Keto And Working Out: What's The Best Strategy?

Combining the keto diet with a workout routine can be a powerful way to improve your health and fitness. However, it's important to be aware of some key considerations before diving into this combination. The keto diet involves a significant reduction in carbohydrate intake, which can impact your energy levels and athletic performance, especially during high-intensity exercises.

When you start the keto diet, your body enters a state called ketosis, where it burns fat for fuel instead of carbohydrates. This metabolic shift can lead to initial side effects, such as the infamous keto flu, which may include symptoms like mental fog, nausea, fatigue, and headaches. These side effects can affect your motivation and ability to work out.

Additionally, the keto diet may not be optimal for high-intensity exercises that rely on short bursts of energy. Carbohydrates are the main fuel source for these types of activities, and the reduced availability of carbs on the keto diet can limit performance. However, the keto diet may enhance fat burning during low- to moderate-intensity exercises, such as jogging, cycling, or yoga.

To optimize your experience with the keto diet and workouts, it's crucial to listen to your body, ensure proper hydration, maintain adequate electrolyte levels, and adjust your exercise routine and diet as needed. Some people choose to incorporate modified versions of the keto diet, such as the Targeted Ketogenic Diet (TKD) or Cyclical Ketogenic Diet (CKD), to better suit their workout routines and performance goals.

In summary, while combining the keto diet with working out can be beneficial, it's important to be mindful of potential challenges and adjust your approach accordingly.

The keto diet may boost fat burning

The keto diet is a low-carb, high-fat, and moderate-protein diet. It is based on the idea of achieving a metabolic state called ketosis, where the body uses fat and ketone bodies as its primary source of energy instead of carbohydrates. This shift in energy sources can have a significant impact on fat burning capabilities.

When following a keto diet, the body's primary source of energy comes from fat and ketone bodies. This shift in fuel sources means that the body becomes more efficient at burning fat for energy. The body can tap into its fat stores more readily and utilise them as a readily available energy source. This increased reliance on fat metabolism can lead to a higher rate of fat burning, even during rest and low to moderate-intensity physical activities.

Several studies have indicated that the keto diet may indeed boost fat burning capabilities. One study involving competitive race walkers showed that the keto diet increased the body's ability to burn fat during workouts, even at different intensity levels. Another study with 22 athletes found that switching to a keto diet increased fat burning capabilities over a four-week period.

Additionally, a study in the Journal of Strength and Conditioning Research found that resistance training while on the keto diet may lead to an increase in lean body mass, suggesting that the keto diet may help preserve or even build muscle mass while burning fat.

While the keto diet may boost fat burning, it is important to consider potential drawbacks. The keto diet can be challenging to maintain due to its restrictive nature, and it may not be suitable for everyone. It can cause side effects such as the keto flu, which includes symptoms like fatigue, nausea, and headaches. Additionally, the keto diet may negatively impact high-intensity workouts and athletic performance due to the reduced availability of carbohydrates for quick energy bursts.

Furthermore, the keto diet may not be suitable for long-term weight loss. While it can lead to initial weight loss, some research suggests that the effects may diminish over time, and weight regain may occur.

The keto diet has the potential to boost fat burning by increasing the body's reliance on fat as a fuel source. However, it is important to consider the potential drawbacks, including side effects, challenges with adhering to the diet, and possible negative impacts on high-intensity exercise performance. More research is needed to fully understand the long-term effects of the keto diet on fat burning and weight loss.

It may be tougher to boost performance with high-intensity exercise

Starting the keto diet and working out at the same time can be challenging. While it's not impossible, it will definitely be different. That's because your body will be running on fat for fuel instead of energy-boosting carbs.

The Body's Preferred Energy Source

The body's preferred source of energy is glucose, which is derived from carbohydrates. On a typical diet, glucose and glycogen (a.k.a. sugar and carbs) are stored in the muscles for quick energy. However, the keto diet depletes these stores, leaving the body with just fat to burn, which is not as readily available as carbs.

High-Intensity Exercise Requires Quick Energy

High-intensity exercises like HIIT, sprinting, or weightlifting require quick bursts of energy. Because fat is not as readily available to muscles for energy as carbs, these types of exercises will be more strenuous.

Endurance May Suffer

You may find that you have less endurance during exercise and "hit a wall" earlier in your workout. This is because your body will be using fat as its main source of energy, which takes longer to access than glycogen.

Low-Intensity Exercise Is Better

Low-intensity aerobic exercises like yoga, jogging, and biking will be easier on your body as it uses fat as its main source of energy. It's important to take it easy at first and start with low-to-moderate intensity, short-duration workouts when beginning the keto diet.

The Keto Diet May Not Be for Everyone

If you enjoy going all out at the gym, the keto diet may not be the best choice for you. Working out just won't feel as good as it did pre-ketosis.

You may feel less energised at first

Starting the keto diet and a workout routine simultaneously can be challenging. You may feel less energised initially, and this is perfectly normal. Your body is adjusting to using fat as its primary fuel source instead of carbohydrates, which can result in a decrease in energy levels. This is known as the "keto flu," characterised by flu-like grogginess and stomach upsets that typically pass within a few days to a couple of weeks.

During this adjustment period, it is essential to listen to your body and not push yourself too hard. You may need to reduce the intensity of your workouts or try low-intensity exercises such as yoga, jogging, or biking. This doesn't mean you have to skip working out altogether, but adjusting your routine can help you manage your energy levels effectively.

Additionally, make sure you are consuming enough calories and staying properly hydrated. Drinking plenty of water is crucial when following the keto diet to prevent dehydration and maintain optimal bodily functions. It is also important to maintain adequate electrolyte levels, as the keto diet can flush out a lot of water and electrolytes from your body.

While you may experience a decrease in energy levels at the beginning of your keto journey, this effect is usually temporary. Once your body becomes "keto-adapted" and more efficient at burning fat for fuel, your energy levels and physical performance will likely return to baseline or even improve. This adaptation process may take a few weeks, so be patient and focus on listening to your body's needs during this time.

To summarise, it is normal to feel less energised when starting the keto diet and a workout routine simultaneously. Be mindful of your body's signals, adjust your workout intensity if needed, and stay properly hydrated and nourished. Remember that this lack of energy is typically temporary, and your body will adapt to using fat as fuel more efficiently over time.

Your body may burn calories quicker

The ketogenic diet is a very low-carb, high-fat, and moderate-protein diet. It encourages the consumption of healthy fats and discourages the consumption of carbohydrates. When on a keto diet, the body enters a state of ketosis, where it burns fat for fuel instead of carbohydrates.

A 2018 study found that when overweight adults replaced carbohydrates in their diet with fat for a period of five months, their bodies were able to burn approximately 250 more calories per day than people who ate high-carbohydrate and low-fat diets. This is because fat contains a significantly higher number of calories per gram than carbohydrates.

However, it is important to note that gram for gram, fat has more calories than carbohydrates. Each gram of fat has 9 calories, while a gram of protein or carbohydrate has 4 calories. Therefore, it is still necessary to create a calorie deficit by consuming fewer calories than you burn if you want to lose weight on the ketogenic diet.

Additionally, the type of workout matters when it comes to burning calories on the keto diet. Low-intensity, steady-state workouts (like jogging or cycling) tend to be less affected by the diet, while high-intensity workouts (like HIIT or weightlifting) may be more challenging due to the lack of carbohydrates available for fuel.

Overall, the keto diet can be an effective way to burn more calories and lose weight, but it is important to combine it with the right types of exercise and a calorie deficit for optimal results.

Keto is better for maintaining muscle mass than adding it

Starting a keto diet and a workout routine at the same time can be challenging. The keto diet is a very low-carb, high-fat diet that encourages your body to use ketones as fuel rather than glucose, which is the body's preferred source of energy. While it can be effective for weight loss and has various health benefits, it may not be the best choice if your goal is to build muscle mass.

Keto and muscle maintenance:

The keto diet can be effective for maintaining muscle mass, especially for those who are already active and have an established workout routine. Studies have shown that the keto diet can help preserve lean body mass while losing weight, which is crucial for overall health and can also have benefits for bone health and cognitive function.

Building muscle on keto:

While it is possible to build muscle on a keto diet, it may be more challenging than on a traditional higher-carb diet. This is because muscle growth requires a significant amount of protein, and some versions of the keto diet may involve restricting protein intake. Additionally, keto diets are often low in calories, which can make it difficult to consume enough protein to support muscle growth.

Energy levels and endurance:

The keto diet can impact energy levels, especially during high-intensity workouts. This is because carbohydrates are the main source of energy for these types of activities. As a result, it may be difficult to perform at the same intensity as you could on a higher-carb diet. However, the keto diet may enhance endurance for low- to moderate-intensity exercises, as the body learns to use fat as an alternative fuel source.

Adjusting your workout routine:

When starting a keto diet, it is recommended to focus on low- to moderate-intensity exercises such as yoga, jogging, biking, and swimming. High-intensity workouts like HIIT, sprinting, or weightlifting may be more challenging and could lead to faster fatigue. It's important to listen to your body and adjust your workout routine as needed.

Timing your carb intake:

One strategy to consider is timing your carb intake around your workouts. This approach, known as a targeted keto diet, can help provide your body with the fuel it needs for high-intensity exercises. However, it's important to note that this may affect your ketosis state.

In conclusion, while the keto diet can be effective for maintaining muscle mass, building significant muscle mass on keto may be challenging due to the restricted protein and calorie intake. If your primary goal is to build muscle, you may need to adjust your diet to include more protein and carbohydrates. However, if you're looking to maintain your muscle mass while losing weight, the keto diet could be a good option, especially when coupled with a suitable workout routine.
