I have a bit of a problem. When I was vegetarian I was pretty sedentary & when I decided to go vegan three weeks ago I also started running again (I ran before regularly, but it was about two years ago). I was keeping a food diary to make sure I got enough proteins & I take a multi-vitamin, but I've never been big on calorie counting. After reading that some of my favourite foods had <100 kcals I was concerned and kept a counter. I found I was eating between 600 and 800 kcals a day. Obviously this is bad especially when exercising & I have lost weight but only about 2.5lbs a week which I thought was healthy. I'm still about 126lbs at 5' 7" so I'm not "skinny" but at this rate I will be. I'm also worried about my body burning muscle in "starvation mode". However, this is purely a number problem. When I was eating that number of calories I never felt lethargic, tired, or dry skinned. I had no dizziness or any other symptoms of undereating & I only drink as much water as I need and the odd cup of green tea.
So I bought avacado, whole nuts, hummus, ate more peanutbutter than usual, & even made cashew cheese. My problem is that I am not a big eater & when I'm full, I'm full. I was eating to fullness before but now even after introducing these foods I find it difficult to eat more than 1000kcals because I feel full & sick as they are much heavier than I'm used to eating in Summer. Also eating so much is making me lethargic.
tl;dr: I eat way too few calories (<800) & I exercise regularly. I have upped to calorie rich foods & bigger portions but feel sick eating so much food all the time and find it hard to force myself knowing I'll feel sick, even though at a push I'm getting about 1000kcals a day. Is there anything I can do that doesn't include eating more food?
