This is a commonsense approach to a healthy way to lose weight and the science of it. The program I use in clinic is based on 1 replacement meal, changing the mindset towards long term healthy habits, cooking and eating real healthy foods, this is often combined with herbs, supplements, a journal and a detox program. I use the Body composition Machine to monitor progress combined with regular blood tests from your Doctor. As stated in the article it’s best done under the supervision of a health care professional.
Strongly suggest only do these long term programs if you are committed to the process as they range from 3 to 6 to 12 months commitment. However always go at your pace and budget.
