One of the most well-liked health trends worldwide is intermittent fasting. Intermittent fasting—especially the 16/8 method—offers a sustainable approach to improving overall health, regardless of your objective of weight loss, increased metabolism, or improved focus.
What is Intermittent Fasting 16/8?
Intermittent fasting (IF) is not a diet, but an eating pattern that cycles between periods of eating and fasting. The 16/8 method entails eating only during an eight-hour window and fasting for 16 hours per day. For example, you might eat between 12 PM and 8 PM, and fast from 8 PM to 12 PM the next day.
Why 16:8 Intermittent Fasting Works
This fasting method gives your body time to burn fat stores, regulate insulin levels, and repair cells. You naturally consume fewer calories when you limit the hours you eat, which aids in weight loss.
Benefits of Intermittent Fasting
The following are some scientifically proven advantages of intermittent fasting:
- Weight Loss & Fat Burn: Fasting boosts metabolism and triggers fat-burning hormones.
- Improved Brain Health: Enhances brain function and may reduce Alzheimer’s risk.
- Heart Health: Lowers blood sugar, cholesterol, and inflammation levels.
- Cellular Repair: Helps autophagy, the body’s natural process for cleaning cells, work better.
- Regulate Hormone: Regulates hormone levels by keeping insulin and growth hormone in check.
- Better Eating Habits: Limits mindless snacking and binge eating.

What You Should Know
Due to differences in hormones, women’s bodies react more strongly to fasting. Here are tips:
- Start with 14/10 instead of 16/8.
- Avoid fasting on days when you’re menstruating.
- Listen to your body: if fasting causes fatigue, adjust.
- Prioritize nutrient-dense meals with iron, protein, and healthy fats.
If you have PCOS, are pregnant, or have irregular menstrual cycles, always see a doctor.
Best Intermittent Fasting for Weight Loss
Intermittent fasting has been shown to be more long-lasting than traditional dieting for weight loss. The key is calorie balance and meal quality. Pair fasting with:
- A low-carb
- High-protein diet
- Plenty of fiber and vegetables
During a fast, hydrate with water, black coffee, or herbal tea. During your eating window, avoid processed foods and those high in sugar.
