6 Incredible Effects of Giving Up Coffee For a Month, Say Dietitians

Kicking your caffeine habit might not be so daunting with the possibility of these benefits.
FACT CHECKED BY Kiersten Hickman

From kickstarting your morning to providing an afternoon pick-me-up, drinking coffee is a tried-and-true way to get a much-needed boost of energy. Although coffee consumption is tied to a range of benefits—including decreased risk of various diseases, increased metabolism, and improved mood—there are also some less appealing side effects. These include increased heart rate, heightened anxiety, and irritable bowel symptoms.

Kicking your coffee habit may initially sound quite daunting, due to the possibility of withdrawal symptoms like headaches, moodiness, and fatigue. However, there are several major benefits worth noting.

To get the breakdown of the effects of giving up coffee for a month, we consulted our medical expert board members Tammy Lakatos Shames, RDN, CDN, CFT, and Lyssie Lakatos, RDN, CDN, CFT, also known as The Nutrition Twins. Read on to learn more about how breaking up with coffee impacts your body. And for more, don't forget to check out The #1 Best Juice to Drink Every Day.


Better sleep

Caffeine is a stimulant, which means it speeds up the activity in your brain and nervous system. While this can help keep you alert during the day, it may end up disrupting your sleep cycle at night, ultimately causing drowsiness the following day. This can even be true if you drink your coffee at least six hours before going to bed, the Nutrition Twins say.

Giving up caffeine could reverse these effects, allowing you to not only get more restful sleep but fall asleep in a shorter amount of time.


Decreased risk of tooth decay

In addition to being notorious for staining teeth, coffee is known for weakening them, as well.

"…the caffeine in coffee can cause dry mouth, and saliva fights bacteria. So, the drier your mouth is, the greater risk of cavities," say the Nutrition Twins.

Studies also show that highly acidic drinks can result in enamel wear and decay. Given the high acidity of coffee, skipping out on your daily java could promote healthier, whiter teeth.


More youthful skin

Although coffee beans are packed with free radical damage-fighting antioxidants, the skin-promoting benefits are primarily obtained through topical products. In fact, drinking coffee has been suggested to have possible skin aging effects.

In particular, the caffeine slows down the rate at which the body produces collagen—the protein that keeps your skin elastic, the Nutrition Twins say. When the amount of collagen is decreased, the skin starts to sag, and wrinkles form.


Lower blood pressure

"Blood pressure rises after having caffeine, and this may be especially true with a younger population," the Nutrition Twins say.

According to the Mayo Clinic, some researchers think caffeine could block a hormone that helps your arteries widen, while others believe caffeine triggers the release of adrenaline, which causes blood pressure to spike. Cutting caffeine could help combat these effects.


Better nutrient absorption


According to the Nutrition Twins, "You may be able to absorb your nutrients better." Studies show that the caffeine in coffee can interfere with the absorption of nutrients, including B vitamins and minerals like calcium, iron, and magnesium.


Weight loss

While black coffee contains virtually no calories, it's not the most popular option. Sugar, syrup, and high-calorie creamers might make your bean juice taste better, but they can also increase the likelihood of weight gain.

"For many, their daily one-to-two cups of coffee may be adding more than 500 calories a day, which could result in roughly a one-pound weight loss each week that you cut it out," the Nutrition Twins say. "Plus, by reducing consumption of sugar and cream, you ingest less inflammation-promoting foods."
