Sorry to hear about the Covid issues.
I'm not familiar with the tracker you're using. Are you actually weighing your food? What kinds of things are you eating? What kinds of exercise, rough expenditure? and what deficit are you aiming for?
Yes, I weigh everything & log it in the tracker app.
I'm basically on an omnivore diet, although it is much more plant based these days, organic as far as possible:
Just the very occasional portion of red meat, but more poultry & fish. Veggie burgers/sausages instead. Tofu.
Eggs & dairy every day, full fat milk & yoghurt.
Loads of fruit & vegetables, although I try to minimise the higher carb varieties. Lots of pulses/beans/lentils. Not that I'm counting, but I probably attain the recommended 30 different varieties each week.
Some wholegrain bread, but zero pasta or rice.
Olive oil or avocado oil, definitely no seed oils.
Definitely no junk food of any kind.
I believe in diversity for microbiome health & am reluctant to exclude any particular food groups without very good reason, although I had to do so for a while whilst I was suffering from IBS & on a low-FODMAP diet. Fortunately that has now resolved.
Activity/exercise: Light. Usual activity around the house. Walks around the local area, adding up to around 6000 - 7000 steps/day. Gentle resistance training & muscle building exercise, all limited by overall health issues & low energy levels.
I have no idea how much energy I'm expending, but the tracker app calculates that a 500 calorie deficit equates to a current intake of around 1550 calories to achieve a weight loss of 0.5 kg/week. I'm aware that the whole weight/calorie connection is somewhat controversial.
