This is what you do. Get the box and chuck it in the bin. Instead prepare alternative snacks. Vegetable sticks (mushroom, capsicum, snowpeas, cauliflower, carrot, cucumber) and homemade hummus, minus oil, or greek yoghurt mixed with garlic and parsley.
You also might be restricting your carbs too much, and then crave sugary granola and cereals. In that case try a fruit. Get the cereal and granola out. Replace it with bran, no added sugar with freshfruit, like banana, strawberries.
Don't know if that'll help.
