Everything You Need To Know About Intermittent Fasting And Weight Loss

Who doesn’t want to lose a bunch of kilos without quitting their favorite snacks or following a strict routine? Take it from me – back when I weighed 10kgs more than my recommended weight, I’d get frustrated eating just boiled chicken and veggies to lose weight. I didn’t feel full, or satisfied. And guess what? I’d end up binge-eating candies and chocolates late at night!

This is when I discovered intermittent fasting – a rather flexible diet that can easily be incorporated into your lifestyle. This diet completely revamps your approach to diets and weight loss, creating a healthy balance between the two.

With intermittent fasting, your focus isn’t on what you’re eating—it’s on when you’re eating, which gives you amazing health benefits and a snatched waist. So, if you’re struggling to get those packs, with this guide, you won’t have to worry about a bulging belly anymore!

A little more challenging and demanding than the 16/8 one, the eat-stop-eat is a 24-hour fast. You’re supposed to do this anywhere between 1 and 3 times a week. Although this is a lot more difficult, it boosts your weight loss and offers several health benefits. However, you must practice this responsibly to avoid any drawbacks.


  • Weight Loss Boost: Fasting for 24 hours 1-3 times a week can create a calorie deficit, which boosts weight loss.
  • It’s Simple: Although this is not easy to follow, it is simple. You don’t have to develop a plan or count calories, and you also don’t need to prep smaller portions.
  • Cellular Repair Process Enhanced: The longer fasting period will improve your cellular repair process and decrease any signs of inflammation.

5:2 Diet

In this intermittent fasting schedule, nothing out of the norm is happening. You’re supposed to consume your meals normally for 5 days a week. However, for any 2 days within the week, you should cut your calorie consumption to 500 or 600 kcal. This decrease in your calorie intake charges up your weight loss process.


  • Caloric Management: You’re only cutting back your calories two days a week, which isn’t too stressful and is doable practically.
  • Improved Metabolism: This intermittent fasting schedule helps regulate your blood sugar levels, increasing your insulin sensitivity on days when your caloric intake is less.
  • Good For Long-Term Practice: This diet isn’t as limiting as others, so it’s much more sustainable and easier to incorporate into your lifestyle.

How Does Intermittent Fasting Work?


Intermittent fasting leads to weight loss by boosting your body’s fat-burning process. It also amps up your metabolic rate, which improves your overall digestion. While fasting, the insulin levels in your body decrease and the human growth hormone levels rise. This leads to fat burn and muscle gain.

Moreover, this process improves your metabolism, leading to consistent weight loss. This is a long-term strategy, which makes this a sustainable lifestyle.

How Does Intermittent Fasting Affect Your Hormones?

Here’s how intermittent fasting impacts the hormones and cellular procedures in your system:

  • Lower Insulin Levels: With reduced insulin levels, fasting boosts the fat-burning process.
  • Human Growth Hormone (HGH): As this hormone’s production increases, it leads to effective muscle gain and fat loss.
  • Cellular Repair: As cells go into repair and regeneration mode, there’s no more buildup of old protein. This means your overall body function improves.
  • Gene Expression Improvement: Your lifespan will likely extend as many of your genes and molecules transform. In addition, this also protects you from diseases.

What is the best intermittent fasting for weight loss?

The best method for intermittent fasting for weight loss is the 16/8 schedule. This schedule allows you to have an 8-hour eating window while fasting for 16 hours.

Several studies reveal that this method of intermittent fasting helps you lose weight and get a slimmer waist, especially when you exercise as well.
