Halocho #244 - Fasting on Shabbat is forbidden

One should not abstain from food on Shabbat in order to fast - even for a few hours.

Even without any intention of fasting, one shoud try eating before midday.

Halocho # 194 - Until when can one daven Mussaf?

Mussaf is added after the Torah Reading of Shacharit (morning prayers) on Shabbat, Yom Tov and Rosh Chodesh.

• Shacharit corresponds to the daily morning sacrifice offered in the Bet Hamikdash.
• Mussaf corresponds to the extra sacrifices offered on Shabbat, Yom Tov and Rosh Chodesh.
• Mincha corresponds to the afternoon daily sacrifice.

While Mussaf can be said until sunset, it preferably should be said before the "7th hour"; an hour after midday. If Mincha-time has already arrived (half hour after midday) and one has not yet said Mussaf then one should first pray Mincha then Mussaf. This applies when praying in private; a community should follow the regular order; Shacharit, Mussaf and then Mincha.
