I periodically go low-carb to trim off a few pounds but also love them carbs...we eat a lot of meat but probably manage a 50-50 split in where the calories come from.
I used to log over 10,000 miles a year on my bicycles. In much younger days I was a State Champion and nationally ranked bicycle road racer. So I was interested in nutrition to enhance my performance from my early days.
But the nutritional needs of someone who is burning thousands of extra calories a day are far different and not really applicable to someone who lead a more sedentary lifestyle. Consuming carbohydrates are not only necessary to maintain the glycogen storage in an endurance athletes muscles but are also the most efficient source of fuel. The fad diet aficionados weed themselves out of the upper echelons of endurance sports. It just doesn't mix.
Unfortunately, having so many excess calories to burn and having to work to keep from losing large amounts of body mass, tends to cause people to develop habits that are not helpful when they get older and slow down. At one time I could eat two or three times what I do now and not gain an ounce. I could also eat pounds of greasy foods without spiking my cholesterol numbers.
Fortunately my wife is a retired nurse who taught diet, nutrition, and exercise classes for many years. Her former students used to approach her often when we were out and about and thank her for helping them to change their lives. She is a wealth of information and also helps to keep me on the straight and narrow despite my extreme love of homemade barbecue.
Firehouse meals while I was still working tended to be highly meat centric. And unfortunately many of my former coworkers went on Atkins style low carb diets. So I got to witness the devastation this type of diet philosophy has on people when it is applied over the long term. Strict adherents literally go to their graves while refusing to accept the dietary suggestions of their doctors. I have lost a number of friends to what can only be described as a combination of hubris, stubbornness and stupidity.
