40 participants in 3 patient groups, including a placebo group

Normal Diet

Placebo Comparator group

Description:

Participants in the normal diet (ND) group will follow a traditional dietary pattern, consisting of eating breakfast and continuing to eat throughout the day until the evening. Participants in this group will receive placebo capsules. Participants in all groups will follow an identical resistance training program and be provided with whey protein supplements.

Treatment:

Dietary Supplement: Protein Supplementation

Other: Resistance Training

Time-Restricted Feeding

Experimental group

Description:

Participants in the time-restricted feeding (TRF) group will consume all calories within an 8-hour period of time each day. Participants in this group will receive placebo capsules. Participants in all groups will follow an identical resistance training program and be provided with whey protein supplements.

Treatment:

Behavioral: Time-Restricted Feeding

Dietary Supplement: Protein Supplementation

Other: Resistance Training

Time-Restricted Feeding plus HMB

Participants in all groups will follow an identical resistance training program and be provided with whey protein supplements.

Treatment:

Behavioral: Time-Restricted Feeding

Dietary Supplement: Protein Supplementation

Other: Resistance Training

Dietary Supplement: Beta-hydroxy beta-methylbutyrate
