I am trying to convince someone that your metabolism slowing down cannot offset your caloric intake enough to cause to maintain weight in a deficit. I would like some research to cite in support of this.

The Compendium says,

Your metabolic rate can slow down during weight loss, but it will never slow to the point where it causes you to maintain or gain fat; in this sense, "starvation mode" is a myth.

People concerned with starvation mode are concerned that by lowering their calorie intake drastically their body will retain fat to compensate. This idea was popularised due to the Minnesota Starvation Experiment in which subjects were given 50% of their daily calorie intake for months. The result being that they lost fat until they had nearly zero fat left to lose and their bodies simply could not get the calories anywhere else. Concisely put: starvation mode happens when your fat is nearly entirely gone and your lean tissues are, quite literally, wasting away.

When you have a simple caloric deficit, your body will almost entirely make up for it with fat stores. There is a small metabolic adaptation that happens due to the lowering weight of your body and changes in leptin, thyroid, insulin and nervous system output. That metabolic rate tends to reduce more with more excessive caloric deficits (and this is true whether the effect is from eating less or exercising more) and people vary in how hard or fast their metabolism slows down. Women's bodies tend to slow slightly more. However, never is the slowing of the metabolic rate sufficient to completely offset the caloric deficit that initiates it. Further and further deepening of the calorie deficit simply yields only smaller incremental returns, but never stops or even slows fat loss.

What are some peer-reviewed papers that support the statements made here? I've always argued this point to others purely on the basis of physics - mass is equivalent to energy, so if you burn more energy than you take in, you will have to lose mass. But I am trying to talk to someone who is likely to demand research that shows this, so if anyone could point me towards that, I would appreciate it.
