There is an inextricable link between the mind and body. God desires that they be in balance.
God loves us and wants the best for us!
11 For I know the thoughts that I think toward you, saith the Lord, thoughts of peace, and not of evil, to give you an expected end. Jer 29:11 KJV
We should wish the same for others
In 3 John 1:2 KJV we read...
2 Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth.
...If thou wilt diligently hearken to the voice of the LORD thy GOD, and wilt do that which is right in His sight, and wilt give ear to His commandments, and keep all His statutes, I will put none of these diseases upon thee which I have brought upon the Egyptians: for I AM the LORD that healeth thee.
The 10 commandments in Exodus chapter 20 are for our eternal good.
We are to overcome appetite and sins through the strength of our LORD Jesus Christ. The original diet in the garden of Eden was the best. The LORD GOD is trying to bring us back to a simple diet of fruits, nuts, whole grains, and vegetables, and have us in the best health so that we can be strengthened to proclaim the everlasting gospel message to all the world and be ready for His soon return.
