So I never really keep a log of meals per se, but this is what I do (bear with me while I go through a little backstory).
Last time I prepped I wasn't originally going to do any contests so I started dieting kind of wacky for BBers. I told myself I was going to experiment and see what foods I could get away with and whether you had to eat traditional BB diets to get shredded or not. Keep in mind this wasn't IIFYM, but many assumed it was at the time--I was eating wheat of any kind (pasta, tortillas, bread, bagels on higher carb days, low-sugar cereal, and so on), dairy (2% or fat-free as I got deeper in the diet--stuff like cheese, light yogurt, and light / FF sour cream...burritos taste better with these two things), lots of protein shakes, etc. Found out that for ME it didn't make any difference (ended up doing two shows that year and winning my class of 14 at the first and taking 2nd in the other one (similar amount of competitors). So with that being said...this is what I did / continue to do and I'll continue to eat like this until I find I have issues with it.
Anyways, I start my diet by writing out my macros and giving myself a sample "diet" for each day with macros listed beside each food item. However...it's just a general guideline--if I don't feel like eating whatever I wrote on there, I simply switch it out for something similar i.e. 25g of carbs from rice can easily become a burger bun.
Then I just log my weekly calories / macros (and the different days and how they're structured when carb cycling) and adjust that weekly. The original list is just glanced at and altered to make it work for each week--if this gets too difficult because something has dropped too much, I just write out a new "sample" list and continue on.
I log the calories, macros, supplements, weight changes, cardio amounts, and FEELINGS for the week into a text file that I put into each week's folder with the pics taken, as well as adjustments I might have made that week and ones I intend to make for the next week and what reasons I'm making them. For example "lost 2.5lbs this week, felt like crap, added extra 100g carbs to high day, keeping calories same next week"
Hope this makes sense. Worked for me but may not for others. Keep in mind there was no "junk" eaten at any point even though I was just fitting the macros and calories.
Kind of rambled here, hope it's clear!
