Does Coffee Make You Gain Weight?
Coffee is a popular beverage that you’d probably drink health benefits or not. But with research suggesting it could impair glucose tolerance, increase insulin resistance, and cause you to gain weight, you may need to dig deeper. Your best bet to avoid caloric coffee pitfalls is to leave out the cream and sugar and have no more than 400 mg (3-4 cups) of caffeine per day.
Coffee is that perfect pick-me-up, and powers so many lives the world over. The caffeine kick is exactly what you need when your energy is ebbing, and it’s quick and easy to whip up anytime, anywhere. But reports that it could cause weight gain may now put a spanner in the works.
Weight Gain From Coffee
Coffee, when consumed in large quantities could actually be counterproductive to your weight loss efforts, if latest reports are to be believed. An Australian study revealed that CGA(chlorogenic acid), a polyphenol found in coffee could prevent fat loss from your body. It could even cause insulin resistance to develop. The research that made coffee lovers and the research community sit up, suggested that coffee’s benefits may be connected to how much you drink. While moderate amounts of up to three or four cups a day might even help lower cardiovascular disease or type 2 diabetes risk, having just a couple more (five to six) can cause you to see problems like insulin resistance and higher levels of glucose intolerance.1 When test animals were fed a high fat diet along with CGA, not only did they not lose weight, but they actually developed insulin resistance and saw more lipid accumulation in the liver than mice not given CGA.2
Reduced Glucose Tolerance And Insulin Resistance
The issue with caffeine intake is possibly the glucose intolerance it is said to cause immediately after being consumed.3 Unfortunately, impaired glucose tolerance is one of the high risk factors for type 2 diabetes to develop.4 When your body struggles to manage its sugar levels and insulin levels properly, as with a person who has diabetes, it is easy to gain weight. Coffee’s connect to insulin resistance is also a potential problem, because metabolism hormone insulin is responsible for regulating blood sugar levels, appetite control, and even fat storage. If you have too much insulin in your body, your food begins to get stored as fat cells – bad news for those trying to lose weight or stay fit.5
The Stress-Sleep-Weight Gain Nexus
What coffee can do to your body, is keep you alert and “buzzing” making it difficult to fall asleep. With reduced sleep time, your cortisol or stress hormone levels rise. Now increased stress levels and reduced sleep have both been connected to weight gain in various pieces of research, and that could well be why some people notice weight gain linked to coffee consumption.6 A cup of coffee with about 400 mg of caffeine in it(a 16 oz cup has around 500 mg) as early as six hours before bedtime can be disruptive to sleep.7 Chronic sleep deprivation can make you feel more tired and hungry and make you eat more as appetite and satiety controlling hormones like ghrelin spike during the day.8
Consuming over 200 mg of caffeine can also worsen anxiety for those already predisposed to it and bring on a negative mood that could also meddle with sleep. Added to that is the fact that caffeine consumption can cause your body to produce cortisol even when it is not under any real stress. So that cup of coffee could effectively simulate stress responses in your body and worsen sleeping trouble.9 Reason enough to watch how much you’re having!
Is It The Coffee Or What’s With It?
If coffee on its own isn’t the offending substance, then it could be due to what you have in your coffee that you’re gaining weight. If you knock back several large cups a day, then the sugar or milk you add to it could also be pushing your weight up. Just one spoon of sugar has about 16 kcal10, half a cup of reduced fat 2% milk has 50 kcal11 Switching to black coffee without sugar might help, or cutting back on the amount of sugar you consume in each cup and trading in regular whole milk for skim or low fat variants.
Not Everyone Agrees
So coffee may be linked to weight gain. Yet, evidence to the contrary exists in other studies evaluating the effect of coffee on weight gain. In one piece of research where the effects of coffee intake on adolescent girls were studied, researchers found no impact from drinking the beverage(as opposed to alcohol consumption which was linked to weight gain). Another study using data from food diaries kept between ages 9 and 19 by girls participating in the National Heart, Lung, and Blood Institute Growth and Health Study12 too found similar results with coffee not being implicated in weight gain. Researchers went as far as to suggest that coffee might even help with weight loss.13 In general, caffeine is seen as a thermogenic ingredient that can actually help boost your metabolism and could even help to prevent obesity.14
How Much Is Okay?
For normal healthy adults, having up to 400 mg of caffeine a day should be fine, taken in single doses of under 200 mg at a time. However, do keep in mind the possible effects on your sleep and keep a good distance between that last cuppa and bedtime, or switch to a decaf version. And as the researchers in the Australian study say, it is the dosage that makes all the difference, so avoid crossing the 3 to 4 cups a day levels at any cost.
