Advice

I currently weight 115kg (around 250 pounds) and I don’t know how to lose weight. I go to the gym three or four times a week and I try to eat healthily and I have tried and failed numerous times at calorie deficits but I don’t notice any difference. My target weight is 75-80kg (around 175-180 pounds). Does anyone have a good workout and exercise split and a diet plan for quick weightloss and fat loss. I’d like to avoid fasting and in a diet plan no fish. Many thanks
