Some people mindlessly eat carbs at random times of the day, often without realising how much they are consuming.
If you find it difficult to plan and make meals without smashing your carb allowance a simple solution is to replace grains (rice, bread, pasta and other starchy carbs) with greens (spinach, kale, watercress, broccoli, green beans).
This simple change will also increase your daily fibre intake and keep you satiated for longer.
