How do you start your morning off? Mine begins with a steaming hot cup of my favorite coffee. The black nectar also accompanies my workouts, my busy evenings when I have to work late, my headache treatments, and even my post- workout recovery shakes. ![]() I know I am not alone in my love for coffee. In the past 6 decades, researchers have conducted more than 2. That’s an average of one new study a day! If there is a disease then chances are that someone has already tried to link the effects of caffeine to it. Cancers, heart disease, infertility, brain malfunction, asthma, migraines, gallbladder disease, attention- deficit hyperactivity disorder, high and low blood pressure, diabetes and obesity have all been on the list. You have probably been warned to stay away from drinking too much coffee and given tips on how to gradually get off the java, but is it worth the effort to cut back and even quit? Hold onto your mug and keep reading! ![]() ![]() Calorie- Free Insulin Surges. The problems regarding coffee’s impact on blood sugar and insulin levels have been brewing for a while and the arguments are steaming on both sides. Short- term metabolic studies have shown that caffeine intake can acutely lower insulin sensitivity and sometimes even raise blood sugar levels. One study published in “Diabetes Care” found that consuming 7. The researchers suggested that such results reflect decreased insulin sensitivity from high caffeine intake. What’s worse is that after just 5 days of regular supplementation, the body’s blood glucose control system may become tolerant to the effects of caffeine. If, for whatever reason, you would want to get off the bean, be aware that a sudden withdrawal can cause severe headaches, irritability, anxiety, depression, drowsiness and fatigue. Should you worry? Absolutely not! A growing body of evidence suggests that a habit of drinking a lot of coffee every day is associated with higher insulin sensitivity and a lower risk for type- 2 diabetes. After analyzing data on 1. Harvard researchers calculated that when compared to people who do not partake in drinking coffee, those who consume 1- 3 cups of caffeinated coffee daily can reduce their diabetes risk by up to 1. Having 6 cups or more each day slashed men’s diabetes risk by 5. Coffee’s way of life once it gets into our bodies is very interesting. You enjoy your favorite cup of java and for a few hours after you feel energized, awake and happy while burning up extra fat stores and being in the insulin resistant state. If you repeat this morning java habit day in and day out, within several months to a few years, your insulin sensitivity is heightened and your risk of developing type- 2 diabetes goes down significantly. How can we explain this? Coffee has caffeine, but its effects are somewhat different from the pure chemical. The beans are loaded with antioxidants, a group of compounds called quinines, tocopherols, and magnesium, all of which are shown to improve glucose metabolism and the body’s response to insulin in clinical settings. Chlorogenic acid (also found in blueberries) and trigonelline (also found in peas, lentils, soybeans, and sunflower seeds) are two of the major phytochemicals in coffee and have been shown to decrease blood glucose and insulin concentrations in the blood compared to a placebo after ingesting sugar. It is likely that these two powerhouses increase insulin sensitivity.
Wow, way to go coffee! Jacked Up Workouts. Coffee and other drinks with its active stimulant caffeine (or the herbal counterpart Guarana) can help delay fatigue, contribute to increased alertness and faster reaction time. This provides an outstanding mental boost which is famous for helping athletes through vigorous training sessions. Science has established that caffeine has numerous physiological and psychological effects on the central nervous system and it easily crosses the blood- brain barrier where it blocks the relaxing neurotransmitter adenosine by binding to its receptors on the surface of cells without activating them. By doing so, caffeine “excites” the nervous system and has been shown to numb the pain, increase heart rate and stimulate the release of adrenal hormones (epinephrine, norepinephrine and cortisol) which may help you crank up your workout intensity and get that last extra rep while postponing fatigue, decreasing the perceived difficulty of the exercise and allowing you to leave the gym without feeling exhausted. This is why I add a couple of espresso shots to my pre- workout shake! Although caffeine is not a carbohydrate and has zero calories, it does stimulate the pancreas to secrete a small amount of insulin, particularly if you are prone to insulin resistance and hyperinsulism. The reason this happens is because drinking coffee enhances the effect of two hormones, adrenaline and glucagon, which release stored sugar (glycogen) from the liver and a small amount of energy from fat stores resulting in higher blood sugar and elevated insulin. By this mechanism, caffeine decreases insulin sensitivity. However, this happens only for a brief period of time and is a normal biological response. Adrenaline and glucagon also go up when you are stressed or during exercise. Even a simple walk will decrease insulin sensitivity, but nobody has had insulin resistance from exercising. If anything, physical activity is praised for its impact on adrenaline and noradrenaline since these chemical messengers get body fat moving from stored places to the bloodstream. ![]() From here, it’s a short trip for the fat to get out of the system and then you can easily use it as fuel. As it turns out, the caffeine- induced insulin resistance is just a result of increased circulating free fatty acids which can be burned off during your workout. For that matter, coffee has been used for years by endurance athletes, bodybuilders, boxers, powerlifters and other athletes. It has been researched as an excellent thermogenic, which is a type of supplement which may help burn body fat. In case all of the above benefits are not enough justification for you to enjoy a hot cup of Joe, here is another important reason why you may want to add a cup into your workout arsenal. ![]() ![]() A caffeinated body may burn calories at a higher rate! The black nectar gives you a nice punch at the gym, so your intensity is super high, plus it stimulates a cascade of hormones that release free fatty acids into the bloodstream causing the body to burn fat while sparing carbohydrates to use as energy. Subjects who consumed 3. ![]() Another study found that the caffeine in 2 cups of coffee may cause an average woman to expend up to 5. The important part here is exercise which is not a revelation, I know, but it’s an important point. Nobody loses fat using caffeine supplements alone and you are much better off drinking coffee before your intense workouts than drinking a cup while sitting on the couch watching TV. One terrific thing you can get from training while on some caffeine is that the temporary dip in insulin sensitivity primes the body to become even more responsive to nutrient intake afterwards. Think about it this way. When you train, the body wants to get rid of fuel from fat cells, but also increase its ability to take in and replace what is lost as fast as possible afterwards. The fat cell’s “machinery” is not designed to store and release fuel at the same time, which would be counter- productive. Put differently, during training and after caffeine ingestion, you are in an insulin resistant state which is replaced by an insulin sensitive state once the activity or the action of the caffeine stops. This premise is the reason why you are advised to refuel within an hour after finishing a workout since muscle cells become extremely sensitive to insulin and the nutrients carried by the hormone, and thus, can soak up the food like a sponge. Regardless of whether you train in the caffeinated state or not, exercise itself reduces the detrimental effects of caffeine. A body in motion depends on a special metabolic pathway, called non- insulin dependent glucose uptake, which literally negates any insulin- related disturbances caused by the stimulant. You already know that nothing beats a good workout for fat loss and muscle gain. So, bodybuilders shouldn’t worry about their stimulants or insulin fluctuations from consuming caffeine. As a matter of fact, caffeine can serve them well in helping store glycogen which is the primary fuel for muscle. Java- Spiced Recovery. For the first time, researchers from the Garvan Institute of Medical Research in Sydney, Australia showed that a small group of 7 well- trained endurance cyclists who ingested caffeine (8 mg per kilogram of body weight which is the equivalent of drinking 5- 6 cups of strong coffee) along with a carbohydrate had 6. For the entire 4- hour recovery period, the caffeinated drink resulted in higher levels of blood glucose and plasma insulin. Hawley, the study’s senior author. Researchers also noted that 1 hour after exercise, muscle glycogen levels had replenished to the same extent whether or not the athletes had the drink containing carbohydrates and caffeine or carbohydrates only. It looks like coffee may supply a longer- lasting effect to carry you through your next workout. Now, that may seem like a breakthrough concept, but here’s the deal. Let’s not discredit the fact that the number of participants in the research study was rather small, the caffeine dose was very high, and most of us do not ride in the same highly trained bike camp. Additionally, nobody is going to achieve that level of glycogen absorption within a day after a workout. I think that the only reason for you to add caffeine to your post- workout meal would be if you are going to exercise again within 4 hours after the first workout. Even if you’re training every day, you have 2. Fast. Stats - Diet/Nutrition. Data are for the U. S. Mean carbohydrate intake for men (% of kilocalories): 4.
