Aggressive Methods to Lose 20 kg in 2 Weeks

Very Low Calorie Diet
Consuming only 500-800 calories per day from high protein meal replacements and non-starchy veggies. Use under medical guidance only.
Extended Water Fasting
Abstaining from all food and caloric beverages for periods up to 7-14 days to achieve massive calorie deficit. Supervision is vital.
Ketogenic Diet
Ultra low carb, high fat ketogenic diet keeps the body in fat burning mode. Pair with intermittent fasting for accelerated results.
Juice Cleanse
Consuming only fresh vegetable and fruit juices for nutrients while eliminating solid foods. Allows very low calorie intake.
Extreme Calorie Restriction
Eating tiny portions of plain foods like boiled chicken and raw veggies to create up to 1500+ calorie deficits.
Diuretics and Laxatives (Not Recommended)
Strictly for short-term water weight loss only. Depletes electrolytes dangerously and causes dehydration. Do not use except under the direction of a physician.
The more extreme the calorie restriction, the faster the weight loss but also higher likelihood of adverse effects.
