Intermittent Fasting

Intermittent fasting (IF) is an umbrella term for various eating patterns that cycle between periods of eating and fasting. Common methods include the 16/8 method (16 hours fasting, 8 hours eating), 5:2 method (normal eating 5 days, very low calorie 2 days), and alternate-day fasting. IF does not prescribe specific foods but rather focuses on timing meals to improve metabolic health, promote fat loss, and simplify eating routines. Many people find it easier to reduce calorie intake by limiting the eating window. Research suggests IF may improve insulin sensitivity, reduce inflammation, and support weight loss. However, it may not be suitable for everyone, especially those with certain medical conditions or who are pregnant.

By restricting the time window for eating, intermittent fasting naturally reduces calorie intake and improves metabolic flexibility. Fasting periods allow insulin levels to drop, promoting fat burning and cellular repair processes like autophagy. The body shifts between using glucose and fat for energy, which can improve metabolic health markers. The simplicity of not having to plan multiple meals can also improve adherence for some individuals.
