&gt; but [a vegan diet] is the best way to prevent&#x2F;cure T2 diabetes without causing other issues.<p>There is basically no science that allows you to state this confidently.<p>&gt; The fact is: fat tastes good. Nobody want&#x27;s to give up bacon and cheese so we keep looking for ways to say it is &quot;OK&quot;. Big Pharma really wants you to keep eating your fats too. They make billions of dollars a year selling people drugs to offset their lack of will power.<p>It&#x27;s been repeatedly shown that basically all fats, even the once thought of as &quot;bad&quot; like saturated fats, do not clog arteries (or raise cholesterol, while we are here) when not in the presence of caloric surplus.  I don&#x27;t follow it, but the success many have had with the keto diet is one great example of this.  It&#x27;s just not as simple as you are saying.
