Losing weight and achieving your ideal body isn’t easy—it takes serious commitment, consistency, and a whole lot of patience. While there’s no magic fix, that hasn’t stopped people from trying every trick in the book. From trendy diet plans to supplements and shakes, the pursuit of weight loss often pushes people to extremes, sometimes even putting their health at risk.

One approach that’s gained serious traction lately—thanks to athletes, wellness influencers, and celebrities—is intermittent fasting. But this isn’t some modern-day gimmick. In fact, the practice of fasting dates back centuries, used by various cultures and religions long before it became the latest buzzword in the fitness world.

So, what is intermittent fasting exactly? Unlike traditional diets that tell you what to eat, intermittent fasting focuses on when you eat. By scheduling periods of eating and fasting, the body is given time to reset, which can lead to a range of health benefits. And yes, weight loss is one of them.

If done properly, intermittent fasting can help balance blood sugar, improve the body’s response to insulin, and trigger fat-burning mechanisms. But as with any restrictive eating plan, it’s not a one-size-fits-all solution.

A recent viral video from a popular YouTube channel took a closer look at the effects of a 36-hour fast, breaking it down minute by minute. The results were fascinating—and a little unexpected.

In the first few hours after your last meal—around the four-hour mark—your body starts tapping into fat stores for energy. That’s when fat burning begins, which is encouraging if you’re trying to shed pounds.

After about eight hours, blood sugar levels drop, and the body turns to stored glycogen for fuel. At this stage, your body is running on what it has saved from your previous meals. By hour twelve, things get even more interesting. The glycogen runs out, and your body switches gears, breaking down stored fat in the liver to produce fatty acids called ketones. This switch to ketones for fuel is called metabolic switching, and it’s the secret sauce behind many weight loss success stories.

At sixteen hours, something powerful kicks in: autophagy. This is the body’s way of spring-cleaning itself. Old and damaged cell parts are recycled and repurposed, which can promote longevity and reduce the risk of diseases. It’s one of the reasons intermittent fasting has been linked to anti-aging effects.

Now, fast forward to the 24-hour mark. This is when your body goes into full fat-burning mode. Inflammation decreases, insulin sensitivity improves, and your metabolism gets a boost. The body is operating at a higher level of efficiency, focusing on repair and energy conservation.

By the time you hit 30 hours, the real “deep cleaning” begins. And at 36 hours? That’s when the body reaches peak autophagy. Cells are regenerating, tissues are repairing, and your system is essentially getting a full internal tune-up.

Sounds amazing, right? But before you rush into a 36-hour fast, it’s important to be aware of the downsides too. Like any diet or health routine, intermittent fasting can come with side effects—especially if it’s not done with care.

According to experts at The Emily Program, some people may experience side effects such as extreme hunger, dizziness, headaches, mood swings, stomach problems, bad breath, trouble sleeping, dehydration, frequent urination, and in more serious cases, nutritional deficiencies and even malnutrition.

That’s why intermittent fasting isn’t ideal for everyone. People with certain medical conditions, pregnant or breastfeeding women, or those with a history of disordered eating should consult a healthcare provider before starting a fasting routine.

Still, for those who are healthy and able to follow a fasting plan safely, the benefits can be impressive. From improved metabolism and lower inflammation to increased cellular repair and steady fat loss, intermittent fasting offers more than just a slimmer waistline—it supports overall well-being.

But remember, consistency and balance are key. Fasting is not a license to overeat during your eating windows, and it’s definitely not a shortcut to perfect health. The best results come when intermittent fasting is combined with nutritious food choices, regular physical activity, and good sleep hygiene.

So, if you’re thinking about giving intermittent fasting a try, start slow. Begin with shorter fasts, like 12 or 16 hours, and work your way up if it feels right for your body. Stay hydrated, listen to your body’s signals, and most importantly, don’t push yourself to extremes.

Whether you’re looking to drop a few pounds, reset your system, or just try something new, intermittent fasting may be worth exploring. Just make sure you do it the smart and healthy way.
