I eat a lot of bars and stuff. Kind of like the 5-1, 3-2-1, etc type plans. I keep a bunch in my bag. Each ranging from 70 cals to 190. I eat the bigger ones twice during the day and a couple of small ones. Keeps me in the ~700 cal range. Then for dinner I cook something with red meat because I crave it pretty hard.
Leaves me with an end total at about 1200-1300 cals at the days end.
Some don't agree with the method. I sub in oatmeal in the morning sometimes (like 140-180 cals) and fish for lunch (90 cals) but it is so convenient I can't really slip up. I always have a bar right there to curb cravings/bad thoughts.
It's taken about 2 months but I've dropped 14 lbs. Slow and steady
