High fat low carb = Insulin Resistant??

Commented on January 14, 2014
Created January 12, 2014 at 9:22 PM

I was told that low carb and high fat diet will result in insulin resistance. I've been following a low carb diet for a while and have been feeling well and losing weight. I would usually throw in a day of eating lots of carbs for leptin, hormones, ghrelin... I stopped with the 1 day carb up because I would feel EXTREMELY Horrible the next day. Lots of water retention, especially in my eyes. Carbs from white rice and sweet potatoes! What's going on? I'd really appreciate your help and suggestions as to what to do. Thanks in advance !!!

Have been on low carb high fat for a couple of months. I tried carb-ing up with sweet potato one day and end up feeling awful the next couple of days too. Is this normal? My BMI is 19 - I am not overweight...

BTW, to anyone reading, who is doing a low or vlc carb diet, those links are VERY worth reading. VERY.

You mean moderate carb all the time, instead of the high carb excesses of the SAD diet or vlc? Well moderate carb is what I do. A bit of fruit each day, the odd tuber or four each week, a bit of nuts as the odd snack, etc etc. I think myself that makes more sense than low or high carb, balanced as you say. If I worked out more, i might add a few more tubers. So long as its not an unbalanced diet of 50-70% carb calories, then your doing your insulin resistance a favour. But this isn't an answer to the question, which actually related to the way fats make our bodies adapt with low carb.

Yes. You eat less carbs, so you body saves what it has for the brain. It does this by creating insulin resistance, purely in the muscles (not the cells, adipose, organs, or brain). So your muscles power on fat. The consequence is that if you load on carbs, your will have a sugar spike. I was very low carb for a little while, and I experience a stimulant like explosion, dizziness, and a crash from some sugar I had to drink for a medical test. Its natural and adaptive, not pathological. But you need to be aware of it. IMO, its better not to go too low carb, just in case u end up loading.

If you really want to understand what's going on inside your body when you do this read a book called GRAIN BRAIN by Dr. David Perlmutter, MD. Your 1day carb binge is horrible for your entire body!

Let's think this through. We have 3 macronutrients: carbs, fats, and protein. Of these, only one will not signal insulin. If our cells are insulin resistant, they are so because of a chronic signalling of insulin.

Which macro doesn't signal insulin? Fat.

What would cause a chronic signaling of insulin? A constant source of macronutrient that signals insulin. The SAD is not full of people eating lean protein every 2 hours, it's full of people snacking and eating meals with high carbs. So perhaps eating a diet that's high in carbs around the clock, especially the terrible idea of eating 8 small meals a day isn't so hot.

Now, all carbs aren't the same, and all proteins aren't the same, and all fats aren't the same. Sure, if you eat hydrogenized oils/manufactured trans fats, or a diet in oxidized PUFAs, your health will go south and you may damage your pancreas and find issues with insulin resistance. But, if you eat mostly saturated fats, MUFAs and a good source of non-oxidized omega 3's, you will find your health will increase.

Be careful of the word balanced - it's a weasel word meant to disarm arguments. It has no validity when it comes to health. Yes, it's beneficial to do a carb refeed once a week, right after your glycogen depleting workout, but even then, you shouldn't do so using junk food such as cheetos. And yes, eating far more protein than you need can be toxic. You could use the word balanced in that sense, but don't use it as an excuse to introduce abominations like cheat meals comprised of wheat pasta, or GMO corn.

Not everyone on low carb will develop insulin resistance, and even in those who do, it's somewhat irrelevant... if dietary carbohydrate intake is low, then high sensitivity to insulin isn't really necessary.

Likely "physiological insulin resistance," see here and here.

I'm trying to introduce carbs little by little, but the small amount that I introduce just kills me the following day

that's what I've been trying to do. So I lowered my fat intake, uped my carbs, and the next day, I wake up feeling like I have a hangover, tired, and just horrible

Instead of doing low carb high fat 6 days a week and 1 day of high carbs (and presumably lower fat) 1 day a week, how about trying a balanced diet 7 days a week? Absurd right?
