Frequently Asked Questions
How many carbs should I eat per day?
Standard recommendation: 45-65% of calories from carbs (225-325g for 2000 cal diet). Active people may need more. For weight loss, moderate carb (30-40%) or low-carb (20-30%) can help. Keto is under 50g/day. Match carbs to activity level.
What is the difference between good and bad carbs?
Complex carbs (whole grains, vegetables, legumes) digest slowly, providing sustained energy and fiber. Simple carbs (sugar, white bread, candy) spike blood sugar quickly. Focus on whole food carbs with fiber; limit added sugars and refined grains.
How does low-carb affect weight loss?
Low-carb diets reduce insulin, increasing fat burning. Initial weight loss is partly water (glycogen stores). Research shows low-carb can be effective for weight loss, especially when protein is adequate. Sustainability matters most long-term.
Should I count net carbs or total carbs?
Net carbs = Total carbs - Fiber (- Sugar alcohols). Net carbs affect blood sugar more directly. Keto dieters typically count net carbs. For general health, focus on getting enough fiber (25-35g) while moderating total carbs.
When should I eat carbs?
Timing matters for athletes. Before workout: 1-4 hours prior for energy. After workout: within 2 hours to replenish glycogen. For general health, spreading carbs throughout the day maintains steady energy. Some prefer fewer carbs at night.
