Slender Wonder And How You Can Lose Weight

Slender Wonder is a medical diet program that was implemented in South-Africa +/- 40 years ago by Dr. Jan Botha after years of research done by an Italian doctor, Dr. Simeon.

Slender Wonder is not a diet based on kilojoules but a formula based on the glycemic index of food.

A low GI diet

Together with the Slender Wonder products (shake and tablets) and injections the formula ‘enables’ the body to improve Leptin sensitivity. Leptin is a hormone which is formed in the fat cells that regulates the entire adipose metabolism.

Someone with a normal Leptin sensitivity can eat any amount of food without gaining weight but when the Leptin resistance in the body increases, appetite and ‘hunger’ increases and the metabolism falls resulting in everything eaten is converted into fat and is stored in the body.

When this happens, it will make no difference what diet they follow as weight gain will occur due to Leptin resistance. Leptin sensitivity is normalized with the Slender Wonder program and patients maintain their weight far easier than with any other program.

The Slender Wonder program focuses on restoring the Leptin hormone levels situated in the unwanted abnormal fat cells (found around the hips, tummy, thighs, upper arms and the buttocks). The Slender Wonder products with the prescribed eating plan and the intake of plenty of water helps restore the Leptin hormone thus helping the patient lose a large percentage of weight and fat mass in a short period. Most individuals lose about 7-10 kg within the first month on the Simeon A or Simeon B meal plan.

We’ve seen instances where male individuals have lost 18kg in one month; it all depends on the relationship between total body mass and weight loss mass. Weight loss may be less, especially with insulin resistant patients. By the time you reach the maintenance phase your Leptin levels should be restored preventing you from putting on the weight again as long as you maintain a healthy diet.

The Program

slender wonderOn your first consultation, the doctor will do measurements with a Body Stat machine which will determine the exact percentage of fat, lean body mass, muscle and water in the body as well as determine the basal and active metabolic requirements of an individual patient.

The actual Slender Wonder program works on a medical formula consisting of daily injections, certain dietary programs, protein shakes and well researched supplements to ensure fast and medically safe weight-loss. The system was scientifically proven to ensure only the loss of non-structural “bad” fat and not a reduction in kilograms due to the loss of muscle or water .This is constantly monitored by performing regular Body Stats.

The  Slender Wonder program has 5 phases:

  • Phase 1Stimulation Phase: Starting with daily injections (the doctor will show you exactly how and where to inject yourself daily, or a significant other can inject you daily before 12 noon. The needle is similar to an Insulin needle used by Diabetics) and eat any fatty meals as much as you like for 2 days in order to fill all your fat cells to their maximum while drinking our Wonder/Easy Cleanze tablets and K-L Cleanze.
  • Phase 2Detox Phase: daily injections will continue; drink the Protein Plus Shake once a day in the morning. Eat 300g fruits 3x a day. Start taking all the supplement tablets (except the CLA), and drink 2-3 litres of water daily. Rest as much as possible, do not exercise. This phase continues for 1-3 days.
  • Phase 3Weight Loss Phase: For 4-6 weeks following our Simeon A/B meal plan (provided in the Slender Wonder book), continue the daily injections, and drink all the supplements as well as the CLA tablets. Following the Simeon A/B eating plans without the daily injections will result in starvation, Which is why the injections are so important!
  • Phase 4Stabilization Phase: After you have reached your goal weight, you have to follow the stabilisation-eating plan for 1 month. Eat according to the moderate meal plan every Monday and Thursday. Daily injections are stopped and your doctor will then administer a stabilization injection. Failure in completing the stabilisation month will result in unwanted weight gain.
  • Phase 5Maintenance Phase: No daily injections, supplements are optional. Eat according to the Red, Yellow and Green lists as indicated in your Slender Wonder book. See your doctor every 3 months for a maintenance booster injection. Weigh yourself daily and make an appointment to see your doctor if you start gaining more than 2-3kg. (Duration of this phase: 1 year). (The costs of the last phase will be R750.00 – R850.00)
