Low-carb diets are gaining popularity, especially among women, for their potential to aid in weight loss and stabilize blood sugar levels. This article provides a structured 10-day keto challenge plan, explaining what to eat, what to avoid, and offering a sample menu to help you experience the benefits of a low-carb lifestyle.
Understanding "No Carb, No Sugar"
A "no-carb, no-sugar" diet focuses on minimizing digestible carbohydrates while emphasizing protein and healthy fats. Different forms of low-carb diets exist:
- Low-carbohydrate: 26% or less of daily calories from carbs (less than 130 g/day).
- Very-low-carbohydrate: 10% or less of daily calories from carbs (20 to 50 g/day).
It's crucial to understand the difference between total carbs and net carbs:
- Total Carbs: The total carbohydrate content of food, including sugars, starches, and fiber.
- Net Carbs: The digestible carbohydrate content, calculated by subtracting non-digestible carbs (fiber and sugar alcohols) from total carbs.
Calculating net carbs allows you to maintain fiber intake, which is essential for gut health, bowel function, cholesterol management, and blood glucose regulation. Fiber and sugar alcohols are subtracted from the "Total Carbohydrates" listed on the food label to arrive at the net carb count. This seemingly small distinction can be significant when carb intake is severely restricted.
Realistic Benefits in 10 Days
The fundamental principle of weight loss is consuming fewer calories than your body expends. Reducing carb intake naturally increases the proportion of fat and protein in your diet. Studies suggest that decreasing carbohydrate consumption prompts the body to utilize glycogen (stored carbohydrates) from the liver and muscles. Once these glycogen stores are depleted, the body starts burning fat for energy.

Fat, being the most energy-dense macronutrient (9 calories per gram), provides a sustained energy source. This shift towards fat utilization and reduced carbohydrate intake can lead to better glycemic control, stabilized energy levels, and reduced insulin resistance. Increased protein intake can further enhance satiety and increase thermogenesis (energy expenditure during digestion), contributing to both reduced calorie consumption and increased calorie burning, which is beneficial for fat loss.
The depletion of glycogen also leads to water weight loss, as each gram of glycogen holds approximately 3 to 4 grams of water. Furthermore, switching to nutrient-dense alternatives provides the body with essential vitamins and minerals, supporting vital organs and systems for improved long-term health.
Individual results may vary, and carefully calculating your calorie requirements based on age is recommended. Daily calorie needs differ between individuals in their 40s, 50s, and 60s.
Who Should and Shouldn't Try This Reset
The primary reason to adopt a low-carb diet is to lose weight. Limiting carbohydrate intake involves eliminating refined carbohydrates found in pastries, white bread, processed foods, and sugary drinks, which are linked to negative health outcomes like type 2 diabetes, obesity, high blood pressure, and cardiovascular disease.
However, drastically cutting a major macronutrient is not suitable for everyone, particularly pregnant or breastfeeding women and athletes who require significant energy. It should also be avoided by individuals with kidney damage, gout, or type 1 diabetes. High protein diets can potentially harm the kidneys and increase the risk of gout, while those with type 1 diabetes may experience sustained hyperglycemia.

It is crucial to monitor changes in energy levels, mood, and bowel movements, and to consult a healthcare provider before making significant dietary changes. A healthcare professional can tailor the plan to your specific health history. Remember, this 10-day plan serves as a short-term reset to establish healthy habits for long-term well-being.
Guidelines for Success
Reducing carbohydrate intake can initially cause hunger and low energy as the body adapts. To mitigate these effects, consider these guidelines:
- Daily protein targets: Ensure adequate protein intake.
- Focusing on fat for satiety: Prioritize healthy fats to promote feelings of fullness.
- Eliminating Starchy vegetables: Avoid starchy vegetables.
- Maintaining hydration and electrolytes: Stay well-hydrated and replenish electrolytes.
- Avoiding added sugars: Strictly avoid added sugars.
Adhering to these guidelines will improve compliance and enhance results.
Foods to Avoid
During the 10-day challenge, avoid the following:
- Grains: Rice, bread, pasta, quinoa, millet, barley
- Starchy Vegetables: Potatoes, sweet potatoes, corn, peas, parsnips, beets
- Dairy: Milk, oat milk, rice milk, butter milk, flavored milk, ice cream, flavored yogurt
- Sweetened Drinks: Soda, fruit juice, sweetened coffee
- Alcohol: Beer, mixed drinks, liquors, cider, wine
- Condiments: Ketchup, BBQ sauce, teriyaki sauce, honey mustard, sweet chili sauce
Be mindful of hidden sugars, which can be listed as:

Foods to Enjoy
Focus on these nutrient-dense foods:
- Meat: Beef, lamb, pork
- Poultry: Chicken, turkey, duck, eggs
- Seafood: Salmon, mackerel, sardines, tuna, cod, shrimp, lobster, crab, mussels
- Plant-Based: Tofu, tempeh
- Low-carb vegetables: Spinach, kale, lettuce, broccoli, cauliflower, cabbage, zucchini, asparagus, avocado, mushrooms, cucumber, green beans, peppers
- Nuts: Pecans, macadamia nuts, Brazil nuts, walnuts, almonds, hazelnuts
- Herbs/spices: Basil, oregano, thyme, cilantro, parsley, rosemary, salt, pepper, cumin, cinnamon, turmeric, paprika
- Oils: Extra virgin olive oil, avocado oil, coconut oil, butter, ghee, lard, tallow
- Zero calorie sweeteners: Stevia, monk fruit, sucralose, aspartame
- Protein supplements: Whey protein isolate (low-carb)
Herbs and spices can enhance the flavor of your meals. If you use protein supplements, opt for whey protein isolate, which is low in carbs.
Electrolytes and Hydration
Electrolytes and adequate hydration are crucial during low-carb diets. As glycogen stores deplete, water is lost, impacting hydration. Electrolytes like sodium, potassium, chloride, magnesium, calcium, phosphate, and bicarbonate are essential for fluid balance, nerve impulses, and muscle contraction.
Individuals following a very-low-carb diet may experience the "keto-flu," characterized by weakness, fatigue, and muscle cramps. Electrolyte drinks can help maintain hydration and support nerve and muscle function. Aim for a daily water intake of around 2,200 ml for women to support overall health and potentially aid in weight loss by reducing hunger and energy intake before meals.

The Keto Diet: An Overview
The ketogenic diet is a high-fat, low-carb diet that forces the body to use fat for energy through a process called ketosis. The typical macronutrient breakdown is:
- Carbs: 5-10%
- Fats: 70-75%
- Protein: 15-20%
During ketosis, the liver produces ketones from fats, serving as an alternative fuel source when glucose is limited. Keto diets can also reduce hunger and increase satiety, aiding in weight loss.
Keto-Friendly Foods
Focus on these foods when following a ketogenic diet:
- Eggs: Pastured, organic, or conventional
- Poultry: Chicken and turkey
- Fatty fish: Salmon, herring, and mackerel
- Meat: Beef, venison, pork, organ meats, and bison

- Full-fat cheese: Cheddar, mozzarella, brie, goat cheese, and cream cheese
- Nuts and seeds: Macadamia nuts, almonds, walnuts, pumpkin seeds, peanuts, and flaxseeds
- Nut butter: No-sugar-added peanut, almond, and cashew butters
- Oils rich in healthy fats: Olive oil, avocado oil, and sesame oil
- Avocados: Whole avocados
- Non-starchy vegetables: Greens, broccoli, tomatoes, mushrooms, and peppers
- Condiments: Salt, pepper, vinegar, lemon juice, fresh herbs, and spices
Foods to Limit
Limit or avoid the following foods:
- Bread and baked goods: White bread, whole wheat bread, crackers, cookies, doughnuts, and rolls

- Weight regain: Stopping the diet can lead to weight regain.
- Not for everyone: The keto diet is not recommended for everyone.
- Cholesterol impact: A keto diet is typically high in saturated fat and trans fats.
- Fiber and vitamins: It can also be low in vegetables, grains, and legumes.
- Restrictive: The diet is very restrictive and needs careful planning, which makes it hard to sustain.
- Pregnancy and nursing parents: It may not be safe for those who are pregnant or nursing.
Keto and Diabetes
The keto diet has the potential to increase insulin sensitivity in individuals who are managing diabetes, as research suggests. A ketogenic diet may cause a reduction in A1C, something that may help you reduce medication use.
Keto and Weight Loss
Ketogenic diets will cause you to lose weight within the first week. One review suggested that this low-carb diet can spur fat loss in people with obesity when used for a couple of weeks and for up to one year.
