Considering parallel structure, B is the answer.

i understood the answer but a general question :
why do we need "the" in (B) -  self-deprivation or  the  adoption of an extreme diet, but of 
would  self-deprivation or adoption of an extreme diet, but of  be correct as well?

In most cases, we'll want to keep "the" for this kind of situation. Read these and see what you think when I take out "the":

Does the second of any of those pairs seem off to you? They do to me. My first thought is that we are referring to one particular event, or one stage in a sequence of events, but I don't think that's the key. Really, we're using "the" the way we do before many kinds of nouns. After all, we'd say "the making of a new language," "the laying of eggs," "the end of the project," etc. Also, in the original case, if we don't have "the," we could read "self-deprivation or adoption" as the two parallel terms, with "of a new diet" modifying both, and that doesn't make sense. While we shouldn't read the sentence that way, adding "the" also makes it clearer that that isn't what the sentence is trying to do.

Why not e?
Since the option e contains that as a pronoun

ExpertsGlobal5 · Answer

Hello  BOB1993 ,

We hope this finds you well.

To answer your query, Option E fails to maintain parallelism between A ("of self-deprivation or adopting an extreme diet") and B ("that of a healthy lifestyle") in the idiomatic construction "not A but B"; remember, “not A but B” is a correct idiomatic usage; A and B must be parallel and comparable.

We hope this helps.
All the best!

(E) has multiple problems.

We have the correlative conjunction - not X but Y - where X and Y must be parallel.

Non underlined part is this: 
Recent research has indicated that sustainable weight loss is generally a result not of ... (but of) ... a healthy lifestyle that integrates a balanced diet, regular exercise, and a long-term approach.

"lifestyle" is a pure noun and for parallelism, it would be good to have a pure noun after "not of" also. 
"self-deprivation" and "adoption" are pure nouns which makes (B) more suitable.

Also, "but of" is parallel to "not of" and hence, we should avoid "but that of" as far as possible.

So (B) is better than (E) in both cases.
