Why sugar and simple carbs worsen ADHD

For this last episode of ADHD-ish during ADHD Awareness Month,  host Diann Wingert welcomes Alan P. Brown, acclaimed ADHD coach and creator of the ADD Crusher program, for a candid and practical conversation about the everyday habits that make ADHD more challenging. 

Focusing on making ADHD easier to manage (and avoiding the traps we so often fall into), Diann and Alan break down what really sabotages our brains and share actionable tools to turn things around.

Alan shares practical tips and science-backed insights on why sugar and simple carbs can sabotage focus, how movement (not just "exercise") is essential for managing ADHD, and why consistent sleep hygiene is often the missing link for better mental clarity. 

They also get real about the seductive pull of screens, the pitfalls of "revenge bedtime procrastination," and how to set up healthier habits even if you struggle with planning ahead.

Guest Bio: Alan P. Brown

Alan P. Brown created the award-winning ADD Crusher™ video program for ADHD teens/adults. Undiagnosed for decades, his untreated ADHD manifested in underachievement, substance abuse, and worse. 

Once diagnosed, he found it difficult to learn coping strategies from books, so he researched his own evidence-based “brain hack” strategies to fuel a successful advertising career and two start-ups.  In addition to his successful coaching program, Alan is also a best-selling author and a conference and TEDx speaker.
