Study: Hype around Intermittent Fasting Not Warranted - Intermittent fasting fails to outperform traditional diets in weight loss study

A new review suggests intermittent fasting may not be better for weight loss than traditional diets. The findings come as global obesity rates continue to rise, with 2.5 billion people overweight in 2022 alone. Researchers found little difference in results between fasting and other methods.

The study analysed 22 trials comparing intermittent fasting to standard diets. Three common fasting variants—8:16, 5:2, and alternate-day fasting—were mentioned, but the exact methods varied widely. This inconsistency made it difficult to draw firm conclusions.

Results showed no clear advantage in weight loss or quality of life for those using intermittent fasting. The review also highlighted a lack of long-term data, leaving questions about sustainability. Experts emphasised that the most effective diet is one people can maintain over time.

Weight loss remains critical for reducing health risks linked to obesity. While intermittent fasting is popular, the evidence does not prove it superior to other approaches. Those seeking to lose weight are advised to choose a method that fits their lifestyle, preferably with professional guidance.
