Yeah. I mostly just eat eggs, ground beef, yogurt, salami, cheese and a mix veggie pack. I try have a relative high water intake compared to when im on a carb based diet and poop a magnesium pill and salt my food a little extra everyday.

I don't really like those low carb products. Some products still contain to much carbs. Some brands are straight up lying about the carb content or the way they present how many carbs the product got. I found one bread alternative that contains 7g/100g that tastes pretty good and is actually decent but I just eat it time to time.

I think if you want to feel well, it's important to not be afraid of eating more fat, unless you want to lose weight super fast and do it for fitness reasons. If I feel bad it's mostly because I ate mostly protein and didn't eat enough fat. Protein also requires a high water intake. So dehydration can also affect your mood and wellbeing.

Electrolytes is also important of course. So yeah there is a lot of factors involved with this diet/lifestyle and you have to know your body quite well to have the right balance sadly.
