4 min read

One intriguing study found that dieters on a low-carb regimen, even when given more calories, often maintained significant weight loss, likely due to reduced hunger. If you're wondering how to get enough calories on a low-carb diet, the key is focusing on energy-dense, satisfying foods that keep you feeling fueled.

Quick Summary

Increase energy on a low-carb plan by focusing on calorie-dense healthy fats, choosing fattier cuts of protein, and strategically using high-fat dairy and liquid calories. Create a meal plan with rich, satisfying foods to meet your daily needs.

Key Points

  • Prioritize Healthy Fats: Focus on incorporating high-calorie, low-carb sources like avocados, nuts, seeds, and quality oils into your meals.

  • Choose Fattier Proteins: Opt for fatty cuts of meat and fish, such as salmon, ribeye, and chicken thighs with skin, to increase calorie intake easily.

  • Utilize Liquid Calories: Use liquid options like low-carb protein shakes with added cream or MCT oil to boost calories without feeling overly full.

  • Incorporate Full-Fat Dairy: Add full-fat cheeses, heavy cream, and butter to your cooking and beverages for a significant and tasty calorie bump.

  • Strategize Your Snacks: Keep nutrient-dense, high-calorie snacks like cheese, nuts, and dark chocolate readily available to fill in calorie gaps between meals.

Understanding Calorie Density on a Low-Carb Diet

When transitioning to a low-carb diet, many people experience a natural decrease in appetite. This can be a benefit for weight loss but can become a challenge if you need to maintain or gain weight, or simply feel more energized. The solution lies in shifting your focus from high-volume, low-calorie foods to high-calorie, low-carb foods that are dense in nutrients. Carbohydrates offer four calories per gram, while protein provides four and fats offer a concentrated nine calories per gram. By adjusting your macronutrient balance to include more healthy fats and sufficient protein, you can efficiently increase your total calorie intake without relying on carbs.

The Role of Fats and Proteins in Boosting Calories

Healthy Fats: Healthy fats are the cornerstone of a calorie-rich, low-carb diet. They are the most energy-dense macronutrient and are crucial for hormone production, vitamin absorption, and satiety. You should incorporate a variety of fat sources into your daily meals.

  • Cooking Oils: Use high-quality oils like olive oil, coconut oil, and avocado oil for cooking and dressing salads. Drizzling extra oil on vegetables or meats can significantly boost calories.
  • Avocados: This fruit is packed with monounsaturated fats and fiber. Add it to salads, smoothies, or mash it for a rich, calorie-dense guacamole.
  • Nuts and Seeds: Almonds, walnuts, macadamia nuts, chia seeds, and flaxseeds are excellent sources of fat, protein, and fiber. They make for a convenient snack or can be added to salads and toppings.
  • Full-Fat Dairy: Heavy cream, butter, and full-fat cheeses are loaded with fat and flavor. Add cream to your coffee, melt cheese on your meals, or cook with butter.

Protein Powerhouses: Protein is vital for muscle maintenance and repair. While lean proteins are great, choosing fattier cuts can help increase your calorie count.

  • Fatty Cuts of Meat: Opt for ribeye steak, pork belly, or chicken thighs with the skin on instead of leaner cuts. These options naturally have a higher fat content.
  • Fatty Fish: Fish like salmon, mackerel, and sardines are rich in heart-healthy omega-3 fatty acids and are great for boosting calories.
  • Eggs: Eggs are incredibly versatile and nutrient-dense. Incorporate multiple eggs into your breakfast, make a frittata, or have hard-boiled eggs as a snack.

Calorie-Dense Low-Carb Foods

Beyond just fats and protein sources, certain whole foods provide a significant number of calories while keeping your carb count low.

  • Nut Butters: Almond butter and peanut butter are fantastic options for snacks. Pair with celery sticks or add to a low-carb smoothie.
  • Full-Fat Greek Yogurt: Unsweetened, full-fat Greek yogurt is a creamy, protein-rich base that can be topped with nuts and seeds.
  • Olives: Olives are a healthy fat source that can be added to salads or eaten as a snack.
  • Dark Chocolate: For a delicious, high-calorie treat, choose dark chocolate with a high cocoa percentage (85% or higher).

Comparison of Low-Carb Calorie Sources

Food Item Calories (approx. per 100g) Key Macronutrient Best Use Case
Avocado 160 kcal Healthy Fats Salads, smoothies, toppings
Macadamia Nuts 718 kcal Healthy Fats Snacking, keto baking
Ribeye Steak 271 kcal Protein, Fats Main meal protein source
Olive Oil 884 kcal Healthy Fats Cooking, dressings, drizzling
Salmon (Sockeye) 208 kcal Protein, Omega-3 Fats Main meal protein source
Heavy Cream 340 kcal Healthy Fats Sauces, coffee, desserts
Butter 717 kcal Healthy Fats Cooking, spreading

Practical Strategies for Increasing Calorie Intake

To ensure you meet your daily calorie goals, integrate these strategies into your routine:

  1. Increase Meal Frequency: Instead of three large meals, try eating four or five smaller, more frequent meals. This can make it easier to consume enough calories throughout the day.
  2. Use Liquid Calories: When chewing feels like too much effort, liquid calories can be a lifesaver. Low-carb protein shakes with added MCT oil, avocado, or heavy cream are an easy way to pack in calories without feeling overly stuffed.
  3. Add Fats to Everything: This is a simple but effective rule. Add a knob of butter to your steamed vegetables, a spoonful of olive oil to your salad dressing, or some heavy cream to your soup or coffee.
  4. Snack Strategically: Keep high-calorie, low-carb snacks on hand. Nuts, cheese cubes, or beef jerky can provide a quick and easy calorie boost between meals.

Meal Planning for Higher Calories

Effective meal planning is essential to consistently meet your calorie needs. Planning your meals and snacks in advance helps prevent you from falling short on calories.

  • Breakfast: Start the day strong with a high-calorie breakfast. Scrambled eggs cooked in butter with cheese and avocado slices is a great option.
  • Lunch: Pack a salad with plenty of added fats. Think grilled chicken, salmon, or steak over leafy greens with a generous drizzle of olive oil, topped with nuts and feta cheese.
  • Dinner: End the day with a satisfying, high-calorie dinner. Consider baked salmon with a creamy dill sauce and roasted Brussels sprouts cooked in olive oil.

Conclusion

Getting enough calories on a low-carb diet is entirely achievable by making smart food choices that prioritize healthy fats and proteins. By incorporating energy-dense foods like avocados, fatty fish, nuts, and full-fat dairy, and by using simple strategies like adding extra fats to your meals, you can maintain your energy levels and meet your nutritional goals. Planning is key, and with a little effort, you can create delicious, satisfying meals that keep you properly fueled without relying on carbohydrates. Experiment with different high-calorie, low-carb foods to discover what you enjoy most while supporting your overall health and well-being.
