Low carbohydrate (low carb) diets have become increasingly popular over the past decade, often promoted for weight loss, blood sugar control, and improved energy levels. But what exactly is a low carb diet, and is it something a dietitian would recommend for everyone? Let’s take a closer look.

What Is a Low Carb Diet?

A low carb diet focuses on reducing the intake of carbohydrates such as bread, pasta, rice, cereals, sugary foods, and some starchy vegetables. Instead, it emphasises higher intakes of protein, healthy fats, and non-starchy vegetables. Common foods include lean meats, fish, eggs, nuts, seeds, dairy, and vegetables like leafy greens, broccoli, and zucchini.

There is no single definition of “low carb.” Some plans moderately reduce carbohydrates, while others—such as ketogenic diets—restrict them quite significantly. The level of carbohydrate restriction can influence how sustainable and appropriate the diet is for different individuals.

Potential Benefits of a Low Carb Diet

For some people, a low carb approach can be beneficial. Research suggests it may help with short-term weight loss, particularly by reducing overall calorie intake and appetite. It can also improve blood sugar control in people with insulin resistance, pre-diabetes, or type 2 diabetes when supervised appropriately.

Some individuals also report improved energy levels and reduced sugar cravings once their diet is better balanced and less reliant on refined carbohydrates.

Is a Low Carb Diet Right for Everyone?

While low carb diets can be helpful for certain people, dietitians do not recommend them universally. Carbohydrates are the body’s preferred energy source and play an important role in gut health, brain function, and physical performance.

Highly restrictive low carb diets may not be suitable for:

• Athletes or highly active individuals

• Pregnant or breastfeeding women

• People with certain medical conditions

• Those with a history of disordered eating

Cutting carbohydrates too aggressively can also lead to nutrient deficiencies, fatigue, constipation, and difficulty maintaining the diet long-term.

What Do Dietitians Recommend?

An accredited dietitian focuses on individualised nutrition advice rather than one-size-fits-all diets. At Melville Wellness Centre, our dietitian works with clients across Melville and the wider Perth area to assess lifestyle, health goals, medical history, and food preferences before recommending any dietary approach.

For many people, a balanced diet that includes quality carbohydrates—such as whole grains, fruits, legumes, and vegetables—alongside protein and healthy fats is both effective and sustainable. In some cases, a moderate reduction in refined carbohydrates may be beneficial without needing to eliminate them altogether.

The Bottom Line

A low carb diet can be a useful tool for some individuals, but it is not suitable or necessary for everyone. The best results come from a personalised approach guided by a qualified dietitian who can ensure nutritional adequacy, safety, and long-term success.
