Intermittent fasting involves cycling between periods of eating and fasting, with various methods focusing on when and how long to eat or abstain from food.
Common intermittent fasting methods include the 16/8 method (16 hours of fasting and an 8-hour eating window) and the 5:2 method (eating regularly for five days and restricting calorie intake on two non-consecutive days).
Intermittent fasting often results in calorie restriction, which can contribute to weight loss. However, the focus is more on when to eat rather than what to eat.
Intermittent fasting may lead to metabolic changes, including improved insulin sensitivity and increased levels of norepinephrine, potentially enhancing fat burning.
Fasting periods stimulate autophagy, a process where cells remove damaged components. This may contribute to cellular repair and longevity.
Intermittent fasting affects hormones such as insulin and human growth hormone, which play roles in metabolism and fat storage.
For some, intermittent fasting is a sustainable lifestyle choice, providing flexibility in when meals are consumed and potentially simplifying meal planning.
Intermittent fasting may promote more mindful eating by reducing the frequency of meals and snacks, leading to better awareness of hunger and satiety cues.
