Different people react to fasting differently - some continue to burn calories and drop weight, some just go into starvation mode, have their BMR crash through the floor, and end up exhausted all the time because their body is fighting like crazy to conserve energy.&lt;p&gt;Likewise - some people, when they start to eat carbs, see their BMR ramp up, are full of energy, and end up running 5-10 miles a day to burn that energy off, and are pumped the rest of the day.&lt;p&gt;Also, focussing on weight to the exclusion of everything else is really horrible.  It&amp;#x27;s pretty easy to lose 40-50 pounds and end up being much less healthier than you were before if you aren&amp;#x27;t careful.    Having some sense of your V02 max, your strength, endurance, flexibility, etc.. are sometimes as important, if not more important, than what your weight is to +&amp;#x2F;- 20 pounds.&lt;p&gt;Everybody is somewhat different in how they&amp;#x27;ll react to various diet and exercise regimes.  Understanding that, and taking a bit of time to watch how your body responds, is the important insight here.</text></item></parent_chain></comment><story><title>Machine Learning and Ketosis</title><url>https://github.com/arielf/weight-loss</url></story>
