Thanks Mithun for reaching out to the Grokker community. I think one thing you need to settle on is from this point forward it is no longer a diet but a life style change. Exercise is only part of the answer, food is another part of the answer and thirdly, your mind set. Sue Mah has some wonderful videos that are easy to follow. Try the Sugar Reset, Carb Reset and Mindful eating. Team this with some of Chris Mohr videos. Most importantly is that you do this just for you. We are all here to encourage you every step of the way.

Please find three mindfulness programs that you can follow that can help you focus on being happier and healthier:
