A Coffee Cleanse for Weight Loss Is Not Just an Urban Legend

At first glance, "coffee" and "weight loss" don't seem like words that belong together in the same sentence. But whether you love it hot or iced, coffee is about to become your go-to new diet drink.

Inspired by exciting evidence that an ordinary cup of joe can help increase a person’s odds of a long life by up to 50 percent, former NBC Nightly News and 60 Minutes medical correspondent Bob Arnot, MD, began experimenting with ways to reap the drink's maximum benefits. The result: A whole new way to detox, one built around special coffee (both regular and decaf, hot and iced) that boasts the highest doses of disease-and-fat-fighting antioxidants. To date, folks testing Dr. Arnot’s “coffee cleanse” have been able to treat everything from eczema to type 2 diabetes while shedding up to 50 pounds in 50 days. “Drink coffee my way, and you can trigger unparalleled weight loss while changing your entire life for the better,” Arnot said.

Does coffee help you lose weight?

After studies from the National Institutes of Health pointed to antioxidants in coffee (which are called phenols) as key to the drink’s many health benefits, Arnot was curious about which brew options were highest in phenols. He was shocked to find no comprehensive tests existed, so he hired chemists at a Vermont lab to systematically rank hundreds of beans.

“Dark roasting destroys phenols,” Arnot said, adding that he and his team took to calling the lightest roasts “lean roasts,” because they explode with slimming compounds. Plus, unlike their dark counterparts, they “are delicious without fattening sugar or cream.” Further down you’ll find a list of top-ranked “lean roast” coffees, including options from Starbucks, Dunkin’ Donuts, and even McDonald’s. We're also sharing a special version of Arnot’s coffee cleanse, which pairs lean roast coffee (at least three cups per day) with nutrient-dense shakes and meals that he says optimize coffee’s benefits. But whether you use his detox regimen or not, every cup of high-phenol coffee you sip will give you a fat-fighting edge.

How High-Phenol Coffee Slims

High-phenol coffee affects the body by giving you...

A faster metabolism. According to a preliminary Japanese study, phenols cause a short-term burst of faster calorie burning. Phenols also boost calorie burn long term by preventing a type of inflammation that not only stalls our thyroids, but can also lead to loss of metabolism-boosting muscle. Bonus: Stimulants in even a single cup of caffeinated coffee “are proven to increase metabolism by an extra 75-100 calories a day,” Arnot said.

Faster fat burning. Phenols in coffee have been shown to lower levels of insulin, a very good thing since the hormone blocks fat burning. The less insulin we make, the more readily fat burns! Phenols have also been shown to decrease the formation of new fat, Arnot said. Another caffeine bonus: The stimulant helps free fat from fat cells during activity, so the body can quickly incinerate it. “It’s a phenomenal boost to weight loss!”

Fat and calorie blocking. There are actually a couple few different types of phenols in coffee. One type, chlorogenic acid, has been shown to decrease our absorption of carbs, so some calories from, say, the bread we enjoy with coffee won’t count. Meanwhile, Arnot noted, another phenol called melanoidin decreases absorption of dietary fat — meaning even more calories don’t count! He added: “I suspect it’s the reason people instinctively reach for coffee after a rich meal.”

Results From the Coffee Diet Plan

New Jersey mom Marney Rohda, 48, was among the first folks to volunteer to test Arnot's coffee cleanse. Eight weeks later, she was 20 pounds skinnier. "I never drank coffee regularly before. Now I'm hooked!" she said. Then there's fellow New Jersey mom Gloria Culmone, 47. Upping her coffee intake to five high-phenol cups a day, she dropped 15 pounds in 21 days. "I'm not sleepy in the afternoons anymore, my cravings for unhealthy foods went away, and maintaining my weight loss has been easy," she said. "The right coffee can do amazing things."

The Coffee Cleanse Meal Plan

High-Phenol Coffee: Sip one cup upon rising and unlimited additional cups per day as desired, aiming for at least three cups. Enjoy coffee decaf or regular, hot or iced as desired. High phenol coffees include:
