In my practice I say 1-2 carbohydrate-rich meals a day. Say one high-carb meal if you really want to lose weight. Take carbs like bread, granola, crackers, rice, potatoes, pasta. The choice is yours when you take these. Some people like to eat only vegetables with fish/meat/chicken/vega in the evening. Then you could take your carbohydrates in the morning or afternoon. After all, you need these for a balanced healthy lifestyle. It provides energy!
Signature NG contains per 100 grams: 43.7 grams of carbohydrates, of which 17.3 grams of sugars. Translate to the portion you take. Will you take one tablespoon? Then you could also take a little rice in the evening. Do you take a good portion of 40-45 grams? Then count it to your carbohydrate meal for the day.
