Can be a Long complex topic....
Simply put to start, dont start eating less right away add in 3-4 cardio sessions a week, when weight plateaus reduce cals by ONLY 200-300 cals at a time for weight loss, increase cardio up to 6 times a week max imo, only reduce cals when needed in small increments to keep metabolism going, its FAR better to diet and loose weight on as MUCH food/calories/carbs as possible whilst including cardio sessions, cardio boosts metabolism and more calories boosts metabolism, naturally when dieting and loosing weight this slows down so you want to keep it going as fast as poss, eat as many small meals a day as poss with your allowed calories, consume protein every 2.5-3.5hrs
In the gym lift as heavy as you can ALL the time no matter what anyone says about higher reps when cutting, shorten rest periods as said a little but not to much, dont overtrain with to many supersets and negative sets etc.
When weight loss slows or halts then a variable will nedd to be changed, increase/change cardio/time of cardio/intensity, reduce or INCREASE cals, calorie cycle and carb cycle, your body wants to stay the same so it makes weight loss harder and harder the leaner you become so you will have to keep tweaking to get to the lower levels of bodyfat.
Just my 2 cents.
