This is your body on caffeine
Wednesday, January 27th, 2010For some people, morning just wouldn’t be morning without an extra large coffee and glazed donut. It’s a habit many can’t break judging from the drive-thru line at Tim Horton’s that blocks traffic and adds to my commute.
Caffeine is the most widely consumed drug in North America and is enjoyed for its flavor as well as its mood and “energy” enhancing properties. However, from a weight loss standpoint, it’s a double-edged sword.
In favor of weight loss, caffeine, when taken in moderation, is ergogenic meaning it boosts the body’s ability to do work. Hence, a pre-workout java could help you exercise longer or harder thereby increasing energy expenditure which can help you to lose weight. Caffeine is also a mild diuretic for those who have not developed a tolerance for it. This means it can help you drop “water weight”, but only if you are not a regular coffee drinker who has already become immune to this effect. Many weight loss supplements contain caffeine for these reasons.
On the down side, chronic caffeine consumption promotes insulin resistance, a condition which precludes type 2 diabetes. In this situation, the body is producing lots of insulin but the insulin receptors on cells are not sensitive to its effects. People with insulin resistance often consume a high carbohydrate diet (i.e. donuts) which dumps glucose into the bloodstream to further stimulate insulin production. More insulin causes insulin receptors to tune out even more causing glucose to build-up in the bloodstream and trigger more insulin production…you see the vicious cycle. As their bodies are not using glucose efficiently, people with insulin resistance often struggle with weight loss.
There are pros and cons when it comes to caffeine and weight loss. You really need to listen to the feedback your body gives you. Pay attention to how you feel when you drink coffee, tea or caffeinated soft drinks. Do you feel good for a little while, then shaky and irritable? Do you notice more pain or other kinds of inflammation after prolong caffeine use? For more information on how caffeine affects your body, check out Precision Nutrition.
