keep in mind that no diet can be delicious, fun and successful at the same time ( unless you count calories ).

food must be restricted in some way.  it can be calorie counting, it can be fasting, or it can be by keeping food bland ( no cheese or sauce ! )

you need to be clear on what is the mechanism that will ultimately reduce your food intake.  you must pick one of the three i listed above.

all the yapping about carbs and fats is diversion - it's all just to eliminate fun foods ( which usually contain both ).

if you are avoiding a macro but trying to keep food fun you're chasing your own tail and defeating the very purpose of what your diet was really supposed to accomplish.

nobody will tell you this except me, but it's the truth. 

 In my peak diet era to lose weight for example I'd have 6 hard boiled eggs and some bread with butter for a meal. 

 well that sounds bland i will give you that

but i'm not sure it qualifies as a great diet

eggs already have more or less the right protein to calories ratio so adding bread and butter to them would just slow weight loss

i would just have 6 eggs and call it a meal

and i would certainly have them soft boiled than hard boiled

there is a difference between not adding sauce to a meal and deliberately ruining it to the point of being almost inedible

😄  

 Oh I wouldn't claim it was a great diet at all, but it worked.  Also this was several years ago and I would do things differently now in the same situation.  The bread is of course not essential but it made the meal seem more complete.  I kept my diet bland for a couple of years until I was in the range I wanted to be, and there were many variations.  For example, I would also use chicken and steamed vegetables for dinner.  Or for breakfast, I would have granola, whey protein and yogurt with some jam -- it was certainly the case that fiber acted as an appetite suppressant.  

Not a great diet but it wasn't meant to be, it was just a means to an end. 

 yeah to be honest i would rather fast or count calories than eat bland food

but everyone has to find what works for them
