Austin claim dad lost a lot of weight by eating grapefruit before each meal. Austin seizure wants him to revise his claim. Why doesn’t Austin‘s claim need to be revised

Austin's claim doesn't need to be revised because he is simply stating that his dad lost a lot of weight by eating grapefruit before each meal. It is presented as a personal observation or anecdote, without any scientific or statistical evidence provided. Therefore, it is his subjective claim, and there is no need for revision as he is expressing his own experience or perception.
