As we age, it does get harder to lose weight especially if you've gone through or are approaching menopause. So, don't beat on yourself because the weight isn't coming off fast enough. If you continue to do your best to eat right and get some regular exercise, the weight will come off. But, you must be patient with yourself and your body.
When is the last time you had a physical or talked to your doctor ? If you haven't had time for yourself because you've been taking care of everyone else, then you need to set aside some time for yourself. Talk to your doctor. find out what your blood pressure, blood sugar, cholesterol, etc... all are. As you change your habits to become healthier, those numbers will change for the better.
Also, if you do find yourself turning to alcohol to help you feel better, that's not going to help your situation get any better. If you can, you've got to try to reduce the amount of alcohol you're drinking. It's not helping your well being or your waistline. When we start drinking too much, we don't think about how much we eat. And if you've seen your weight go up, it's probably because you're eating more than you think.
If you haven't seen your doctor in a while, I'd start there. As far as losing weight, start with simple changes. Walking is wonderful cardiovascular exercise. There are members who will tell you how they lost 100+ pounds just by walking and watching what they ate. So, keep walking. it will make a difference with time.
