Does it really matter if you eat fats, carbs and protein together in a meal besides breakfast. I've had a trainer tell me that this should only be done the first meal of the day. It's now 4:15 and I just had low-carb wheat toast (9g carbs with 15g of protein in 2 slices) with natural peanut butter and a protein shake. Is this really bad? I eat very clean, but does timing really matter that much? Thanks.
