If you are craving sweetness from diet coke, just drink another diet coke 😂

[Ouellemancan]

I bought into this diet soda is evil myth for years and have been avoiding it because of this, thank you for bringing this to the light Layne! I just finished my Diet Coke also I am using carbon diet coach and I must say I love how you display the total calories left on the dashboard so as long as I hit my protein target I can lean heavier into carbs some days and fats others but still be on track as long as I don’t go over my calorie budget.

The guy talking was Dr Mike! Oh no! He’s a real doctor (family medicine) in New York. Always find it really disappointing when we get misinformation from actual doctors. BTW, I do drink Coke Zero on the regular!

[klocugh]

There are two actual problems with diet soda:

1. Price
2. Bad for teeth due to acidity

Hey Layne,
It would be nice if you do a video about different artificial sweeteners and their research based findings.

[danielswart]

Yep, I'm convinced it was the zero calorie soda and not the candy bar, large pizza, and burritos that made me fat.

I drink diet Pepsi with 1 or 2 of my meals a day. The weight is flying off of me, and the soda scratches that itch when I need something with a bit more punch than the 60-70oz of water I drink a day. If I'm really craving it, I'll drink another. But I really never have gotten a concrete answer to "why is diet soda bad for me and/or bad for my weight loss?". I'm at a loss really, it's almost like people think it's too good to be true so they are just kinda saying "that stuff CAN'T be good for you" like there's some magical evidence out there that shows this even though no one has presented me with it yet.

The Impact of Artificial Sweeteners on Body Weight Control and Glucose Homeostasis

Conclusion and Perspectives
The scope of this review was to review the physiological effects of artificial sweeteners on body weight control and glucose homeostasis, and to identify the controversies of the existing evidence between different artificial sweeteners surrounding their use. Although artificial sweeteners maintain the same palatability as natural sugars, the metabolic routes are different. Therefore, artificial sweeteners affect body weight and glucose homeostasis differently compared to natural sugars via underlying physiological processes comprising the gut microbiota, reward-system, adipogenesis, insulin secretory capacity, intestinal glucose absorption, and insulin resistance. The gut microbiota, in particular, may play a major role in the physiological effects of artificial sweeteners on body weight regulation and glucose homeostasis. There is mechanistic evidence that artificial sweeteners may induce gut microbiota dysbiosis, by altering the gut microbiota composition and function. Although different physiological processes are involved in the effect of artificial sweeteners on metabolic health, meta-analyses of RCTs or RCTs and prospective cohort studies suggest that artificial sweeteners may have a neutral effect on body weight and glycemic control, respectively, or may have a beneficial effect on long-term body weight regulation. Even though the majority of human studies report no significant effects of artificial sweeteners on body weight and glycemic control, it should be emphasized that the study duration of most studies was limited. Furthermore, unlike rodent studies, long-term studies investigating the underlying physiological effects body weight control on metabolic health of artificial sweeteners in humans are scarce and therefore warranted. Currently, within the European H2020 project SWEET (www.sweetproject.eu), a human multicenter study is ongoing which aims to investigate the use of artificial sweeteners within the context of a healthy lifestyle on body weight maintenance after weight loss and on metabolic health risk. Notably, artificial sweeteners are metabolized differently and may not all elicit the same metabolic effect as, for instance, components may affect the gut microbiota composition directly and others are easily digested and absorbed. Not all studies investigating the effects of artificial sweeteners on body weight control and glucose homeostasis take into account the different metabolic pathways of distinct artificial sweeteners. Therefore, human data on the effects of distinct artificial sweeteners are limited or lacking. The difference in metabolic fate of artificial sweeteners may underlie conflicting findings that have been reported related to their effects on body weight control, glucose homeostasis, and underlying biological mechanisms. Therefore, extrapolation of the metabolic effects of a single artificial sweetener to all artificial sweeteners is not appropriate.

In this regard, future studies should consider the metabolic pathways of different artificial sweeteners. Further (long-term) human research investigating the underlying physiological pathways of different artificial sweeteners on microbiota alterations and its related metabolic pathway is warranted to evaluate the potential impact of their use on body weight control and glucose homeostasis. Ultimately, it would be interesting to elucidate the impact of initial microbiota composition as a predictor for the response to artificial sweeteners in humans.

I’m really glad to hear these results. I eat fairly healthy food, but I have the occasional diet soda to satisfy my craving for something sweet tasting. I don’t find that it makes me crave other sweet treats or increase my appetite afterwards.

[rontiemens]

Layne, thanks for your videos. Sometimes I do not like what you say, usually because it shows I have either been wrong or at least hasty. So the evidence you cite has changed my mind in some things. You also have the personal results which are quite compelling. Thanks.

Best diet drink ever made: Mountain Dew Zero Sugar. Tastes exactly like regular Mountain Dew, with 0 calories and 50mgs of caffeine. Basically no downsides, since switching to it I have 1 coffee in the morning, 1 Mountain Dew Zero Sugar at lunch, usually dont need anymore caffeine than that and it solves for my sweet cravings.

[Sabeine]

As a fitness coach myself, I advocate for diet sodas. I'm taking myself through a cut right now and have lost 8 lbs this month while increasing my diet soda intake due to its satiating effects. Still lost the 8 lbs though...

[qT_p]

I would imagine that going from water to any type of soda isn't exactly "healthier" but not for any of the reasons he outlined.

[MckeyD]

Weight isn’t the only health marker, what he’s saying is don’t start drinking diet soda if you’re already drinking water. It’s hard to disagree with that, regardless of if the science on the affects the micro biome have aren’t clear in either direction; diet soda is more than just artificial sweeteners

[katiekleinbeck]

Isn’t that guy Dr. Mike in the clip?! Come on Dr. Mike! Of all people he should know better 🙄

[ryanhailey]

Hey layne, I would love to see a breakdown of NNS and their potential effects on testosterone, fertility, and hypertrophy. There seems to be different effects between sweeteners. i.e stevia's metabolism vs. Sucralose's metabolism. Love the stuff you put out man, looking forward to continued research in this area

[boatmandan]

Dr mike who could you BS us! Thats the problem with people going outside of their lane and still assuming they know what they’re on about. Good doc doesn’t equal good nutritionist/researcher.

[AJ-fbpk]

It's really unfortunate to see general physician doctors spill out garbage information with no basis and ignoring all researchs done by actual nutritional scientists.
And of course people will listen to the "handsome" influencer Dr. Mike instead of nutritional scientists.
