If you want to lose weight you should start by avoiding sugar and starch (like bread). This is an old idea: For 150 years or more there have been an infinite number of weight-loss diets based on eating less carbs. That’s dieting for masochists. Sooner or later a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
The main advantage of low carb diets is that they cause you to want to eat less. Even without counting calories most overweight people eat far fewer calories on low carb. Sugar and starch may increase your hunger, avoiding it may decrease your appetite to an adequate level.
