Common mistakes when lowering HbA1c and fasting blood sugar include ignoring glycemic index over calories, inconsistent monitoring, and extreme restrictions leading to rebound spikes. These errors hinder 0.5-1% HbA1c drops achievable in 3 months with proper habits.
Top Pitfalls
-
Calorie focus sans GI: High-GI carbs spike FBS despite low calories.
-
Late dinners: Night eating raises dawn phenomenon.
-
No post-meal activity: Missing 10-min walks fails 20-30% spike reduction.
-
Over-restriction: Crash diets cause metabolic adaptation, rebound.
-
Skipping sleep: <7h elevates cortisol/FBS 10-20 mg/dL.
Table: Mistake vs. Fix
| Mistake | Impact | Correction |
|---|---|---|
| Late high-carb meals | +30 mg/dL FBS | Eat by 7 PM, low-GI |
| Inconsistent testing | Miss trends | Daily FBS log |
| High fat intake | Insulin resistance | <30g fat/day |
| No exercise timing | Poor uptake | Calf raises post-meal |
Regular HbA1c verifies progress.
