10. Find a workout partner.
This is accountability done right. A good workout partner is someone who wants to workout at the same time as you and do a similar workout, and someone whose company you enjoy. Why it works: if you set an appointment with a workout partner, you won't want to miss it. You'll make sure you're there, unlike when you work out by yourself — many people are very tempted just to cancel their workouts if they're a little tired or busy. Also, a workout partner makes the workout a little more fun, and that's always a good thing. If you get a workout partner, you will have a stress-free exercise plan that will compliment your healthy eating perfectly. Try for 3-5 workouts per week, giving yourself plenty of rest time after hard workouts.
11. Allow yourself to cheat.
A strict diet plan is a bad one. If you are severely restricting yourself, and you feel deprived of good foods, you won't last long. Trust me, I've tried it many times. Instead, relax a little bit, giving yourself a cheat meal or two each week, and allowing yourself to cheat a little on special occasions. It's still best if you can go for the healthier foods on special occasions, but don't be too strict.
12. Three-bite rule.
A great way to allow for cheats is the Three-bite rule … basically, if you want a sweet or some other sinful food, don't deny yourself … allow yourself a little indulgence, but just three bites. Allow yourself to enjoy the taste, eat slowly, then move on to healthier foods.
13. Forgive, and move on.
If you make a mistake, or cheat more than you should, don't just give up or beat yourself up. This kind of negative thinking is why people don't stay on diets for long. They binge and then go back to their unhealthy habits. Instead, just forgive yourself for any indulgences, and get back on your healthy eating plan. Look forward, not backward.
14. Get inspired.
Motivation is important … maybe the most important thing. Accountability (mentioned above) is the best motivator … but I'd put inspiration at a close second. Find others who are doing what you want to do, read success stories, read magazines and blogs and books, put up a motivational poster … whatever it takes to get inspired.
