No its not, thats the perspective of sedentary person who sees somebody running their 5k every day and is eager to give up before even starting. Once you grok some trivially simple stuff (macro and micronutrients), few extremely trivial requirements (enough good sleep, stay away from sweet stuff in principle which may be hard in beginning but gets much easier over time, eat to stave off hunger and not to feel full, eat less in the evening), you are at least 90% there which is already enough. You really don't need to study constantly labels, you already know whats good and bad and its an effortless background process in the back of the mind. It really is trivial and very quick to grok. The hard part for many is discipline, thats a mind game everybody has to fight with themselves and find ways how to manage it without frustrating oneself constantly, and thus give up eventually on whole effort. People often compensate some deep mental issues, ie anxiety with overeating or eating junk food. Obviously this needs to be tackled first if any long term success can be claimed. Also, for parents, please don't condition your kids on sweet stuff as some sort of reward. If you have to, use some great fruits like forest fruits and not cakes, ice cream etc. You are not being a good parent at all by doing this, just conditioning them mentally that sweet junk is something special, a prize deserved, which creates pretty bad mental patterns for rest of our lives.
