Can I Lose Weight by Drinking Lots of Coffee?

Lose 33 lbs. by Drinking Coffee?   A while back in Minnesota, I was giving a speech and I took a detour during the speech to talk about some of the seemingly strange changes in diets that have led to people losing large amounts of weight. 

Afterward a woman in her early fifties excitedly told she had last 33 pounds in the past 6 months by making only one change: She started drinking black coffee. More accurately, she had started drinking black coffee because she had stopped drinking it with cream and sugar.

Of the hundreds of small changes people have told me about that have helped them lose 25 lbs or more in less than a year, this was a first. When I was back at the hotel, I did a little math. Unless this woman drank over 7 cups of coffee a day (a possibility), the math didn’t add up.

What I suspect happened was that she did make this cream and sugar change. But this cream and sugar change probably also led to her making other changes that were less obvious to her. It might have given her less of a sweet-tooth or less of a reason to sit down for a snack.
