Ideally? Di kailangan mag-supplement. Malimit mas mahal for the practical effects on your health. Also by definition, they are supplementary to a healthy diet & exercise. Di ka pa nage-exercise? Unahin mo muna yun bago whey protein. Di lalakas yung katawan mo kung di mo gagamitin. Wanna lose weight? No supplement will burn fat better than a 500 kcal deficit per day. Mas mura pa iwasan ang junk food.
Trying to stick to/adhere to a diet is a different story. It takes weeks of setting & hitting goals before you gain the habit of eating healthy. For this, consider some supplements to keep you on track:
diet soda. Yes, I consider it a supplement. It's a literal blend of chemicals that satisfy your sweet tooth without the calories of regular soda, juice, or other sweets. Consume liberally.
protein powder (whey, soy, milk, etc.). Classic "gymbro" supplement, but it's just convenient protein. Madalas mahal at hassle abutin yung protein targets mo. Protein powders are super helpful.
coffee or tea. Energy boosters & appetitte suppresants, but use in moderation. Masasanay yung katawan mo pagtagal, at masisira yung tulog mo kung inabuso.
