Frequently Asked Questions

How much protein do I need per day?expand_more

It depends on your body weight and goal. General guidelines: sedentary maintenance is about 0.8–1.0 g per kg of body weight; active people and general fitness 1.2–1.6 g/kg; building muscle 1.6–2.2 g/kg; and fat loss while preserving muscle 1.8–2.4 g/kg. For a 70 kg active adult that is roughly 84–112 g of protein a day.

Is more protein always better?expand_more

No. Beyond roughly 2.2–2.4 g/kg there is little additional muscle benefit for most people, and very high intakes mainly add calories. Spreading protein across 3–4 meals (around 20–40 g each) is more effective for muscle synthesis than one large serving.

What are good protein sources in Singapore?expand_more

Affordable, widely available options include eggs, chicken breast, fish, tofu and tau kwa, tempeh, Greek yoghurt, milk, edamame, dhal, and lean pork. Hawker choices like sliced fish soup, yong tau foo with more protein items, or chicken without skin are reasonable. Whey or soy protein powder is a convenient top-up if you struggle to hit your target from food.

Is high protein safe for my kidneys?expand_more

For people with healthy kidneys, higher-protein diets within the ranges above are generally considered safe. However, if you have chronic kidney disease, diabetes affecting the kidneys, or are pregnant, your needs differ and you should follow a doctor's or dietitian's advice rather than this general guideline.
