If the way you're eating now isn't making you lose weight, despite being in ketosis, then you obviously have to change the way you're eating. Regardless of what the latest Paleo-guru author says, everyone has their metabolic quirks. In the middle of 2010 after steadily dropping 6-8 lbs. a month with virtually no effort, I was less than 30 lbs. from my goal weight when I hit a plateau. Didn't lose a single pound FOR 4 MONTHS. After much frustration & experimentation with new workout programs, inc. running (which did nothing but make my knees ache -- after shrinking my wallet by $160 for the damn shoes!), bench presses & clean-&-jerks (got up to 50 lbs. & got big, broad shoudlers for my troubles -- which I thought couldn't happen to women!), & kettlebell training (which did change my body for the better! but at this point, I think I need some sessions with a real trainer), I decided to eliminate artificial sweeteners from my diet. I know there are people online who swear that Splenda/Nutrasweet is pure poison, a neurotoxin that causes sexual dysfunction, cancer, MS, Lupus, Alzheimer's & every other freakin' thing. Look, I'd been using Nutrasweet/Splenda since the 1980s -- if the stuff really is poisonous, I'd be dead a dozen times by now. However, I had read, in more than once place, that Splenda/Neutrasweet can inhibit weight loss. So I figured eliminating it was worth a try.
I switched to Agave syrup for a couple of weeks, then I discovered Coconut Blossom Sugar (which is costlier & harder to find, but totally worth it health-wise). Coconut Blossom Sugar is a natural product, still hand-made (apparently, the stuff doesn't lend itself to large-scale manufacturing processes) with the lowest Gylcemic Index (GI) & Glycemix Load (GL) of any sweetener I've found to date. I try to keep my BS below 100 (80-90) before meals & below 125 within an hour after a meal. So I became my own lab rat. I had a BS monitor (which is unfortunately now broken) so I checked by BS after having a cup of hot green tea with coconut sugar, which bought by fasting BS up to 112. (Tea with Agave syrup bought it up to 135.) When I drank the coconut sugar & tea with a normal breakfast (eggs & bacon), my BS peaked at 120. Ninety minutes post-prandial, it was back below 100. And 12 days after switching to coconut blosson sugar, I'd lost a couple of pounds -- & continued losing consistently. So switching to Coconut Blossom Sugar was the answer for me.
My suggestions for you:
1. START MONITORING YOUR BLOOD SUGAR BEFORE & AFTER MEALS
I'm not diabetic but my Da developed Type-2 diabetes in his 6o's, which makes me predisposed to it, so I started monitoring my own BS over the last couple of years. He's deceased now (not from anything related to diabetes), but what I've learned over the last 10 years of reading & self-experimentation has me convinced that he could have reversed his diabetes if he'd changed his diet. I believe MOST Type-2 diabetics can cure themselves if they're willing to ignore most of the conventional wisdom & switch to a VLC/Paleo-type regimen. I say all that to tell you that you need to start monitoring your BS too, Brad. BS meters are cheap as chips now (my doctor actually gives them away) but I think you still need an Rx for the lancets & strips. I've been following this guy's blog (Dr. William Davis) for about a year now & his info on BS & its importance in relation to weight loss & overall health had been very insightful. (BEST TIP: Even a single serving of 'bad foods' -- inc. oatmeal, which most folks consider a 'good carb' -- does real damage to your body in terms of glycation. Which makes it much easier to skip that slice of pizza or 'just 1 cookie'.)
BS values mean differet things for different people, depending on your age, body type, family history & a host of other factors that Dr. Davis talks about in his blogs. But generally speaking, if you can keep your fasting BS <100 before meals, with an increae of not more than 25mg/dl immediately after eating & a return to <100 within 1 hour post-prandial, you'll be safeguarding your health & losing weight at the same time
2. CUT OUT THE CARBS COMPLETELY (inc. all sweetners) FOR 7-10 DAYS
Seriously -- your body doesn't need carbs to function, so get rid of them for a week. No sweetners whatsoever -- if you drink a lot of tea (& I do), get used to drinking it unsweetened (green tea isn't bad unsweeetened) -- or switch to plain water with meals. Zero fruit, zero dairy (except butter or cheeses & make sure those are from grassfed cow's milk). No tomatoes, no carrots, no sweet potatoes or root veggies. If you simply 'have to' have veggies on a daily basis, stick to the Very Low Carb varieties: any & all types of lettuce, all the leafy green stuff (kale, collard greens), all the cruciferous veggies (cabbage, broccoli (yuk!), brussel sprouts.) INuts are OK but only Macadamias or Pecans becasue they're VLC (<1gm carbs per 2 tbsp. serving). Cut out carbs, continue with your usual workout regimen & see if you've dropped any weight after Day 7. (If not, keep at it for another 3 days.) If you've lost at least 2 lbs. at Day 10, then it's a good bet that artificial sweetner was inhibiting your weight loss.
3. IF YOU DON'T ALREADY, MAKE SURE ALL YOUR BEEF IS GRASSFED, DITTO FOR YOUR BUTTER & CHEESES
For me, the hardest thing about going Paleo has been the cost! With the recent spike in gas prices, I've had to stop buying organic veggies over the past few weeks & return to using conventionalaised produce in order to continue buying grassfed beef. Gassfed beef, butter & cheeses contain Conjugated Linoleic Acid. CLA has been shown to increase fat metabolism. (But it only works when the CLA is consumed in it's naturally-occurring form - i.e. in foods.) Luckily, my local Whole Foods always has grassfed beef on hand. I don't get the variety I'd like in terms of the cuts they have available. But I can always find grassfed ground beef & Kerrygold butter there. (The Kerrygold label doesn't say 'grassfed', but their website states that their cows are grassfed.)
4. IF ALL ELSE FAILS, CONSIDER CHANGING YOUR WORKOUT
If you know for sure that your eating habits aren't the problem, try a new fitness regimen. Kettlebells are my workout-of-choice. I haven't tried CrossFit Training yet, but what I've read about it makes sense. And from the videos, it looks like fun!
