Dear Beautiful, and You are beautiful to our Lord.
There are instructions for eating in Leviticus 11, Daniel 1:8-, (may be others but I don't have a Concordance here) that may be helpful to you for eating. I had to change my eating habits since I have a chronic vascular disease and eat mostly fruits, vegetables, grains, nuts, yogurt, etc. Plus I exercise every day with warm up, cardio, aerobics, stretching and cool down. I drink lots of water to flush my system. And I think on positive thoughts, help my family, and love my Lord. Walking and bicycling are great for trimming down plus you can enjoy nature and all the beauty of the Lord. I ask and pray in Jesus' name for your prayer request. Amen and Amen.
