weight loss diet for fight opinions

looking to lose weight for a fight

im 20 and i train between 2.5-4 hours a day, resting on sundays so im extremely active
im 73kg and 5’10

most of my weight is in muscle im quite toned
is this a good diet with a goal of reaching 65-68kg standing weight within the next 12 weeks?

7am porridge with honey

1:30pm apple banana orange a bunch of grapes and some mixed nuts

7pm 1 chicken fillet chopped with rice, mixed vegetables and some spices

about 3.5 liters water a day

i know variety is important but i don’t have time to be coming up with new dishes while im training and i have a very mixed random, healthy enough diet through the rest of the year
