Expert Opinions

Medical Expert

“The human body quite simply can’t cope with this deluge of sugar and processed foods; the consequences are all around us. Therefore, I endorse this book for two reasons. Firstly because it encourages us all to look at our dietary habits through new eyes and understand that the food we eat has a significant impact on our health and wellbeing. Not just what we eat but understanding the when and the why. Perhaps more importantly for me the second reason – the author Cian Foley. I have known Cian for many years and he has attended several events I have hosted on health and wellbeing. His ongoing personal transformation over that time from couch potato to kettle bell champion has been nothing short of inspirational.”

“I was always fit but I could never put on muscle, and if I did, I’d loose muscle getting rid of body fat, after doing the Don’t Eat for Winter diet I gained more muscle quicker than ever without starving myself and amazingly I’m even getting a six pack, and the best thing for me is I’m only on the plan two weeks…..”

“Just finished reading Don’t Eat for Winter (in 1 sitting) and all I can say is WOW !!! Cian Foley you have done an incredible job putting this piece of work together. My recommendation is, If you are in any way interested in getting a handle on your own health and body then do not let this book pass you by… The beauty of it is twofold I think. 1. You explain what is a pretty complicated human biological process in very simple terms without being condescending or “dumbing it down” and 2. The rules or guidelines are simple and flexible in terms of the foods which means anyone can follow along without too much effort.”

Author of Don't Eat for Winter. 2 time European, pan-American and World amateur kettlebell champion. who went from an obese 115kg to a fit and healthy 78kg through his 5 year journey of discovery around nutrition and exercise. I believe that we will see an avalanche of fat fall from the Earth as people escape from the infinite autumn through The DEFoW Diet concept.
