Offer to help someone else! Whether it be cleaning, charity work, or just walking with them, studies show that you are more likely to stay motivated if you have obligated yourself to do so. It also doesn't hurt to have that person by your side, showing you encouragement and solidarity in your fight.
While on your weight loss journey, it is important to be patient. It's proven that those who were patient and took the weight off slowly are the ones who will keep it off in the long-run. Losing just one or two pounds a week may not sound like much, but if you want to keep it off, that is the way to go.
Reward yourself with a treat. If you have been doing a great job of sticking to your diet and exercising regularly, treat yourself. This can mean buying yourself something or maybe even ordering a slice of cheese cake for dessert. Treat yourself once a week or so, just don't go overboard with it.
In order to lose weight and keep it off you need to make dining pleasurable. Besides eating delicious, healthy food, you need to create a relaxing eating experience. Turn the television off and sit at the dining room or kitchen table. Eat with other family members. Use regular plates and flatware, even if you are having pizza. Take your time eating and your body will learn that there is more to meals than the volume of food you eat.
