High over ZZZZZ [fix]. It was the last leg of a three-day. No HGS (Head-up Guidance System) and had to fly like I did as an FO without HUD (Heads-up Display). Just fell a little behind; probably from being tired; not eating much since airport selections are minimal; and not having flown an approach without a HUD in over a year.[Suggestion] Take meals with me because of the COVID impact on airport food. Fly without the HUD periodically. I did great on that approach and was stabilized at 1;000 feet in the end.
Air carrier Captain reported an altitude deviation during approach.
