Hi guys and gals, I'm Kier I'm 27, and I'm restarting the gym after some 1.5 years out due to health related issues (no details).
I'm currently sat around 150/152kg(23.9 stone) and im 183cm (5.11ft).

I'm looking for mostly diet advice as I have no issue with eating less calories my issues arrise when it comes to my stomach movement, i either have rabbit droppings or complete liquid no matter the fiber intake so I'm curious is anyone has issues like this and has managed to solve them, I get most of my fiber from oats/bread/baked beans, since I'm not a fan of vegtables other than the tasty unhealthy ones.

while you're here I'm also wondering if i should go straight into my old routine of 5 days a week in gym and 2 days rest or what I want to lose around 20kg before summer/july, and would love some advice from someone or ones that have been through similar transformations.

anyway thank you for taking the time to read and i wish you the best of health.

If an admin could add "Gut health" to title that would be awesome.
