The first step to doing this is to become aware of your eating patterns. For instance, if you tend to overeat when you're stressed about work, then make adjustments based on this. If you know you tend to overeat when you're overwhelmed, make it a point to keep yourself busy with another activity (even something relaxing like reading or taking a bath) during this time.
Next, focus on making small changes in your lifestyle, not on losing weight. For instance, rather than thinking, "I have to lose 30 pounds," think, "Today I'm going to take a pass on the bread and butter and go for a walk after dinner."
By adding just one or two healthy behaviors to your routine each day, you’re subtly changing your old, weight-sabotaging habits into new healthier ones.
Most importantly, stay positive. Focus on all you have to GAIN from your newfound mindset, rather than all you’re giving up.
