Are you struggling to shed those extra kilos or maintain a healthy weight? A low carb diet might be the key to unlocking your weight loss potential and improving your overall health.
In this article, we’ll get into the benefits of low carbohydrate diets while arming you with the knowledge to make this lifestyle work for you. But first, let’s answer the question: what is a low carb diet?
Key Takeaways
- Low carb diets emphasise proteins, fats and vegetables for potential weight loss and health benefits.
- Smart swaps such as cauliflower rice or zucchini noodles can help maintain a low carb diet while still enjoying favourite dishes.
- A healthcare professional or registered dietitian should be consulted before making any dietary changes to understand the facts and risks of a low carb lifestyle.
What is a Low Carb Diet
Low carb diet is a type of diet that limits the amount of carbohydrates being consumed. Food with high carbohydrate content is replaced with food containing higher amounts of protein and fat.
Due to the nature of this diet, it is deemed to be beneficial by experts in the nutrition industry. Some of the benefits of doing a low carbohydrate diet are aiding weight loss, improving blood sugar levels, and regulating triglyceride levels.
Understanding Carbohydrates
Carbohydrates are a macronutrient found in various food groups, supplying energy to the body. They can be categorised into simple and complex varieties, each with a different impact on blood sugar levels and insulin response. Carbohydrates play a significant role in the body’s overall metabolism, serving as an energy source, controlling blood glucose and insulin metabolism, providing stored energy, preserving muscle, and promoting digestive health.
Maintaining a balanced carbohydrate intake is key for a successful low carb diet.
The Principle Behind Low Carb Eating
The fundamental concept behind a low carb diet is restricting carbohydrate intake, stimulating fatty acid oxidation, and maintaining steady glycemic levels. By eating fewer carbs, the body shifts from using glucose as its primary energy source to burning stored fat for fuel. Prioritising protein intake in a low carb diet is advantageous for weight loss and muscle maintenance.
Variations of Low Carb Diets
There are various low carb diets, each with its level of carbohydrate restriction. Some popular low carbohydrate diets include the Atkins diet, which allows for unlimited fat and protein consumption while limiting carbohydrate intake for weight loss and improved health.
On the other hand, the ketogenic diet, also known as the “keto” diet, involves restricting carbohydrate intake to a very low level, typically less than 50 grams per day (Harvard School of Public Health 2018).
The low-carb, high-fat (LCHF) diet focuses on reducing carbohydrate intake and replacing it with healthy fats, emphasising low-carb and high-fat foods, which is a different approach compared to a low fat diet.
What Foods to Favour and Avoid on a Low Carb Diet
To achieve optimal results on a low carb diet, understanding which foods to prioritise and avoid is beneficial. Understanding the carbohydrate content of various foods will help you manage your daily intake and stay within the recommended limits.
Incorporating foods like non-starchy vegetables, lean proteins, and healthy fats into your diet will help you eat fewer carbs while still keeping you full. On the other hand, avoiding carbohydrate-rich foods such as sugar, grains, and starchy vegetables is beneficial to your weight loss goals and overall health.
Embracing Low Carbohydrate Foods
To successfully follow a low carb diet, focus on consuming:
- Healthy low carb food like non-starchy vegetables such as leafy greens, broccoli, capsicum, cauliflower, zucchini, and cucumbers
- Lean proteins such as poultry, fish, eggs, and tofu
- Healthy fats like avocados, nuts, seeds, olive oil, and fatty fish like salmon
Steering Clear of High Carb Culprits
When following this type of diet, it is imperative to avoid foods high in added sugar and refined carbohydrates. Refined carbs include sweets, pastas, bread, and processed foods. Steering clear of these high carb foods will help you maintain a low carb lifestyle and support weight loss and improved health.
Smart Swaps for Common Carbs
To make your low carb diet more sustainable, consider replacing common carbohydrate-rich foods with low carb alternatives. For example, use cauliflower rice instead of traditional rice, lettuce wraps in place of bread or tortillas, and zucchini noodles as a substitute for pasta.
What Are the Health Advantages of Reducing Carb Intake
A low carb diet offers numerous health benefits beyond weight loss, including improved blood sugar control, heart health, and even the potential to reverse type 2 diabetes. You will lose weight and be setting yourself up for success in achieving your health goals by reducing carbohydrate intake and focusing on nutrient-dense, whole foods.
However, a peer review conducted by Landry et. al. (2022) showed that low carbohydrate diets are beneficial in the short term with diminishing benefits over time. A balanced diet is shown to be better in weight control compared to a very low carbohydrate diet in the long run.
The following sections will detail the health advantages of a low carb diet, including its support for weight loss maintenance, regulating blood sugar levels, and boosting heart health.
1. Weight Loss Maintenance
One of the primary benefits of a low carb diet is its ability to facilitate weight loss and maintain a healthy weight. The consumption of low carb foods puts the body in a state where it begins to use its stored fat as an energy source. This process results in weight loss. Low carb diets also affect appetite, reducing hunger and cravings, which further contributes to weight loss.
2. Regulate Blood Sugar Levels
Reducing carb intake can have a significant impact on blood sugar levels and insulin resistance, which is particularly beneficial for those with diabetes. Research by Snorgaard et. al. (2017) published in the BMJ Open Diabetes Research & Care Journal has shown that “low to moderate carbohydrate diets have greater glucose-lowering effect compared with high-carbohydrate diets”. This concludes that blood sugar levels can be regulated by altering the amount of carbohydrate intake.
3. Boost Heart Health
A low carb diet can have several benefits for heart health, including:
- Increasing good cholesterol levels (HDL cholesterol levels)
- Decreasing triglyceride levels
This is supported by the review of “Efficacy of low carbohydrate diet for type 2 diabetes mellitus management: A systematic review and meta-analysis of randomised controlled trials” conducted by Meng et. al. in 2017. A study by Chawla et. al. (2020) also found similar results with an added finding that “improvements in LDL cholesterol favoured the low-fat diets”.
