Prayer For Self-Control Over Gluttony

Heavenly Father I come to You to pray for self-control, which is one of the precious ‘fruits-of-the-Spirit’. Lord, I am overweight and know that I eat more that I should, which demonstrates that I am lacking in this beautiful gift of self-control.
Lord, I know in my heart that there is no satisfaction in food, (or anything else for that matter), and that my gluttony only exposes the idolatrous nature in me, for which I repent. I am asking that in the power of Your Holy Spirit, You would help me to become a more self-controlled person in my eating habits. 
Lord, I know that I am not able to live a godly, self-controlled life in my own strength but You have said in Your Word that You have provided all I need to live godly in Christ Jesus. Help me I pray, to appropriate all that I have in Christ, to walk in spirit and truth, to mortify this appetite for food and to depend on You to deliver me from this bondage to sin.
I pray that You finish the good work in me that You started when I first believed in the Lord Jesus as my Saviour, and I will give You all the praise and glory. In Jesus' name,
