Yes! Feel proud that your taking positive steps to 1) improve your health 2) improve your physical abilities 3) improve your energy levels & if your anything like me improve your self confidence, esteem and make you feel sexier & more vibrant again. All of mine went for a bit of a wander when I started piling on the weight!
Try & focus on 28 days at a time. Each weigh in is 1/4 of the way to goal! By the time it cones around & you are seeing your body shape adjusting to the diet you will probably feel motivated to extend the goal & if not take 2 weeks out to do refeed & week off & then you might feel up to doing another 4 week stint?
Take pics at the start. I'm only 12 days in & already I can start seeing a difference in my shape. Look at before & after pics on here to help focus you on bad days & keep busy doing things to avoid boredom.
Eat at regular times, drink tonnes of water & follow the plan to the letter. Each time you avoid a possible danger zone like family mealtimes, social functions etc think of it as a battle overcome & see yourself as stronger. I personally like to imagine those who expect me to fail having to eat their big fat words when I get to my goal "doing another silly diet" as they put it!
Cone on here anytime you need support, often you will find something that helps & even just reading stuff helps to pass time & before you know it the feelings of lacking will power will be as Gloria Gaynor once sang.......turned around & out that door! You will survive!!! :0)
Keep at it, for you!!!
