It should be pretty simple guys.
Find your BMR out - its what your body requires to live based on your weight and no activity all day.
Knock off 200-300 from your BMR - by doing this your already in a calorie deficit
Go gym and burn more calories - even more in a calorie deficit
So for example if your BMR is 2300 a day, knock off 300 from that.
Burn another 300 from Gym or Cardio a day.
Your calorie daily intake is 1700, thus giving you a deficit of 600.
Do this daily and your cutting out 4200 cals a week.
1 pound of fat = 3,500 cals
I find it good to make a list of what I like to eat and put them in a spreadsheet, with the cals and macros. Takes a few mins from each day to update. Saves me having to guess what I am eating and my macros for the day.
I keep adding to this spreadsheet, I basically choose food from my list. I pretty much know what I am going to be eating for that day when I wake up. I like the "game" of finding low cal nice food lol low cal crisps yum
UK heads the ready made meals from MuscleFood are really good, high protein for a ready meal. Bland as hell though lol -

I try to keep my carbs low, protein high between 150 - 200g a day, carbs about 100-120
With MyFitnessPal its easy to track things in packages, scan bar code and thats it.
Anything else go online to get the cals and macros -
