BREAKING MEDICAL NEWS: Study Claims ‘Paleo’ Diet Leads to Worsening Cholesterol


A breaking medical study has just been published, arguing that the “Paleo” diet worsens cholesterol levels.

The Paleo Diet is also referred to as the Paleolithic Diet, the Paleodiet, the Caveman Diet, the Stone Age Diet, and the Hunter-Gatherer Diet.

The diet consists mainly of meat, poultry, shellfish, fish, and eggs, as well as non-starchy orange, green, and yellow vegetables, fruits and nuts.

Grains, legumes, and potatoes are all off-limits. This diet is based on the belief that during the Paleolithic era – approximately ranging from 10,000 to 2.5 million years ago – saw hominids eating primarily animal foods.

The new study, “Unrestricted Paleolithic diet is associated with unfavorable changes to blood lipids in healthy subjects”, was published in the International Journal of Exercise Science.

Researchers conducted the study by placing 44 healthy adults on a “Paleo” diet comprised of lean meat, fish, eggs, nuts, fruit, and vegetables, as well placing them on a circuit training program.

But after ten weeks, the study’s authors claim, the LDL (“bad”) cholesterol increased by 12.5 mg/dL and total cholesterol by 10.1 mg/dL. Beyond that, triglycerides also increased slightly. The most intriguing aspect of the study was the finding that the worst outcomes were seen among those who had been the healthiest before starting the diet.

Further, The Physicians Committee For Responsible Medicine noted that the study’s authors concluded that any improvements from the exercise program may be negated by the “Paleo” diet.

    Why are no recent articles citing their references?

    LDL levels are a poor indicator of heart disease. A better indicator is HDL to Triglyceride ratio, which shows whether the LDL is large and healthy or very small and atherosclerotic.
