Kathy Britz, a 57 year old woman from Plettenberg Bay in the Western Cape lost 34kg on The 28 Day Diet.

Kathy and her friend were each other’s motivation to start this journey. She started on 120kg and is currently weighing 86.7kg.

Sometimes people find it hard to start changing their habits and lifestyle, and make the mind shift to live their best life. If you can find someone to do it with you, it not only helps to keep you motivated; it also helps to keep yourself and each other accountable and increases your likeliness to be successful.

The most difficult part of the plan for Kathy was the beginning. 

According to the self-help book, Psycho Cybernetics by Dr. Maxwell Maltz, habits are formed by completing a task for 21 days in a row.  After twenty-one days of task completion, a habit is formed. A habit may initially be triggered by a goal, but over time that goal becomes less necessary and the habit becomes more automatic.

Kathy overcame the initial hurdles with the help of prayer and developing the mental stamina to persevere.

Losing weight in your teens, 20’s and 30’s may be achieved relatively easily. But weight loss requires more effort as you reach middle age due to aging muscles, hormonal changes and lifestyle changes – to name a few.

Kathy is a true testament that, although difficult, achieving weight loss after 40 is indeed possible if you believe in yourself.

Her advice for anyone considering whether to start with The 28 Day Diet is, “Go for it – it’s absolutely amazing!”

      Dear Lynette,

      Well done so far! Amazing just keep going. Even after the 28 days you can continue to make this a lifestyle but watching your portion sizes and trying your best to keep eating healthy. Should you fall off the bus as they say, just re start the first 4 days as that will be your detox period as the body loses water etc you will feel the centimetres first then the weight drop.
