Weight loss accountability/support 2024 edition

It doesn't have to be super difficult. I'm aiming for similar, which is about 10% of my bodyweight. Aiming for a patient and sustainable approach of about 0.5kg a week, which means a deficit of 500kcal-ish a day. If you've got more capacity for misery I think you can safely go up to 1kg per week but obv that means a hefty deficit BUT sometimes that's easier to take when you know it's going to only last 7 weeks.
"it depends" I guess

It can be very easy, and take a long time, or it can be really horrible and take a few weeks.

The former is likely way more sustainable, as you are going to be eating pretty much the same amount of food post-diet, as you are during.

I'm aiming for 0.25 - 0.5kg a week to drop 10kg, by just eating more sensibly (no crisps, chocolate, biscuit binges), basic CICO, but without calorie counting.

Last year I dropped 10kg at 1 - 1.5kg a week, and it fell apart afterwards. The difficulty for me was not the hunger, but the mental effort needed to plan and manage a calorie restrictive diet, with very pedantic calorie counting, in such a way that I was eating "normal" food, and varying my diet a lot.

Horses for courses, though - what works for others may not suit you.
