	PD Model					Intervention
Author	Model	Toxic	Dose	Duration	Administration	Diet	Duration	Administration	Results
[19]	C57BL6 mice	MPTP	25 mg/kg	35 days	Intraperitoneal	Ketone diet (MCT-KD)	42 days	Oral	Protection against the loss of DA neurons and alterations in the gut microbiota and its metabolites.
[20]				7 days		High-BCAAs (H-BCAA)	56 days		Relief of both motor and non-motor symptoms, promoting SCFAs.
[21]		Rotenone	30 mg/kg	21 days/28 days	Gavage		360 days		Anti-inflammatory effect in the gut and brain
[22]		MPTP	20 mg/kg		Intraperitoneal	Fasting-mimicking diet (FMD)	Three 7-day cycles (FMD for 3 consecutive days in each cycle)		Recovery of motor function, mitigation of loss of dopaminergic neurons, and increase in DA and 5-HT levels.
