Keto Hunger: How Long Does It Last?

The ketogenic diet is a high-fat, low-carb, moderate-protein eating plan that can help suppress hunger and appetite. While the diet is often associated with restrictions, it is actually a satisfying way of eating that does not require you to feel hungry.

Ketosis, the metabolic state that the diet induces, changes your metabolism so that your body begins breaking down fats for fuel instead of carbohydrates, producing ketone bodies as fatty acids are broken down. This process reduces your appetite and cravings for foods that typically lead to overeating, such as sugar and carbs.

However, some people may still experience hunger on the keto diet, especially when they are first starting out. This could be due to a variety of reasons, including carb addiction, sleep deprivation, stress and anxiety, dehydration, or not consuming enough fat. Addressing these issues can help reduce hunger and make the keto diet a more sustainable and enjoyable way of eating.

Hunger due to carb addiction

This is because, for most of human evolution, our ancestors only had intermittent access to high-carb foods like fruits. Our bodies learned to tell us to consume as much sugar as possible and store the excess as fat for leaner periods.

On a keto diet, when we cut out most sources of carbs, our bodies can be flooded with hunger hormones, crying out for the sugar to which we've become accustomed. This can lead to intense sugar cravings and increased hunger, especially when starting a keto diet.

The good news is that this is only temporary. It can take a week or two for sugar-craving yeasts and bacteria in our gut to die off and be replaced. In the meantime, it's important to stick with the keto diet and avoid artificial sweeteners, which can trigger sugar cravings in the brain.

To combat hunger due to carb addiction, it's crucial to increase your fat intake. The keto diet is high in fat, moderate in protein, and low in carbs. Make sure you're getting enough healthy fats, such as those found in keto meats, fatty fish, and healthy oils like olive and avocado oil.

• Start your day with a fatty, buttery keto coffee.
• Make your own salad dressings with herbs, lemon, salt, pepper, and fatty oils.
• Coat your veggies in butter to increase your fat intake and make them taste better.
• Include more omega-3s in your diet, such as grass-fed butter, olive oil, and other animal fats.
• Don't deprive yourself. Eat enough food to feel full and give your body plenty of nourishment.
• Cut back on artificial sweeteners, which can increase sugar cravings.

Hunger due to sleep deprivation

Sleep and appetite are closely connected. Sleep deprivation can negatively impact your health and physical well-being in several ways, and one of the outcomes is an increase in calorie consumption. A lack of sleep can also lead to poor diet quality and excessive body weight.

The Link Between Sleep and Appetite

The relationship between sleep loss and overeating is likely due to changes in hormonal functions in the body. Getting a good night's rest promotes the healthy production of hormones that control appetite, digestion, and metabolism. These include leptin and ghrelin. Leptin is a peptide hormone that regulates your body's energy balance by reducing feelings of hunger and regulating fat storage. Ghrelin, on the other hand, boosts appetite, growth, and fat production.

When you don't get enough sleep, your body produces less leptin and more ghrelin. This imbalance can lead to increased feelings of hunger during the day, making you more likely to consume more calories and gain weight.

The Impact of Sleep Loss on Calorie Intake and Food Choices

Research has shown that sleep-deprived people tend to consume fewer fats and proteins while their carbohydrate intake remains the same. Additionally, sleep loss can impact how your body reacts to insulin production, putting you at higher risk for diabetes.

Strategies to Improve Sleep

To combat the negative effects of sleep deprivation on appetite and weight, it is essential to prioritize sleep hygiene and aim for the recommended seven to nine hours of sleep per night. Here are some tactics that may help:

• Monitor sleep times using wrist actigraphy devices such as smartwatches.
• Evaluate your bedtime routine and make changes to factors that may be disrupting your sleep duration.
• Limit the use of electronic devices at least an hour before bed.

By addressing sleep deprivation and improving sleep quality, you can help regulate your appetite and support your weight management efforts.

Hunger due to stress and anxiety

Hunger and cravings are usually reduced on a ketogenic diet as the body enters a state of ketosis, but some people may still experience hunger, especially when they are new to the diet. Hunger due to stress and anxiety is one of the reasons for this.

Chronic stress and high levels of cortisol (the stress hormone) in the blood can increase the hunger hormone ghrelin. This can lead to weight gain and obesity. Stress and anxiety can also be mistaken for physical hunger, and it can be challenging to distinguish between the two. Here are some signs that may indicate that your hunger is related to stress:

• It slowly develops over time.
• You have a desire for fat and protein.
• You crave high-carb foods and sweets.
• You notice when you're full and can stop eating.
• You binge eat and don't acknowledge feelings of fullness.
• You feel positive about eating.
• You feel guilty or ashamed after eating.

If you think your hunger is due to stress and anxiety, there are some techniques you can try to manage it:

• Meditation for stress and anxiety.
• Yoga nidra full-body relaxation.
• Breathing techniques for anxiety.

Additionally, it's important to ensure you're getting enough sleep, as sleep deprivation can also contribute to increased hunger and cravings. Aim for at least 7 hours of sleep per night.

Mistaking dehydration for hunger

It is common to confuse thirst with hunger, and this happens because the signals for thirst are weaker than those for hunger. In fact, clinical studies have shown that 37% of people mistake thirst for hunger.

When you are truly hungry, you will likely experience an empty feeling in your stomach, a stomach that is gurgling or rumbling, dizziness, faintness, or light-headedness, and a lack of concentration. However, when you are thirsty, you may experience similar symptoms, such as an empty feeling in your stomach, fatigue, lightheadedness, and difficulty concentrating.

To avoid mistaking thirst for hunger, it is important to stay hydrated throughout the day. Aim to drink enough water so that your urine is very pale yellow. If you are well-hydrated, it will be easier to identify true hunger.

Additionally, pay attention to how hunger feels for you. Hunger usually grows gradually as the time since your last meal increases.

It is also important to note that hunger due to dehydration can occur when transitioning to a keto diet. During this period, your body flushes fluids after metabolizing the glucose stored in your muscles, which can lead to dehydration.

Not eating enough fat

The ketogenic diet is well-known for its high intake of healthy fats, but it is possible to neglect this aspect and not consume enough fat to feel satisfied. With fat being your main source of energy on a keto diet, you will feel hungry if you are not getting your daily macronutrients.

Over 70% of your daily calories should be from fat. To boost your fat intake, try fat bombs, healthy fats and oils like coconut oil, and fatty foods like fish, meats, nuts, seeds, and avocados. You can also make your own salad dressings with herbs, lemon, salt, pepper, and fatty oils like olive, avocado, and walnut.

• Add butter to your veggies. This will not only make them taste better but also increase your fat intake.
• Start your day with a fatty, buttery coffee. Try adding MCT oil, butter, and other fats to your morning coffee.
• Eat more fatty and nutrient-dense foods. This includes keto meats like ribeye steak, lamb, and pork, fatty fish like mackerel, anchovies, and salmon, and healthy fats like high-fat keto cheese.
• Make your own salad dressings. Use herbs, lemon, salt, pepper, and fatty oils like olive, avocado, and walnut.
• Try fat bombs. These are treats that provide your body with macro-boosting satiety. You can find many recipes online, such as cookies and cream fat bombs, shelf-stable fat bombs, or almond joy fat bombs.

By ensuring you are consuming enough fat, you will feel more satisfied and less hungry while following a keto diet.
