Without a doubt - garden, cleaner, de-clutterer. You'll be buying help, and more time for yourself.
& change your eating habits- if you have a big appetite you can still eat, as long as it's different food. Diets don't work for me & I don't have the time and inclination for calorie counting. I'm never going to have a small appetite.
Instead of rice, I eat cauliflower rice. No bread - crispbread instead, any that's not too crunchy. Minimal processed food. I still have potatoes as saw a poster on here once talking about resistant starch - lots of information about it online but basically once cooked, cooling potatoes then sticking them in the fridge overnight turns their active starch into resistant starch.
Resistant starch is a pre-biotic and also has around 40% lower glycaemic impact. so it's beneficial for gut health and weight loss. It's worked for me. Not just for weight, I have more energy. That surprised me.
Don't be too busy for your health, it's just not worth it. If your health goes then your job goes.
Get the cleaner, gardener etc and work out at home, even 20 minutes daily in 2 x 10 minutes bursts is something. You can lift dumbbells and do leg raises whilst watching TV.
Ideally you'd get a job which doesn't require a 3 hour commute but if that's not possible at least you can free up time for self-care and relaxation.
I've been thinking about getting a cleaner and this post and thread has decided me. Cleaner it is.
