Low Carb Diet

Various high-protein, low carb diet plans have become popular over the last few years and you’ve probably heard about at least some of them.

There’s the Atkins diet, which is a four-phase plan that starts with low carb intake and gradually adds in more carbs as you progress. Then there’s the paleo diet, which emphasizes whole foods and avoids processed products that include grains, legumes and dairy. You may also recognize the low-glycemic index (GI) diet, which focuses on foods with low glycemic index to prevent rapid spikes in blood sugar. And finally, you probably know about the keto diet, a low-carb, high-fat approach to eating that puts your body in a metabolic state called ketosis to burn fat for fuel.

Low carb diets range from moderately low-carb to very low-carb. Why has this style of eating become so popular over the past few years? Scientific studies on low carb diets suggest that they may support weight loss, improved sugar control and better management of certain health conditions.1 And the range of delicious low-carb snacks and low-carb meal recipes available today makes it easier than ever to try.

Explore if the low carb diet is right for you including potential health benefits, recent scientific studies on low carb diets and tasty low-carb recipes you can try today.

What Is a Low Carb Diet?

A high-protein, low carb diet plan restricts the intake of carbohydrates, primarily found in grains, starchy vegetables, fruits and sugary products. The goal of a low carb diet is to reduce the consumption of carbohydrates, especially those with a high glycemic index, and replace them with other macronutrients, such as protein and healthy fats. The specific carbohydrate intake can vary, but it typically involves significantly fewer carbs than the average Western diet.

Low Carb Diet Benefits

There are many benefits to the low carb diet which has contributed to its lasting popularity. Some top benefits of the low carb diet plans include:

The Science-Backed Benefits of a Low Carb Diet

Learn more about the science-backed benefits of a low carb diet.

A recent scientific study on the effects of low carb diets suggests that the high-fat requirements do not increase the risk of developing heart-related health issues.6 In fact, this type of diet could potentially lower the likelihood of developing heart and insulin-related conditions, especially due to the associated weight loss.

Another scientific study7 points to the role of low carb diets in the prevention and treatment of progressive cognitive and functional decline. In a 12-week research program, 25 participants living with dementia improved their daily function and quality of life while on a keto diet. This low-carb, high-fat approach to eating holds promise in the treatment of certain cognitive health issues.

And finally, a ketogenetic diet can lead to higher physical functioning and lower fatigue, according to a research study8 on patients recovering from serious health conditions. Participants following the keto diet (high-protein, low-carb) also had better emotional functioning and improved sleep, compared to those following a healthy standard diet and a low carb diet (not as low-carb as keto).

Are all carbs bad when following a low carb diet?

No, not all carbs are bad. Carbohydrates are classified into two categories: simple carbs and complex carbs. A low carb diet encourages reducing simple carbs while allowing for some complex carbs. Simple carbs include sugary foods (like candy and soda), refined grains (like white bread and pasta) and high-sugar fruits (like grapes and watermelon). Complex carbs include non-starchy vegetables (like leafy greens and broccoli), some whole grains in moderation (like quinoa and barley) and legumes in limited amounts.

How long can I follow the keto diet?

It can be safe for many people but may not be suitable for those with certain medical conditions. It’s essential to consult with a healthcare professional before starting a low carb diet, especially if you have health concerns or are pregnant or breastfeeding. If you’re an athlete, you may need to adjust your carb intake to sustain your energy levels. And at first, you may feel temporary side effects like the keto flu. Sustainability and balanced nutrition are key; emphasize whole foods, fiber and essential nutrients for long-term health.

Will I feel hungry on a low carb diet?

Initially, you may experience hunger and cravings when transitioning to a low carb diet. This is partly due to the body’s adjustment to lower carbohydrate intake, which can lead to reduced blood sugar and increased appetite. However, many people find that these feelings of hunger diminish over time. Low carb diets tend to provide better satiety due to increased protein and fat intake, which helps control appetite. Additionally, stabilizing blood sugar levels and reducing reliance on quick-burning carbohydrates can lead to more sustained energy and decreased cravings.

Can I exercise on a low carb diet?

Yes, you can and should exercise on a low carb diet. Physical activity is an essential part of overall health and well-being. When starting a low carb diet, you might experience temporary adjustments in energy levels due to the shift in fuel sources. However, as your body adapts, you may find you have more stable energy levels for exercise. Low carb diets can support weight loss and improved metabolic health, making exercise even more beneficial.

How long does it take to see results from a low carb diet?

The time it takes to see noticeable results from a low carb diet is different for everybody. You may lose weight relatively quickly in the first few weeks. You may also notice improvements in your blood sugar control, which translates into appetite reduction and decreased cravings. Long-term changes in overall health may take several months to become more evident. Be patient with yourself and try to stay consistent over time to see lasting results.

What’s the best low carb diet?

The “best” low carb diet is subjective and depends on your goals and preferences. The ketogenic diet can be a great way to support healthy weight maintenance and potential therapeutic benefits, while the Atkins diet provides a phased approach for structured progression. The paleo diet focuses on whole, unprocessed foods, the Mediterranean diet includes healthy carbs and fats and the low-carb high-fat (LCHF) diet offers flexibility. South Beach diet phases provide a gradual reintroduction of carbs. The best choice is one that aligns with your health objectives, dietary preferences and lifestyle.

Can vegetarians follow a low carb diet?

Yes. While many low carb diets emphasize animal proteins, you can adapt the approach by focusing on plant-based sources of protein and healthy fats. Include foods like tofu, tempeh, seitan, nuts, seeds, eggs and low-carb dairy alternatives. Include non-starchy vegetables as the basis of your meals to provide fiber and essential nutrients. Avocado, coconut oil and olive oil are excellent sources of healthy fats. Limit or avoid high-carb vegetarian foods like grains, starchy vegetables and sugary fruits. To get the most out of your low-carb vegetarian diet, plan carefully and monitor your nutrient intake.

What are low-carb foods?

Low-carb foods include non-starchy vegetables like leafy greens, broccoli, cauliflower, zucchini and bell peppers. For protein, reach for lean meats like chicken, turkey, beef and fish. Eggs are carb-free and a nutrient powerhouse. Nuts and seeds, such as almonds, walnuts, chia seeds and flaxseeds, offer healthy fats, protein and fiber. Certain dairy products like Greek yogurt and cheese are low in carbs but provide protein and calcium. Healthy fats from avocado, olive oil, coconut oil and butter are low-carb energy sources. Lastly, while most fruits contain carbs, berries like strawberries, blueberries and raspberries are lower in carbs and rich in health-promoting antioxidants.
