Consuming a good portion of your daily carbohydrate intake during breakfast time is pretty sound advice. For starters, your body is in an excellent state to process carbohydrates early in the morning. Along with that, your body’s glucose tolerance and insulin sensitivity are also at their peak. But there is something that can disrupt all of that and it may be hard to believe what it is – caffeinated coffee. Here’s why you will want to trade in that daily, sometimes necessary cup of caffeine for some decaf, at least.
When consuming caffeinated coffee along with a good portion of your daily carbohydrate intake, your body’s morning ability to better process carbs and increased glucose tolerance and insulin sensitivity gets sabotaged. Normally, all of those things start decrease from their morning peak throughout the day but coffee is quick to sabotage them earlier on. In the end, if you are working toward eating right by following the advice of consuming a good portion of your daily carb intake during breakfast, coffee may be your biggest obstacle toward those weight loss goals.
There have been a few studies that have demonstrated the effects of coffee. One of the studies published in the American Journal of Clinical Nutrition titled, “Caffeinated coffee consumption impairs blood glucose homeostasis in response to high and low glycemic index meals in healthy men” (Moisey LL, et al., 2008), observed 10 healthy men throughout 4 trials in a randomized order.
The men ingested either 5 mg of caffeinated coffee or the same amount decaffeinated coffee followed by an either high or low glycemic index cereal which provided 75 g of carbs. Testing their tolerance afterward, the study found that ingesting the caffeinated coffee with either a high or low glycemic index meal impaired the management of blood glucose and insulin sensitivity compared to the ingestion of decaffeinated coffee.
When insulin sensitivity decreases along with glucose tolerance, that greatly slows down the fat burning process. Instead, more fat gets stored and that can be very detrimental to any work you put toward your weight loss goals. In the end, the best idea may be to avoid caffeinated coffee when you know you are going to consume a larger amount of carbohydrates during breakfast time.
