“Fruit based diet” is ambiguous. Just like so many of the other terms we use in nutrition. Ask 10 people to create a “fruit based diet” and you will get 10 unique menus. Same with terms like; low carb, high carb, plant based, clean, keto, healthy, balanced, etc.
What I see here is one, single, self proclaimed fruitarian (if that’s even true) that may be perceived as healthy, based on subjective perceptions of video analysis. Conversely, there are dozens of fruitarians and raw vegans that look objectively terrible and have admittedly ruined their health.
After studying and coaching nutrition for close to two decades now, I understand that nutritional decisions should never be made, based on observations of others, particularly “online” observation. It’s a complete gamble as to the totality of truth being presented, interpretations, personal biases, etc. Even if an individual is being as transparent and precise as possible, how much overlap there may be in that exact moment in time of an individuals physiology and the physiology of the person they are deciding to emulate, is a complete crap shoot. On top of that, not everything is about food. It’s impossible to define a “healthy” diet, without consideration of all aspects of an individuals environment.
Static concepts are appealing to our minds, because they offer the ability to “check boxes” and move on to other things. I think that’s ultimately what people are searching for when they are trying to get “healthy.” If I just figure out how to eat, then I can do all the other things I want to do. But health requires a dynamic life, and therefore dynamic nutrition. Defining diets, or even individual foods, as good or bad is grossly myopic.
This is obviously an overreaching post in relation to the OP. But it’s here, and maybe it will help someone make the choice to stop looking for their health on the internet. It isn’t here.
Cheers.
