The Zone Diet at home is no longer difficult. The hard part of following Zone meal guidelines is when you must eat out for business or social reasons.
To eat the Zone Diet at home, you have two choices: do it yourself or get Zone Diet meals delivered to you.
If you do it yourself, it may help to be comfortable at cooking. I assume that because I'm a guy who has looked after himself since he became an adult, except for six years of marriage, and yet I have never gotten good or comfortable at cooking. I do some, but I keep it so simple it hardly qualifies as cooking. Many years ago I experimented with making cornbread and a few other hippie-like stuff, but that was long ago. Now I accept that the kitchen is not my strong point. When I'm not cooking something simple, I eat out. Simple and easy.
So when it came to cooking Zone diet meals, I have to admit I've never done more than skim the many Zone recipes Dr. Barry Sears has included in many of his Zone books (which are excellent). I'd get ideas from the simple ones.
But too many of them were created with the intention of helping people stay on the Zone diet by creating delicious meals that follow the 40/30/30 guidelines (40% carbohydrates, 30% protein and 30% fat) that Dr. Sears advocates.
Delicious meals that required fancy cooking is not what I was looking for. Maybe Barry Sears should come out with a Zone book for single people who hate to cook or who don't have time to. We're a neglected part of the entire cookbook market. Maybe he figures that we just read the section on how to eat in the Zone while dining out, especially at fast food restaurants and -- in my case -- he'd be right.
I know how to eat quarter pounders by removing one half of the bun. I also order three Gordita Supremes at Taco Bell, then place the insides of all three into just one shell.
Not 100% optimum Zone Diet health, but it's better than eating the full bun or lots of other carbs. And many of us can't afford to stay at home when we have to be out running around for work.
When I worked at Domino's, I used to eat pizzas by just skimming off the sauce, cheese and toppings, and throwing the crust away.
So I still ate lots of saturated fat -- I'm not claiming this was the healthiest way to eat -- but it was better than starving or eating the saturated fat along with the empty carbohydrate-full crust. Also, if you must eat pizza, you can reduce the intake of carbohydrates by ordering a thin crust pizza. Again, not a perfect diet, but the more you reduce your intake of extra carbohydrates, the lower you keep your insulin, and the healthier (or less unhealthy) you are.

But when you eat at home, you can control things better. You can plan some meals that appeal to you, referring to the Zone block tables in the back of the Zone books. Then you can go shopping at a supermarket or, better yet, a farmer's market or Whole Foods or Trader's Joe (but don't kid yourself - too many carbs are too many carbs, even when they're sold through "healthy alternative" outlets.)
You can now also eat the Zone Diet at home by getting meals delivered right to your door. Some services in major North American cities have their own delivery systems. The rest of us can get them by FedEx.
