If you want to have something you've never had before, you have to be willing to do something you've never done before.
Me working out this morning.
Your weight is not an unchangeable "set point." It's a "settling point" that can be influenced through consistent lifestyle changes. You can reach a sustainable level of body fat where you look and feel athletic. Because muscle is metabolically active, increasing your muscle mass increases your basal metabolic rate, allowing you to burn more energy at rest and giving you more flexibility with your food intake. Through proper meal planning and disciplined training, you can gradually reset your body's "default" weight range to a lower, leaner level.
Care to give it a try?
