Yes. 120 calories are 120 calories. Whether they come from dietary fats, protein or carbs does not matter and if you don’t use them, they’ll be stored as fat reserves by your body for later use.
Usually, most of the calories from fiber supplements come from the sugar that is added for taste. Better that than the zero calories fake sugar that will mess up your body to no end. At least, if you eat 360 calories extra, you can still use those by working out more.
Make sure that you still eat enough to cover your Basal Metabolic Rate or your body will adapt to a low caloric intake and lower your metabolism, making it very hard for you to use your body fat. And then, as soon as you would eventually start eating normally again, you would make body fat very easily, because you would have a lower metabolism and therefore regain all the weight you lost and keep going up, unless you exercise A LOT.
Also, as you’re younger than 21, you need to eat more when having a growth spurt so you don’t stunt your growth (you get ravenous).
655 + (4.35 x weight in pounds) + (4.7 x height in inches) - minus (4.7 x age in years)
About another answer you got...do not eat 30% of dietary fats, especially if you have digestive problems, and you’re trying to lose weight and you need more carbs and protein for exercising and getting in shape. Your organs only need 20% of dietary fats, the good kind of fats, coming from plants food or fish (olives, olive oil, avocado, nuts...). A person not on a diet can have up to 25% of dietary fats (even if 5% of those are coming from animal source...lean meat , low fat dairies or eggs).
Have 20% of dietary fats, 20% of protein (so you can build up muscle mass) and 60% or carbs (so you get plenty of energy to exercise).
Also be aware that the nutrition fact labels are based on a 2,000 calories diet (they had to choose a number...) so you have to adjust all the percentages to fit your personal calorie intake.
Even then, they will choose the highest requirements. Like you need at least 460 to 920mg of sodium (depending on your gender and weight). You can use more if you’re using sodium to compensate for diuretic food. Now the maximum sodium intake for a person eating 2,000 calories would be 2,400mg (about one tsp of salt), above that, you put your health in danger. Unfortunately, a lot of people go above that if they eat salty food and processed food, restaurant food (sodium is used for conservation). Just a can of V8 has 60mg per ounce (one glass would be 480mg).
I don’t know your age/weight/height but let’s say a 15 years old teenage girl, who would be 5’6 tall and weigh 146lbs would have a 1,528 calories BMR and only eat that because she wants to lose weight, using exercising (3,500 calories of exercising for each pound of body fat) as to not mess up her metabolism. She would only eat more when having a growth spurt. Her maximum sodium intake would not be 2,400mg but 1,833mg...2,000 calories diet divided by 2,400mg = 0.8333 and 1,528 calories diet divided by 0.8333 = 1,833mg.
A 60 years old, 5’5 and 120lbs woman with a 1,200 calories BMR would have to multiply the food labels numbers by 0.6 (2,000 x 0.6 = 1,200).
A 22 years old, 6’4 and 260lbs man (like a football player) with a 2,500 BMR would have to multiply the food labels numbers by 1.25 (2,000 x 1,25 = 2,500).
That football player could also eat up to 3,000mg of sodium (2,500 calories divided by 0.8333 = 3,000mg, surpassing recommended maximum requirements of 2,400mg).
Multiply by 0.6 (1,200 calories diet), 0.65 (1,300 calories diet), 0.7 (1,400 calories diet), 0.75 (1,500 calories diet), 0.8 (1,600 calories diet), etc...
