Is Coffee Making You Fat?
Coffee can trigger weight gain

The cover of Woman’s World magazine asked “Is Coffee Making You Fat?”

Every woman who glanced at this magazine cover, asked herself, “Could that be true – can coffee actually make you fat?”

Scientists have verified that, YES, coffee can make you fat.

Though coffee has a reputation for providing energy, it also has a down-side. It can trigger weight gain. New York restaurant owner, Drew Nieporent, shed 120 pounds by simply giving up coffee, after he discovered that his coffee habit has largely contributed to his considerable weight gain.

Dainn Smith was advised by her nutritionist, Therese Franzese, R.D., to gave up her coffee habit. As a result, Diann dropped 4 dress sizes.

Hollywood actress, Merilu Henner had gained 45 pounds. After reading about coffee’s fattening properties, and coffee’s ability to stimulate appetite, Merilu decided to give up coffee. “Studies show that people who drink coffee tend to eat a fatter diet” stated Merilu. She was pleasantly surprised to find that she regained her girlish figure after swearing off coffee.

Researchers have clearly identified the biochemical culprits in coffee that trigger weight gain. The culprits are the disruptions in glucose metabolism that impairs blood glucose homeostasis, which is caused by drinking coffee. These disruptions trigger the fat-storage hormones, insulin and Lipoprotein Lipase (LPL).

It has been established and clinically proven that coffee and/or caffeine increases the body’s release of insulin and LPL, the main fat-storage culprits.

In a large study, coffee was also shown to increase the consumption of very fattening and fatty foods. This is due to the reactive-hypoglycemic properties of coffee. This explains why coffee triggers uncontrollable cravings for donuts, and other fattening foods, which are very high glycemic, and fat-storing. These finding are consistent with published clinical trials and research in humans showing that glucose metabolism is impaired shortly after the ingestion of caffeine, brewed coffee, ground caffeinated coffee, or instant caffeinated coffee:

Even decaf coffee can trigger fat gains. Gillian Anderson used to drink Starbucks decaf coffee four-times-per-day, in an effort to lose weight. Instead of losing weight, she gained 10 pounds. When she stopped drinking the Starbucks coffee, Gillian became slim again.

Drinking regular coffee also causes the secretion of the hormone Cortisol, a stress-hormone and biochemical marker of stress, that triggers belly fat accumulation. Dr. Henry Kahn, of Emory University School of Medicine states, “There’s something about fat cells in the body – the way they respond to stress hormones. People with high levels of stress hormones have a tendency to store fat in their bellies.”


The biochemical disruptions causes by drinking coffee and/or caffeinated drinks (such as energy drinks) are related to its Glycemic Properties. Coffee elicits an acute insulin-insensitive environment in both healthy and obese individuals, and in type 2 diabetics (AJCN/2008).

Coffee and caffeine-containing drinks, mediates negative effects on glucose tolerance and glucose homeostasis in humans via adenosine receptor antagonism, and impairment of insulin-mediated glucose uptake via caffeine-stimulated epinephrine release. Both coffee and caffeine stimulate the release of epinephrine, which exerts actions opposite to that of insulin via Beat-Adrenergic stimulation.

This biochemical cascade causes negative effects on blood glucose homeostasis, and belly fat gains.

In diabetics, coffee and caffeine-beverages have adverse effects on glucose metabolism, producing higher average daytime glucose concentrations and exaggerated post-prandial glucose responses.

80% of Americans consume coffee and caffeine-containing products every day, with 60-75% of all caffeine ingested coming from coffee. Though researchers have identified the fat-storing effects of coffee consumption, they did not offer a solution other than avoiding all coffee and caffeine-beverages.

Researchers at Duke University Medical Center (2008) stated that “Daily consumption of coffee, tea, or soft drinks raises blood sugar levels and may even hinder efforts to control the condition.”

The Duke University researchers recommended “Simply quit drinking coffee, or any other caffeinated beverages.”

On a more positive note, Harvard Medical School and the Harvard School of Public Health stated “Drinking three or more cups of coffee per day may reduce the risk of ovarian cancer by over 20 %.”

The benefits of coffee have been clearly demonstrated in thousands of clinical trials that are un-related to weight gain and glucose homeostasis. The health benefits of coffee are profound, and the only drawback is the triggering of weight gain, increased belly fat, and glucose imbalances.


Since coffee has multiple health benefits, the only obstacle to enjoying coffee has been its propensity to add body fat and weigh gain, and disrupt glucose metabolism.

This dilemma was solved when renowned glycemic researcher, Dr. Ann de Wees Allen, Chief of Biomedical Research, came up with a solution.

Dr. Allen received the first glycemic patent ever awarded worldwide, when she developed and Patented the mechanism for correcting coffee and caffeine. This Patent and research was awarded “Breakthrough Product of the Year” by Success magazine and featured on the front page of the Wall Street journal.

Named as the leading glycemic specialist in the world, Dr. Allen applied her extensive knowledge on the glycemic index, the Cephalic index, obesity, Lipoprotein Lipase, fat-storing hormones, and adipose tissue fat-storing, to the coffee-dilemma.

The result is Patented Skinny Science® Coffee, the only coffee of its kind in the world.
