Physical inactivity is the easier half of the question to answer. Lean muscle mass generally reduces risk of injury, increases bone density, increases bmr, decreases body fat, improves blood glucose levels, and helps with balance. Intense exercise can actually decrease appetite. Exposure to bright light throughout the day (during exercise for example) has also been shown to decrease appetite and increase satiety. Visceral fat can be more common in sedentary life styles and is suspected to cause pro inflammatory compounds and is correlated with many negative health outcomes.
Here is a study that I found after a quick Google that seems to give a better explanation than I have done above.
A piece from the abstract:
>Physical fitness appears to buffer against stress-related disease owing to its blunting/optimizing effects on hormonal stress responsive systems, such as the hypothalamic–pituitary–adrenal axis and the sympathetic nervous system. This blunting appears to contribute to reduced emotional, physiological and metabolic reactivity as well as increased positive mood and well-being. Another mechanism whereby regular exercise and/or physical fitness may confer resilience is through minimizing excessive inflammation. Chronic psychological stress, physical inactivity and abdominal adiposity have been associated with persistent, systemic, low-grade inflammation and exert adverse effects on mental and physical health. The anti-inflammatory effects of regular exercise/activity can promote behavioural and metabolic resilience, and protect against various chronic diseases associated with systemic inflammation. Moreover, exercise may benefit the brain by enhancing growth factor expression and neural plasticity, thereby contributing to improved mood and cognition. In summary, the mechanisms whereby physical fitness promotes increased resilience and well-being and positive psychological and physical health are diverse and complex.

Reply to comment by GimmeAMalt in LPT: To get the most muscle/sculpting for your buck at the gym, focus on compound lifts—the exercises that recruit multiple muscle groups. You only really need overhead press, bench press, squat, deadlift, rows, dips, and maybe pull-ups. These will give you most workout for the energy you put forth. by [deleted]
A lot of isolation exercises aren't really necessary if you are doing compound lifts through a large range of motion.

It can reduce appetite, not will reduce appetite.

Take this with a grain of salt though, there are studies showing that sun exposure can trigger food seeking behavior. I believe msh is more effective and working in concert with leptin when increasing satiety.
