I’m 7 weeks into the Intensive Level and I have lost 13.6kg! I have never EVER lasted this long, felt this energetic, lost so much and felt so motivated.
There is loads of self-talk (mindfulness) ALL DAY LONG to keep me positive, fight the urges and remind me of why I’m doing this, but it really has flown by and I am looking forward to shedding the next 26kg! It hasn’t taken much thought really, and that has really helped. I buy it, shake it, sip it and this has really helped lead me to success! A positive health outcome from losing weight is that my blood pressure has improved and I’m sleeping more soundly, not to mention that the person staring back at me in the mirror is now looking much happier!Shop All OPTIFAST Products
How does it work?
On the Intensive Level you will replace all 3 meals with OPTIFAST VLCD products. This level provides up to 800 calories per day and is designed for fast weight loss via a metabolic reaction called 'ketosis'. In addition to the 3 OPTIFAST VLCD products, you will also have:
- At least 2 cups of low starch vegetables
- 1 teaspoon of vegetable oil
- 2 litres of water every day
IMPORTANT: Due to the energy restriction of under 800 calories per day, this Level is only to be followed by individuals with a BMI of 30kg/m2 or more, or 27-30kg/m2 with weight related co-morbidities such as diabetes, hypertension, high blood pressure, and high cholesterol. You must speak to your healthcare professional before commencing on the Intensive Level.What is ketosis? See Allowed Foods List
