Keto Weight Loss: Can Mem Lose It?

The ketogenic, or keto, diet is a high-fat, low-carb, moderate-protein food plan that aims to put the body into a metabolic state called 'ketosis'. The keto diet is similar to the Atkins diet in that it forces the body to use a different type of fuel. Instead of providing the body with glucose from carbohydrates, the keto diet relies on the liver to break down stored fat into molecules called ketones. While the keto diet has been hailed as a successful weight-loss strategy for men, its effectiveness for women is less clear.

Keto diet: What to eat and what to avoid

The keto diet is a high-fat, low-carb, moderate-protein food plan that aims to put your body into a metabolic state called 'ketosis'. This diet is similar to the Atkins diet in terms of how it works.

What to Eat

• Meat: steak, chicken, turkey, pork
• Fish: salmon, tuna, mackerel
• Eggs: cooked any way you like
• Vegetables: low-carb options such as green veggies, tomatoes, onions, etc.
• Avocados: a great source of healthy fats
• Berries: low in carbohydrates
• Healthy oils: extra virgin, coconut and avocado oil
• Nuts and seeds: almonds, walnuts, flax seeds, pumpkin seeds, chia seeds, etc.
• Cheese: cheddar, goat, cream, blue and mozzarella
• Butter and cream: especially grass-fed

What to Avoid

• Fruit: except for avocados and berries
• Alcohol: the carb content will throw you out of ketosis
• Foods and drinks high in sugar: cakes, sweets, cookies, brownies, and fizzy drinks
• Beans or legumes: peas, kidney beans, lentils, chickpeas, etc.
• Grains or starches: wheat-based products like rice, pasta, cereal, bread, etc.

The keto diet is based on the principle of depleting the body of carbohydrates, its primary source of energy, and forcing it to burn fat for fuel, thereby maximising weight loss. When you consume foods that contain carbohydrates, the body converts those carbohydrates into glucose, or blood sugar, which it then uses for energy. By reducing the intake of carbohydrates, the body must break down fat for energy. This process is called ketogenesis, and it produces ketones, which are used to fuel the body in the absence of glucose.

The keto diet plan requires fat to comprise roughly 60 to 80 per cent of your total calories. Protein makes up around 10 to 15 per cent, and the remaining 5-10 per cent (more or less) comes from carbs. Generally speaking, you won't eat more than 25 grams of carbs each day.

Keto diet and athletic performance

The ketogenic diet is a high-fat, low-carbohydrate diet that can help the body burn fat for fuel. While it has been shown to be effective for weight loss, its impact on athletic performance is less clear. Some athletes claim that the keto diet enhances their performance, while others argue that it hurts their performance.

There is some evidence to suggest that the keto diet may improve athletic performance in endurance athletes, such as marathon runners and long-distance cyclists. By depleting the body's carbohydrate stores, the keto diet forces the body to burn fat for fuel, which can increase fat oxidation and improve endurance. Additionally, the keto diet may reduce inflammation, which is beneficial for athletes as prolonged and vigorous exercise can trigger an inflammatory response.

However, the keto diet may not be ideal for athletes involved in high-intensity, short-duration sports. Research suggests that athletes in sports such as soccer, basketball, and sprinting may experience a drop in performance while on a ketogenic diet. This is because high-intensity exercises rely primarily on carbohydrates as a fuel source, and the keto diet restricts carbohydrate intake. As a result, athletes on a keto diet may notice increased exertion and heart rate and decreased power during these types of exercises.

Furthermore, the keto diet may not be the best choice for athletes looking to gain muscle mass, as it is moderate, not high, in protein, which is essential for muscle building. The keto diet can also be challenging for athletes who need to consume a certain number of calories to support their physical activity. The diet's appetite-suppressing effects may lead to an energy deficit, hindering recovery and progress.

Overall, the keto diet's impact on athletic performance is mixed. While it may benefit endurance athletes, it may hurt the performance of athletes in high-intensity, short-duration sports. Athletes considering the keto diet should carefully weigh the potential benefits and drawbacks and consult with a sports dietitian to ensure their nutritional needs are met.

Keto diet and diabetes

The ketogenic (keto) diet is a high-fat, low-carbohydrate diet that can be beneficial for people with diabetes, particularly those with type 2 diabetes (T2D). The keto diet can help manage blood glucose levels and reduce the need for insulin. However, it is important to note that the keto diet is not suitable for everyone and should be approached with caution, especially for those with type 1 diabetes (T1D).

The keto diet is based on the principle of depleting the body of carbohydrates, which are the body's primary source of energy. By restricting carbohydrate intake, the body is forced to break down fat for energy, a process called ketogenesis. This results in the production of ketones, which are used as fuel instead of glucose.

Benefits of the Keto Diet for Diabetes

The keto diet has been found to offer several benefits for people with diabetes:

• Improved blood glucose control: A review of studies found that keto diets can lower blood sugar levels and reduce the need for medication in people with T2D.
• Weight loss: The keto diet can aid in weight loss, which is beneficial for people with diabetes.
• Appetite suppression: The keto diet may help reduce feelings of hunger, which can be advantageous for weight management.
• Improved athletic performance: The keto diet has been found to improve endurance and recovery times in athletes.

Potential Drawbacks and Risks

While the keto diet offers potential benefits, there are also some drawbacks and risks to consider:

• Keto flu: Some people may experience side effects such as headaches, fatigue, and gastrointestinal issues when starting the keto diet.
• Nutrient deficiencies: The keto diet may lead to deficiencies in calcium, vitamin D, magnesium, and folic acid if not carefully planned.
• Heart health concerns: The high-fat content of the keto diet, especially saturated fat, can negatively impact heart health and increase the risk of cardiovascular disease.
• Low blood sugar (hypoglycemia): Restricting carbohydrates too much can cause a rapid drop in blood sugar levels, especially for those taking medications that increase insulin levels.
• Challenges with long-term adherence: The restrictive nature of the keto diet can make it challenging to stick to in the long term.

Recommendations and Precautions

When considering the keto diet for diabetes management, it is essential to consult with a healthcare professional, especially for those with T1D. The keto diet may not be suitable for everyone, and individual factors such as cultural, ethnic, social, and economic considerations should be taken into account. Additionally, close monitoring of blood glucose and ketone levels is necessary to ensure the diet is not causing negative effects.

Alternative Dietary Approaches

Other dietary approaches, such as the Mediterranean diet, have also been found to be effective in managing blood glucose levels in people with diabetes. The Mediterranean diet emphasizes whole grains, fish, vegetables, legumes, fruits, and healthy fats, and is generally considered easier to follow than the keto diet.

Keto diet and heart health

The keto diet is a popular, low-carb, high-fat diet that has been touted as a quick way to lose substantial weight. However, its impact on heart health is a cause for concern.

The keto diet is based on the principle of achieving ketosis, a metabolic state where the body burns fat as an alternative source of energy instead of carbohydrates. Typically, carbohydrates are the body's primary energy source, which are converted into glucose (blood sugar) and absorbed into the bloodstream. By depleting the body of carbohydrates, the keto diet forces the body to break down fat for fuel, leading to weight loss.

Risks to heart health

The keto diet's high intake of animal-based products and saturated fats is linked to an increased risk of cardiovascular issues, including atherosclerosis and cardiovascular diseases. Research suggests that while the keto diet can quickly lower triglycerides, blood pressure, and body weight, its long-term benefits for heart health are unclear.

One review found that the keto diet was associated with higher total and low-density lipoprotein (LDL) cholesterol levels than diets with 45% to 65% carbohydrates. High cholesterol levels are a risk factor for heart disease, so this increase could be detrimental to heart health.

Additionally, the keto diet's restriction of whole grains, legumes, and fruits can result in a loss of dietary fiber, which is important for protecting the heart.

Precautions and recommendations

Due to the potential risks to heart health, it is recommended that individuals with risk factors for heart disease, such as elevated cholesterol, high blood pressure, or a strong family history of the disease, consult a healthcare provider before starting the keto diet.

It is also important to note that not all sources of fat are equal. While on the keto diet, it is crucial to focus on consuming healthy fats, such as extra virgin olive oil, avocado, salmon (for omega-3 fatty acids), nuts, and nut butters. These sources of fat are better for cardiovascular health than processed or animal-based fats.

Furthermore, including a steady intake of green vegetables such as broccoli, celery, kale, and spinach is recommended, as a 2010 study found that low-carb dieters who focused on vegetable-based sources of fat and protein had a 23% lower risk of heart disease than those who relied more heavily on meat.

While the keto diet may lead to weight loss and improved cardiovascular risk factors in the short term, its long-term effects on heart health are less clear. The high intake of saturated fats and the restriction of dietary fiber may increase the risk of cardiovascular issues. Therefore, it is essential to consult a healthcare professional before starting the keto diet, especially for those with risk factors for heart disease.

Keto diet and weight loss

The keto diet is a high-fat, low-carb, and moderate-protein food plan that aims to put your body into a metabolic state called 'ketosis'. The diet was initially developed in 1924 by Dr Russell Wilder as a treatment for epilepsy, but it has since been used for weight loss and the management of other health conditions.

The keto diet is based on the principle of depleting the body of carbohydrates, its primary source of energy, and forcing it to burn fat for fuel. This process is called ketogenesis, and it involves the liver breaking down stored fat into molecules called ketones. To reach a state of ketosis, most people need to limit their daily carbohydrate intake to fewer than 50 grams, although this can vary depending on body size.

Weight Loss Benefits of the Keto Diet

The keto diet has been associated with weight loss, although the evidence for its superiority over other diets is mixed. Some research suggests that the keto diet can lead to faster weight loss compared to a calorie-reduction diet. This may be due to the satiating effect of the high-fat content, decreased food cravings, and reduced appetite-stimulating hormones. Additionally, the keto diet may suppress appetite, although the reason for this is not yet fully understood.

Drawbacks of the Keto Diet

The keto diet can be challenging to stick to in the long term due to its restrictive nature. It may also lead to "keto flu," which includes symptoms such as headaches, fatigue, dizziness, and gastrointestinal issues. The diet's high-fat content, especially saturated fat, can also raise cholesterol levels and increase the risk of developing heart disease.

Who Should Avoid the Keto Diet?

While the keto diet can be effective for weight loss in some individuals, it may not be suitable for everyone. Those at risk for heart disease, pregnant or breastfeeding women, individuals with kidney disease, and anyone with a history of eating disorders should approach the keto diet with caution. Additionally, the keto diet may not be as effective for weight loss in women due to the potential interference of estrogen in the weight loss process.

The keto diet has been shown to aid in weight loss, particularly in men. However, it is important to consult with a healthcare professional before starting any new diet, as there may be risks involved. The keto diet is restrictive and can be challenging to maintain, and it may not be suitable for everyone.
