  • In the early 1960s

  • a new kind of beverage took the stage.

  • It wasn't a new shape or a 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 eight-year-long study, between 1979 and 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 the meal may sound like

  • a tasty calorie free alternative to plain water,

  • the growing body of research is starting to find

  • that this may be the worse 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 10s to 100s 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 just stick to water.

  • Got any friends obsessed with diet soda?

  • Share this video with them and thanks for watching.
