Dear Former Weight Loss Clients (you know who you are):
I'm sorry.
I'm sorry because I put you on a 1,200 calorie diet and told you that was healthy. I'm sorry because when you were running 5x a week, I encouraged you to switch from a 1,200 calorie diet to a 1,500 calorie diet, instead of telling you that you should be eating a hell of a lot more than that. I'm sorry because you were breastfeeding and there's no way eating those 1,700 calories a day could have been enough for both you and your baby.
Undernourishment or Chronic Hunger
"The average minimum energy requirement per person is about 1800 kcal per day." http://www.fao.org/hunger/en/
How much food do you need?
"On average, the body needs more than 2,100 kilocalories per day per person to allow a normal, healthy life." http://www.wfp.org/hunger/what-is
According to the World Health Organization, a diet under 2100 calories for average men and under 1800 calories for average women is classified as a “Starvation diet.” http://hbmag.com/the-calorie-myth/
