Michael Collins, founder of SugarAddiction.com and Board Chairman of Food Addiction Institute, has been completely sugar-free for over 30 years and has worked closely with others to help them regain lives ravaged by this addictive product. Mike has been in recovery from substance-use disorder for over 34 years and can speak on recovery topics separate from sugar. He raised two children sugar-free from the womb to over six years old - when they only had sugar once a month for their entire childhood. His book, which was rated #1 in Healthy Living on Amazon, will be available to your audience for free for the day of the interview.
