Very Low-Calorie Ketogenic Diet (VLCKD) is a modified keto diet plan where the total calorie intake per day would be around 800Kcal. The carbohydrates are under 30g-50g a day. The fats are kept at 10g a day and the protein requirements of the body are met at a recommended rate of 0.8-1g/kg as per the ideal body weight. The diet even satisfies the daily requirements for vitamins, minerals, and trace elements.

When you follow this low-calorie diet, you'll go into controlled ketosis, forcing your body to use fat reserves as its source of energy while maintaining muscle mass. As a result, you will lose weight fast without hunger and feel energized. To avoid complications, a low-calorie keto diet should only be performed under medical supervision.

Differences between the VLCKD and the normal keto diet

In regards to tackling obesity, VLCKDs have unquestionably proven to be an effective tool. Among the benefits they have demonstrated are improvements in body composition, metabolic profile, inflammation, and oxidative stress. However, it's very important to understand the differences between a regular keto diet and VLCKD.

For your convenience, we have simplified the differences.


Regular Keto Diet


(the ProGen Method)

Time required to enter ketosis

15 days to one month

At ProGen, you enter ketosis in 3 days

Health consequences during the diet

Due to high saturated fat levels, cholesterol levels might increase leading to a risk of heart diseases.

The fats are regulated at 10g a day and cholesterol levels of the body decrease in VLCKD

Muscle maintenance

Muscle loss occurs due to low protein intake or poor quality protein intake.

Muscle mass is maintained or even improved due to adequate protein intake of high biological value (1g/kg ideal body weight)

Weight regain

High risk of regaining the lost weight once out of the diet.

Maintenance of lost weight due to genetic metabolic adaptation.

Electrolyte imbalance

During ketosis your body throws out a lot of water causing electrolyte imbalance.

It is regulated by ProGen supplements given on a diet recommended by our specialised doctors.

Vitamin deficiencies

Very common since few food groups are restricted

ProGen provides good quality super vitamin and mineral supplements which meet the requirement of vital minerals and minerals while on ketosis.
