Strong, Obstinate Brain at Times

I was doing well with weight loss until the other day when I allowed myself to have sugar during a birthday celebration. The 2 days afterwards were hard in terms of managing my brain. One of my thoughts was “I don’t care. I want that (with sugar) again right now!” The thought was very strong. I kept in mind that I needed to be compassionate and loving while at the same time be firm with myself. My strong compelling reason was not strong enough at those moments though. Is that the power of what sugar can do to our brains? Where the desire for dopamine is so high? Is that what was going on? How do those who have kept weight off for years deal with those moments?

Thank you in advance for answering those questions and helping me to learn more about managing my brain during moments when it is in strong, stubborn opposition.
