I agree with this approach, I was a size 24, weighed 14 stone 7 at 5ft 4 on 1st July 2022, I was diagnosed with diabetes and didn't want to take medication so was allowed to change my diet and exercise.
I gave up potato, bread, pasta, rice and sugary foods, I allowed myself up to 130grams of carbs a day and tracked my intake on an app.
I allowed myself Porridge as even though a carb I also had high cholesterol and wanted to see if I could reduce without statins.
A typical day for me now is
Porridge with frozen cherries and sometimes a couple of squares of dark chocolate melted into it (tastes like black forest gateau) I added the carbs consumed into my tracker)
Lunch would be something like a cheese omelette with a salad or ratatouille, sometimes I would have cauliflower cheese. or a roast dinner with only 1 small roast potato, but tons of veg.
Tea would be soup (I love the ones from the nourish range, very filling and only 168 calories for 500g,
If hungry I would snack on walnuts, cashews, Greek yoghurt (full fat as less sugar and more filling), chicken etc
I would allow myself red wine or the occasional gin and slimline tonic.
I am now 8 stone 10, and a size 10 and my diabetes is in remission, sadly I still have high cholesterol, which turns out to be genetic and not connected to my diet to I will need to take statins.
I lost the majority of the weight in the first 4 months, then it slowed to 1 pound a fortnight, I feel healthier and it feels sustainable. A lot of my issue was I just used to eat for any reason, out of boredom, sadness, etc, it was my hobby, I just ate until I felt I had filled an emotional gap inside me.
I do eat a few carbs now, but not like before, I may have seeded sourdough with some peanut butter or some brown rice with a meal, and allow myself 2 roast potatoes and a Yorkshire pudding with my Sunday roast, I just make sure I am having a lot of green veg and protein.
I am 58 and spent years yo yo dieting, it wasn't until I had this health scare I looked into the actual nutrition of what I was eating and was scared by the possibility of going blind or losing a limb (couple of complications from diabetes) Good luck x
