Oh yet another person quoting the Minnesota starvation experiment, what a surprise. I mean it happened 80 years ago and there were a couple dozen and all the participants were young white men, but I’m sure it’s universally applicable, right?

1200 cal may be too few calories for many people. It’s too few for me. But some people are a lot smaller than I am some people have faster metabolisms and some people have slower. Unfortunately the only way to know what works regarding weight loss for most people is trial and error.
