I am perimenopausal, 5' 7" and 77kg, aiming for nearer to 68kg. I have a calorie limit of 1400 per day and like @HappyAsASandboy I don't find it tricky at all. I'm never hungry. I've lost over 5kg in just under 2 months, haven't cut anything out completely, but do focus on protein, good fats and lots of veg/salad. No, or very minimal, alcohol. Lots of energy and sleeping well. Lift weights, yoga and walking (but not every day, if I'm honest!)
I eat eggs every day (always keep hardboiled eggs in the fridge for a snack too), tuna, chicken, fresh anchovies, cottage cheese, kimchi or sauerkraut, lots of salad, cucumber, tomatoes, etc. I tend not to eat breakfast (which does help to keep the cals down tbh), then I have a light lunch of around 400 cals (protein and salad mainly), lots of water, then a 'proper dinner' often followed by Greek yoghurt, cinnamon, linseed and berries. Tonight's dinner is chicken, spinach and lentil curry. I still eat bread, chocolate, pizza, potatoes etc but just not every day and in much smaller amounts.
It works for me. It has been a bit of a shock to find out just how few calories I actually need. I was definitely eating (and drinking) far, far too much and a lot of it was crap. I feel so much better now.
