Will drinking protein powder make me gain weight?

I lost 70 pounds already and I’m vegetarian so I need protein I was wondering if I drink protein powder as a meal replacement (140 calories per scoop) I don’t work out besides 200 crunches a day and a run (15 mins) will I gain weight from the powder I won’t eat anything additional

I’m 133 pounds if that matters

Powder

140 cals

9g carbs

20 G protein

I’m drinking it cause I don’t get enough protein in my diet
