What You'll Learn

Potential health risks
The Scarsdale diet is a low-calorie, low-carbohydrate, high-protein diet. It is promoted as a way to lose weight quickly, with the promise of losing 20 pounds in just 14 days. The diet is based on a book by cardiologist Dr Herman Tarnower, called 'The Complete Scarsdale Medical Diet', published in the late 1970s.
The diet is very restrictive, limiting followers to 1,000 calories per day, which is well below the recommended intake for adults. The diet also prescribes a specific meal plan for a set period, with a high proportion of protein (43%) and low carbohydrates (34.5%).
While the Scarsdale diet may lead to rapid weight loss, there are several potential health risks associated with it:
- Nutritional deficiencies: The diet is criticized for its extreme restrictions and very low-calorie intake, which can lead to nutritional deficiencies. It restricts many healthy and nutritious foods, such as potatoes, beans, and lentils, and may not provide enough calories to sustain normal body functions.
- Unsustainability: The diet is not designed to instill healthy eating habits and is therefore unlikely to result in sustained weight loss. It is highly restrictive and difficult to adhere to long-term. Most people are unable to maintain the lost weight, and many regain the weight once they stop dieting.
- Health complications: The diet may increase the risk of heart disease due to its high-fat ratio. It may also raise LDL (bad) cholesterol levels due to higher saturated fat intake. The diet could also potentially affect gut health and lead to constipation, nausea, weakness, and bad breath due to ketosis.
- Difficulty exercising: The diet may make it difficult to exercise safely due to the very low-calorie intake.
- Irritability and lack of focus: Restricting calories to such a large extent can lead to irritability and trouble focusing.
- Not suitable for everyone: The Scarsdale diet is not recommended for everyone, especially those with conditions like diabetes and high blood pressure. It is also not suitable for pregnant or breastfeeding women, who require more calories to sustain themselves and their babies.
- Unbalanced diet: The diet is criticized for being unbalanced due to the high amount of meat consumed.
- Organ complications: The low-calorie intake can potentially lead to organ complications.
Overall, while the Scarsdale diet may lead to rapid weight loss in the short term, it is not a safe or sustainable option for long-term weight loss. It is important to consult a healthcare professional before starting any restrictive diet to ensure it is safe and appropriate for your individual needs.

Unrealistic weight loss promises
The Scarsdale diet was created by Dr. Herman Tarnower, a cardiologist and the founder of the Scarsdale Medical Center, in the late 1970s. It is a low-calorie, low-carbohydrate, high-protein dietary pattern that promises to help followers lose up to 20 pounds in just 14 days. The diet recommends that 43% of daily calories come from protein, 34.5% from carbohydrates, and 22.5% from fats. This is in contrast to the current recommendations from the Food and Nutrition Board, which suggest adults obtain 45 to 65% of their calories from carbohydrates, 20 to 35% from fat, and 10 to 35% from protein.
The diet is very restrictive, limiting followers to only 1,000 calories per day, which is well below the recommended calorie intake for any adult. This drastic decrease in calories will likely lead to weight loss, but it is essential to note that this type of rapid weight loss is often unhealthy and unsustainable. The Scarsdale diet has been criticized for its unrealistic weight loss promises and extreme restrictions.
The initial phase of the diet lasts for 14 days, during which snacks are banned, and followers are given a strict meal plan. After this, followers transition to the Keep Slim program, which is slightly more flexible but still highly restrictive. The diet is generally effective in the short term, but it is not a safe option beyond two weeks and it does not teach dieters how to prepare healthy meals for long-term weight management. Most people are unable to maintain the lost weight and often regain a significant amount.
The Scarsdale diet is nutritionally unbalanced due to the high amount of meat consumed and may increase the risk of heart disease. It can also lead to negative side effects such as constipation, nausea, weakness, and bad breath due to ketosis. Furthermore, it is unsafe for people with certain conditions, such as diabetes and high blood pressure.
While the Scarsdale diet may offer quick weight loss results, it is not a sustainable or healthy long-term solution. It is important to consult with a healthcare professional before starting any restrictive diet to ensure it is safe and appropriate for your individual needs.

Nutritional deficiencies
The Scarsdale diet is a low-calorie, low-carbohydrate, high-protein diet. It involves eating a specific meal plan for 7-14 days, limiting dieters to 1,000 calories per day. The diet recommends that 43% of daily calories come from protein, 34.5% from carbohydrates, and 22.5% from fats. The diet is designed to increase satiety and reduce calorie intake.
However, the Scarsdale diet has been criticised for its potential to cause nutritional deficiencies. The diet is very restrictive, with a long list of banned foods and snacks. It is unsustainable and likely to lead to weight regain once stopped. The diet is low in fibre, and restricts many healthy, nutritious foods such as potatoes, beans, and lentils. As a result, it may not provide the body with enough calories and essential nutrients to sustain normal body function, and may lead to negative side effects such as constipation, nausea, weakness, and bad breath.
The Scarsdale diet is not nutritionally balanced, and is high in fat. This may increase the risk of heart disease and raise LDL (bad) cholesterol levels. The diet may also affect gut health and cause ketosis, a state where the body burns fat for energy.
The Scarsdale diet is not suitable for everyone, and those with conditions such as diabetes and high blood pressure should consult a doctor before starting the diet. It is important to get advice from a healthcare provider or registered dietician before starting any low-calorie diet to ensure that nutritional needs are met and that it is safe for the individual.

Weight regain after stopping
The Scarsdale diet is a 14-day, low-calorie, low-carb, high-protein diet that claims to help people lose weight. It recommends that 43% of your daily calories come from protein, with a total intake of 1,000 calories per day. While this approach is effective in the short term, long-term studies show no significant advantage over other diets for sustained weight loss.
The Scarsdale diet is prone to weight cycling, also known as yo-yo dieting. This pattern involves a constant cycle of quick weight loss followed by weight regain. The diet's initial phase is extremely restrictive, banning almost all snacks. After the first 14 days, you transition to the Keep Slim maintenance program, which is slightly more flexible. However, even with this program, few foods are allowed, and calories are still restricted. This makes it challenging to sustain the diet long-term.
Most people who follow the Scarsdale diet will likely lose weight during the first two weeks due to the drastic decrease in calories. However, once the diet is discontinued, it is highly likely that any weight lost will be regained. This is because very low-calorie diets paired with extreme food restrictions are unsustainable and often lead to weight regain once the diet is stopped. The rapid weight loss promoted by the Scarsdale diet is generally considered unhealthy and unsustainable by medical experts.
Instead of focusing on short-term, restrictive diets like the Scarsdale diet, it is recommended to adopt healthy lifestyle habits for long-term weight management. This includes practices such as portion control, healthy cooking techniques, regular exercise, and stress management. These habits promote sustainable weight loss and improve overall health, reducing the risk of potential health issues associated with extreme diets.

Lack of long-term studies
The Scarsdale diet is a low-calorie, low-carbohydrate, high-protein diet. It is based on a book called 'The Complete Scarsdale Medical Diet', written by cardiologist Dr Herman Tarnower and published in the late 1970s. The diet promises to help followers lose up to 20 pounds in just 14 days.
The diet is very restrictive, limiting followers to 1,000 calories per day. This is well below the recommended calorie intake for adults, which is 2,000–3,000 calories for men and 1,600–2,400 for women. The diet recommends that 43% of daily calories come from protein, 34.5% from carbohydrates, and 22.5% from fats.
There is a lack of long-term studies on the effectiveness and safety of the Scarsdale diet. While it can be effective in the short term, there is no evidence that it is beneficial for sustained weight loss. In fact, very low-calorie diets paired with extreme food restrictions are often unsustainable and lead to weight regain once the diet is stopped. The diet is also criticised for being nutritionally unbalanced, with high amounts of meat and saturated fat, which may increase the risk of heart disease.
The Scarsdale diet is not recommended for everyone. It is especially unsafe for people with conditions like diabetes and high blood pressure. It is important to consult a healthcare professional before starting any new diet, especially one that is very low in calories.
