Praise be to Allaah.
It is not permissible to
break the fast for the reason you mention, rather it is haraam, because it
is not included in the reasons for which one is allowed not to fast in
Ramadaan.
From Fataawa al-Lajnah al-Daa’imah, vol. 10, p. 240
It should be noted that fasting in Ramadaan is an obligation
upon every accountable Muslim, and no one is excused from fasting at the
time of fasting except for those who have valid excuses, who are granted the
concession of being allowed not to fast, such as the sick, travelers,
pregnant and breastfeeding women, the very old and those who are forced to
break their fast.
