All of the fad diets that actually worked over the past two or three decades have one thing in common: DON’T EAT SUGAR.
The “Eat to Win” diet of the ’80s was a high carbohydrate, low protein, moderate fat diet that worked. The guy who invented it was Martina Natrilova’s trainer, and it worked for her.
The Atkins diet is just the opposite, low carbohydrate, moderate fat and high protein, and it works too.
Both these diets work as long as the dieter actually follows them.
The one thing they have in common is DON’T EAT SUGAR. Don’t drink sugary caffeinated beverages. Don’t eat ice cream. Don’t eat candy bars. Don’t eat donuts.
The really bad thing is that eating sugar makes you hungry.
It’s not rocket science, but it’s harder than Hell to give up sweets if you have a sweet tooth.
