See the scientific wording

Women who increased their daily consumption of sugar-sweetened soft drinks from less than one drink per week to one or more drinks per day gained an average of 4.79 kg over four years, significantly more than those who maintained low intake or reduced consumption, suggesting that increased intake of these beverages contributes to substantial weight gain in young and middle-aged women.

Why this might work

Drinking sugary sodas adds extra calories that the body does not compensate for by eating less food. These extra calories are stored as fat, causing the body to gain weight.
