In my quest to lose a few pounds to get ready for another marathon, I’ve been watching and studying many different diets. Although there are many varieties and methods of dieting, all of them seem to agree that it must be a lifestyle (permanent) change and not just a temporary change. Most people who do not understand this will get into a cycle of Yo-Yo dieting and will often end up with an overall weight gain than a loss. Bad dieting will result in a weight GAIN and not a weight LOSS! 
Many of us are coming out of the season of fasting during Lent. Some have given up shopping, media, food groups, etc. The temptation is to get back to those things we once used to do before with vengeance! And the result is that we find ourselves spiritually fat and sluggish! Our last state might be worse than our first – before the fast!
Don’t waste your Lent. Do things in moderation. Proverbs 25:16, If you have found honey, eat only enough for you, lest you have your fill of it and vomit it.” 
Perhaps certain things should be cut out of our lives permanently even if they are not bad in and of themselves. Certain things should have boundaries around them such as time-limits and intervals. Then, certain things should be added (such as reading, prayer, walking, fasting) to curb our appetite for things. 
Go for permanent changes to match your inside to what God has robed with – spotless and holy. 
Philippians 2:12, “work out your own salvation with fear and trembling, ¹³ for it is God who works in you, both to will and to work for his good pleasure.”
