Which diet?

[TigerTooth]

17st 2lbs - 5'4. size 20.
Shins filling out straight leg jeans.
Depressed - hate myself for being so weak.
love love love sugar and carbs - not into big portions at all but love the wrong stuff esp biscuits.
Any advice on which diet to try?

I don't think a 'diet' mindset works in the long run, try changing your habits.

Try combining a little bit of the wrong stuff with a lot of the good stuff at meals.

Keep a diary of meals and snacks, you can use the MyFitnessPal app to help you.

Start walking in the evenings (assuming you don't already work out) and go from there.

I've started using the myfitnesspal app - it looks great.

I follow slimming world which has given me great results over the years. But! Just because I'm allowed unlimited free foods (potatoes , rice , pasta included ) I don't take advantage of that. I make sure my potion sizes are right. I find it's best for cooking for the family too.
