My thoughts on this are that it could be part of a healthy diet, and if that is why you chose to drink these, then that is fine. If it is healthier than what you normally eat, you are making steps to improve your health. Hopefully that evolves into even better health of real food as opposed to liquid breakfast.
If you are just drinking breakfast to save time though, you do need to stop and ask why you can't spare 10 minutes to make a better meal. I know it is tempting to sleep an extra 15 minutes, but a few weeks of eating healthier, and you may find that when the alarm goes off, you are raring to go. You will find the time needed. If necessary cut something else, because diet is the #1 most important thing in your life. Fail at it, and you really won't have enough time. Breakfast shouldn't be the first thing you cut, but the last.
Still, if this is a step towards healthier eating, I can understand that we aren't always going to make the jump in one step, and if it is better than today's breakfast, and fits into your tracker ranges, then go ahead.
