I've read that cutting carbs is unhealthy, but all my friends are losing weight by doing it. Why shouldn't I?
You will be able to better maintain your weight loss, if you don't have to permanently eliminate or restrict a single food group, Low-carb diets are designed for short stints because your body simply cannot function without carbohydrates for very long.
To be clear, carbs are an important macronutrient to a balanced diet. Diets that have this as their weight loss technique are appealing because they promise quick results, but studies show that after 12 months, they provide no greater weight loss benefit than a typical reduced-calorie, low-fat diet. Slow and steady weight loss is much easier to maintain for life.
