Narrative:

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 first officer 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.
