This is Keto Fitness Club's Megga Bread recipe. You can also buy it ready made from KFC's baker. It has a few special ingredients - vital wheat gluten ( I found the best value was an offer for a kg on amazon) and xantham gum (major supermarkets - probably not the value ones). It also uses yeast for the rise and has alternatives for other ingredients which you can get from Lidl etc so you will probably have some in the house . You can make it in a breadmaker or by hand. Recipe and youtube tutorial here.

Updated 6/6/21: I made the megga bread recipe with chia seeds and a Lidl flax seed mix. I had several slices whle still warm with butter and marmite. The crumb was very fluffy/light and the crust was wonderfully crusty. I used lard rather than butter.
l'll be interested to see what it is like cold. I think I may use some almond flour next time if the crumb still seems light when cold.
lt was a very wet claggy dough. I used my Lidl electric hand held mixer to knead it. Although the recipe says you can knead/mix by hand, I think that would be so sticky, you'd have a lot of dough stuck to your hands. I used wet hands to shape the top of the bread. That created a sort of crust when it was proving in the oven at 50c. Maybe, it would have been better if I'd slashed the top before it proofed. Nothing about slashing the top in the recipe. I smoothed it and it was quite shiny on the top. Maybe a claggy unsmoothed top would be less shiny.
I'd probably double the recipe next time to make a taller loaf, and then put some sliced in the freezer. The batch made according the recipe just about came to the top of the loaf tin in the middle, so each slice is less than half the height of a regular loaf. It rose well - so I thInk double the recIpe will be good. l will also get smaller loaf or cake pans so I can make a small cake or a one batch of bread. I lined the pan with greaseproof paper - and the loaf came out easily.
