Has anyone tried the mono diet?

I had to research what the mono diet was and here in a nutshell is an explanation.
“The other approach to this diet is eating mono meals, or eating one food, macro nutrient, or food group at each meal. ...
“Then for lunch, you might only eat fruit, and then for dinner you may only eat vegetables.” There’s also a mono raw diet, in which you can eat raw fruits or veggies for any meal..”

See Pros and cons section.

Diet and nutrition experts in the United States and abroad have warned the mono diet’s followers that they are likely to experience fatigue, a decreased metabolism, malnourishment, and muscle loss.

I don’t do diets.

I am trying the FDH diet.

When my daughter had mono, she lost her appetite for solids, like chewing was too tiring for her.
