weight dilemma

I am always concerned with my weight. I love all the wrong foods and I hate to move --- bad combo. I have joined the gym--good thing. I am trying to watch my food size-portions and intake -- hard to do. I know I cannot ignore this any longer and must make a major lifestyle change. I want with all my heart not just to lose weight but to be healthy. God please help me to make the right choices and give me grace and strength to persue my new exercise career. Marilyn in motion can be fun!
