You are not stupid. You know that you're "supposed to" eat vegetables and fruit and that you're "supposed to" avoid junk food. So why the hell is it so hard to put it into practice?!
Three reasons: Habit, environment and convenience.
If you're unable to hit your health and fitness goal, if you're frustrated with your inability to eat what you're "supposed to" eat, I invite you to join Eating for Wellness. EFW is a four-week group program where we'll focus on building new habits, the key to putting into practice what we know in theory.
You will be surprised what you can achieve when you concentrate your focus over a period of time, supported by a professional (that's me), plus a group of like-minded peers working to achieve their goals.
