Well, this is pretty obv but don't buy any non-Paleo foods. Nothing "unsafe" in the house. If it's not there, you can't eat it. I don't know what your living situation is, but the only food that comes into my house is food that I purchase, so I have it easier than some.

As for eating out in restaurants and other people's houses, if you're determined to do 100% Paleo, it might be tough - there are so many unknowns when someone else is making the food. Either tone down the social life for the next while, or ask a bazillion questions when you go out to eat and scan the menu online ahead of time to make sure there are safe items.

Personally I think saying "100 days of 100% Paleo" might be setting yourself up for failure. It sounds almost punitive, like a jail sentence. Especially if you are going from a history of struggling with food and willpower and making bad food decisions, to expect perfection from the get-go might be too overwhelming, stressful. And you slip up once and you're like, I suck at this, may as well quit.

Maybe I'm wrong, maybe it's good to aim high. But when I decided to try Paleo, my frame of mind was, let's see how this suits me, but I never thought of a time frame - it was more like, one day at a time, with the thought that if I like how this works, I will eat like this for the rest of my life.

Best of luck!

1. Don't buy foods not on your diet.
2. ???
3. Profit.

Not to be a smart ass, but sometimes it comes down to: Just. Don't. Eat. It.

Don't make excuses (willpower is often an excuse). Don't buy the food. Don't go to restaurants with the food. Don't hang out with people who eat the bad food. Once you get used to your new lifestyle you can relax the constraints because you won't be tempted any more.

I find that it helps to think of food as fuel, & to remember that for your body, you want only the best kinds of fuel. The non-paleo garbage that can be tempting is just that - garbage.

Also, I saw this quote recently & it's helped me remain more strict & resist non-paleo treats: "Don't reward yourself with food - you're not a DOG."

Be prepared. If you know you are going to be in a situation where paleo foods are not available, eat ahead of time, pack a snack or if you can handle it, just wait and eat later. I used to always keep a snack in my purse just in case, but now I usually just skip a meal if I have to, and eat later.

1: chill the F out. 2: eat delicious food 3: don't eat food that makes you feel like crap.

Diet compliance is a measure of willpower until it becomes a simple habit. Try to eliminate other stresses in your life while you work on your 100% paleo gig. Remember that after 30 days it will be a habit. You only need to put the effort in now to reap the benefits later.

I just imagine what I'm going to feel like the next day (as personally, eating grains/dairy has a very reliably negative effect on how I feel AND the way I look) and how its going to hold me back, and I'm good. And don't let yourself get too hungry if you're still struggling with adapting and think you might be in a difficult situation- have tons of protein or a super-fatty coconut thing.

I find it helpful to curse like a sailor (silently!) at the forbidden food. "F-U, pizza! I'm stronger than you are! F-off! I am not your [witch]!" You get the idea. I learned it from someone who did that to cigarettes to quit smoking. It worked with the luscious chocolate cake someone brought to work last week. I didn't eat it.

I don't think most people actually have good "will power" at all. Will power will not stop you from eating bad stuff if you get hungry enough and that food is what's available. So the advice some give to not have bad foods around, and conversely, make sure you DO have good foods around seems solid.

Since you've already articulated that you have "no will power," anyone who dispenses glib "just don't eat it" advice is pretty much ignoring your real question and not giving you a useful tool.

1) I would ditch the "100 days/100%" plan--you surely cannot achieve it. None of us can control our lives that completely, so why pretend? I started out with 2 solid weeks--that's just 14 days. Plenty of time to start seeing results, not so long that I couldn't see the light at the end of the tunnel. After I survived 2 weeks, I re-upped for another 2 weeks.

Honestly, after two weeks, my sugar/carb addiction had actually been broken, and that make week three SO much easier. In fact, after week three, the whole thing started to feel pretty effortless. I stopped counting days/weeks/months at that point because it didn't seem to matter. It started feeling feasibly sustainable--indefinitely.

Perfection is impossible for us mere mortals--only gods can achieve it. And for a person with no will power, it becomes the perfect excuse to say "f*** it," and ditch the whole plan when you eat a sandwich one day because you're stranded somewhere by events beyond your control, with nothing healthy in sight. 100 days is such a long time that the odds of a mishap or mayhem are huge. The odds of getting through 14 days unscathed are drastically better. Set yourself up for the best chance of success, and then grab it!

Here are some tricks that worked well for me:

2) Get addicted to a paleo podcast that's been on for a long time, but that you've never listened to before, and start listening to it incessantly. I considered it an immersion, SAD de-programming tool.

Early on I found "Latest in Paleo," and there were lots of episodes available. So I could literally listen to three or four episodes a day every day for the first couple weeks of the diet.

Not kidding: having Angelo Coppola's voice talking to me for several hours a day about all this paleo stuff really helped keep me motivated, and also helped keep my mind from wandering to bad foods. I'd listen on my walks from home to the train, on the train to work, the reverse commute, and especially when shopping for food!

Pretty soon I had listened to every hour that was ever broadcasted, but by then, I'd gotten links and tips to other podcasts, and blogs, and resources that I could then turn my attention to.

I found more podcasts, and turned to them whenever I needed to fill the silence with paleo instead of pasta:

1. Latest in Paleo podcast (Angelo Coppola)

2. Healthy Skeptic/Revolution Health Radio podcast (Chris Kresser)

3. Balanced Bites podcast (Diane Sanfilippo/Liz Wolfe)

3) I took on special food preparation projects--things I'd never made before. I bought a food dehydrator and learned how to make homemade beef jerky. I learned to make sauerkraut from scratch--and it was the best I'd ever tasted. Healthy, novel food projects are great ways to stay motivated and feel in control.

4) Then, I just started to revel in the luxuriousness of some of the foods that I'd forbidden myself before. I perfected making hollandaise sauce and poured lavish quantities of it on everything from eggs, to veggies, to salmon, to steak! I ate tons of fatty steaks in the beginning because they previously had been a kind of forbidden treat. Coconut milk--all that fat!--was now a staple food.

I have to admit that I've toned it down a bit lately, but in the beginning, it was great to just wallow in all that velvety luxurious fat!

5) Finally, I completely ignored exercise. I gave myself a free pass to just eat healthy and see what happened, and didn't stress myself out trying to worry about exercise. I didn't want to do anything that would spike my hunger for empty carbs/sugar anyway, so I just took a month off and did nothing special beyond my walks to the train. I started losing weight without lifting a finger. That was extremely motivating.

The one physical thing I did was switch to a standing desk at work, so that at my previously sedentary job, I was now burning extra calories just working at my computer. That took a month to adjust to, and I still have days when I get sore or stiff, but on the other hand, I go home from work feeling physically drained and tired. And THAT makes it a lot easier to eat dinner, and go to bed earlier--before I stay up late snacking on nasty food!

That's my way-too-long list of tips. Some of it may be completely inappropriate for you, but it's what worked for me. Good luck!

1) Drive to grocery store (or Walmart. It'll do.)

2) Park car

3) Walk inside to, I dunno, the frozen food aisles

4) Stare at brightly colored packages

5) Feel grip of monkey on back

6) Decide I'm "not ready" for... whatever it is I'm afraid of

7) Buy said packages, go home and consume

8) Feel relief (for 10 minutes)

9) Feel like s**t (for hours, days, however long it goes this time)

10) Have actual experience of what being "not ready" feels like

11) Get back on the wagon

12) Repeat until I'm ready
