When you hit a plateau in your fitness goals, take a step back and evaluate how far you have come. Give yourself a pat on the back based on the progress you have made. Many people are too hard on themselves and fail to see the good, in the bad. Take a step back, re-evaluate your goals, kick your focus into high-gear and don't let your foot off the gas.
Targeting excess body weight means you need to eat nutritious food, in the right quantity, for your height, age, and weight. This is a juggling act and will continually need to be altered. Unfortunately, people do race, and diet has come to mean deprivation. Deprivation is unhealthy and will never lead to a healthy sustainable weight loss. Use and follow this acronym for diet.
