Coffee really can be in the way of weight loss. How is that possible? Coffee, your favorite drink? It happens through your hormones. Basically everything in your body functions through your hormones and all hormones are connected to each other. This means that if one of your hormonal systems is out of balance, say for example your thyroid isn’t functioning properly or you have too much stress, it’ll affect all of your other hormones and bodily functions.
The way coffee can inhibit you from losing weight is through the stress reaction it creates in your body. Depending on how much coffee you drink, you might be causing many stress reactions to your body everyday! This reaction is based on caffeine so if you drink a lot of other caffenated beverages like sodas, the same thing is going to happen. Even green tea has caffeine in it (about a third the amount as in coffee) but its effects are buffered by the green tea’s theanine. (Accidentally Over-weight, Dr. Libby Weaver)
Caffeine is also going to stay in your system for a long time. It takes about 3-5 hours for the caffeine in your body to be reduced by 50% and the rest can stay in your system for days. There are individual differences in how fast your body metabolizes caffeine depending on among others your age, weight, environment and genetics. Some of us might get rid of it as fast as 8 hours but for some it can take over two days!
So what if you drink coffee on a regular basis and your body is never without it?
- Coffee affects your sleep. Even if you can manage to fall asleep easily and sleep all through the night, you’re not going to get deep sleep. This is because the caffeine in your system is telling your adrenal glands to pump out adrenaline, which will keep your body vigilant. Your energy levels aren’t going to be optimal and you’ll most likely be tired, because your not sleeping deeply enough. This in turn leads to you craving food due to your hunger and satiety hormones, ghrelin and leptin, being out of wack from being tired. Your going to especially crave carbs and sugar, because your body knows it’ll get a lot of quick energy from those foods. Your body thinks your starving, because when you’re tired your hunger hormone levels rise and satiety hormone levels drop.
- Coffee (or caffeine) makes your adrenal glands secrete adrenaline, your short term stress hormone. This puts your body into fight-or-flight mode from just having a cup of coffee! If you’re already stressed, because you have a busy life with too much to do and too little time, coffee is going to make your situation a lot worse. Adrenaline signals to your liver and muscles to dump out their stored sugar, because you need energy quickly (so you can run away from the tiger that ’s chasing you – yes, your body works in primitive ways). Now your blood stream is flooded with sugar. This sudden increase of sugar in your blood means that your pancreas has to start producing insulin to get the blood sugar down. Insulin, on the other hand, is basically your fat storage hormone, because it puts the sugar from your blood first to your muscles and then the excess is stored in your fat cells. Not good in terms of weight loss. (Accidentally Over-weight, Dr. Libby Weaver, Eat Fat, Get Thin, Dr. Mark Hyman)
This is how coffee alone can stand in the way of your successful weight loss. It puts your body into stress mode, affects your energy levels (because you’re more tired due to not sleeping properly, and then you need coffee to stay awake) and then you crave something sweet. Sound familiar? This is a picture out of my life until i fully understood all the ”not so nice” things coffee does in my body. You don’t have to give up coffee entirely if you don’t want to, but it would be good to cut back on how much you consume. If you can cut back to one cup a day, for example at breakfast, you’ll give yourself a better chance at successful weight loss.
