I am not able ot reduce my weight, it is 73 kg

Hi,

I would like to say that the tips are very helpful but i dont know how to adjust my diet.

I am a vegetarian.

I wake up at 7 am and drink 3 glass of warm water, one glass with half tablespoon honey and little bit lemon, another glass of warm water with some fenugreek seeds and third plain glass of warm water, then have to do household work till 9 am then i have my breakfast (cornflakes / pauwa / upma with a glass of milk) then i leave for the office by 9:30, I reached office around 10 am then my job is of sitting and doing the work, i take lunch (one bowl of salad, 2 roti, one sabji), i sit for around 8 hours and then i leave my office by 06:30 pm and i go to gym at 7 pm then i start some warm up exercise for 15 min and then walking for 20 to 25 min and cycling for 10 to 15 min and then sit ups & other exercise for 10 mins. 5 days a week I reach home by 08:45 pm and then after 10 to 15 minutes i take my dinner, sometimes i eat panipuri, handwa, thepla etc and sometimes milk and cornflakes..
