What Too Much Diet Soda Does To Your Body And Brain

What Too Much Diet Soda Does To Your Body And Brain

Artificial sweeteners are one of diet soda’s main ingredients. But studies have shown that the artificial sweeteners within diet sodas can cause a series of health problems. We decided to take a look at what happens to the body when you only drink diet soda. Following is a transcript of the video.

In the early 1960s, a new kind of beverage took the stage.It wasn’t a new shape, or color, or flavor. No, this was diet soda. And It. Was. Awesome.

With fewer calories and less sugar, diet soda promised to be a healthier alternative to regular soda. But like most promises in life that sound too good to be true, it probably is.

Can you tell the difference between a glass of regular and diet soda? Turns out, neither can your body. And that’s where the trouble starts.

Until recently, everything we ate contained some amount of calories. When we ate something sweet, for example, the brain sent signals to our pancreas. Which started producing insulin, that stored the sugar molecules in our cells for energy.

So, when we drink diet soda, the sweetness tricks our body into thinking it’s real sugar. But when those energy-packed calories don’t arrive, the insulin has nothing to store.

Scientists think that repeatedly tricking our body this way could explain why study after study keeps finding the same thing: that drinking diet soda is associated with metabolic syndrome. Metabolic syndrome is a mix of conditions that includes: increased blood pressure, high blood sugar, and weight gain. Which can increase the risk of diabetes, heart disease, and stroke.

In fact, one study found that diet soda drinkers had a higher risk of stroke and dementia than regular soda drinkers. And for another 8-year-long study between 1979-1988, participants who started out at a normal weight and drank an average of 21 diet beverages a week faced DOUBLE the risk of becoming overweight or obese by the end of the study, compared to people who avoided diet beverages completely.

And while drinking diet soda with a meal may sound like a tasty, calorie-free alternative to plain water, a growing body of research is starting to find that this may be the WORST time to drink it. Because the fake calories in the diet soda could ultimately disrupt how many of the real calories we metabolize. Potentially leaving excess calories behind that we then store as fat.

Another issue could be the fact that artificial sweeteners in diet sodas can be tens to hundreds of times sweeter than sugar. So when we taste it, our brains anticipate more calories than what we give it. It’s like when you go to a party expecting loads of food and you end up with a handful of veggies and vegan cheese. You’re left unsatisfied and hangry. In the same way, artificial sweeteners can leave our brains wanting more, which studies have shown leads to increased appetite, and potential weight gain, in fruit flies, mice, and humans.

So if the reason you’re drinking diet soda is to drop a few pounds, maybe stick to water.

    I’m type 1 diabetic so how can this affect me?

  2. GamerBomb on January 15, 2023 at 4:42 am

    Watching this makes me want to drink water.

  3. DX- DRAGON on January 15, 2023 at 4:42 am

    Ya if it’s zero calories your not gaining weight from it because it’s about how many calories you consume if you drink diet coke and what you eat doesn’t change your not gaining weight

    ‘What too much diet soda does to your body and brain’

    They both tell me that it taste _GOOOOD_

  5. EMS 76 on January 15, 2023 at 4:43 am

    Bunk science and cherry-picked science does more harm than good

    I’m surprised a channel called "Science Insider" would play it so fast and loose with a topic like this – one where the scientific data is lacking and disputed.

    I’m curious if diet sodas affect the viscosity of our blood like energy drinks do…

    I’ve dropped 200+ pounds while drinking diet soda. Drink it with a meal or just on it’s own. I’m pretty good at limiting what I eat but sometimes i need that fizzy soda to calm down my cravings. Blood work comes out fine. I was prediabetic and now im not. I also love diet coke cause it will give me that caffeine i need to start my day and i hate black coffee. So i say this is bs. If you’re on a calorie deficit diet and need a little help with cravings then diet soda is a great tool.

    This video is unscientific and sensationalist

  12. Chen Xixia on January 15, 2023 at 4:53 am

    We are happy for the video

  13. Chonokhan on January 15, 2023 at 4:53 am

    Everything in moderation. The primary drink of people should be Water. But I think if you are obese or have diabetes, you should stick to non-sugar drinks until you can cure you diabetes through exercise and eradication of all the sugars in your body.

  14. Lieutenant Dark on January 15, 2023 at 4:54 am

    You could cite your evidence 🙂

  15. Maximus on January 15, 2023 at 4:55 am

    This video is bad

  16. Hoshie on January 15, 2023 at 5:01 am

    I need to show this to my addict diet coke family members, they drink it like it’s water. I swear my brother doesn’t even take a sip of water but drinks these diet sodas.

  17. CAT_SAYS_NO on January 15, 2023 at 5:01 am

    I drank ONE diet coke and had a upset stomach like never before, and I rarely get upset stomachs.

  18. Daily talk with Colton on January 15, 2023 at 5:01 am

    Nope not real not real 😭

  19. Simbacu on January 15, 2023 at 5:04 am

    A lot of the sodas are packed with artificial crap flavours that can have very bad consequences but when it comes to Pepsi or cola I think there’s a little bit of a difference kind of like there’s 3 types for those two so you have the full sugar Pepsi or coke then they made diet which they say has no sugar, it does have Sugar just very little of it but still real sucrose like glucose there still phicically some in it, but then there’s coke zero and Pepsi max, this is where it’s dangerous there LOADED with artificial sugar substitutes like artificial sweeteners, basically sweetex if you think of it that way

  20. Liam Lewis on January 15, 2023 at 5:09 am

    I’ve drink pepsi max in my 4 hour eating window of intermittent fasting like constantly, every single day. All my bloods our perfect and I’ve lost 3 stone this year alone. It definitely hasn’t hindered my weight loss one single bit. And I don’t rely on it either. it just depends on the individual if it is going to spike your insulin or not. So many studies have shown this. And no diet drink with raises blood sugar either 🤷‍♂️

  21. Leo Fisher on January 15, 2023 at 5:09 am

    This is so misleading 🙁 A lot of studies contradict these findings and they didn’t mention reverse causation, which could account for some of the links to poor health.

  22. chester82gtstang on January 15, 2023 at 5:09 am

    lol 21 a week! holy crap I want to have like 1-2 a week as a treat.

  23. Grimazzi Penn on January 15, 2023 at 5:09 am

    Diet soda drinkers cant handle the truth. Including myself.😂

  24. Joshua McGregor on January 15, 2023 at 5:10 am

    That’s why I tend to mix them to like 45% diet 55% sugar

  26. Simbacu on January 15, 2023 at 5:15 am

    The issue here is that our bodies are kind of designed to deal with sugar, the artificial sweetener on the other hand tastes sweet the body responds by creating insulin cause it thinks its getting glucose when in a matter of fact it’s not, so it wastes insulin, and either uses up all what’s left in the body making you lose a little weight, but what can then happen is the body over produces insulin which can eventually lead to diabetes or something similar or the symptoms or lack of energy but that’s not the worst part, the artificial chemicals replacing the sugar can build up in the liver and limit its functions to the point it actually causes a type of liver disease which can be fatal

    I call bullshit. Been drinking diet soda for 30 years and a lot of it. Perfect blood sugar, lipid profile and blood pressure and no weight problem. If I had regular soda all these years With how much I drink I’d be dead or close to it. These people are morons

  29. starlite556 on January 15, 2023 at 5:17 am

    My headaches at the base of my neck went away when I stopped drinking diet soda.

    One Major Effect of Drinking Diet Soda Every Day, Says Science
    In many ways, diet soda is a healthier alternative to its sugar-filled counterpart. It’s lower in added sugar and calories, both of which contribute to obesity and chronic health issues like type 2 diabetes and heart disease. However, it’s still not the perfect solution. In fact, you may be better off just choosing a low-sugar soda alternative over one that’s completely sugar-free. Here’s why.

    “Stick with water” smart advice

  34. VV illehelm on January 15, 2023 at 5:22 am

    Hey "Science Insider"… correlation does not imply causation.

  35. Kenny Powers on January 15, 2023 at 5:22 am

    Technically real soda is worse, but I can’t taste the difference lol

  36. hi on January 15, 2023 at 5:24 am

    Then… logically chewing gum, braeth mints and brushing your teeth 1 minute is also bad for you?

  37. Vic Blanco on January 15, 2023 at 5:25 am

    Dubious science produce this fake news , MD Seesma Jazmín head of the medical department at Stanford states the opposite.. And I do believe in her

  49. survivalist on January 15, 2023 at 5:37 am

    What happens if you drink sugar-free soda everyday?
    A growing body of evidence suggests that diet soda consumption correlates with an increased risk of a wide range of medical conditions, notably: heart conditions, such as heart attack and high blood pressure. metabolic issues, including diabetes and obesity. brain conditions, such as dementia and stroke.3 days ago

  50. Davide Uguccioni on January 15, 2023 at 5:40 am

    Funny cause I drink literally everyday and have great blood pressure and 55 BPM on rest being 26 years old. 0 alcohol, 0 drugs, 0 smoking.
