The keto diet is a high-fat, low-carbohydrate diet that aims to transition the body's metabolism into a state called ketosis, where fat becomes the primary source of energy instead of carbohydrates. To achieve ketosis, it's important to limit your intake of high-carb foods like pasta, potatoes, rice, bread, fruits, and other starchy foods. Instead, you can eat high-fat foods like red meats, fatty fish, nuts, cheese, butter, olive oil, and avocados. The keto diet has gained popularity due to its potential benefits for weight loss, blood sugar management, and preventing cancers and neurodegenerative conditions. However, it may not be suitable for everyone, and there are potential negative effects on heart health and kidney health. It is always recommended to consult with a doctor or dietitian before starting any new diet.

What You'll Learn
Eat fatty fish, cheese, and non-starchy vegetables
The keto diet is a low-carb, high-fat, and moderate-protein diet. The diet aims to put the body into a state of ketosis, where the body burns fat for energy instead of carbohydrates. This process can lead to weight loss.
Fatty fish are an excellent source of healthy fats and protein, making them a great option for keto dieters. Some fatty fish that are suitable for the keto diet include Atlantic mackerel, sardines, anchovies, and Arctic Char. These fish are also loaded with vitamins and minerals, such as vitamin D, omega-3 fatty acids, vitamin B, selenium, and copper.
Cheese is another food that is generally considered keto-friendly, as it is high in fat and low in carbs. Goat cheese, in particular, is a good option as it contains zero carbs and is easier to digest than cow's milk cheese. Other cheeses that are suitable for the keto diet include blue cheese and full-fat, high-quality, grass-fed cheeses. However, it is important to note that some people may find that they lose weight faster and feel better when they remove dairy from their keto diet. Additionally, highly processed cheeses, such as spray cheese and American cheese, are best avoided as they do not offer much nutritional benefit.
Non-starchy vegetables are also a good option for keto dieters, as they are typically low in carbs. Some examples of keto-friendly vegetables include celery, tomatoes, spinach, mushrooms, cucumber, zucchini, and asparagus. These vegetables can be prepared in a variety of ways and can be used in salads, sandwiches, or as a low-carb alternative to pasta. While it is important to limit high-carb vegetables on the keto diet, it is also crucial to ensure adequate nutrient intake to reduce the risk of nutrient deficiencies associated with the diet.

Avoid glazed ham, fruit, and starches
The keto diet is a low-carb, high-fat diet often used to promote weight loss. On a keto diet, it is important to avoid glazed ham, certain fruits, and starches.
Firstly, while ham itself is not off-limits on a keto diet, traditional glazed hams are typically made with sugar-laden ingredients such as sugar, syrup, or jam, which are high in carbohydrates and thus not keto-friendly. However, there are ways to make a sugar-free glaze for ham using sugar substitutes, keto-friendly maple syrup, or vinegar and spices to add flavor without the carbs.
Secondly, while fruit is a healthy and nutrient-rich food group, some fruits are high in carbohydrates and should be avoided or limited on a keto diet. Fruits such as plums and prunes are very high in carbs, with 64 grams of carbs per 100-gram serving. Fruit smoothies and juices, except for lemon and lime, should also be avoided due to their high carb content. However, some low-carb fruits such as watermelon, berries, avocado, cantaloupe, olives, and tomatoes can be included in a keto diet in moderation.
Finally, while starches are typically avoided on a keto diet due to their carbohydrate content, resistant starch is an exception. Resistant starch is a unique form of starch that resists digestion and feeds the beneficial bacteria in the gut microbiome. It has a low level of net carbs and can be found in certain easy-to-find foods, making it a keto-friendly option.
In summary, when following a keto diet, it is important to avoid glazed ham made with sugar, as well as high-carb fruits and starches. However, there are ways to modify recipes to make them keto-friendly, and some low-carb options can be included in moderation.

Nuts and seeds are good sources of healthy fats and protein
The keto diet is a low-carb, high-fat diet often used to promote weight loss. Carbohydrates are the body's preferred source of energy, but on a strict ketogenic diet, about 5% to 10% of energy intake is from carbohydrates. The reduction of carbohydrates puts the body into a metabolic state called ketosis, where the body starts breaking down stored fat into molecules called ketone bodies to use for energy.
The Australian Dietary Guidelines recommend a nut intake of 30 grams on most days of the week as part of a healthy diet for adults. Nuts and seeds are also good for regulating body weight as their fats are not fully absorbed, and they regulate food intake. They are high in 'good fats' such as monounsaturated fats (most nut types) and polyunsaturated fats (mainly walnuts), and low in saturated fats. This combination of 'good fats' makes nuts heart-healthy, as they help to reduce low-density lipoprotein (LDL) cholesterol, also known as 'bad' cholesterol. Nuts and seeds also help to maintain healthy blood vessels and blood pressure, partly through their arginine content, and reduce inflammation in the body as they are high in antioxidants.
Some nuts are higher in carbs than others, so it's important to watch your intake. Cashews, for example, are much higher in carbs than pecans or macadamia nuts. It's recommended to start with just a few or up to 1/4 cup (about 25 grams) for a snack.

Avoid trans fats and partially hydrogenated oils
The keto diet is a low-carb, high-fat diet that promotes weight loss. It is designed to shift the body's metabolism into a state called ketosis, where fat becomes the primary source of energy instead of carbohydrates. While there is no direct link between trans fats and ketosis, partially hydrogenated oils, which often contain trans fats, can negatively impact heart health and contribute to inflammation.
To maintain optimal health while on a keto diet, it is best to avoid trans fats and partially hydrogenated oils. These oils are often found in margarine and processed foods. Instead, opt for natural sources of healthy fats like avocados, olive oil, coconut oil, and nuts. These alternatives promote ketosis and enhance overall wellness.
Processed foods, such as chips, pre-packaged snacks, and convenience meals, can appear low in carbs but often contain hidden sugars and starches. These covert sources of carbohydrates can impede your keto progress, so it is essential to be vigilant in reading food labels. Additionally, low-fat and diet items are often advertised as nutritious choices, but they frequently contain extra sugars and artificial sweeteners to compensate for the reduced fat content. The consumption of these products might hinder your keto progress by increasing your carbohydrate intake.
When following a keto diet, it is crucial to make informed choices and opt for whole, unprocessed foods that are naturally low in carbs. By avoiding trans fats and partially hydrogenated oils, you can promote overall health and support your body's optimal functioning while in ketosis.

Alcohol is okay, but stick to low-carb drinks like dry wine
The keto diet is a low-carb, high-fat diet often used to promote weight loss. The main objective is to transition the body's metabolism into a state called ketosis, where fat becomes the primary source of energy instead of carbohydrates. This is achieved by limiting carb intake to approximately 20 to 50 grams per day, causing the body to deplete its glycogen stores and shift to burning fat for fuel.
When it comes to alcohol, it is important to note that not all drinks are created equal. Alcoholic beverages can vary significantly in their carbohydrate content. Dry wines, for example, tend to be lower in carbs compared to sweet or dessert wines. The same can be said for liquors such as whiskey, gin, tequila, and vodka, which have no carbs and can be enjoyed in moderation on a keto diet.
However, it is crucial to be mindful of mixers and added sugars when consuming alcohol on a keto diet. Carbonated drinks, fruit juices, and sweet liquors like Baileys or Kahlua are often loaded with carbohydrates and sugars, quickly surpassing your daily carb allowance. Instead, opt for low-carb mixers like soda water, fresh lemon or lime juice, or sugar-free beverages. Additionally, be cautious with drinks that contain carbohydrates, such as beer and cider, as these can hinder your progress in achieving ketosis.
While alcohol can be incorporated into a keto diet, it is essential to prioritize nutrient-rich foods to avoid potential deficiencies associated with long-term keto dieting. Remember, the keto diet is not just about limiting carbs but also about ensuring adequate intake of essential vitamins, minerals, and fiber. Always consult with a registered dietitian nutritionist (RDN) to create a well-rounded plan that suits your individual needs and health goals.
In conclusion, while on a keto diet, it is best to stick to low-carb alcoholic beverages like dry wine, plain liquors, and low-carb mixers. As always, moderation is key, and ensuring a balanced and nutritious diet should take precedence.
