Keto Diet: What You Need To Know Before Starting

The keto diet is a high-fat, low-carb eating plan that can be tough to start. It's likely a radical departure from the standard American diet, which is high in carbohydrates and processed foods. The keto diet puts your body in a state of ketosis, where it burns fat for energy instead of carbohydrates. This can influence weight loss and type 2 diabetes, but more research is needed on the health effects of keto diets. Before starting keto, it's important to know what foods to eat and avoid, be prepared for possible side effects like the keto flu, and understand the potential risks and benefits. It's also crucial to consult a doctor or dietitian, especially if you have any health conditions or follow dietary restrictions. Keto requires a high-fat intake, which can be uncomfortable at first, so it's recommended to make gradual adjustments. Additionally, protein intake should be moderate, as too much can take the body out of ketosis. The keto diet is highly restrictive, cutting out grains, sugar, and certain fruits and vegetables, and it may not be suitable for everyone. It can be challenging to sustain due to its restrictiveness and potential side effects, including constipation, stomach issues, and fatigue. Proper meal planning and supplementation can help address these issues.

The keto diet is high-fat, very low-carb

The keto diet is a high-fat, very low-carb way of eating. It's more than just a diet—it's a lifestyle or way of eating (WOE) that requires consistency to be effective. The idea is to get your body into a metabolic state called ketosis, where it burns fat for energy instead of carbohydrates.

The ketogenic diet typically consists of 75% fat, 20% protein, and 5% carbohydrates. However, the daily carb intake can vary between 20 and 50 grams, depending on how your body processes carbs. To achieve ketosis, you need to severely limit your carb intake, starting with 20 to 30 grams of carbohydrates per day. This means cutting out grains, sugar, most fruits, starchy vegetables, and legumes. The only foods that don't contain carbs are meat (protein) and pure fats like butter and olive oil.

To compensate for the lack of carbs, you'll be eating healthy fats like olive oil, coconut oil, avocado, and nuts. Red meat, pork, poultry, and fish are also key components of the keto diet, along with full-fat dairy products like Greek yogurt, cottage cheese, and sour cream.

The keto diet can be challenging, especially if you fear fatty foods or are not prepared to drastically cut your carb intake. It's a significant departure from the standard American diet, which is typically high in carbohydrates and processed foods.

One of the challenges of the keto diet is adjusting to the high-fat content. To prepare for this, you can start making small changes to your diet, such as ordering a burger without the bun and opting for green vegetables instead of fries.

Another important aspect of the keto diet is moderating your protein intake. While it's a high-fat diet, it's not a high-protein one. Protein can be converted into glucose, so overeating protein can take your body out of ketosis.

The keto diet can lead to weight loss, but it's important to note that the initial weight loss is mostly water weight. The keto diet can also cause some unpleasant side effects, such as the keto flu, which includes symptoms like brain fog, drowsiness, headaches, and nausea.

Overall, the keto diet is a restrictive way of eating that requires time and commitment. It's important to consult with your doctor before starting the keto diet, especially if you have any pre-existing health conditions or concerns.

It's not for everyone

The keto diet is not a one-size-fits-all solution. While it has been shown to be effective for some people, it may not be suitable or sustainable for others. Here are some important considerations to keep in mind:

Strict Requirements and Discipline

The keto diet is highly restrictive and requires extreme discipline. It involves cutting out grains, certain fruits and vegetables, sugar, and starchy vegetables. This can be challenging and may not be feasible for those with dietary restrictions or preferences. For example, those who are vegan or vegetarian may find it especially difficult as the diet focuses heavily on meat and animal products.

Potential Health Risks

The keto diet is not without its risks. It can lead to lipid abnormalities and nutrient deficiencies, especially if not carefully planned and monitored. Some people may experience side effects such as constipation, stomach issues, depression, mood swings, fatigue, and even "keto flu," which includes symptoms like brain fog, fatigue, and nausea. It is crucial to consult a healthcare professional before starting the keto diet, especially if you have any pre-existing health conditions or are taking medications.

Long-Term Sustainability

The keto diet may not be sustainable for everyone in the long term due to its restrictiveness. It requires strict compliance, and even a small slice of pizza or cake for a co-worker's birthday can be considered a "cheat." This lack of flexibility may be challenging for some individuals. Additionally, the weight loss benefits may not be maintained if a person reverts to their previous eating habits after stopping the keto diet.

Individual Variability

The keto diet can affect people differently. While some may experience rapid weight loss, others may not see such drastic changes. Additionally, the time it takes to achieve ketosis, a state where the body burns fat for energy, can vary from person to person. Some may achieve it quickly, while others may take a slower approach.

Social and Lifestyle Impact

The keto diet can impact your social life and daily routines. It may require adjustments in your meal planning, grocery shopping, and dining out. Special occasions, such as birthdays or holidays, can also be challenging as they often involve food restrictions. Additionally, the keto diet may affect your energy levels, especially during the initial adjustment period, which can influence your exercise routines and daily activities.

It can be tough to start

The ketogenic diet can be a challenging one to start. It's likely a radical departure from the way you're eating now, especially if your current diet is high in carbohydrates and processed foods. The keto diet is highly restrictive, cutting out grains and certain fruits and vegetables in addition to sugar.

The keto diet is an ultra-low-carb diet, which means you'll be eating significantly fewer carbohydrates than the average person, even fewer than a person following a classic low-carb diet. Exactly how many carbs you should aim to eat depends on your specific goals, as well as your age, gender, and level of activity. Ketogenic diets tend to limit carbohydrate intake to just 20 to 30 net grams per day.

The keto diet is also high in fat, with fats typically making up 70 to 80 percent of total daily calories. This can be uncomfortable at first, so it's recommended to start making small adjustments to your diet before starting keto. For example, you could start cooking with more oil, such as olive or avocado oil, or opt for a non-starchy vegetable instead of potatoes or rice with your meal.

It's important to note that the keto diet is not a healthy, nutritionally complete diet. You are completely cutting out large groups of food and eating excessive amounts of fat, which can lead to lipid abnormalities. There are also concerns about the long-term effects of eating such a high-fat diet. If you're thinking about following the keto diet, it's important to talk to your doctor first.

Another challenge of starting the keto diet is that it can be difficult to get a good balance of sodium, magnesium, and potassium, as these nutrients mainly come from carb-rich foods such as beans, fruit, and potatoes. An imbalance can lead to "keto flu," which is when your body's electrolyte levels plummet. Symptoms of keto flu include brain fog, drowsiness, headaches, and even nausea.

Finally, it's important to be consistent with the keto diet and make it a permanent lifestyle change. Going on and off keto can mess up your metabolism and confuse your body, possibly causing you to gain more weight.

It may cause side effects like keto flu

The keto diet may cause side effects, commonly known as the "keto flu". This is a result of your body adjusting to burning fat for energy instead of carbohydrates. Symptoms of the keto flu include nausea, headaches, drowsiness, brain fog, and lethargy. In the first week or so of starting the keto diet, you may feel extremely tired and even climbing a flight of stairs may feel impossible.

The keto flu is caused by a drop in your body's electrolyte levels. On the keto diet, it can be challenging to get a good balance of sodium, magnesium, and potassium since these minerals typically come from carb-rich foods such as beans, fruits, and potatoes. To combat the keto flu, it is important to include plenty of foods that are high in magnesium (like almonds, spinach, and peanut butter) and potassium (like salmon, avocado, and leafy greens).

The keto flu usually passes within three to five days, but it is important to be prepared and give your body time to adjust. Pick a start date when you have a calm week ahead of you, and take it easy with exercise for the first week or two. Staying hydrated is also key to preventing or mitigating these side effects.

It's not a long-term solution

The keto diet is not meant to be a long-term solution. It is highly restrictive, cutting out grains, fruits, vegetables, and sugar. While it may be beneficial for short-term weight loss, it is not a sustainable diet due to its extreme restrictions. Here are some reasons why keto is not a long-term solution:

Health Risks

According to Diana Lehner-Gulotta, a registered dietitian, "The keto diet is not a healthy, nutritionally complete diet. You are completely cutting out large groups of food and eating excessive amounts of fat, which can lead to lipid abnormalities. We also don't know about the long-term effects of eating such a high-fat diet." The high fat content of the keto diet can lead to potential health risks, such as lipid abnormalities, constipation, stomach issues, depression, mood swings, and fatigue. The long-term effects of consuming a high-fat diet are still unknown and require further research.

Difficulty Sustaining

The keto diet is very restrictive and may be challenging to sustain in the long term. It requires strict compliance, and even a small slice of pizza or cake for a co-worker's birthday can cause you to exceed your daily carb limit. This lack of "wiggle room" in food choices can make the diet unrealistic and difficult to maintain.

Transitioning Off the Keto Diet

Transitioning off the keto diet requires careful planning. If you abruptly start eating carbs again while still consuming high amounts of fat, you may experience a dramatic weight rebound and harm your metabolism. It is essential to gradually add whole-food sources of carbs, such as sweet potatoes, fruits, and whole grains, while decreasing your fat intake.

Potential for Weight Regain

The initial weight loss on the keto diet is often attributed to a loss of water weight. When you start eating carbs again, you will likely regain the water weight, and the pounds can quickly pile back on. For most people, it is not realistic to remain on the keto diet indefinitely due to its restrictiveness. Therefore, there is a risk of regaining the weight lost once the diet is stopped.

Not a Permanent Solution

The keto diet should be viewed as a temporary measure rather than a permanent solution. It can be a useful tool for weight loss or managing specific medical conditions, but it is not designed to be followed indefinitely. In the long term, a balanced and nutritionally complete diet is generally recommended for maintaining overall health.
