I&#x27;ve noticed in some cases that exercise can actually stave off hunger pangs - both while doing it and afterward for a while (you want water more than food) - and in this manner it can act as an appetite suppressant.<p>As long as you ignore the body&#x27;s impulse to eat more than usual when you finally do sit down for a meal, it can very much work in your favor.  There&#x27;s also a phenomenon people refer to as &quot;shrinking stomach&quot; (that I&#x27;ve observed first hand) where your body adapts to feeling more full on less food.  I don&#x27;t know if your stomach actually shrinks, but it feels like it.<p>If you don&#x27;t sufficiently often resist the urge to eat more than you need, your body will adapt to that intake level and there will most likely be a rough patch when you try to change the trend.  I believe most people can push past this uncomfortable period and stop feeling deprived after a while.
