What Is a Very Low-Calorie Ketogenic Diet?
The Very Low-Calorie Ketogenic Diet (VLCKD) is a scientifically designed, short-term nutritional approach intended to promote rapid and sustainable weight loss. It combines two powerful strategies: significant caloric restriction (800–1200 kcal/day) and a drastic reduction in daily carbohydrate intake, all while maintaining sufficient protein intake to minimise lean muscle loss and suppress hunger.
Unlike many low-calorie plans, the VLCKD does not neglect dietary fibre. In fact, it encourages a higher-than-average fibre intake, supporting gut health and helping regulate digestion and appetite. Moderate amounts of healthy fats are also included—not only because they’re essential for hormonal and cognitive function, but also because they contribute to satiety and overall wellbeing.
Your daily calorie deficit on the VLCKD will depend on your current weight, but typically ranges from 1200 to 2000 kcal. This consistent energy deficit enables most individuals to lose around 10% of their starting body weight in approximately six weeks.
Why Choose the VLCKD – and What Makes It So Effective?
The success of the VLCKD lies in its metabolic impact. By significantly reducing carbohydrate intake, your body transitions into a state known as ketosis —usually within 2 to 4 days. In ketosis, fat becomes the primary fuel source, and ketones replace glucose as the main energy supply, particularly for the brain.
This change brings several important benefits beyond just fat loss:
- Appetite suppression: Ketosis naturally reduces hunger, making it easier to stick to the plan without constant cravings.
- Minimise muscle loss: A key benefit of adequate protein intake is that it minimises your muscle mass, even as your body sheds fat.
- Improved blood sugar regulation: With fewer blood sugar fluctuations, many people experience improved mood and reduced irritability.
- Better sleep and cognitive clarity: Ketones provide a stable and efficient energy source for the brain, often leading to more restful sleep and mental sharpness.
The VLCKD is more than just a diet—it’s a powerful reset for your metabolism, energy levels, and long-term health. Supported by expert-designed meal plans and convenient, nutritionally balanced products from Dr Eva’s Clinics, it is both achievable and sustainable
