Probably the hardest part of figuring out what the hell to do is wading through all of the bullsh*t scattered across the internet. From websites labeled "Healthy Eating" and "Bodybuilding" to general interest forums, it's a cacophony of noise that can end up hurting your goals more than helping them.
If you do want to do your own research on a subject, here's what to avoid and what to look for.
Advice with No Evidence
In terms of physical fitness, evidence, to me, means a picture of their body. Anyone can post anonymously about how they cut at 4,000 calories and weigh 135 with 0% body fat. Few would be able to point out that 4,000 would never drop anyone down to 135 and that 0% body fat is extremely unhealthy.
If you don't know whether to trust a response, check to see if they've ever posted progress photos of themselves. If they haven't, ignore them and move on. Right or wrong, it's safer to assume they're lying until they prove otherwise.
Advice from Bribery
Even if they post pictures, you still need to be wary. There are those out there that post really bad, really biased information due to marketing deals they've signed (we all gotta eat). They'll talk about specific supplements paired with a diet that only totals out to 1200 calories.
My rule of thumb is that if a pro suggests a product anywhere in their article/response, they are being paid to do so. Real masters (and this goes for every subject) know that there's no special product to get you what you want. Real masters give astounding advice through very generalized bits of information that can apply to anyone.
If you're looking for a specific answer, look in more than one place. Even if you feel you gained everything you needed from a simple comment by Schwarzenegger on Reddit, find answers on at least two other sites. It's not that Arnold's advice was bad. It's that it might be incomplete. By piecing together the whole picture, you save yourself from making potentially costly mistakes.
Go For the Source
If you feel really confused about something, pinpoint the origin of the proposed fact. Is it pulled from a study? Is their conclusion accurately summarized? Is it a quote some famous person said long ago? This will give you better standing when trying to figure out if the information is worth using or not.
A Note on Research
Never stop asking, "why?" Though this simple questions opens more rabbit holes than closes doors, it is your key to really learning how to sift through swathes of information. The more you know about a subject, the easier it will be to find what you're looking for.
