'going to' and 'will' combined

[Eugene2114]

"I think a lot of people see food in terms of whether it's going to make them fat or make them skinny," he told yesterday's Wall Street Journal. "I'm seeing food in terms of how it's going to make me think and will it give me clarity."
- I wonder if there's nothing amiss using two constructions ('going to' and 'will') successively in a sentence.
Thanks.

The second sentence does not look great written down (it's presumably a direct quote, and in conversation people often do not speak in perfectly formed sentences). This is not because of the combination of "going to" and "will" per se but because of the embedded direct question "will it give me clarity", which does not flow properly with the rest of the sentence. It would be better to say "I'm seeing food in terms of how it's going to make me think and whether it will give me clarity."

Hi Dozy,
I guessed the speaker were bending the rules (he's not the only one, as I spotted before), but still: Is it considered frivolous to use the two constructions together or it would be better sticking to one (provided a sentence doesn't sound raw), eg 'going to' or 'will'?

Each sentence would need to be considered on its own merits, but there's no blanket prohibition. For example, your original quote is OK after the adjustment, and this is another random example which is perfectly OK:

"I'm going to talk to John, and then I'll make a decision."

Got it..
