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><author>ghshephard</author><text>What I was trying to say, perhaps poorly, that is if you were heavy because you were working out a lot, and eating a lot, and then decided to lose weight by reducing the eating&amp;#x2F;working out, you can end up being skinny&amp;#x2F;fat&amp;#x2F;weak.&lt;p&gt;At the very least, doing regular body-weight resistance training (pushups, situps, pullups, air-squats), helps to reduce the amount of muscle you are losing while you are losing weight.</text></comment>

Instead of heart disease and joint damage, you end up with osteoporosis, anemia, etc.&lt;p&gt;Losing weight without paying attention to nutrient intake and balance can have similar effects, even if you&amp;#x27;d be at or above healthy weight losing 50lbs.</text></comment>
