I am on day 11 of counting my calories. MFP suggested I eat 1,200 calories for my 5’4 height. I started at 146 and I’m down to 141 after the 11 days. So far most days I’ve been okay on 1,200 calories. But tonight I was laying in bed and my heart was racing. When limiting my calories in the past, I’ve noticed this happens. Is this a sign I’m not eating enough? Has anyone else noticed this is a sign of too low calories? I know people who fast all day at times so it’s hard for me to believe it’s from that. My stomach is not growling or anything. My goal weight is 120.
