I've tried a lot of ways to motivate myself to lose weight too. I've tried asking friends, but they just drop out of touch. The husband needs to do different stuff, so that motivation is sporadic. Joining exercise classes is exhausting. Finally, I decided to do a combo of those things. This is what worked for me, hopefully some of it can work for you too.
1. I work out at home and count calories. 3FC really helps keep me accountable as these people understand how tedious calorie counting is as well as how well it works! All my friends tell me I'm nuts, and that's fine
2. My husband is a support, but most of the motivation comes from myself. I try to be selfish (which it tough for me), and say that
I deserve this and I'm determined to do it (it helps know exactly what 'it' is).
3. I plan. Plan, plan, plan. I plan my meals, prep my food on Sat or Sun, and I plan my workouts for the week. Sometimes I write it down, but since I've been in a habit for a while, I no longer need to.
4. To ward off cravings, I tell myself not to eat after 8pm (unless I haven' eaten enough during the day, which is rare). I brush my teeth at 8pm so that i'm not tempted to snack after that, and I'll drink tea or water for the rest of the night.
Those are the big things that have helped me on this weight loss journey. through this, I've learned to be patient with myself. No one else will lose the weight for me, and people are in different places in their own weight loss goals. I just keep motivating me, and appreciate and encourage anyone else who wants to keep me company along the way.
Good luck, and hope this helps!
