It's remarkable how often researchers draw false conclusions from accurate data. In this BBC News item we read that a study of "almost 400,000 adults found that eating meat was linked with weight gain, even in people taking in the same number of calories.
The strongest association was found with processed meat, such as sausages and ham, the Imperial College London team reported."
But instead of adopting the scientific approach and investigating why the processing of meat, such as sausages and ham, was so significant, they have decided that their research "counters the theory that diets with high amounts of protein and low amounts of carbohydrate promote weight loss." - What nonsense! What arrant nonsense! Research is a waste of time and expense when such an illogical conclusion is drawn! - They also failed to follow the clue about the calories to its logical conclusion.
I suggest that they investigate the significance of salt/sodium intake on weight gain. It's high time somebody did! (High sodium content is the main difference between processed meat and fresh meat.)How to lose excess weight safely and easily without bothering about calories at all.
