In my 16 years as a dietitian specializing in medical nutrition therapy, I’ve worked with countless individuals navigating complex health challenges – from obesity and diabetes to PCOS and disordered eating. One common thread in these conversations is the allure of low-carbohydrate (low-carb) and very low-carbohydrate diets (VLCDs), often branded under various labels like ketogenic or low-carb intermittent fasting (LCIF). These dietary approaches have surged in popularity due to their potential for rapid weight loss and blood sugar management. But before anyone jumps on the low-carb bandwagon, it’s essential to understand the nuances and long-term implications of these dietary choices.
Looking Beyond the Hype of Low-Carb Diets
Most people view low-carb and VLCDs as a shortcut to achieving their health goals – a quick fix that promises a leaner body and better metabolic health. What is often overlooked is the sustainability and overall impact on one’s lifestyle and relationship with food. The typical perception is that carbohydrates are the enemy, a mindset reinforced by flashy before-and-after transformations and viral success stories. In this blog article, let’s peel back the layers and take a pragmatic, empathetic look at how these diets truly function and who they might actually benefit.
The Physiology of Carbohydrate Restriction
Low-carb and VLCDs operate on a simple principle: restricting carbohydrates reduces insulin spikes and promotes the utilization of fat as a primary energy source. This shift can be beneficial for those with insulin resistance, such as individuals with type 2 diabetes or PCOS, where blood sugar management is key. The reduction in carbohydrate intake forces the body into a state of ketosis (in VLCDs), where fat is metabolized into ketones for energy. While this metabolic shift can indeed result in weight loss and improved glycemic control, it’s not without trade-offs.
What About Sustainability and Quality of Life?
The true challenge of low-carb and VLCDs lies in their long-term sustainability. How many people can realistically avoid rice, bread, pasta, and fruits indefinitely? The initial enthusiasm often wanes as cravings for more diverse meals set in, leading to cycles of restriction and bingeing. This pattern can be particularly damaging for those with a history of disordered eating, as it reinforces an all-or-nothing mindset.
In my experience, the most successful approach to nutrition for managing lifestyle diseases is not just about short-term gains but cultivating a sustainable, balanced relationship with food. For many, this means embracing moderate carbohydrate consumption, focusing on high-quality sources like whole grains, fruits, and vegetables rather than refined and processed options.
How I Teach My Clients to Embrace a Sustainable Low-Carb Diet
When needed, I guide my clients to adopt a low-carb lifestyle that lasts by focusing on balanced nutrition, enjoyable meal plans, and practical strategies that fit their busy lives.
- Mindful Carbohydrate Inclusion: Instead of cutting out carbs completely, prioritize those that offer high nutritional value – fiber-rich vegetables, legumes, and whole grains. These foods not only support metabolic health but also contribute to long-term satiety and gut health.
- Balance, Not Extremes: Pair carbohydrates with proteins and healthy fats to moderate blood sugar levels and prevent energy crashes. For instance, a balanced plate might include grilled tuna, brown rice and sauteed leafy vegetables, and a side of low glycemic index fruit such as orange.
- Listen to Your Body: One-size-fits-all solutions rarely work. Observe how different carbohydrate sources affect your energy, mood, and satiety. Personalized nutrition is key to finding what works for you in the long run.
- Flexible Frameworks: Adopt an 80/20 approach where 80% of your meals follow structured, nutrient-dense guidelines, and 20% allow for flexibility. This strategy reduces the psychological burden of restriction and supports better adherence over time.
- Support Over Self-Sufficiency: Engage with a dietitian who can help tailor your approach based on your unique health status, preferences, and goals. Guidance can be invaluable in navigating the complexities of nutritional science and staying on track.

Final Thoughts
Low-carb and very low-carb diets have their place, particularly for those managing specific conditions like insulin resistance and type 2 diabetes. However, they should not be seen as the universal answer to health and weight management. The goal is not just to follow the trend but to build a sustainable lifestyle that respects your body’s needs, promotes a positive relationship with food, and supports your long-term well-being. As a dietitian and nutrition coach, I advocate for balance – where science meets practical, real-life application.
A diet that works is not just one you can follow for weeks but one you can live with for years, nurturing not just your body, but your entire self.
