Sitting around the dinner table this evening we began discussing personality types. As a fun exercise, we each took the Jung Typology Test based on Jung and Myers-Briggs findings about personality. If you haven’t taken this personality test, you might find it quite interesting and the topic of hours of conversation around the dinner table . . . as we did this evening. The test is free on-line and takes about 10 minutes.

The actual Myers-Briggs Type Indicator costs about $50.00 and includes an interpretation by someone trained in giving the test. It differs slightly in its questions and the way the testing is interpreted.
Both tests provide an interesting insight into your individual psychological preferences regarding four categories. According to Carl G. Jung’s theory of psychological types published in 1971, people can be characterized, first, by their preference or general attitude about the source of and how they express their energy:
Extraverted (E) vs. Introverted (I)
The second preference is one of the two functions of perception, or related to how they perceive information coming from either the external or internal world:
Sensing (S) vs. Intuition (N)
and the third preference relates to how one processes the information that they have received, acting as one of the two functions of thought or judgement:
Thinking (T) vs. Feeling (F)
Isabel Briggs Myers, a researcher and practitioner of Jung’s theory, proposed that the fourth preference related to how one applies or implements the information that he or she processed above. She proposed a judging-perceiving relationship as the fourth dichotomy influencing personality type in 1980:
Judging (J) vs. Perceiving (P)
Each of these dichotomies represents an opposite pole of preference and each of us have a dominant pole toward which we gravitate.
Based upon your dominant traits, a personality type index is assigned.
Kim and Lee studied these personality preferences and how they relate to diet, health and propensity toward obesity. Their findings were interesting in that expression, perception and judgement did not seem to have any bearing on health or obesity. However, the application of judgement vs perception did play a role in health. Judging (J) means that a person organizes all of his or her life events and, as a rule, sticks to those plans. Perceiving (P) means that he or she is inclined to improvise and explore alternative options.
Significantly better dietary and health behaviors were identified in those preferring Judging (J) versus those preferring Perceiving (P) traits. Those preferring the Judging (J) behaviors included eating breakfast, regularly eating three meals a day, smoking less, exercising more and having a lower tendency to nocturnal eating.
The findings show that the use of Jung Type or Myers-Briggs Type Indicator may be helpful in identifying and index those with a Perceiving (P) trait that would benefit from dietary and exercise education, nutritional counseling and/or behavior modification programs.
It has been my experience that those with a “P” type dichotomy preference would benefit greatly from daily food planning and journaling.
So, what is your Jung/Myers-Briggs type?
Just for fun, and because my kids were very curious about what each personality type would appear as in character, I’ve included the Jung/Myers-Briggs Disney typing.
I’ve been looking for the answer for quite some time. . . what role does caffeine play in your and my weight management journey? The answer gave me a headache. . . literally and figuratively.
As many of you, including my office staff, know, I love my Diet Dr. Pepper (and my bacon). I found that being able to sip on a little soda throughout the day significantly helped the carbohydrate cravings and munchies during a busy and stressful day at the office. Diet Dr. Pepper contains caffeine, however, I wasn’t really worried. Caffeine has been well know to have a thermogenic effect which increases your metabolism and has been thought for many years to help with weight loss among the weight loss community.
Diet Dr. Pepper is, also, one of only four diet sodas on the grocery store shelves that doesn’t contain acesulfame potassium (click here to see why most artificial sweeteners cause weight gain). The four diet sodas that I have been comfortable with my patients using are Diet Dr. Pepper, Diet Coke, Diet Mug Root-beer and Diet A&W Cream Soda. These are the last four hold out diet sodas that still use NutraSweet (aspartame) as the sweetener. Most of the soda companies have switched the sweetener in their diet sodas to the insulinogenic acesulfame potassium because it tastes more natural and aspartame has been given a media black eye of late. However, NutraSweet (aspartame) is the only sweetener that doesn’t spike your insulin or raise blood sugar (click here to find out why that is important).
Yes, I know. The ingestion of 600 times the approved amount of aspartame causes blindness in lab rats (but we’re not lab rats, and . . . have you ever met someone that drinks 600 Diet Dr. Peppers in a day? The lethal dose of bananas, which are high in potassium that will stop your heart, is 400). Aspartame can also exacerbate headaches in some (about 5% of people) and I’ve had a few patients with amplified fibromyalgia symptoms when they use aspartame. But for most of us, its a useful sweetener that doesn’t spike your insulin response, halting or causing weight gain.
But, over the last few years, I’ve noticed that increased amounts of Diet Dr. Pepper & Diet Coke seem to cause plateauing of weight and decreasing the ability to shift into ketosis, especially mine. I’ve also noticed (in my personal n=1 experimentation) that my ability to fast after using caffeine regularly seems to be less tolerable, causing headaches and fatigue 8-10 hours into the fast, symptoms that don’t seem to let up until eating. Through the process of elimination, caffeine seems to be the culprit.
After mulling through the last 10 years of caffeine research, most of which were small studies, had mixed results, used coffee as the caffeine delivery system (coffee has over 50 trace minerals that has the potential to skew the results based on the brand) and never seemed to ask the right questions, the ink from a study in the August 2004 Diabetes Care Journal screamed for my attention.
It appears that caffeine actually stimulates a glucose and insulin response through a secondary mechanism. The insulin surge and glucose response is dramatically amplified in patients who are insulin resistant. Caffeine doesn’t effect glucose or insulin if taken while fasting; however, when taken with a meal, glucose responses are 21% higher than normal, and insulin responses are 48% higher in the insulin resistant patient. Caffeine seems to only effect the postprandial (2 hours after a meal) glucose and insulin levels. The literature shows mixed responses in patients when caffeine is in coffee or tea, probably due to the effect of other organic compounds (1).
Caffeine effect on plasma glucose and plasma insulin compared to placebo (1).
Caffeine also diminishes insulin sensitivity and impairs glucose tolerance in normal and already insulin resistant and/or obese patients. This is seen most prominently in patients with diabetes mellitus type II (stage IV insulin resistance). Caffeine causes alterations in glucose homeostasis by decreasing glucose uptake into skeletal muscle, thereby causing elevations in blood glucose concentration and causing an insulin release (2-6).
Studies show that caffeine causes a five fold increase in epinephrine and a smaller, but significant, norepinephrine release. The diminished insulin sensitivity and exaggerated insulin response appears to be mediated by a catacholamine (epinephrine, norepinephrine & dopamine) induced stress response (5). Caffeine has a half life of about 6 hours, that means the caffeine in your system could cause a catacholamine response for up to 72 hours depending upon the amount of caffeine you ingest (7).
The reason for my, and other patient’s, headaches and fatigue after a short fast was due to the exaggerated stress hormone response. Increased levels of insulin were induced by a catacholamine cascade after caffeine ingestion with a meal, dramatically more amplified in a person like me with insulin resistance. The caffeine with the last meal cause hypoglycemia 5-7 hours into the fasting, leading to headaches and fatigue that are only alleviated by eating.
Even when not fasting, the caffeine induced catacholamine cascade causes up to 48% more insulin release with a meal, halting weight loss and in some cases, causing weight gain.
Caffeine is not the “Wonder-Boy” we thought it was.
How much caffeine will cause these symptoms? 50 mg or more per day can have these effects.
10,000 mg (10 grams) – lethal dose (Yes, 25 cups of Starbucks Coffee can kill you)
The equivalent of 100 mg of in a human was given to a spider, you can see the very interesting effect on productivity. How often does the productivity of the day feel like the image below?

Beware that caffeine is now being added to a number of skin care products including wrinkle creams and makeup. Yes, caffeine is absorbed through the skin, so check the ingredients on your skin care products.
Diet Dr. Pepper, my caffeine delivery system of choice, has slightly less caffeine (39 mg per 12 oz can or 3.25 mg per oz) than regular Dr. Pepper. I found myself drinking 2-3 liters of Diet Dr. Pepper per day (long 16-18 hour work days in the office). After doing my research, I realized that my caffeine tolerance had built up to quite a significant level (230-350 grams per day).
So, a few weeks ago, I quit . . . cold turkey.
Did I mention the 15 withdrawal symptoms of caffeine? (8)
Headache – behind the eyes to the back of the head
Sleepiness – can’t keep your eyes open kind of sleepiness
Irritability – everyone around you thinks you’ve become a bear
Lethargy – feels like your wearing a 70 lb lead vest
Constipation – do I really need to explain this one?
Depression – you may actually feel like giving up on life
Muscle Pain, Stiffness, Cramping – feel like you were run over by a train
Lack of Concentration – don’t plan on studying, doing your taxes or performing brain surgery during this period
Flu Like Illness – sinus pressure and stuffiness that just won’t clear
Insomnia – you feel sleepy, but you can’t sleep
Nausea & Vomiting – You may loose your appetite
Anxiety – amplified panic attacks or feeling like the sky is falling
Brain Fog – can’t hold coherent thoughts or difficulty with common tasks
I experienced 13 of the 15 that lasted for 4 days. I do not recommend quitting cold turkey unless you have a week off and someone to hold your hand, cook your meals and dose your Tylenol or Motrin. My wife thought I was dying. . . I thought I was dying on day two. I actually had a nightmare about buying and getting into my own coffin. It can take up to three weeks to completely recover from caffeine withdrawal.
The other way to quit is to decrease your caffeine intake by 50 mg every two days. That means decrease caffeine by:
1 can of soda every two days
1/4 cup of coffee every day
1/2 can of Energy Drinks every two days
1 cup of tea every two days
The benefit of this method is that withdrawal symptoms are much less severe without the caffeine headache and the ability to remain productive. It will take longer, but quitting cold turkey is not a pretty picture. Been there . . . done that, . . . and I’m not going back. I actually lost another half inch off my waistline by day 5 of caffeine discontinuation.
What is the take home message here? If you have any degree of insulin resistance, caffeine makes it worse and will amplify your weight gain as well as decrease the productivity of your day.
Diseases seem to arrive in three’s each day in my office. Today I had three different patients with cholesterol concerns who were notably confused about what actually makes the cholesterol worse, and what causes weight gain. Each of them, like many patients that I see, were stuck in a state of confusion between low fat and low carbohydrate lifestyle change. My hope is to give my patients and anyone reading this blog a little more clarity regarding what cholesterol is, how it is influenced and how it affect our individual health.
First, the standard cholesterol profile does not give us a true picture of what is occurring at a cellular level. The standard cholesterol panel includes: total cholesterol (all the forms of cholesterol), HDL (the good stuff), LDL-C (the “bad” stuff) and triglycerides. It is important to recognize that the “-C” in these measurements stands for “a calculation” usually completed by the lab, and not an actual measurement. Total cholesterol, HDL-C and triglycerides are usually measured and LDL-C is calculated using the Friedewald equation [LDL = total cholesterol – HDL – (triglycerides/5)]. (No, there won’t be a quiz on this at the end . . . so relax.)
However, an ever increasing body evidence reveals that the concentration and size of the LDL particles correlates much more powerfully to the degree of atherosclerosis progression (arterial blockage) than the calculated LDL concentration or weight (1, 2, 3).
There are three sub-types of LDL that we each need to be aware of: Large “fluffy” LDL particles (type I), medium LDL particles (type II & III), and small dense LDL particles (type IV).
Weight & Size of VLDL, LDL & HDL
Why LDL-C is misleading: Identical LDL-C of 130 mg/dL can have a low risk (Pattern A) with a few “big fluffy LDL particles or high risk (Pattern B) with many small dense LDL particles.
Second, it is important to realize that HDL and LDL types are actually transport molecules for triglyceride – they are essentially buses for the triglycerides (the passengers). HDL can be simplistically thought of as taking triglycerides to the fat cells and LDL can be thought of as taking triglycerides from the fat cells to the muscles and other organs for use as fuel.
Third, it is the small dense LDL particles that are more easily oxidized and because of their size, are more likely to cause damage to the lining of the blood vessel leading to damage and blockage. The large boyant LDL (“big fluffy LDL particles”) contain more Vitamin E and are much less susceptible to oxidation and vascular wall damage.
Eating more fat or cholesterol DOES NOT raise small dense LDL particle number. Eating eggs, bacon and cheese does not raise your cholesterol! What increases small dense LDL particles then? It is the presence of higher levels of insulin. Insulin is increased because of carbohydrate (sugars, starches or fruits) ingestion. It is the bread or the oatmeal you eat with the bacon that is the culprit. The bread or starch stimulates and insulin response. Insulin stimulates the production of triglycerides and “calls out more small buses” to transport the increased triglyceride to the fat cells (4, 5, 6, 7).
Fourth, following a very low carbohydrate diet or ketogenic diet has been demonstrated to decreased small dense LDL particle number and correlates with a regression in vascular blockage (8, 9). So, what does this really mean to you and me? It means that the low-fat diet dogma that that has been touted from the rooftops and plastered across the cover of every magazine and health journal for the last 50 years is wrong. . . absolutely wrong.
