Intermittent fasting, in short
Intermittent fasting is an eating pattern that focuses on when you eat rather than what you eat, cycling between eating and fasting windows. Common approaches include the 16:8 method and the 5:2 pattern, and it is popular for being flexible and easy to fit around life.
This guide covers what intermittent fasting is, the common methods like 16:8 and 5:2, why people choose it, and how to get started safely and well.
Intermittent fasting has become one of the most popular approaches to wellness, largely because it is simple and flexible.
Here are the questions people ask most. For more, see our natural health and herbal tips guide.

What is intermittent fasting?
It is an eating pattern that focuses on when you eat, cycling between periods of eating and not eating.
Rather than changing what is on your plate, it changes the timing of your meals.
That simplicity is a big part of why so many people get on with it.
What are the common methods?
The best-known approaches are the 16:8 method and the 5:2 pattern.
The main methods:
- 16:8 — fast for 16 hours, eat within an 8-hour window.
- 5:2 — eat normally for five days, lighter meals on two non-consecutive days.
- Alternate-day — alternate normal-eating days with lighter days.
Why do people choose intermittent fasting?
Many find it a simple way to add structure to their eating and be more mindful of snacking.
Some enjoy the routine of set eating windows; others find it helps them pay closer attention to their meals.
It is also an active area of research, so interest keeps growing.
How do you get started safely?
Start gradually, stay hydrated, and choose nutrient-dense foods during your eating windows.
Sensible pointers:
- Ease in — begin with a manageable window and extend slowly.
- Hydrate — drink plenty of water during fasting periods.
- Eat well — whole, varied foods when you do eat.
- Listen to your body — adjust to how you feel.
Is intermittent fasting right for everyone?
No – it suits some people well and others not at all, so it is worth approaching thoughtfully.
If you are pregnant, have a health condition, or a history of disordered eating, speak to your GP first.
The aim is to support your wellbeing, not to impose rigid rules.
