From the founder

Miguel Ramos

I'm Miguel Ramos, founder of Evidence-Based Nutrition. I wrote this guide with the people above so you get the science, not a sales pitch. Request the guide at the top of this page and I'll send it straight to your inbox.

WHAT IS INSIDE THE GUIDE

Most people are given vague instructions on what not to eat.

This guide shows you what the research actually says, in plain language you can use this week.

The myths, settled

Carbs, fruit, and keto, and what the research really shows about each one.

Why it is not just sugar

How insulin resistance drives high blood sugar — and what that means for what you eat.

What your numbers mean

A1C, fasting glucose, and the prediabetes ranges, explained in plain English.

The Mediterranean way

A whole-food approach shown to support steadier blood sugar and a healthier A1C.

Where to start

The right small changes in food and movement and their big impact to your results.

Every claim cited

A full reference list, so you can check the science for yourself.
WHY THIS GUIDE IS DIFFERENT

Social media content about insulin resistance is full of  diets that pick a side.

This is neither.

Evidence first

Every claim is tied to peer-reviewed research, with references you can check.

No cold turkey

You don't need to give up any of the foods you love. It is about balance, not elimination.

No extremes

Whole-food Mediterranean eating that can be applied to any cuisine — not keto, carnivore, or strict vegan.

With your doctor

Built to support the care from your physician and not replace it.
