I've done this without ever being hungry., although rapid weight loss in itself isn't ideal for long term sustainability.
Cook everything from scratch. Absolutely no ultra processed foods ( generally those containing additives and artificial preservatives - usually a long list on the label. Canned things fine as long as no sugar or other preservatives). No low fat foods. Sugar is the enemy, not fat.
So cut out sugar ( including honey and sweet fruits, especially tropical ones as they are very sugary) No wheat based products. Nothing containing veg oil, use extra virgin olive oil or lard ( yes really) for cooking. Greatly reduce your carbs. No alcohol.
Lots of veg, dairy and protein. Eat butter and cheese and full fat Greek yoghurt.
Keep an eye on portion sizes. Drink water. Increase your exercise but don't go totally overboard as it may over stimulate your appetite.
I can't face 5:2 as I hate being hungry. So I do 16:8 with the occasional day of 18:6 combined with all the above.
The weight falls off, and I am menopausal as well. When I stop eating this way the weight piles back on again.
I've been eating this way for over two years and lost four stones and feel and look great. It's a really enjoyable and healthy way to eat. Come and join us on the 'why we eat too much' thread in weight loss chat if you like.
