Intermittent fasting: does it work for weight loss?
16:8, 5:2 and other fasting methods explained, what the research says, and who should avoid it.
Intermittent fasting has become one of the most popular diet approaches. Instead of focusing on what you eat, it focuses on when. But does it work better than other diets?
Common methods
- 16:8: eat within an 8-hour window each day, such as noon to 8pm
- 5:2: eat normally five days a week and significantly reduce calories on two non-consecutive days
- Time-restricted eating: any approach that limits eating to a set window
What the research says
Studies suggest intermittent fasting can help with weight loss, mainly because a shorter eating window tends to reduce total calories. When calories are matched, many studies find results similar to regular calorie reduction. In other words, it works if it helps you eat less, not because of fasting itself.
Who it might suit
- People who aren't hungry in the morning
- People who find a clear rule easier than counting
- People whose evening snacking is the main problem
Who should avoid it
- Anyone with a history of eating disorders
- Pregnant or breastfeeding women
- People with diabetes, especially on medication, without medical advice
- Young people who are still growing
Make your eating window count
If you try fasting, plan nutrient-dense meals with plenty of protein and vegetables so you stay full through the fast. Mealful lets you plan just the meals you eat, so a two-meal day still hits your calorie and protein goals.
