Did it for the first time since the 2000s.
Back in the day, the mistake I made was that the fats were too low so I shrivelled up.
This time I was fat heavy. Felt good but the explosive diarrhoea after every meal got too much, and I can't risk that happening when I'm not at home. Had a bag of M&Ms today to give my gut the carbs it needs lol. Only lasted around 2 weeks.
Moving forward I'll still be eating keto type meals but in lower quantities + 100 grams a day of carbs from oats or rice.
I think everyone's bodies are different. Some people evolved to run on carbs better whereas others are meant to be primarily run on fats.
