We all are faced with temptation in several areas of our lives on a daily basis. We must try to resist.
Old Way Of Thinking/Old Excuse: "If I deprive myself now, I'll just eat more later".
New Way Of Thinking: "I am making a choice, not a sacrifice"
Instead of thinking about 'depriving' yourself, try to think about choosing, it is your choice, it is up to you, as to what you eat. Before giving into a craving, put it on the back burner; wait until you have fit in a workout or finished your dinner. In other words, wait to indulge. Try it and see, your desire to do so may decrease.
