Questions & Answers about Si vuelvo a engordar, hablaré con la nutricionista para cambiar mis porciones.

Why is it “Si vuelvo a engordar” and not “Si engordaré otra vez”?

In Spanish, after si (if) to talk about a real or likely future condition, you normally use the present indicative, not the future tense.

• Correct: Si vuelvo a engordar, hablaré…
  (If I put on weight again, I will talk…)
• Incorrect: Si engordaré otra vez, hablaré…

This is a standard pattern:

• Si tengo tiempo, te llamaré. – If I have time, I’ll call you.
• Si llueve, nos quedaremos en casa. – If it rains, we’ll stay home.

So: si + present, then future in the other clause. You almost never say si + future in this type of conditional sentence.

What does “vuelvo a engordar” literally mean? Is “vuelvo a” always “again”?

Literally, vuelvo a engordar is “I return to getting fat,” but the natural meaning is “I gain weight again / I put on weight again.”

The structure is:

• volver a + infinitive = to do [something] again

Examples:

• Volveré a intentarlo. – I’ll try again.
• Nunca volvió a llamarme. – He never called me again.

You could also say:

• Si engordo otra vez… – If I get fat again…

Both are fine; volver a + infinitive is very common and sounds natural.
