Completely ridiculous conclusions based the information provided. Even if the standard diet were quantity restricted, it does not indicated the amounts actually ingested by each fly group. Timing as the sole controlled factor for an actual scientific experiment, requires that each group ingests the same amount. As such, the amount should be no more than that which can be ingested in a 12 hour period. To relate the finding to circadian rhythm, the timing should be varied based on normal sleep patterns.
