1. Why Diet Is the #1 Factor in Type 2 Diabetes
1 in 10 adults has type 2 diabetes. Diet is your most powerful tool.
According to the CDC, over 37 million Americans live with diabetes, and 90–95% of them have type 2. Numbers are rising fast, especially since COVID-19 changed how we live, eat, and move.
And healthcare isn’t cheap. A doctor’s visit can cost $200–400, a registered dietitian $100–150 per session—even with insurance, copays add up.
That’s why smart dietary choices are not just helpful—they’re essential.
The American Diabetes Association states that proper diet alone can reduce A1C by 1–2%—the same as taking a diabetes medication.
Modern Lifestyle Pitfalls
-
Heavy reliance on fast food (3–4x/week)
-
60%+ of calories from processed foods
-
Huge portion sizes at restaurants
-
Excessive sugar intake: ~17 teaspoons/day
The good news? Better food choices can reverse this trend—starting today.
2. How to Choose the Right Low-Carb Foods
You don’t need to overcomplicate it. Just focus on these two metrics:
① Glycemic Index (GI)
-
Low (≤55) = slow blood sugar rise ✅

-
Total Carbohydrates: 20g
-
Dietary Fiber: 8g

Net Carbs: 12g
✅ For type 2 diabetes: Aim for 15–30g net carbs per meal
