Sorry to hear your struggling with this.
I’m a big fan of cutting bread to reduce weight. Switch your sandwich for a soup. Switch your cereal for a smoothie some days.
Cut chips and crisps.
Switch up spag Bol for chicken, rice, veg some days.
Avoid empty calories like dressings on salads, mayonnaise etc. And avoid alcohol, chocolate and sweets. That doesn’t mean cut EVERYTHING out, just rein it in when you can.
Up your walking. Use your lunch hour to go for a walk when you can.
Know that your body has a happy weight and just focus on stimulating your metabolism and getting lots of fruit and veg.
Portion control is important too, so the idea is not to overload your plate.
I don’t agree with fasting, but I hear lots of people are fans. Do some research if you think that would help.
Ideally, try to refrain from any diet that makes you hungry. If you starve your body, it will only make weight loss harder and it’s unsustainable.
The goal is to eat healthy foods and enjoy it, add in lots of walking and you’re focus on building your energy levels.
Also, the amount you weigh is irrelevant IMO. If you’ve made positive changes to your diet, you should notice it first in the way you feel and how your clothes fit. Don’t focus on the scales.
If you have lots to lose, it will slowly go down, but a good diet should take time given it’s a lifestyle change you slowly integrate into your day.
I hope that helps!
