Eating noodles every day in and of itself is not going to make you lose weight.
Eating in a caloric deficit every day will make you lose weight, regardless of whether the calories are coming from noodles, chicken breasts, pizza or Mc Donalds.
Take your weight, multiply it by 15 and that is the amount of calories you need to take in each day to maintain your current weight.
Eat less than this each day to lose weight.
Many packets of ramen instant noodles are about 400-500 calories.
So if you were say....150 pounds. Your maintenance calories would be 2,250. You would be able to eat 3 packets of instant noodles for 1,500 calories total and lose weight.
That would not be the best diet though, it would be unhealthy and lacking nutritionally.
You'd want to make sure you get veggies/lean meats/fruits in your diet.
