Cutting snacking, calorie dense foods, and counting caloiries.

Calories in/calories out is the only thing that works long term. You dont go on a diet, you change how you eat permanently.

I keep bread in the freezer so i dont snack on it. I only have a small desert. Measure portions until you have a good eye for it, etc.

Working out to burn calories is unsustainable for the majority of people.

Stop drinking soda and alcohol at random. They are loaded with empty calories. You can easily drink 600-1000 calories a day with soda if you have a couple of glasses with meals and snacks.

I found out I was diabetic and had damage to my eyes. So I switched to a diabetic diet overnight and lost 12kg in a couple months. Kept it off too, gained a little back over Christmas (because Christmas is all about the food for me) but lost it by end of January again.

No sugar unless it's fruit, very controlled carbs portions and all wholemeal/ brown varieties. Some days no carbs only vegetables. I've not eaten potatoes since October. Snacks are nuts or fruit, deserts are yogurt and fruit with some dark chocolate every now and then to help with the sugar cravings. It's not easy but I really want to keep my feet and eyes.
