Peri and full menopause means (unfortunately), you can't expect to do the same as you did before and get the same results.
Weight loss comes predominantly from what you put in your body, not exercise.
Keep the exercise up as it's good for your fitness and overall help.
But if you want to lose weight, you'll have to adjust to a new way of eating. Not diet, but a permanent change.
The alcohol needs to reduce because you won't process it as easy as before.
Your calorie intake during peri and full menopause will need to be reduced further if you want to prevent the weight gain. It's shit, but it's just a fact of life.
You need to weight up (no pun intended) if the misery you may get from reducing your calories further outweighs the desire to lose the weight.
Also, don't be sucked in to the "I cook from scratch" myth in that you think that means you should be thin.
Calories are calories. 500 calories of homemade stew and 500 calories of McDonalds is still 500 calories. Yes, the homemade stew is better for you healthwise. But for purely weigh, they are the same.
Carry on with homemade food, but you need to drop your portion sizes.
