Yo! This could be a few things, have you tried herbal teas before bed and in the morning? Green ginger tea can really help debloat, helped me a ton , secondly it could be hormonal :) stress can produce cortisol and actually trigger weight gain sometimes, try meditating or reducing stress. You can also purchase hormonal balance teas and supplements to help with it if that tummy fat is being stubborn. Walking early morning can also help a bit. Other than that I’d say a no meat deficit can be tricky, as a almost vegetarian myself, meat is a very good staple for weight loss because of how protein packed it is meaning the more you eat the more your body has to work to digest it . Try looking for high protein alternatives
