I don't understand why the folk of HN have felt your post needed downvoting. Thank you for your anecdote. For several years I made a daily "meal replacement" smoothie. It was all whole foods, except for whey protein powder, including various greens, spices, nuts, seeds, etc. I varied it a little, including or excluding certain ingredients over the week. It covered my breakfast and lunch every week day. It was simple to make in the morning before work, because it became a habit. I knew that every day I was getting a huge range of healthy, whole food ingredients (albeit pre-chewed). I would additionally have a snack or two at work, and in the evening I'd cook something, but I felt no pressure to ensure that meal was nutritious. I could have pasta, with a bit of garlic and butter for example - which I love, but isn't very nutritionally dense. I was super, super healthy during this time. In very good shape. I eventually stopped when we had our first child and I couldn't always use the blender at the appropriate time (sleeping child), and I since just got out of the habit.
