A 50g serve of 180 is approximately 50% protein, 25% fat & 25% carbs. Included in this of course is the vitamins minerals and fibre. Of the 25% of carbs a large percentage is non-digestible fibre, so you could say that the actual carb content (that which effects blood sugar) could be as low as 15%. Naturally, what you blend with 180 will effect this ratio. Milk or water... Banana or avocado etc...
