I watched the video and I thought there was some very poor advice. All weight loss strategies are not equal. Weight loss is only one bio marker of many that you should target. There are plans where you may lose a lot of weight but will lead you to an early grave although you may save money on a skinnier casket.
First and foremost what do the studies suggest is best for reversing heart disease or minimizing the risk of dementia and cancer? What about auto immune diseases and kidney function. They called these the disease of Kings. We know there are poorer countries whose elderly live substantially longer after age 65 and have virtually no heart disease and cancer until their societies adopt the western diet and lifestyle. Same for rheumatoid arthritis and diabetes.
You do not have to spend a dime as there are

For starters I would recommend checking out this video by Dr. Gregor who has been on PBS and has written several best sellers.
