Is Intermittent Fasting Scientifically Approved?

So, you’re thinking about trying intermittent fasting (IF) because, well, your favourite Instagram influencer swears by it? How about pausing for a moment? Before jumping on the latest and trading diet plan, have you ever wondered if intermittent fasting is even for you? Raise your eyebrows as far as you want. But the truth won’t change. And the truth is, it or not, many scientific studies suggest that a simple calorie-restricted diet can have similar benefits to IF. Yet here we are, endlessly debating what the best approach is for a “healthy diet.”

Now, let’s clarify one thing: intermittent fasting didn’t magically appear out of thin air. It’s been around for a while, popularised by Dr Michael Mosley’s 2012 BBC documentary Eat Fast, Live Longer, and then further by Kate Harrison’s book The Fast Diet. While a substantial portion of the scientific community believes in its potential benefits, IF can be fatal for some people. Shocking, right? So, let’s plunge into what intermittent fasting is all about—its benefits, downsides, and whether it’s really worth all the hype.

5 Amazing Benefits of Intermittent Fasting

1. Weight Loss

Let’s face it, most of us consider intermittent fasting to lose those extra pounds. And hey, it has its moments. Different studies show different results. Let’s do a quick analysis of the past findings of these studies. Shall we?

But let’s take an oath of not getting too carried away. A 2022 study shows that to follow intermittent fasting, individuals followed a 5:2 intermittent diet plan. This 5:2 intermittent diet Plan helped participants lose 9.0 ± 5.3% of their baseline body weight. Yes, that’s quite a range!

Here’s a quick breakdown of the Different Scientific findings of people who choose IF:

 2022 :

131 individuals with obesity  9% weight loss over 12 weeks using the 5:2 method

 2020:

27 studies showed weight loss ranging from 0.8%–13% of baseline body weight following intermittent fasting

2020:

16:8 Method Diet Plan followers  felt Significant weight loss when eating was restricted to an 8-hour window

Sure, these results seem promising. But let’s be clear, most studies also point out that regular calorie-restricted diets show similar results. So, there you go—weight loss? Yes, but no magic bullet here.

2. Lower Risk of Type-2 Diabetes

Some say intermittent fasting could reduce insulin resistance, potentially lowering the risk of type 2 diabetes. A 2022 Review concluded that IF might indeed lower insulin production due to reduced calorie intake. However, this same review also noted the lack of solid evidence that intermittent fasting is any more effective than traditional caloric restriction. More research is obviously needed.

Just to add some spice to this debate, a 2018 rat study suggested that intermittent fasting could increase the risk of diabetes. Surprising, isn’t it? The study tracked intermittent fasting in rats over three months. Of course, more research is needed to see if these findings apply to humans. Then, a 2015 Study noted that intermittent fasting could regulate blood sugar better in males than in females. It heightens blood sugar levels in women only after three weeks of fasting.

So, IF might not be the holy grail for Type-2 diabetes prevention, especially for everyone.

3. Improved Heart Health

IF has been linked to better heart health. A 2016 Review suggested that intermittent fasting could lower blood pressure, heart rate, cholesterol, and triglycerides in humans and animals. Now, don’t get too excited; triglycerides are fats linked to heart disease. Lowering them is definitely beneficial, but how much of it can be solely attributed to intermittent fasting is still up for debate.

4. Changes in the Function of Hormones

Intermittent fasting can trigger some pretty interesting changes in your body. Let’s look below at how.

• Insulin promotes fat storage. It lowers insulin levels, promoting fat burning.
• Human Growth Hormone (HGH) supports muscle growth and fat burning. IF increases HGH levels significantly.

Also, gene expression can lead to diseases. This diet plan changes gene expression for longevity and disease prevention |

Yes, it sounds pretty scientific and all. But do these changes make you feel like a superhero? Not quite. Remember, while some hormonal changes can be beneficial, they’re not exclusive to IF.

5. Better Brain Health

There’s some buzz around intermittent fasting improving brain health. Animal studies from 2018 and 2021 suggest fasting could protect brain health and enhance cognitive function. The keyword here? Animal studies. Some research indicates it might aid in preventing neurodegenerative disorders like Alzheimer’s and Parkinson’s. But we still need more human studies to say this confidently.

So, we are pretty sure that you are convinced that it can’t only have benefits. As it has major downsides. But do you know lots of myths are roaming over the internet about this IF? Let’s quickly debunk them one by one.

Myths of Intermittent Fasting

So, squash some myths because why not?

Myth 1: Intermittent fasting is the Ultimate Weight Loss Solution

Well, we hate to break it to you. This is not reality. Sure, time-restricted eating plans can produce weight loss, but so does any diet that reduces calorie intake! Plus, studies suggest that a one-year period isn’t enough to conclude long-term weight loss via IF. So, if you think skipping breakfast will magically make you look like a ramp model, think again.

Myth 2: Anyone Can Do IF

Nope! IF is not for everyone. Those at risk include:

• Pregnant or lactating women
• Anyone under 18
• Individuals on medications that require regular meals
• People who have eating disorders

Consequently, assess whether IF is right for YOU before jumping on the craze.

Myth 3: Intermittent Fasting Lowers Diet Quality

Hold on! We are pretty sure that Dr. Michael Mosley would be devastated by seeing this claim. Because IF doesn’t tell you to avoid fruits, veggies, or carbs. Not what you eat matters, but when you eat it. It doesn’t mean gobbling extra-cheese nachos at 2 a.m. while binge-watching GOT. It’s more about setting an eating window, say, between 12 p.m. and 8 p.m.

Do You Need to Do Intermittent Fasting?

Now you have come to a crucial part of our discussion. There is some good evidence suggesting that an 8-hour sleep followed by a healthy diet and lifestyle is enough. Sufficient and efficient for reducing weight, particularly for individuals at risk of diabetes. Most importantly, if you have Type 1 diabetes, an eating disorder, or are expecting a child then intermittent fasting might not be the ideal option. Why not first get advice from a medical professional?
