All you caffine junkies...

[lynn]

I was reading recently that caffine increases your insulin sensitivity ...especially when you eat carbs and have it at the same time....and everytime you drink coffee it increases it as well. :shock:

This is making me think twice of cutting back or taking out my coffee ...or at least switching to decaf.

As anyone gone off coffee 100% and had a positive result with respect to increased energy and/or fatloss? :confused:

I drink about 2 cups in the morning and if need be one in the afternoon before workout..but I'm thinking twice now. :eek:

You actually cracked me up.....
I have this mental picture of you strolling down there and throwing a fit when they try to charge you...:lol3:

Actually, I've read the opposite: it can decrease insulin sensitivity.

[smuggie]

Actually, I've read the opposite: it can decrease insulin sensitivity.
That's probably what Lynn meant.

[lynn]

Here's the info...

1) Caffeine intake (in all of its forms) decreases whole body glucose disposal (carbohydrate uptake) by 15-30%.

2) Caffeine intake decreases skeletal muscle glucose disposal by 50%.

3) When consumed with a standard carbohydrate breakfast, caffeine decreases insulin sensitivity, leading to large increases in blood insulin. But even in the face of this insulin surge, blood glucose doesn't disappear at a normal rate. When the body can't take up carbohydrates properly (as when drinking coffee), it releases loads of insulin to help out. However, the coffee actually prevents the insulin from doing this job and you end up with high insulin and glucose. That, my friends, is the serum profile of the obese, type II diabetic.

4) Caffeine decreases insulin sensitivity for at least three hours (this is the duration of the longest study they've performed), but the true duration of the effect isn't known. I speculate that it's at least five hours, the half life of caffeine.

In this case, many people are probably walking around all day with impaired insulin sensitivity. If you're a coffee drinker you should realize that you're living your life like a diabetic except during the times that it could actually be diagnosed. When you go to the doc to see why you're so fat or you feel like crap (if you have any glucose or insulin tolerance problems), what do you have to do? You have to fast overnight and avoid coffee! So 99% of your waking life you're functionally diabetic and that 1% of the time when it really matters and can be diagnosed, you're not. No wonder experts suggest that 50% of North Americans are diabetics who aren't diagnosed as such.

5) In one study, four groups were used to evaluate the effect of caffeine and glycemic index on insulin sensitivity.

o The first group got decaf and a low-GI breakfast. They saw a normal blood glucose and insulin response.
o The second group got decaf and a high-GI breakfast. They saw a bigger insulin and glucose response in the blood.
o However, when the low GI group got regular coffee with breakfast, their blood profile was worse than that of those who got the high-glycemic breakfast and decaf. Therefore coffee/caffeine can turn a low glycemic meal into a high glycemic meal!
o Finally, the group that drank coffee and had the high-glycemic meal ended up looking like diabetics.

6) One interesting hypothesis generated at the seminar was as follows: In terms of insulin sensitivity, caffeine alone is worse than coffee and obviously (as seen above) coffee is worse than nothing. However, some people believe that certain substances in coffee (specific quinides) can actually increase glucose disposal and improve insulin sensitivity. While the quinide content of coffee isn't strong enough to counter the effects of the caffeine, the quinides in decaf coffee may actually increase glucose and insulin tolerance. This hypothesis still needs to be tested and proper doses have yet to be discussed; however, keep your eyes out for this research in the near future.

So the final word on coffee and caffeine is this - stay the heck away from it! The only way to minimize the damage it causes may be to drink your coffee with a very low carbohydrate meal and eat only low carb meals for the next few hours after your coffee intake. I know, I know, it now sucks to be a coffee drinker! But giving up your java may bring you some great health and physique benefits.

Hey Lynn, can you share the link to the source? :hi:

[strongchick]

If you do a pub med search, there are lots of articles on caffeine and insulin resistance.

[Naggy]

So it's TRUE!?! :bawling: :bawling: :sad0116:

It's a sad day for Naggy...

[Audrey]

I would say a lot depends on your coffee consumption and like for a lot of things, it is a question of moderation. A little coffee (something like a cup a day) is probably no big deal. 4-6 cups a day... I would cut back on it (high caffeine intake = elevated catecholamines).

Waa waa caffeine decreases insulin sensitivity.

How do people honestly think what happens with Ephedrine and caffeine supplements? I suppose ephedrine causes diabetes too huh?

Insulin sensitive is not always a good thing.

Fuck, coffee is associated with a DECREASED risk of diabetes

Caffeine is associated with DECREASED fat mass.

Resistance training can DECREASE insulin sensitivity too, ya better stop doing that.

For a better explanation


Insulin sensitivity within a normal healthy population operates within a range. Typically the sensitivities would be a bell curve, or at least normal after transformation (std statistical manipulation to create a normal sample, due to biological measures typically being skewed).

The term Insulin Resistance is a state that will be a defined part of this curve, that shows where the normal range end and the diabetes range begins. Due to sensitivity and specificity of a range, there will be some false positives and negatives in the population, but the cutoff is set to minimise these.

If somebody's senstivitity to insulin increases, then for a given quantity of insulin, you get MORE effect. So you get more glucose uptake, you get less fat oxidation/lipolysis yada yada yada.

Within normal healthy people with a normal health range of insulin and the sensitivity to insulin, fasting levels of insulin blunt lipolysis and fat oxidation.

If you are more senstive, and you are fasting, you will have less fat released and burnt, because fasting insulin doesnt decrease by a lot.

This happens when dieting. Due to the consistent energy deficit, the cells cry out for food, so they increase sensitivity to try and scavange as much food as possible. But fat cells also try and do this, because they want to stay fat. Part of teh bodys system to prevent starvation and why it can be harder for a lean person to lose fat. because the body doesnt want to.

If you lose sensivitiy, the body can increase insulin output far better to maintain status quo of normal glucose tolerance. When your pre-diabetic, or with impared glucose tolerance, and insulin resistant, things have gone on too long and stressed the shit outta the system. This is predominant in typically fat as fuck inactive people, and their sensitivity to insulin has long ago left the normal range and gone to retard land.

There are lean people who achieve this as well, but typically they have inflammation issues (so do fat people but different causes... inflammation reduces insulin sensitivity all on its own).

Caffeine stimulates release of epinephrine, or adrenaline depending on your side of the world, amongst the overall catecholamines. Caffeine also prolongs their effects. Ephedrine stimulates the catecholamines as well. Caffeine and ephedrine are synergistic with each other. Combined, these will reduce insulin sensitivity quite nicely. Less insulin effect, more fatty acids being released from the cell, more fat being oxidised, more fat being lost. (without going into the mental stimulation effects)

Resistance exercise can create muscle damage, which inhibits the translocatioon of Glucose transporters from the cell, and part of how insulin works is by stimulating the translocation of these transporters, to carry glucose into cells.

The effect of caffeine on insulin sensitvitiy is there, but the actual significance of it appears to be minimal. If your a healthy active adult eating reasonable quantity of food, its even less important.

Potentially one of the best concepts is having overall muscle sensitive and fat cells insenstive (i still question that concept :)). But the only thing that appears to do this consistent energy depleting exercise, and fish oils.

Great explanation Aaron.

I knew coffee and caffeine had to be good for you. It just had to be.

[fluteangel]

Great post and great explainations, but for those of us slow on the understanding, may I ask for a little clarification? This is what I"ve gotten out of several posts:

1) caffeine PWO is good to help glucose uptake (it would appear) and recovery?
2) caffeine pre-workout is good as it stimulates fatty acids burned for fuel, not to mention energy

With regard to insulin sensitivity - I've read that having caffeine WITH a low-glycemic meal actually turns the meal into a high GI meal. Is this necessarily something I should concern myself with or not even worry about caffeine in the slightest?

Article for reference:
Cup of coffee with your cereal sends blood sugar soaring
Canadian team finds caffeine with carbohydrates makes body insulin resistant
Sharon Kirkey, The Ottawa Citizen
Published: Tuesday, May 20, 2008
Eating low-sugar cereal may seem like the healthy choice, but drink a cup of coffee before breakfast and you might as well go for the chocolate corn pops.

Canadian researchers say drinking coffee before eating your morning cereal can affect the body's blood-sugar response and cause blood glucose levels to rise dramatically - especially when eating low-sugar cereals.

According to the study by University of Guelph researchers, blood sugar levels in people who ate low-sugar cereal were 250 per cent higher if they drank caffeinated coffee before or with breakfast, compared to decaf.

Earlier research has shown that, "whether you're a healthy individual, obese or a Type 2 diabetic, when you ingest caffeine and then follow that with some food that's carbohydrate-based, for a prolonged period of time -- certainly six hours at least -- your body becomes insulin resistant," says Terry Graham, professor of human health and nutritional sciences at the University of Guelph.

For his study, Mr. Graham's team had 10 healthy men drink caffeinated coffee, decaf or a placebo (water) one hour before eating breakfast.

The coffee drinkers each drank roughly two cups of coffee.

Then, on different days, the men ate either cereal with low levels of sugar (in this case, All-Bran) or a moderately sugary cereal (Crispix). Blood samples were taken over several hours to check for caffeine levels, blood sugar (blood glucose) and insulin responses.

"What we found was that both the resistance to insulin and the levels of glucose and insulin went up dramatically with either cereal if they had caffeinated coffee before the meal," Mr. Graham says.

What's more, the men who had coffee before eating the low-sugar cereal had higher blood-sugar levels than those who drank decaf before eating the sweeter cereal.

"In other words, if you thought you were being a very good person and looking after your health and avoiding the sweeter cereal and taking the low one, and then saying, 'Of course, I'll have my cup of coffee with it,' in fact your body was seeing something that was greater than if you had the sweeter cereal without coffee."

"It's the caffeine in the coffee that is altering your body's sugar response," Mr. Graham says. "It makes us resistant to insulin, which in turn makes our blood-sugar levels go higher."

The study appears in the most recent issue of the American Journal of Clinical Nutrition.

For healthy people, the implication is "no big deal," Mr. Graham says. "If my glucose goes a bit higher and I'm over it in a couple of hours, I'm happy and I've had my coffee."

The same doesn't hold for obese people who are sedentary and don't get any exercise. These people are already insulin resistant and at risk for Type 2 diabetes.

"For those people who suspect they're at risk, or are at risk or have diabetes, the caffeinated coffee with any cereal, anything that has carbohydrate in it, you are going to be experiencing a much bigger surge in blood glucose and your body will try, and hopefully can, produce enough extra insulin to manage it," Mr. Graham says.

He's not knocking coffee. Recent research shows "very clearly" that heavy coffee drinking decreases the risk for Type 2 diabetes.

Coffee contains many positive biological compounds, including antioxidants, and decreases the risk for diseases of the gut.

"In the long term, consuming coffee for decades decreases your risk," Mr. Graham says.

The obvious thing to me is, drink decaf. You'd have all the good and you wouldn't have the transient hit of caffeine."

Although this study included men only, Mr. Graham said he has unpublished data showing women, as well as older, middle-aged and overweight people, and diabetics, respond in a similar way.
