Welcome
Glad that you found this forum...it offers good information, support like Buddy groups and challenges and inspirational success stories. Another fan of Ken and Grav, guys who have not only lost significant weight but have kept it off and will freely help you to your goal. They both published their stories on DietDoctor, and you can find more at that website, including this new post from a man who lost 247 pounds and created a well-written blog about his LCHF journey. https://www.dietdoctor.com/the-weig...n-me-a-new-life and the long time low carb fan Larry Diamond. https://www.dietdoctor.com/lchf-is-...your-loved-ones

There is an older thread here about changing habits, some people are successful with the occasional treat to keep them going, but from this discussion you will see most of us on this forum are "Abstainers". It is easier to develop the habit "I never eat sugar or grains" than to once a week have "one cookie" http://forum.lowcarber.org/showthread.php?t=468195 And if you ever do want to read a good overview LCHF book as you see here, many are inspired by Gary Taubes's Why We Get Fat.

Look around the various sub-forums here, many interesting topics. All the best,
