That said, there are other potential benefits and issues. People tend to forget how energy dense sucrose is. Only fats are denser. (incl. nuts which are mainly fat and protein) So whatever you are replacing them with, you will eat much of, unless it is fat or oils. Or you will lose weight.
But the article is not about just removing the sugar. As the author discovered, just by giving up on sugar one changes the whole diet. He could no longer consume any junk food and had to start cooking himself. So the real benefits could be in that switch, not in avoiding sugar per se.
Right. Which makes the 12 lbs lost over 2 weeks very suspect.
> The question is will replacing a couple hundred calories of sugar with something healthy, like nuts for example, cause one to lose weight?
Yes, but with all diets, it will be temporary.
Losing 12 pounds in 2 weeks is not "healthy" weight loss, especially for someone who is already at a "healthy weight."
Weightloss over a long period of time is "calories in" = "calories out", but that becomes a matter of will and control, over what your body is going to do (which is not want to lose much weight).
