Is it impossible to find any enjoyment in challenging your body as well as mind?
Don't try to generalize my argument into absurdity. Simply not doing math because it is difficult doesn't solve the underlying problem, which is probably to become proficient at math. Now if there were easier ways to become proficient at math than what you were already doing, that would be more in line with my argument.
The key thing is solving problems. Simply giving up on learning math, or reading, solves no problem.

Challenging your body and maintaining good health are distinct goals, though they may be satisfied through the same processes. If you want good health, and a certain diet makes that easier, then I will say that it is no sense in maintaining whatever old diet you had simply because that would make it harder. If you want to challenge your body, and simply maintaining good health is not challenging enough, there are endless possibilities. Recreational sports, for example. Gymnastics. Parkour. But personally I would not choose to do things that were clearly suboptimal for my body solely because it would be more challenging. I might do it because I gain other things, such as eating tasty but unhealthy food, but I wouldn't choose to do it if the goal was only to make things harder for myself.
Being challenging also doesn't imply an activity is unenjoyable or unrewarding.

What things?
You assert that exercising and changing your diet have the same end result when they clearly do not, unless you are using "healthy" as a euphemism for "lose weight" or something similar. Do you have a factual basis for asserting that changing your diet and exercising result in the same end results?
Thank you for clarifying that you do not find exercise enjoyable, I was curious if that was the case. I find exercise to be rewarding in it's own right - it's unfortunate that you don't experience it the same way.
"No pain, no gain" can be interpreted as saying that sometimes it is worth enduring discomfort or pain in the short term for a longer term reward. It's more a comment on dealing with delayed gratification than a description of whether an activity is enjoyable or worth doing.
