FitFood was developed by Anri in 2016. The Weight Control Clinic inspired her to start this endeavor. Anri’s FitFood Ready Made Meals (fresh or frozen) are Weight Control Clinic Approved, healthy, delicious, quick, easy and convenient. These meals are ideal if you are very busy or simply just don’t like cooking. ‘Too much of a good thing, is also bad.’ Tehrefore, calories are specified to keep you on track. ‘If anyone told me a few years ago that I would be making food in the future I would definitely not have believed them. I realised our patients were struggling with preparation and I knew I would be able to assist, I then started FitFood Ready Made Meals to help others follow a healthy lifestyle that is convenient and fits into their lifestyle. Now I have become a total foodie and I love it when people enjoy my meals. It is important to know that leading a healthy lifestyle most definitely does not mean eating bland and boring food. So give my meals a try and let me know what you think.’

You are what you eat!’
