Diet and food supplements are a million dollars business in the United States of America. People eat everything that they think would make them look good. I believe everything must be balance. God gave us this life and we must take care of it. We must love ourselves unselfishly by taking care of our bodies for His honor and glory. It's a grief, a problem, a weight that they carried in their minds; but to some, it's something they don't worry at anytime. Job said; "Oh that my grief were throughly weighed, and my calamity laid in the balances together!" (Job 6:2 KJV)
It would be nice if people with problems in diet will consider what Job said; "A false balance is abomination to the Lord : but a just weight is his delight." (Proverbs 11:1 KJV)
