When Can You Expect A Boost From Keto?

The ketogenic diet is a popular way to lose weight and improve health. It involves reducing your intake of carbohydrates and increasing your consumption of healthy fats. This dietary shift causes your body to enter a state called ketosis, where it burns fat for energy instead of carbohydrates. While ketosis can take a few days to several weeks to achieve, once you're in this state, you may experience increased and sustained energy levels.

The transition period: the first 10 days of keto

The first 10 days of keto can be a challenging transition period as your body adjusts to using ketones for fuel instead of glucose. Here's what you can expect during this time and some tips to help you through the process:

Day 1

On your first day of keto, you might feel fine as you start figuring out your new macro ratios, specifically eating 75% fat and keeping protein low at around 15%. This can be a big change compared to the Standard American Diet, and you might find it tricky to get used to.

Day 2

The second day is typically when the "carb flu" sets in, with symptoms like headaches, fatigue, muscle aches, nausea, brain fog, and irritability. Your body is working hard to adjust to the lack of carbohydrates, so be gentle with yourself and try to minimise your activity levels.

Day 3

Day 3 is often the most challenging day of the transition, as your body fully realises it's not getting carbs anymore and has to break down fats for fuel. Continue to be gentle with yourself, and if possible, take it easy at work or other activities.

Day 4

By day 4, you should start to see some improvement in your symptoms, and your body will be getting used to running off of fats for fuel. You might still feel some slight fatigue, but your energy levels will gradually improve. Use your newfound energy to meal prep for the upcoming week, as preparation is key to success during the transition.

Days 5-6

Towards the end of the first week, you'll likely feel more comfortable with your new diet and have a better understanding of what it looks and feels like to eat a high-fat, very low-carbohydrate diet. You may not have officially hit ketosis yet, but you can test your ketone levels with urine or blood tests to see how close you are.

Days 7-10

By the second week, the majority of people will have entered ketosis and will start feeling the benefits, including increased energy levels and reduced hunger. The "2pm slump" caused by blood sugar spikes and drops throughout the day should be a thing of the past. Remember to prioritise water intake as the high amount of ketones in your body can lead to dehydration.

The Standard American Diet vs keto

The Standard American Diet (SAD) is a way of eating that is largely based on convenience and the abundance of cheap, heavily processed foods. SAD is typically high in net carbs and fat, deficient in essential micronutrients, low in fiber, easy to overeat, and often leaves people feeling unsatisfied and wanting more. This can lead to excess calorie intake, nutrient deficiencies, and oxidative stress. Despite efforts to eat less and move more, SAD can eventually result in weight gain, high blood sugar, insulin resistance, heart disease, mental health issues, and metabolic syndrome.

In contrast, the ketogenic diet is a low-carb, high-fat diet that promotes weight loss and has been shown to reverse a range of diseases. By restricting carbs, the ketogenic diet can lead to dramatic improvements in blood sugar, triglycerides, blood pressure, and cholesterol. It also increases the body's metabolic flexibility and insulin sensitivity. The ketogenic diet has been found to be much more effective than SAD in treating metabolic syndrome, with sustained keto outperforming regular exercise and SAD combined.

When transitioning to a ketogenic diet, it is important to be mindful of potential keto fatigue. This can be caused by low salt intake, not being in a state of ketosis due to consuming too many carbs, an accidental low-calorie diet, and individual carbohydrate tolerance. To combat keto fatigue, it is recommended to increase salt intake, ensure a true ketogenic state by restricting carbs, be mindful of calorie intake, and identify and avoid certain carbohydrates that contribute to fatigue.

While the ketogenic diet offers many health benefits, it is important to note that it may not be suitable for everyone. Some people may experience side effects, such as keto flu, and there are potential risks associated with long-term adherence to the diet. It is always recommended to consult with a healthcare professional before making any significant dietary changes.

The role of insulin

When you start a keto diet, you essentially change the way your body fuels itself. The diet involves drastically reducing your carbohydrate intake and increasing your fat intake. This shift means your body has to adapt to using a different energy source, and this is where insulin plays a critical role.

Insulin is a hormone produced by the pancreas, and its primary role is to regulate the body's blood sugar levels. When you consume carbohydrates, they are broken down into glucose, causing your blood sugar levels to rise. In response, the pancreas releases insulin, which helps the body's cells take in this glucose to use as energy. Any excess glucose is then stored in the liver and muscles as glycogen.

On a keto diet, by reducing carbohydrate intake, you lower your blood sugar levels and, consequently, your insulin levels. This is key to achieving ketosis, a metabolic state where your body burns fat for energy instead of carbohydrates. When there is a lack of glucose from carbohydrates, your body starts breaking down stored fat, producing ketones, which can be used as an alternative energy source.

The reduction in insulin levels allows the body to access and utilise its fat stores more efficiently. Insulin is often referred to as a 'storage hormone', and high insulin levels signal the body to store energy as fat. Conversely, when insulin levels are low, as they are in ketosis, the body is encouraged to burn through these fat stores, leading to weight loss and increased energy.

The time it takes to enter ketosis and experience this energy boost varies between individuals. Factors such as physical activity levels, metabolic rate, and the strictness of your keto diet can influence this. However, understanding the role of insulin in this process provides insight into why the keto diet can lead to enhanced energy levels and other potential health benefits.

Ketosis and athletic performance

Ketosis is a metabolic state in which the body burns fat for energy instead of carbohydrates. This state is achieved by following a low-carb, high-fat diet, known as a ketogenic or keto diet. Athletic performance can be impacted by ketosis in several ways.

One of the key benefits of ketosis for athletes is enhanced fat burning. During ketosis, the body becomes more efficient at using fat for fuel, which can improve endurance and reduce reliance on carbohydrate stores. This is particularly advantageous for endurance athletes, as it may delay the onset of fatigue and improve performance over long durations.

Ketosis may also lead to improved blood sugar control and increased energy levels. By reducing carbohydrate intake, the body stabilizes blood sugar levels, preventing the spikes and crashes associated with carbohydrate-rich diets. This can provide athletes with sustained energy throughout their training and competitions. Additionally, ketosis has been anecdotally associated with increased mental clarity and focus, which could improve reaction times and decision-making during athletic performance.

However, there are also potential drawbacks to ketosis for athletes. Initially, during the adaptation phase to a ketogenic diet, athletes may experience reduced performance due to low muscle glycogen levels. This is known as the "keto-adaptation" period, where the body is adjusting to using fat as its primary fuel source. During this time, athletes may feel more fatigued and may need to reduce their training intensity temporarily.

Additionally, for athletes engaging in high-intensity anaerobic exercise, such as weightlifting or sprinting, ketosis may not be optimal. These types of exercises rely primarily on carbohydrates for fuel, and the body may struggle to provide sufficient energy from fat sources during short-duration, high-intensity bursts. Therefore, athletes in these sports may benefit from a modified ketogenic diet that includes strategic carbohydrate intake around training sessions.

Overall, the impact of ketosis on athletic performance is complex and highly individual. Some athletes may thrive on a ketogenic diet, experiencing improved endurance and sustained energy levels. Others, particularly those in anaerobic sports, may find that a modified approach or a different nutritional strategy altogether is more suitable. Personalized experimentation and monitoring are crucial to determine the optimal approach for enhancing athletic performance.

The impact of keto on women

The keto diet has been a popular topic in the health and wellness space for several years, with many people, including women, adopting it for its potential weight loss and health benefits. The diet involves a significant reduction in carbohydrate intake and a shift towards a higher fat and moderate protein intake. While the keto diet can offer some advantages to women, there are also potential challenges and risks to consider.

One of the key impacts of keto on women is related to energy levels. Some women report experiencing an increase in energy and mental clarity while on keto. This boost in energy can be beneficial for managing daily tasks, increasing productivity, and improving overall well-being. The timing of this energy boost can vary, with some women experiencing it within the first week of starting keto, while for others, it may take several weeks or even months.

Another important consideration for women on keto is hormonal balance. The diet may impact hormone levels, especially those related to reproductive health. Some women could experience improvements in hormonal acne, polycystic ovary syndrome (PCOS), and menstrual irregularities. On the other hand, there is also a possibility of initial hormone fluctuations, potentially leading to temporary menstrual cycle changes or missed periods. Women should monitor their cycles and consult a healthcare professional for any concerns or persistent symptoms.

Additionally, the keto diet may influence a woman's menopause experience. While some women report reduced hot flashes and improved mood on keto, the diet might also affect hormone balance during this delicate transition. Women going through menopause should work closely with a healthcare provider to ensure the keto diet supports their individual needs and does not exacerbate any menopause-related symptoms.

The keto diet can also impact women's nutritional requirements. It is important for women to ensure they obtain adequate nutrients typically gained from carbohydrate-rich foods, such as vitamins, minerals, and fiber. Careful meal planning and supplementation may be necessary to prevent nutritional deficiencies. For instance, women on keto may need to increase their intake of leafy greens and supplement with minerals like magnesium and potassium to maintain their overall health.

In conclusion, while the keto diet may offer some benefits to women, it should be approached with caution and individualized guidance. Women should closely monitor their bodies' responses and be mindful of potential challenges related to energy levels, hormonal balance, menopause, and nutritional requirements. Consulting with a healthcare professional or nutritionist experienced in keto diets can ensure a tailored approach that meets each woman's unique needs.
