Anacioco cited Cleveland Clinic’s definition of fad diet as "eating plans that are often promoted as the best or fastest approach to losing weight." The most popular fad diets worldwide include Atkins diet, Ketogenic diet, detox diet, vegan diet, Paleolithic diet, Human Chorionic Gonadotropin (HCG) diet, and intermittent fasting.
Fad diets are still rampant because people are after quick results, market campaigns are powerful through testimonies, and due to social media influence, she said.
“One way to spot a fad diet is if it promotes short term changes like it promises effect of losing weight of one kilogram in five days, which sounds too good to be true,” she explained.
Anacioco stressed that the National Nutrition Council (NNC), as well as other nutritionists and dietitians, do not promote the practice of fad diets due to their effects on the body.
“Fad diets are nutritionally inadequate it can lead to the occurrence of malnutrition due to certain mineral or vitamin deficiencies. It can also lead to dehydration because of missing food groups, absence of physical activity, rapid weight loss. It has inconsistent scientific evidence and detrimental to those with chronic diseases,” she pointed out.
Instead, they recommend adherence to a holistic, sustainable, adequate, and nutritionally balanced diet, complemented by an active lifestyle and lifelong behavioral modifications.
