Coffee for Health and a Leaner Stronger Body

Published on 28th Nov 2019 at 09:45 by New You

We knew coffee lowered the risk of heart disease, inhibited different types of cancer, protected your liver, lowered your risk of type 2 diabetes, and made you live longer in general, but the results of a new study are quite astonishing.

Coffee, I'm naming it the healthiest drink in the world - but it’s nothing to do with Caffeine and more to do with CGA

Granted, coffees previous accomplishments were all praiseworthy, but when the American Journal of Clinical Nutrition reported that drinking coffee has been found to elevate testosterone while simultaneously lowering estrogen in both men and women, for me the argument was over.

What They Did

Epidemiologists from Harvard University looked at data from 15,551 women and 7,397 men who'd participated in the Nurses' Health Study and the Health Professionals Follow-Up study.
They wanted to know how drinking coffee affected C-peptide levels, estrone, total and free estradiol, total and free testosterone, total adipokinectin, high-molecular-weight adipokinectin, leptin, C-reactive protein, interleukin 6, and soluble tumor necrosis factor receptor 2, among other things.

What They Found

Compared with non-drinkers, subjects who drank four or more cups of coffee a day had lower concentrations of estrone (-6.4%), total estradiol (-5.7%), and free estradiol (-8.1%), while displaying higher levels of free testosterone (7.3% in women and 3.6% in men), and total testosterone (9.3% in women and 5.3% in men).

Levels of C-peptide, leptin, C-reactive protein, IL-6, and sTNFR-2 all went down too, while levels of the fat-burning hormome adipokinectin went up (9.3%).
The effects were dose dependent, meaning that while one daily cup of coffee had some beneficial effects, two cups worked better and three worked better still, while four or more cups showed maximum benefits. Perhaps surprisingly, it didn't seem to matter whether the participants were drinking caffeinated or decaffeinated coffee – the effects were largely similar.

The researchers concluded the following:

"Our data indicate that coffee consumption is associated with favorable profiles of numerous biomarkers in key metabolic and inflammatory pathways."

How to Use This Info

So what is it about coffee that makes it so damn healthy to drink? It definitely has nothing to do with caffeine, as this study and numerous others – including at least one that measured the ergogenic benefits of coffee – found that the advantages were conveyed equally well by decaf coffees.

Instead, it likely has something to do with the over 1,000 biologically active compounds found in the drink, but while many of them are highly anti-inflammatory and anti-oxidative, there's one that appears to be particularly gifted in those areas. It's known as chlorogenic acid, or CGA.

Therefore it makes sense that we should seek out brews that are particularly rich in CGA. Here's how to make sure you're getting the stuff that raises testosterone and lowers estrogen the most:

Opt for Kenyan, Ethiopian, or Colombian, because coffee beans grown at high altitudes and near the equator have the highest amount of CGA.
As far as general CGA guidelines are concerned, keep the following in mind.

Flavored blends don't usually have a high CGA content because they typically use low-quality, low CGA beans (the artificial flavor negates the need for good-tasting, high-CGA beans).

Light and medium roast coffees preserve CGA, while dark roasts destroy them (along with generating undesirable byproducts like acrylamide, the carcinogen found in French fries and potato chips).

Use fresh ground coffee beans when possible. Pre-ground versions usually lack flavor and are short on CGA

Very fine grinds are the most healthful, but also the most bitter. Medium grinds have an acceptable amount of CGA.

What Our Clients Say:

"Walking out of New You approx. 14 weeks later was easy. The whole world seemed different, I weighed 60lbs less, I was lighter on my feet having much more energy. Weighing 13 stone 5lbs with a 37.5 inch waist, felt great. Having lots more muscle tone, that felt even better. I am now significantly stronger tighter and fitter than ever before."

David Kiely

"After 12 weeks of 6am starts, constant attention from John, good pains and a well-balanced diet... I love what I have become. I couldn't believe that I fitted back into my leather trousers that I couldn't pull up above my knees. And boy do they fit well! I suppose losing 12 kg of body fat and over 8 inches from my waist whilst gaining nearly 2 kg of muscle had to make a difference. "


"Its nearly 11 months since I started with New You. I haven’t put any weight back on, in fact I have continued to get considerably leaner lighter stronger and fitter.* I weigh just over 13 stone, my body fat is now under 15% which makes me pretty athletic, my waist is down to 32 inches and my lean tissue has continued to improve."

Colin Duffy

"Walking through the doors of NEW YOU for the first time was extremely difficult. At 55-years of age I had very little confidence and low self esteem. Twelve weeks later I walked out of NEW YOU a completely different person. I had dropped 37lbs of body fat, which meant I had gone from just over 11 stone to 8 and a half stone."


"I would like to thank my trainer and the medical support from New You and all the team who took a keen interest in my results. Also a special thanks to my mother Christine who got me started and supported me all the way. I have to say that one of the life changing moments I have had besides everything else… is to be able to buy clothes off the peg."
