Bloating

Im curious, I have been bloating alot in places i normally dont. I know theres many different reasons for it but im wondering what to fix to get rid of it i miss my semi flat tummy XD No im not due TOM bloat for 2 more weeks (iv been at this nearly a year its like clockwork starts 2 weeks after my last period)

I have been walking alot atleast 5 miles a day over what i used to(10-15 miles a day), And almost daily. No real rest days. But i dont think thatd cause bloating in my ribs and belly so much as my legs (maybe)

Im not dehydrated.

I have been upping protein for a few weeks but im still relativly low protein i just hit my goal of around 70-80g. bit hard on a low calorie diet to get huge numbers.

Iv actually been lowering carbs and i know my body LOVES carb iv lost 95 pounds eating alot of them. Could the bloating be related to this? i know itd be backwards to most people but since my body runs best on carbs could lowering them and upping protein do that?

Iv also been eating at a very large defecit this week so im not eating to much, Could eating to little do this? and in such a short time? I average - 1200-1800 (140 pounds at 5 ft 3 so i know this defecit is way to agressive for me long term) since monday (no lectures please iv been eating around 1500 cals a day just walk ALOT and i plan to refeed on easter sunday, Im not left hungry my calories have been very nutrient packed)

honestly i was slimming up and not bloating now i just feel pregnant even though iv been eating alot less im not so much worried as curious to figure itt out for the future
