Net carbs (total carbs - fiber) in your serving
Protein, fat, and fiber slow carb absorption, lowering the effective GL
Why Glycemic Load Matters for Fat Loss
High-GL meals cause rapid blood sugar spikes, triggering insulin release. Insulin inhibits fat burning and promotes fat storage. The subsequent blood sugar crash increases hunger and cravings 2-3 hours later.
Lower-GL meals provide steady energy without the insulin roller coaster. Our metabolic flexibility research shows that managing GL improves appetite control, reduces cravings, and maintains fat-burning throughout the day.
Practical GL Guidelines
- Per meal: Aim for GL <15 for most meals
- Daily total: Target <80 GL per day for fat loss
- High-GL timing: Reserve high-GL foods (fruit, rice, potatoes) for post-workout when insulin sensitivity is highest
- Mixed meals: Always pair carbs with protein/fat to lower effective GL
