Intermittent Fasting 101- Complete Guide

Intermittent Fasting: A Simple Guide to Smarter Eating

Intermittent Fasting isn't just a diet trend — Research suggests it's a lifestyle shift that's helped millions manage weight, boost energy, and simplify routines. Let's break down how it works, why it's effective, and how to do it safely.

What Is Intermittent Fasting?

Intermittent Fasting focuses on when you eat, not what you eat. It is an eating pattern alternating between fasting periods (when you don't eat) and eating windows (when you consume food).

It's not about starving yourself; it's about giving your body time to rest, repair, and burn fat effectively.

Historically, Fasting has been part of human evolution—early humans didn't always have access to food, and Fasting helped their bodies adapt. Even today, Fasting is a part of various cultures and religions, including Ramadan, Navratri, and Lent.

Why Intermittent Fasting Works: The Science Behind It

It’s backed by science. When you fast, your body shifts into fat-burning mode, lowering insulin levels and increasing human growth hormone (HGH), which helps break down stored fat for energy. It also triggers autophagy, where cells repair themselves by eliminating damaged components, promoting better metabolism and longevity. Studies suggest Intermittent Fasting can improve brain function, support heart health, and regulate blood sugar levels, making it more than just a weight-loss strategy—it’s a holistic approach to better health.
