My routine since starting this is
[ul][li]Water in the morning (or a sodium free mineral water for a flavor treat omw to work)[/li][li]Protein shake at lunch (organic non-whey non-soy protein,https://www.amazon.com/Orgain-Organic-Protein-Powder-Chocolate/dp/B00J074W94/ref=sr_1_1_a_it?ie=UTF8&qid=1472576176&sr=8-1&keywords=orgain%2Borganic%2Bprotein%2Bshake[/li][li]Sometimes I use coffee in my protein shake for that starbucks milkshake taste and caffine boost[/li][li]Light dinner of lean meat and vegitables (Salad or steamed vegitables + salmon or chicken.)[/li][li]In between those two main meals I try to get 2 snacks a day of either 100cals of raw almonds/walnuts and turkey jerky.[/li][/ul]To be honest, I love jerky, and turkey jerky is so low in calories and so delicious that I look forward to each snack. The entire bag of jerky lasts me about a week, and in total is like 300 calories.
Like null said, just trying to keep my calories low and my activity level normal or slightly above normal (light gym cardio and weight lifting a couple times a week.)
I can't stay under 1500, if I do I feel tired and really hungry. I was consuming over 3,500 calories for most of my adult life, but I also used to be much more athletic until about 3 years ago that stopped due to work hours and injury.
A side note, I am going to the doctor for a follow up on knee MRI's today, and hopefully get that figured out, so combined with my weight loss maybe I can go back to sitting on the ground to play video games soon - athleticism!!!
