The ketogenic diet (KD), a very low-carb, high-fat dietary approach, has garnered significant attention for its potential health benefits, particularly in the realm of weight loss. This article delves into the experiences and results of women following a ketogenic diet over a 3-month period, drawing upon scientific studies and anecdotal evidence.
Understanding the Ketogenic Diet
The ketogenic diet is characterized by a drastic reduction in carbohydrate intake, typically limiting it to 20-50 grams per day. This restriction forces the body into a metabolic state called ketosis, where it shifts from using glucose (derived from carbohydrates) to fat as its primary fuel source. The liver converts fat into ketones, which then serve as an energy source for the brain and other organs.
Types of Ketogenic Diets
While various versions of the KD exist, the most common and well-researched include:
- Standard Ketogenic Diet (SKD): A very low-carb, moderate-protein, and high-fat diet, typically composed of 70% fat, 20% protein, and 10% carbohydrates.
- High-Protein Ketogenic Diet: Similar to the SKD but with a higher protein intake, often consisting of 60% fat, 35% protein, and 5% carbohydrates.
Cyclical and targeted ketogenic diets are more advanced approaches usually employed by bodybuilders or athletes.
Benefits of the Ketogenic Diet
Beyond weight loss, the ketogenic diet has been associated with several potential health benefits:

- Improved Insulin Sensitivity: Studies suggest that KD can enhance insulin sensitivity, which is particularly beneficial for individuals with type 2 diabetes or prediabetes.
- Reduced Blood Sugar Levels: By limiting carbohydrate intake, KD can help lower blood sugar levels, potentially reducing the need for blood sugar medications in individuals with type 2 diabetes.
- Potential Benefits for Neurological Disorders: Research indicates that KD may have therapeutic potential for neurological conditions such as Alzheimer's disease, epilepsy, and Parkinson's disease.
- Heart Health: KD may improve risk factors associated with heart disease, such as body fat, HDL (good) cholesterol levels, blood pressure, and blood sugar.
3-Month Keto Results: What to Expect for Women
Weight loss is a common goal for individuals adopting a ketogenic diet. During the first week, as the body depletes its glycogen stores, rapid weight loss often occurs due to water loss. After the first week, once you’ve used up glycogen stores, your body will move into ketosis and begin to burn fat. Although the rate of weight loss may slow a little, this is the time where you really start to notice a difference. You will gradually become leaner and your body will begin to change shape.
Initial Weight Loss and Adaptation (Month 1)
During the first month, significant weight loss is often observed. For reference, my starting weight was 123 pounds, so shaving 6 pounds off is a pretty big deal. Within the first 3 weeks, I had lost 6 pounds. This is primarily due to water loss and the body's initial adaptation to burning fat for fuel. However, some individuals may experience the "keto flu," a collection of symptoms such as fatigue, headache, and nausea, as the body adjusts to ketosis. To mitigate these effects, it's crucial to stay hydrated, consume electrolytes, and ensure adequate mineral intake.
Continued Fat Loss and Body Composition Changes (Month 2)
In the second month, weight loss may continue, although at a slower pace. As I progressed through the second month of the Keto diet, I noticed that the weight was still coming off but at a slower pace. This may also because of the holiday gorging I engaged in during Thanksgiving and the current holiday season. The body becomes more efficient at burning fat, leading to further reductions in body fat percentage. It’s a really good idea to calculate your macros too. This will ensure you’re eating the right percentage of macros for your body. Calculating your macros takes into account your gender, height, weight and activity level so you can have an individualised eating plan - to the gram.
Maintenance and Long-Term Considerations (Month 3)
After 3 months of following Keto, most people find weight loss slows down further; perhaps only losing 1-2lbs every couple of weeks. Most of your weight loss will have happened at this stage, and you may have already reached your target weight. By the third month, weight loss may plateau as the body reaches a new equilibrium. It's essential to recalculate your macro amounts by 3 months into Keto. Adjust the amounts for what your body and lifestyle is like 3 months in. Focus shifts towards maintaining the achieved weight loss and optimizing body composition. This involves making informed food choices, incorporating regular exercise, and addressing any potential nutrient deficiencies.
A Study on Ketogenic Diet in Recreationally Trained CrossFit Trainees
A 12-week study examined the effects of a ketogenic diet (KD) on body composition, metabolic parameters, and performance in recreationally-trained CrossFit participants. Twelve participants (nine males and three females) were divided into a control group (CTL) and a KD group. KD participants followed specific dietary guidelines, while CTL participants maintained their normal diet, with all participants continuing their CrossFit training routine.

Key Findings
- Fat Loss: DXA fat mass decreased by 12.4% in the KD group (p = 0.053).
- Lean Body Mass: DXA total lean body mass changes were not significantly different between groups. However, DXA dual-leg lean mass decreased in the KD group by 1.4% (p = 0.068), and vastus lateralis thickness values decreased in the KD group by ~8% (p = 0.065).
- Cholesterol Levels: LDL cholesterol increased ~35% in the KD group (p = 0.048).
- Performance: Changes in REE, one-repetition maximum (1-RM) back squat, 400 m run times, and VO2peak were similar between groups.
These preliminary data suggest that a ketogenic diet can lead to significant reductions in body fat without negatively impacting performance in recreationally-trained CrossFit athletes.
Practical Tips for Women Following a Ketogenic Diet
- Plan your meals: Plan your meals in advance and use a meal tracking app.
- Calculate your macros: It’s a really good idea to calculate your macros too. This will ensure you’re eating the right percentage of macros for your body. Calculating your macros takes into account your gender, height, weight and activity level so you can have an individualised eating plan - to the gram.
- Focus on whole, unprocessed foods: Base your diet on foods such as meat, fish, eggs, butter, nuts, healthy oils, avocados, and plenty of low carb veggies.
- Stay hydrated: Drink plenty of water throughout the day to combat dehydration and electrolyte imbalances.
- Listen to your body: Pay attention to how you feel and adjust your diet and exercise routine accordingly.
- Seek professional guidance: Consult with a registered dietitian or healthcare professional to personalize your ketogenic diet plan and address any specific health concerns.
Potential Side Effects and Considerations
While the ketogenic diet can be effective for weight loss and overall health, it's essential to be aware of potential side effects and considerations:
- Keto Flu: As mentioned earlier, the "keto flu" can occur during the initial adaptation phase.
- Nutrient Deficiencies: Restricting certain food groups can lead to nutrient deficiencies. It's crucial to consume a variety of nutrient-dense foods and consider supplementation if necessary.
- Digestive Issues: Some individuals may experience constipation or other digestive issues due to the low fiber content of the ketogenic diet.
- Elevated Cholesterol Levels: As observed in the CrossFit study, LDL cholesterol levels may increase in some individuals following a ketogenic diet. Regular monitoring of cholesterol levels is recommended.
- Long-Term Sustainability: The long-term sustainability of the ketogenic diet is a concern for some individuals. It's essential to find a dietary approach that aligns with your lifestyle and preferences.
Success Stories and Transformations
Numerous women have shared their positive experiences with the ketogenic diet. Janice, a yo-yo dieter, found success with keto after years of struggling with weight loss. “I was NEVER able to lose body fat before keto. It’s not just the weight loss, though. “No more worrying about how much I eat,” she says. Today, Janice’s concerns about eating so much fat have vanished. “My lipid levels are amazing! HDL is 91, triglycerides 48. Her story serves as an inspiration, highlighting the potential of keto for weight loss and overall health improvement.
