Considering your age such situation with weight is sadly a typical thing because during aging your metabolism changes too and becomes slower so many people gain weight after their 40-50s. Because of that it can harder to lose weight too but it's possible, I know many such examples and people who are in a really good shape despite of their age!
Your programm for weight loss seems ok but I can recommend to use such tips in addition:
- don't skip your breakfast because avoiding it usually leads to eating more throughout the day
- never eat at night and before sleeping, it's bad for your stomach and weight too, also avoid mindless snacking while watching television and so on
- vegetables and fruits should be a base of your daily menu, not meat and other products with high calories www.healthline.com/nutrition/lose-10-pounds-in-a-month
- add protein for every of your snacks and meals, such products as lean meats, eggs, peanut butter, low-fat yogurt, nuts, beans etc. are perfect for this
Also I think that you need to add more exercises in your regular schedule. You don't need to go to the gym, choose the one activity you like the most of all like yoga for example or a basic fitness complex and make it reguraly. Swimming, walking and running are very helpful in this case too.
I should mention that sometimes problems with weight loss are connected with hormonal imbalance which can be an aftermarth of the aging too. It usually can be fixed in many natural ways but in some cases only professional medical treatment is helpful www.nexelmedical.com/ .
