What Is Intermittent Fasting?

In plain English, intermittent fasting (IF) is simply a pattern of eating that cycles between periods of eating and periods of not eating. Its not a diet about what you eat, but when you eat.

How it works in the body

When you fast, insulin levels drop, making it easier for your body to burn stored fat. After about 1216hours without food, your body also kicks into a repair mode called autophagy, where it clears out damaged cells. The science behind these processes is backed by research from institutions such as and .

Quick visual: 16/8 timeline

Imagine a clock: you finish dinner at 8pm, then skip breakfast and have your first meal at 12pm the next day. That 16hour fast followed by an 8hour eating window is the classic 16/8 method.

Picking the Right Schedule

There isnt a onesizefitsall IF schedule. The best one for you depends on your lifestyle, goals, and how your body reacts.

During the fast, water is your best friend. Black coffee, unsweetened tea, and sparkling water are also finejust keep calories at zero. Adding a pinch of sea salt or a splash of electrolyte powder can help if you feel lightheaded.

• 12:00pm First meal (protein + veg + healthy fat).

Eating During Fasting

What you eat in the 8hour window matters just as much as the fasting itself. Focus on foods that keep you full, steady your blood sugar, and supply the nutrients your body needs to thrive.

Best foods to keep you satisfied

• Fiberrich veggies: broccoli, spinach, peppers, zucchini.
• Healthy fats: avocado, olive oil, nuts, seeds.
• Complex carbs (in moderation): quinoa, sweet potatoes, oats.

Skip anything that spikes insulin dramatically or leaves you hungrier later: sugary pastries, white bread, candy, soda, and large portions of refined carbs. These can also undermine the fatburning benefits of fasting.

What to eat during intermittent fasting sample meals

• First meal (12pm): Scrambled eggs with spinach, a side of avocado, and a handful of berries.
• Snack (4pm): A small handful of almonds and a cup of unsweetened herbal tea.
• Last meal (7pm): Grilled salmon, quinoa pilaf, roasted broccoli, and a drizzle of olive oil.
