Ketogenic VLCD, also known as the active stage, can be divided into three parts:
1. In part one, five ready to eat ‘Protekal’ meals per day are consumed including vegetables and fresh salads. The Protekal meals, as well as supplements are prescribed by one of our doctors. The meals consist of a variety of soups, omelets, purees, oat meals, pancakes, cakes, puddings, mousses, shakes and juices.
The active stage consists of fat and carbohydrate reduction in your diet preserving the protein intake. Increased protein intake triggers certain metabolic changes in the body (boosts metabolic rate), which is manifested by providing necessary energy from your own body fat reserves. Thanks to a low carbohydrate intake hypoinsulinemia (low concentration of insulin in the blood) develops. It causes lipolysis (breaking down fat cells). Fatty acids are oxidized into ketone bodies, which in turn become a source of energy, yet have an anorexic effect – suppress hunger and appetite, and provide cheerfulness and plenty of energy.
Due to the described metabolic changes, the protein diet is characterized by:
• suppression of hunger
• rapid loss of fat tissue and preservation of muscle tissue (due to adequate intake of proteins with high nutritional value).
2. In part two of the active stage, one Protekal meal is replaced with some meat, eggs, fish, or sea food (under doctor’s supervision).
3. In part three of the active stage two Protekal meals are replaced with some meat, eggs, fish or sea food (under the doctor’s supervision).
During the active phase a patient can lose anywhere between 1.5 to 2 kilograms a week, which gives immediate visible results and therefore the percentage of those who quit the diet is very low. During the active stage patients have regular checkups every two weeks and are monitored by the doctor to establish their condition and determine the transition to the next stage.
