Sure, I looked up my TDEE on google and found that I had to eat less than 3500 or so calories per day to lose weight. At first I decided I'd just stick to around 2000 per day, but after a few days I realized that I wasn't as hungry as I thought I would be so I just lowered it until I got to 1350. Keep in mind though that I didn't do any sort of cardio or exercise so that's why the number is super low.As for figuring out the calorie content, I measured everything (invest in a food scale, it helps a LOT) and just used the nutritional information on the packages, or I would just use google for stuff. I cooked everything myself, which made it a lot easier.
