https://www.nestacertified.com/nutritionist/ A fad diet is an eating plan that becomes popular quickly. Fad diets often promise dramatic, unrealistic weight loss results. Many are designed to take advantage of people's willingness to "try anything" to lose weight look and feel better, and reduce their risk for weight-related health problems, such as diabetes, heart disease and other conditions.
It's difficult for most people to maintain any diet that drastically restricts their food choices or requires them to eat unusual foods, very little food, or the same foods day after day. Therefore, people who lose weight on a fad diet usually gain the weight back again.
