One of the big keys to this way of eating is not being afraid of the fat intake, if you find yourself hungry between meals , it probably means your fat intake is too low (the other is the habit of snacking all day, but I will cover that in another post). I know we have been told forever to keep the fats low, especially the saturated fats and keep the carbs high, but that has led us to being one of the most unhealthy nations in the world. You can do a search and find a whole host of info on this subject by people who are much smarter and better writers than myself, so I will let you geek out on that on your own. Each meal should contain plant based fats such as Olives (Monounsaturated Fatty Acids), Avocado (MUFA) and Coconut (Saturated fat). My recommendation is to keep the consumption of Polyunsaturated fats such as nuts and seeds low as they are high in Omega 6, as we know we want to have a proper 3:6 Ratio. Here is a link to a good article I found http://paleozonenutrition.com/2011/05/10/omega-6-and-3-in-nuts-oils-meat-and-fish-tools-to-get-it-right/ , Also Mark Sisson http://www.marksdailyapple.com/ and Chris Kresser http://chriskresser.com/ have great stuff on this topic if you want to read more.
Another key is preparation, as we all know when we get hungry, we are going to go to the first thing we see, we don’t care if it’s good or bad. Have something prepared, and have it with you if you are not going to be home, it does you no good in the fridge at home if you are at work. Also cook your own meals unless you absolutely have to eat out. Even good foods out will be cooked in high Omega 6 oils and grill contamination is always prevalent.
I realize life happens, you can’t live in a shell your whole life, you need to go out and live, but for the first month it is important to get a good start and get good habits established so when something does come up, you do what you have to , and get right back on track. Good luck and don’t hesitate to ask questions.
