The whole idea around intermittent fasting revolves around eating in a specific time window, outside of that you don&amp;#x27;t consume any calories at all.
Many people I know of do this, in order to lose some weight or gain muscles without adding too much fat, never heard of this problem.</text><parent_chain><item><author>saiya-jin</author><text>Had a friend in university, he did military service for 1 year and the only thing he had for breakfast during that time was a strong black coffee without any sugar nor milk.&lt;p&gt;He screwed up his digestive tract for good - there is apparently something in coffee that is quite aggressive on stomach and gets neutralized when mixed with any sugar&amp;#x2F;milk&amp;#x2F;food.
