Unpopular FACT: Artifical sweetners do NOT make you hungry

You’ve probably heard some version of the following:

"Artificial sweeteners make you hungry."
"Sweet taste without calories confuses your brain."
"They make you crave more sweets."
You've probably heard some version of these claims before. The problem? The data keep refusing to cooperate. A new study, "Acute and prolonged effects of sweeteners and sweetness enhancers on postprandial appetite sensations, palatability, and ad libitum energy intake in humans," examined exactly this question

If artificial sweeteners really increased hunger, cravings, or caused people to eat more later, this study should have found it. It didn't. Researchers found that consuming sweeteners and sweetness enhancers did not increase subsequent energy intake, did not meaningfully increase appetite, and did not lead participants to compensate by eating more later. In other words, the common claim that "sweet taste without calories tricks your brain into overeating" continues to lack support from actual human data.

This is a great reminder that just because a mechanism sounds plausible doesn't mean it translates into real-world behavior. Humans aren't Petri dishes, and while people love inventing scary stories about artificial sweeteners, the totality of evidence continues to show that replacing sugar with low- or no-calorie sweeteners generally helps reduce calorie intake and can support fat loss.

Your body isn't sitting there thinking: "Wait a second... that was sweet but not enough calories. Better order a large pizza." It doesn't work that way. This study showed people actually ate slightly less calories when consuming artificial sweeteners. This is in alignment with other studies demonstrating that artificial sweeteners decrease energy intake and reduce body fat in tightly controlled human RCTs (PMIDs: 40913681 & 39606579)

As always, test hypotheses against data, not vibes.

Gary and I discussed debating.

I agreed to:

✓ A moderator
✓ Recording it
✓ Posting on both channels

The debate never happened.

I’m still happy to do it.

Gary and I will both be at Eudemonia conference in November.

If you’d like to see a respectful discussion on hormones, cortisol, fasting, seed oils, exercise, and health claims by Gary, tag him below

[Layne Norton, PhD @BioLayne]

I'm your huckleberry...

Of course you'll duck this debate just like you did the 2 other debates you agreed to with me, then backed out of

First off, you contradict yourself via your proposed mechanisms without even realizing it.

Coffee elevates cortisol acutely but does not affect long term cortisol levels. Acute changes in cortisol reflect fuel mobilization responses, not anything sinister

Then you contradict yourself by saying 'no movement' because exercise is well known to elevate cortisol acutely.

So if coffee only elevates cortisol acutely, but so does exercise, how is one bad but the other one good?

Answer: You have no clue because you only care about creating clickbait... not accurate information

[Gary Brecka @thegarybrecka]

Debate me:

Your “healthy” morning routine might be wrecking your hormones.

- Coffee on an empty stomach
- No sunlight
- No movement

That’s cortisol chaos.

[Layne Norton, PhD @BioLayne]

@anton75960 Nope but thanks for the compliment

336kg / 741lb deadlift at age 44 lifetime drug free for an American Record and unofficial M1 World Record deadlift (so what if it was broken 1 minute later lol)

Powered by aspartame and seed oils 🤣

@YourCoachDavid Absolutely I think cardiorespiratory fitness is very important

[Layne Norton, PhD @BioLayne]

People like @bulletproofexec & @thegarybrecka want you to believe that biohacking must be complicated & expensive

This is the biggest scam in wellness

Biohacking is NOT:

hydrogen water
grounding mats
red light therapy
exotic supplements
analemmas (water wands)
overpriced tests

[Layne Norton, PhD @BioLayne]

These people profit when they convince you that you are helpless & the solutions are expensive & complicated

I'd rather show you that you are resilient, adaptable, & capable of doing HARD things that get you results

That is why I walk the walk. I'll be doing this challenge WITH you

Hit the link & let's me show you what REAL biohacking is

This is not a cookie cutter challenge where you get a PDF generic program. This is custom to you with REAL support

It's crazy what @ConsensusNLP is doing!

[Consensus @ConsensusNLP]

Launch Week Day 2: the Consensus Research Agent.

Consensus can now complete complex research tasks through multi-step tool calls.

One prompt in. A full research workflow out.

[Layne Norton, PhD @BioLayne]

@JMannisi Acute =\= long term outcomes

[Layne Norton, PhD @BioLayne]

612 lb squat at 13 days out from Masters Nationals. A lot of fatigue at this point but that’s to be expected. Almost 2 years since I competed and I’m ready to get in a dogfight

44 years old… but not obsolete 😈

[Layne Norton, PhD @BioLayne]

Not only have I been incredibly impressed with the product from @ConsensusNLP which is second to none, I have been unbelieveably impressed by their execution at all phases

I can't wait to see what they do next. Incredibly honored to be a scientific advisor for them

[Consensus @ConsensusNLP]

Today, we're announcing $30M in new funding to build the AI OS for Research.

2.5M researchers start their work with Consensus every month. Their work is the foundation that all progress is built upon.

We could tell you our story. We'd rather they did👇

Influencer popularity, likes, and clicks does NOT make something a treatment plan

My mother is not alive because she ignored oncology.

She is alive because she followed the best evidence available.

That does not guarantee survival.

But it gives you the best odds.

And when the stakes are life and death, odds matter

[Layne Norton, PhD @BioLayne]

12 years ago, my mother was diagnosed with “incurable” multiple myeloma (MM).

At the time, median survival was roughly 4–6 years.

She listened to her oncologist.

She followed evidence-based treatment.

She is still here 12 years later.

Thriving.

[Layne Norton, PhD @BioLayne]

The standard of care does NOT mean blind obedience

Ask questions.

Get a second opinion.

Understand risks and benefits.

Ask about side effects & alternatives

Ask what happens if you wait.

My mom did all these things. It was welcomed & encouraged by her doctors. It helped her & them
