Keto Diet: High Calorie Or Healthy?

The keto diet is a high-fat, low-carb approach to eating, designed to induce ketosis, where the body burns fat for fuel. This can lead to weight loss and enhanced energy. While the keto diet is often associated with weight loss, it can also be used to gain weight. This is because fat contains more than double the number of calories per gram than carbohydrates.

A high-calorie keto diet consists of a daily calorie intake of around 3500 calories, with 70-85% of calories from fat sources, 15-20% from protein sources, and 5-10% from carbohydrates.

Some high-calorie keto foods include ribeye steak, chicken thighs, eggs, fatty fish, cooking oils, and nut butters.

High-calorie keto foods for weight gain

While the keto diet is often associated with weight loss, it can also be used to gain weight in a healthy way. The key is to focus on high-calorie, nutrient-dense foods within the ketogenic framework. This means eating meals rich in healthy fats, with moderate protein, and minimal carbs to increase your overall caloric intake. Here are some high-calorie keto foods that can help you gain weight:

• Ribeye steak is the fattiest cut of beef, making it a great option for weight gain on the keto diet. It is also a good source of protein, which can help you build muscle.
• Ground beef is a more affordable option that is still high in fat and calories. Look for 80% lean ground beef for the best results.
• Fatty fish, such as salmon, mackerel, sardines, and trout, are excellent sources of omega-3 fatty acids and protein. They are also calorie-dense, making them a perfect addition to your keto diet.
• Nut butters, including almond butter, peanut butter, and pecan butter, are high in healthy fats, fibre, and various vitamins and minerals. They are a great way to add extra calories to your diet.
• Full-fat Greek yogurt provides both fat and protein, as well as probiotics for improved digestion. Just be sure to choose a brand without added sugar to keep the carb count low.
• Cheese is a versatile food that is high in both fat and protein. It can be added to many dishes or enjoyed as a snack, making it easy to increase your calorie intake.
• Avocados are high in healthy fats, fibre, antioxidants, and various vitamins and minerals. They can be added to smoothies, salads, eggs, or used as a replacement for butter or margarine.
• Dark chocolate (70% or higher) is a good source of antioxidants and can be enjoyed as a sweet treat on the keto diet.
• Cooking oils, such as olive oil, avocado oil, and coconut oil, are essential for cooking and can help you increase your fat and calorie intake.
• Chicken thighs are a fattier and juicier option than chicken breasts, and they are more economical than steak. They are a great source of protein and fat on the keto diet.
• Eggs are a keto-friendly powerhouse, providing high-quality protein and healthy fats. To increase the fat content, cook them in oil, butter, or ghee.

Remember, when trying to gain weight on the keto diet, it is important to maintain a caloric surplus. You may also want to incorporate weight lifting to help build muscle and increase your weight. Consult with a healthcare professional or registered dietitian to ensure that the keto diet is right for you and to get personalized advice.

Calorie surplus and macronutrient breakdown

To gain weight, you need to be in a calorie surplus, meaning you need to consume more calories than you burn. This is true whether you are on a keto diet or not. However, achieving a calorie surplus on a keto diet can be challenging due to the restrictive nature of the diet and the tendency for keto-friendly foods to be high in fat and calories.

Macronutrient Breakdown

When following a keto diet, it is important to monitor your macronutrient intake to ensure you are getting the right balance of nutrients and maintaining ketosis. Here is a breakdown of each macronutrient and its role in a keto diet:

Fat

Fat is the primary energy source on a keto diet. It is crucial to consume enough fat to provide your body with the energy it needs. Each gram of fat contains nine calories, making it the most calorie-dense macronutrient. When choosing fats, prioritise unsaturated fats such as omega-3s found in salmon and walnuts. Avocado, seeds, olives, cooking oils, and eggs are also excellent sources of healthy fats.

Protein

Protein is essential for muscle growth and repair. On a keto diet, it is recommended to consume between 15-20% of your calories from protein sources. Keto-friendly protein options include plant and animal products like nuts, oils, eggs, fish, meat, and dairy. However, it is important not to overdo your protein intake as it can impact ketosis.

Carbohydrates

Carbohydrates are restricted on a keto diet, typically limited to 5-10% of your total calorie intake. This means that cereals, bread, grains, starchy vegetables, and most fruits are limited. Instead, focus on low-carb vegetables like leafy greens, peppers, broccoli, cauliflower, and asparagus.

Calorie Requirements

The number of calories you need to consume to be in a surplus will vary depending on your individual goals, activity levels, and metabolism. As a general rule, it takes an extra 3,500 calories per week to gain one pound of weight. This equates to consuming 500-1,000 extra calories per day. However, it is important to note that this may vary depending on how your body responds to the keto diet. Some people may need to further restrict carbohydrates or increase their fat intake to achieve the desired results.

Sample Meal Plan

• Breakfast: Eggs, Cheese, and Radishes
• Lunch: Tuna and Avocado Salad
• Snack: Protein-boosted Yogurt
• Dinner: Bacon Wrapped Guacamole Stuffed Chicken
• Side: Raw Cauliflower Tabouli

Remember, the key to achieving a calorie surplus on a keto diet is to focus on consuming enough healthy fats while also ensuring adequate protein and carbohydrate intake. It is important to work with a healthcare professional or dietitian to determine the right calorie and macronutrient targets for your specific needs and goals.

Ketogenic diets and weight loss

The ketogenic diet is a high-fat, low-carb diet that has been shown to be effective for weight loss. It involves reducing carbohydrate intake and replacing it with fat, which puts the body into a metabolic state called ketosis. In ketosis, the body becomes efficient at burning fat for energy and turns fat into ketones in the liver, which can supply energy to the brain.

Weight Loss Effects

Ketogenic diets can help with weight loss by:

• Increasing protein intake, which has many weight loss benefits.
• Gluconeogenesis - converting fat and protein into carbs for fuel, which may burn additional calories.
• Suppressing appetite - ketogenic diets help you feel full by changing hunger hormones like leptin and ghrelin.
• Improving insulin sensitivity - ketogenic diets can improve fuel utilization and metabolism.
• Decreasing fat storage - ketogenic diets may reduce lipogenesis, the process of converting sugar into fat.
• Increasing fat burning - ketogenic diets may slightly increase the amount of fat burned during rest, daily activity, and exercise.

Sample Ketogenic Diet Plan

• Breakfast: Veggie and egg muffins with tomatoes.
• Lunch: Chicken salad with olive oil, feta cheese, olives, and a side salad.
• Dinner: Salmon with asparagus cooked in butter.
• Breakfast: Egg, tomato, basil, and spinach omelet.
• Lunch: Almond milk, peanut butter, spinach, cocoa powder, and stevia milkshake with a side of sliced strawberries.
• Dinner: Cheese-shell tacos with salsa.
• Breakfast: Nut milk chia pudding topped with coconut and blackberries.
• Lunch: Avocado shrimp salad.
• Dinner: Pork chops with Parmesan cheese, broccoli, and salad.

Tips for Sticking to the Diet

Some tips for sticking to a ketogenic diet include:

• Familiarize yourself with food labels and check the grams of fat, carbs, and fiber to determine how foods fit into your diet.
• Plan your meals in advance to save time.
• Look for keto-friendly recipes and meal ideas online or in cookbooks.
• Consider using a meal delivery service that offers keto-friendly options.
• Bring your own food when visiting family and friends or eating out.

Potential Side Effects and Risks

The ketogenic diet is generally safe, but there may be some initial side effects, such as diarrhea, constipation, vomiting, poor energy and mental function, and decreased exercise performance. Long-term risks may include low protein in the blood, extra fat in the liver, and micronutrient deficiencies. It is important to consult a doctor before starting a ketogenic diet to ensure it is safe and suitable for you.

The metabolic advantage of ketogenic diets

The ketogenic diet is a high-fat, low-carbohydrate diet that aims to facilitate weight loss, enhance mental clarity, and boost energy levels. By reducing carbohydrate consumption and increasing fat and protein intake, this diet induces a metabolic state called ketosis, where the body utilises fat as its primary fuel source instead of carbohydrates.

Ketosis

When the body is in a state of ketosis, it shifts from using carbohydrates as its main source of energy to using fat. This shift occurs because the body's primary energy source, glucose, is no longer readily available due to the restricted carbohydrate intake. As a result, the body breaks down fat into ketones, which can be used as an alternative energy source.

Benefits of ketosis

Ketosis has several benefits, including:

• Increased energy production: Ketone bodies produce more ATP (adenosine triphosphate), which is the body's energy source, than glucose. This means the body can maintain efficient fuel production even when experiencing a caloric deficit.
• Reduced free radical damage: Ketone bodies can reduce free radical damage and enhance the body's antioxidant capacity.
• Alternative energy source for vital organs: Ketone bodies can be used as an energy source by the brain, heart, kidneys, and muscle tissue.

Types of ketogenic diets

There are four main types of ketogenic diets:

• Classic long-chain triglyceride (LCT) ketogenic diet: This is the most traditional type, with a fat intake of around 90%, protein intake of 6%, and carbohydrates making up the remaining 4%.
• Medium-chain triglyceride (MCT) ketogenic diet: This diet includes more medium-chain triglycerides, which are more ketogenic than long-chain triglycerides. It is more flexible in terms of diet ratios and is often used by those who find the LCT diet unpalatable.
• Modified Atkins diet (MAD): This diet is based on the Atkins diet, which is popular for weight loss. It includes less strict intake of fat (65%), protein (30%), and carbohydrates (5%).
• Low glycemic index treatment: This diet focuses on stabilising blood glucose levels by consuming low-glycemic index foods, which have a minimal impact on blood sugar levels.

Impact on metabolism

The ketogenic diet has a significant impact on metabolism, particularly by reducing carbohydrate intake and increasing fat consumption. This leads to decreased insulin levels, improved insulin sensitivity, and enhanced fat catabolism. As a result, blood lipids, including cholesterol and triglycerides, can be lowered, reducing the risk of cardiovascular disease.

Weight loss

The ketogenic diet is often used for weight loss, and several studies have shown its effectiveness in this area. The diet can lead to rapid weight loss, with individuals often losing up to 10 pounds in 2 weeks or less. This is due to the diuretic effect of the diet, followed by fat loss. Additionally, ketosis can decrease hunger, further aiding in weight loss.

Other health benefits

The ketogenic diet has been found to have potential benefits for various health conditions, including:

• Heart disease: The diet can improve risk factors such as body fat, HDL cholesterol levels, blood pressure, and blood sugar.
• Cancer: The diet may slow tumour growth by limiting the glucose available to cancer cells and reducing inflammation.
• Alzheimer's disease: The ketogenic diet may reduce symptoms and slow the progression of Alzheimer's disease by improving brain metabolism and reducing oxidative stress.
• Epilepsy: The diet has been shown to reduce seizures in epileptic children.
• Parkinson's disease: The ketogenic diet has been found to improve symptoms of Parkinson's disease, particularly non-motor symptoms.
• Polycystic ovary syndrome: The diet can help regulate insulin levels, which may play a role in polycystic ovary syndrome.

Potential risks and side effects

While the ketogenic diet has many potential benefits, there are also some risks and side effects to consider. These include:

• Micronutrient deficiencies: The restrictive nature of the diet can lead to inadequate intake of essential vitamins, minerals, and phytochemicals.
• Digestive issues: The high-fat, low-fiber nature of the diet can cause constipation, diarrhea, and bloating.
• Kidney stones: The high-fat, low-carbohydrate nature of the diet can increase the risk of developing kidney stones.
• Heart disease: The diet's high saturated fat content and lack of fiber may increase the risk of heart disease.
• Muscle loss: Rapid weight loss on the ketogenic diet can lead to muscle loss, negatively impacting athletic performance.

The ketogenic diet has been shown to have metabolic advantages, particularly in weight loss and the management of various health conditions. However, it is important to note that the diet may not be suitable for everyone, and there are potential risks and side effects. It is always recommended to consult with a healthcare professional before starting any new diet.

Appetite suppression

The ketogenic diet is a popular eating plan that involves a severe restriction of carbohydrates, with an emphasis on consuming high amounts of fat and moderate amounts of protein. While the diet is often associated with weight loss, it can also be used to gain weight by eating calorie-dense foods. One of the key features of the ketogenic diet is its potential to suppress appetite, which has been observed in several studies.

Ketogenic diets are known to induce a state of ketosis, where the body shifts from using glucose as its primary energy source to burning fat for fuel. This metabolic shift is believed to play a crucial role in suppressing appetite. Clinical trials have shown that individuals adhering to ketogenic diets experience reduced hunger and a decreased desire to eat, even in the context of weight loss and energy restriction. This appetite suppression may be due to the body's ability to adapt to using fat as an alternative fuel source, reducing the reliance on glucose from carbohydrates.

Hormonal Changes and Appetite

The ketogenic diet has been found to influence the secretion of certain hormones that regulate appetite. Specifically, it prevents an increase in ghrelin, a hormone that stimulates hunger, which typically occurs with weight loss. Additionally, the diet has been shown to reduce hunger and increase feelings of fullness or satiety. However, the exact threshold of ketosis required to induce appetite suppression is still unknown, and further research is needed to fully understand the underlying mechanisms.

Timeline of Appetite Changes

A study by Nymo et al. (2017) investigated the timeline of changes in appetite during weight loss with a ketogenic diet. They found that while there was an initial increase in fasting hunger and desire to eat within the first 3 weeks of the diet, these feelings subsided after that point. Interestingly, a weight loss of 10-17% while in ketosis was not associated with increased appetite. However, once participants reintroduced food after the diet, hunger feelings and ghrelin concentrations increased significantly.

Exogenous Ketones and Appetite

In addition to dietary interventions, the use of exogenous ketones, such as ketone esters, has been explored as a potential appetite suppressant. Acute consumption of a ketone ester drink has been shown to reduce feelings of hunger and increase satiety compared to a dextrose drink. This provides an alternative option for individuals who may not be able to adhere to the restrictive nature of ketogenic diets but still want to experience the potential benefits of ketosis.
