A systematic search for studies on these claims found zero—no data on the 60-70% figure, no data on modifiable risks, no data on warning signs. We're citing numbers with no research behind them. https://s.fitbodyscience.com/DwykSk

The breakdown

No research found to back up these dementia claims — but that doesn't mean they're wrong.

We searched for research on each of these specific claims and came up empty — no studies either supporting or contradicting them. That doesn't mean the claims are false, just that we have no evidence to evaluate them. So we can't say whether the 60–70% figure is accurate, whether those warning signs are reliable, or whether those lifestyle changes actually reduce dementia risk. It's a bit like being handed a list of facts with no sources — they might be true, but we can't verify them from what we have.

Bottom line

We found no research to confirm or deny any of these claims, so take them as unverified — but they're worth discussing with a doctor if you're concerned.
