Hi everyone!
Starting to get really frustrated

My weight is not going down (but not gaining either), even though I'm walking everyday (brisk walking according to Fitday) for an hour and eat about 1400 cals a day. Usually fat is 65-70%, 3-5% carbs and then the rest is protein. I don't understand what I'm doing wrong here. I really wish to get the weight off, but I'm still stuck at 165 lbs.
Could it be that I'm not eating enough veggies?
I know that I may be a bit low, eating about 1 cup of chopped cucumbers and ½-1 cup of green cabbage. I do get some carbs from regular mayo and eggs as well, but that should just be minimal.
