Citation needed. I have known people follow a similar diet and lifestyle and develop depression.

"Exercise and get enough sleep" sounds like it could be convenient for moronic victim-blaming since depression, the disease itself, interferes with your ability to do those things. Imagine I had a broken leg "cure" that invilved running for ten miles a day. I could maintain my belief in that "cure" quite easily by just dismissing those unable to do that because, well, their leg is broken.

"I have known people follow a similar diet and lifestyle and develop depression"

It's not a similar diet and lifestyle then.

Maybe interferes with them, yes, but not flat-out prevents them from doing it like your absurd broken leg analogy. The point is, exercise and sleep are part of a whole. It's the many factors I mentioned that will lift depression. There are also other small changes in diet that help. If anyone doesn't believe this, they can easily take my suggestions to use for themselves. They have nothing to lose whatsoever.

This phrase, all by itself proves you know nothing about depression, nothing is easy when you are depressed, getting out of bed is an achievement, getting dressed too is often just too much.

But this -

They have nothing to lose whatsoever.

puts the icing on the cake of evidence for your ignorance of mental health as you have clearly never heard of suicide, look it up in a dictionary, then come back and explain to me how people with depression have nothing to lose by taking your advice rather than that of a qualified professional.

Nice fear mongering there. If there at that stage of depression (suicide) then they can simply use a dietary and lifestyle protocol as an adjunct to therapy (along with counseling or whatever they feel necessary).
