fast for sixteen, to alternate-day fasting, or even more extended fasts under medical supervision.
1. Improved Metabolic Health
Supporters argue that fasting helps regulate blood sugar, improve insulin sensitivity, and encourage fat loss without necessarily reducing calorie intake. Some studies suggest it may help reduce inflammation and oxidative stress, both key factors in long-term health.
2. Simplicity and Mindful Eating
Unlike complicated diets requiring strict meal plans or expensive supplements, fasting can simplify life. You eat less often, which may encourage more mindful food choices and less impulsive snacking.
3. Potential Longevity Benefits
Animal research and limited human trials suggest fasting could activate processes like autophagy, where the body clears out damaged cells. This has been linked to slowing aspects of ageing and reducing the risk of chronic diseases.
The Case Against Fasting
Of course, fasting isn’t for everyone, and critics warn that it can carry risks and reinforce unhealthy attitudes toward food.
1. Not Suitable for All Lifestyles
Those with physically demanding jobs, chronic conditions, or certain medications may find fasting difficult or even unsafe. It can cause fatigue, dizziness, and poor concentration, especially when combined with caffeine or strenuous activity.
2. Risk of Disordered Eating
Some nutritionists caution that fasting can blur the line between structured eating and restrictive behaviour, potentially triggering disordered eating patterns. This is particularly concerning among young people or anyone with a history of body image issues.
3. Limited Long-Term Data
While short-term studies on intermittent fasting look promising, long-term research is still limited. We don’t yet know whether the metabolic benefits seen early on persist after years of following a fasting routine.
Finding a Balanced Approach
For many people, fasting works best when it’s flexible and personal. You might find that delaying breakfast, avoiding late-night snacking, or having an occasional light day can deliver the benefits without full-on restriction.
Health professionals generally agree that fasting should never replace a balanced, nutrient-rich diet — nor should it become an excuse to overeat during eating windows.
The Verdict
So, is fasting a valid lifestyle choice or a fad? The answer depends on how it’s approached.
Used thoughtfully and under proper guidance, fasting can be a sustainable way to manage weight, improve metabolic health, and reconnect with hunger cues. However, when used as a quick-fix or pushed to extremes, it risks becoming yet another wellness trend that fades as quickly as it arrived.
If you’re considering fasting, it’s wise to consult a GP or registered dietitian first — especially if you have underlying health conditions.
In summary: fasting can be both valuable and valid, but only when applied responsibly. Like many things in life, balance is key.
