Just don’t jump yourself into an irrational fear of carbs ok?
I have to ask myself this question all the time because I’ve definitely struggled a lot with being over restrictive when it comes to food. If a new habit I’m looking to put into practice is really just feeding that restriction and fear then I put a pin in it while I look deeper at whether I REALLY need it.
I’ll get regular comments from women asking “what about glucose spikes???” whenever I talk about carbs. And it’s always written exactly like that - frantically and fearfully.
Glucose and cortisol spikes are a normal part of biology. Did you know they’re also happening when you’re doing a slow and steady weights workout?
I just wanted to provide a little more context to the message in this post.

![Your Brain on AI: How to Build Your Memory Muscle Before You Borrow It with Jim Kwik
For over 30 years, @JimKwik has coached Hollywood, professional athletes, political leaders, and Harvard University on how to learn faster and think sharper — and in this episode, he tackles the question sitting underneath so much of modern life: what happens to your mind muscle when every cognitive task gets handed off to ChatGPT or Claude?
The good news: your brain, like your muscles, adapts to the demands placed upon it at any age or stage. Jim explains why frustration and failure aren’t obstacles to brain training, shares his personal top ten list of brain-building habits, ranging from racket sports to language learning and volunteering. He also delves into an MIT study examining the impact of ChatGPT and introduces his own framework for using AI as a genuine cognitive partner, rather than a replacement for human brain power.
