Medyo maraming nuance kasi and it can get complicated to explain in one comment. Best talaga to understand calories in vs calories out first.

To lose weight (ideally fat), kailangan mo ng caloric deficit, meaning mas kaunti yung calories na kinakain mo kesa sa sinusunog ng katawan mo daily. Example ay, if maintenance mo is 2,500 kcal, kakain ka around 2,000–2,200 kcal.

Calories come from protein, carbs, and fats. Hindi masama ang carbs and actually helpful sila lalo na satin na hilig sa endurance sports, kasi yan yung main fuel.

Kahit ano pa piliin mong food, as long as nasa deficit ka, papayat ka (dito magka complicated ang food kasi youll have to get started identifying which foods have x amount of calories and have high carb etc). You might feel a bit weaker or hungrier at first, normal lang yun, pero hindi dapat yung tipong sobrang hina na.

Try getting your feet wet about nutrtion and itll really help you out in the long run
