If the Insulin Theory of Obesity is correct then my question for Richard Morris, Jimmy Moore, and other obese Low Carb luminaries is:
@richard I am curious about your podcast intro. You say that all signs of disease are gone but I’ve also heard you state that your Fasting Insulin is high. That would suggest that at least one of the markers of Insulin Resistance is still present. Is that a concern for you and what are you doing to try and reverse that? Would further weight loss help? (I know you and Carl both say weight loss isn’t necessarily your goal). I know you ride your bike quite a bit so that sort of intervention seems only so helpful in your case.
Two of the signs of metabolic syndrome are waist circumference and fasting insulin levels. Richard and Jimmy have both stated they have high fasting insulin levels and they both have substantial waist circumferences.
My contention is that weight loss is necessary in order to lower fasting insulin. And yes, it is true that higher fasting insulin levels make it much harder to lose weight. Note I did not say impossible, just much harder. But they also make it much more important to lose weight.
Here’s evidence that fasting Insulin correlates to BMI. A great place for an answer to this question to look is very young people. There was an interesting study which looked at seven year old children (Hrafnkelsson H1, Magnusson KT, Sigurdsson EL, Johannsson E. Association of BMI and fasting insulin with cardiovascular disease risk factors in seven-year-old Icelandic children. Scand J Prim Health Care. 2009;27(3):186-91.). Here’s what they learned in these young children:
Some 14% of the participating children were classified as overweight. Overweight children had higher fasting insulin, higher fasting glucose, and higher systolic and diastolic blood pressure. Furthermore, they had significantly lower total cholesterol (TC), lower high-density lipoprotein (HDL), and lower low-density lipoprotein (LDL) but a similar TC/LDL ratio to normal-weight children. The factors that were strongly associated with BMI were serum fasting insulin, systolic blood pressure (SBP), HDL and fasting glucose, while the sum of four skinfolds, triglycerides, glucose, and LDL were highly associated with fasting insulin.
The LDL part is interesting (but not the subject of this thread).
BMI and fasting insulin are clearly correlated. Does one cause the other? Probably. Does it actually matter? If lazy ket0 isn’t working then look around. Protein Sparing Modified Fasts are a special case of keto with low fat and low carbs. But the high fat kings won’t try them (recent pictures of Left to Right Richard Morris, Carl Franklin, and Jimmy Moore). As far as I know none of these guys will post their food diaries. In fact, they seem to not track their food intake.
Again, this is not intended to ridicule any of these men. Rather, it is to question their dietary advice. They are all low protein and high fat advocates. And it worked for them. Until it didn’t work.
