Why? My sugar-free protein bars say exactly how much calories they are. I also eat some zero-calory fiber (psyllium), vitamin and minerals pills, a spoonful of fish oil, feel great and loose weight :-)
It is harder to count calories when you make your food at home from fresh ingredients, or go out to restaurants. Not that you can't, but it is both harder and less accurate.
Mostly. I believe the other things I eat per month account for the caloric intake an average person takes in a day or two and can this way be ignored.
I used to eat a lot of cookies until November but stopped as soon as I noticed (at the clothes store) I gained some belly fat. I don't want to switch my clothes size. I firmly believe any visible increase in waist size (unless attributed to muscle growth) is a strong sign I must lose some weight (by reasonably healthy means - I would hesitate to take incretin mimetic drugs, they seem risky).
For how long are you doing that? I'm skeptical that could be healthy as you would be missing a lot of essential nutrients like fiber, vitamins, minerals. Also the palm oi in the proteins bar being the only source of fat will imbalance your lipids. Concentrated whey protein powder (without added carbs) are cheaper and better than protein bars though it still is a supplement and not a replacement for real food. But you can mix it with oats, nuts, chia, fruits to improve taste and nutrition.
