A Thought to Sit With: If It’s Not a HELL Yes, It’s a No

I was telling my sister (sista!) recently how much more I’ve been saying no lately—to plans, invitations, even opportunities.

It reminded me of something worth sitting with:

Every yes is also a no to something else.

Your time. Your energy. Your family. Your health. Your rest. Your joy.

When you know what matters most to you, the decisions get a little easier.

So before your next automatic “yes,” ask yourself:

Is this a HELL yes?

If it isn’t, maybe your answer is already there.


Zinc and Type 1 Diabetes: What Should We Know?

Zinc may play a bigger role in metabolic health than we give it credit for.

A 2024 systematic review and meta-analysis of 23 randomized controlled trials found that zinc supplementation was associated with improvements in fasting blood glucose, A1C, CRP, triglycerides, and total cholesterol in people with prediabetes or type 2 diabetes.

Important: This study was not conducted in people with Type 1 diabetes, so we can’t assume the same outcomes apply to T1D.

But it highlights something I think is especially important for those of us living with Type 1 diabetes:

Blood sugar management doesn’t exist in a vacuum.

Nutrition status, sleep, stress, hormones, movement, and micronutrients can all be part of the bigger metabolic picture.

Why Does Zinc Matter?

Zinc is an essential mineral involved in hundreds of processes throughout the body. It’s particularly interesting for metabolic health because of its involvement in:

  • Insulin storage and secretion
  • Insulin signaling
  • Antioxidant defenses
  • Immune function
  • Cellular health

Does that mean everyone with Type 1 diabetes should take a zinc supplement?

No.

Your baseline zinc status matters, and more isn’t always better. Excessive zinc intake can interfere with copper absorption, which is one reason I prefer a personalized approach rather than blindly adding supplements.

My takeaway: Managing Type 1 diabetes isn’t only about counting carbohydrates and dosing insulin. Looking at the bigger picture—including overall nutrition and micronutrient status—matters, too.

Read the 2024 systematic review on PubMed.


A Quote I’m Reflecting On

“Anyone who encourages you to move your body, eat well, and grow as a person is someone you should never let go of. But, most importantly, be that person to yourself.”

— Shewins.co

That last line is the one I want to leave you with:

Be that person to yourself.


Looking for a More Personalized Approach to Type 1 Diabetes?

Type 1 diabetes is about so much more than insulin and carbohydrates.

In my private coaching, we look at the bigger picture—nutrition, blood sugar patterns, routines, movement, metabolic health, and the other pieces that can influence how you feel and manage T1D day to day.
