There are probably some people who can’t give up bread but the majority just doesn’t even try. They doesn’t even try to IMAGINE that, it seems… My SO ate bread with everything. Then he stopped for years easily when we tried to figure out if eating gluten free makes a difference for us. It didn’t. Giving up gluten wasn’t even hard for us. You don’t know till you try, usually… Your friend probably just doesn’t want to get out of his comfort zone but it doesn’t mean it would be super hard if he tried. I never had so much surplus fat but if suddenly had, I surely would think differently. I would give up ANY food for my health I imagine. But I don’t need to do that, thankfully.
I’m sure the friend should try to restrict himself. We shouldn’t just eat whatever we wish, SOME restriction must be applied if we don’t desire the right things in the right amount. It’s pretty basic to me but a foreign idea for many, sadly.
It’s especially sad if people never even try a new, better lifestyle that would feel way better. I love carbs in general (especially veggies, this made keto a bit difficult in the beginning) but I’m lucky I tried low-carb and later keto. I will never go back to high-carb, I’m a hedonist so I want to feel better and nicely satiated all day. While eating great food. I had no idea how keto will feel and how it changes me. I had to try. And we can change a lot. Bread really doesn’t seem important, it’s just commonly used. We can break that habit. Many of us can “substitute” it with vegetables or nothing in most cases. I personally need my keto bread sometimes (when I fancy for Marmite, for example) but it’s not an every day occurrence.
Lowering the carb intake is very often a good idea. Even if it’s not actually keto. Many people feels better and loses fat on low-carb, 80g worked nicely for me, for example. So even if giving up bread sounds so hard, some efforts should be made (including less bread or at least lower-carb bread… bread is just too carby and people eat too much of it).
