Reducing such foods is benefical

لَيْسَ الْحِمْيَةَ أَنْ تَدَعَ الشَّيْ‌ءَ أَصْلًا لَا تَأْكُلَهُ وَ لَكِنَّ الْحِمْيَةَ أَنْ تَأْكُلَ مِنَ الشَّيْ‌ءِ وَ تُخَفِّفَ.

Abu Al-Hassan Musa (asws) has said: ‘Dieting is not leaving something which you originally did not eat, but the dieting is to eat from the thing but at a reduced level’.
