Honestly, weight loss is a process, and maintaining weight loss is bloody hard work!
Once you become overweight, the fat cells in your body lay dormant, and are ready and waiting to get filled up again. It takes immense will power and lifestyle change to fight against your body in the long term.
The first thing I’d suggest is having real awareness of your current eating, and current calorie needs. Ignore anything that says ‘the average woman needs x calories.’
Work out what your current calorie expenditure is, based on your height and weight, and your lifestyle. The vast majority of us are sedentary, myself included! A dog walk and an average of 10k steps a day still makes me sedentary, just less so than the majority. I haven’t done a work out for years, not real exercise on a consistent basis, so I can’t claim to be moderately active.
Once you know that, it’s then a question of really knowing how many calories you consume daily, and creating a deficit.
I would encourage the WLI because it will maintain your motivation, reduce food noise, and actively investing in yourself and health will make it a lot harder to fall off the wagon.
