This is a valid point. On a doctor monitored weight program I found out: At my height (5 feet nothing) and metabolism I have to work out 2 hours per day 7 days a week and consume 1200 or less to maintain being 40 pounds over weight. If I want to reach chart ideas I have to eat less than 1000 calories a day. Yes, I can go on an extream diet and lose weight but keeping the caloric intake on less than what most people would find hard to do, on a daily basis is hard. Which is why my weight goes up and down. Don't judge anyone on their weight unless that person is yourself, since you don't know their story.Probably the only thing that's hard is coming to terms with the reality of it all- exactly how few calories it takes to really run a body is eye-opening, along with how much exercise it takes to really burn it.
As for OP, as she pointed out, her problem was not the weight but rather the sense of entitlement the person beside her had with regards to personal space and attitude. It would have been the same issue if it was a tall skinny person who kept jabbing her in the ribs with total disregard. Definately a valid point. Very glad to see that the seats on first class gave her a much deserved break!
