Therapeutic Carbohydrate Restriction (TCR)

Lower-glycemic nutrition can improve glycemic control, triglycerides, and satiety in insulin-resistant patients.

Why carbohydrate quality and quantity matter

Refined carbohydrate load drives post-meal glucose spikes in many patients with insulin resistance. Therapeutic carb restriction lowers glycemic burden while emphasizing nutrient-dense foods.

Downstream conditions

Obesity and insulin resistance

Many chronic conditions cluster around the same upstream metabolic load. Click any condition to open its simple-language resource page.

Practical template

Three-Step Meal Decision Algorithm

Step 1: Pick a protein first

Example options: Eggs, fish, chicken, lean beef, tofu, Greek yogurt, or cottage cheese.

↓ Then move to Step 2

Step 2: Add non-starchy vegetables and a side

Example options: Leafy salad, broccoli, cauliflower rice, zucchini, peppers, cucumber, avocado, olives, or nuts.

↓ Then move to Step 3

Step 3: Pick a low-carbohydrate drink and dessert

Example options: Water or sparkling water, unsweetened tea or coffee, berries with plain yogurt, sugar-free gelatin, or a small square of dark chocolate.

Sugar infographics

Dr David Unwin's sugar infographics

Low Carb GP Dr David Unwin has produced practical infographics showing how typical portions of common foods can create a surprisingly large blood glucose effect, often illustrated as teaspoons of sugar.

What is individualized

Target carbohydrate ranges should match medication use, diabetes severity, kidney status, and patient preferences.

Monitoring

Track fasting glucose, post-meal response, blood pressure, and subjective satiety. Adjust progressively instead of making abrupt unsupervised changes.
