I confirm, getting rid of sugar helps with weight-loss. However seriously "getting rid" of sugar is something much more extreme than what @alexandraioana26 describes here.
No stevia for instance. Stevia does have calories, not as much as sugar but it does have some. And no fruits. Fruits contain fructose which is without contest the worst sugar - the fastest to be assimilated. Dates for instance, when dried, are worse than pure sugar bombs.
"No sugar" for me means at most yoghourt "nature" or cheese - even that contains lactose, which is a sugar. And oatbran - it does have some residual glucose but not that much.
