Protein in Dal (Lentils)

Protein by portion size

How much dal (lentils) to hit your protein target?

Phillips & Van Loon 2009 (JISSN) established 0.4 g/kg per meal as the per-meal threshold to fully stimulate muscle protein synthesis — roughly 25–40g for most adults. To hit those targets purely from dal (lentils):

• 275g of dal (lentils) for 25g protein (~319 kcal)
• 440g of dal (lentils) for 40g protein (~511 kcal)
• Per 1g of protein from dal (lentils): 12.8 kcal

What this protein density means

For perspective, the highest-density protein whole foods cluster around 15–19g of protein per 100 kcal: chicken breast 18.8, white fish 16–17, Greek yoghurt 17 (non-fat), tuna 15. Medium-density sources (5–12 g/100kcal) include eggs, beef, salmon, tofu, and lentils. Below 4g/100kcal, foods are primarily carb or fat sources with incidental protein. Dal (Lentils) at 7.8g/100kcal is a moderate contributor — useful as part of a varied diet but you'll need denser sources to consistently hit 1.6–2.2 g/kg targets.

Frequently asked questions

How much protein is in dal (lentils)?

Dal (Lentils) contains approximately 18g of protein per 1 cup cooked dal (230 kcal). Per 100g, that's 9.1g of protein. The protein-per-calorie density is 7.8g per 100 kcal — classified as moderate.

Is dal (lentils) a good source of protein?

Dal (Lentils) contributes some protein per serving but isn't a high-density source. It works well as part of a varied diet but you'd need other sources to hit typical protein targets of 1.6 g/kg body weight (Morton 2018 BJSM). For comparison: chicken breast delivers 18.8g protein per 100 kcal; Greek yoghurt 17g; eggs 8g; lentils 8g; rice 2g.

How much protein do I actually need per day?

The Morton 2018 meta-analysis in the British Journal of Sports Medicine (49 randomised trials, 1,863 subjects) established 1.62 g/kg of body weight per day as the dose-response plateau for muscle gain from resistance training. For active adults during fat loss, the Helms 2014 review recommended 1.8–2.2 g/kg of total body weight to preserve lean mass. The old RDA of 0.8 g/kg is a population minimum, not an optimum. For a 70 kg adult, evidence-based daily protein targets are 112–154g.

How is protein quality measured beyond grams?

The Digestible Indispensable Amino Acid Score (DIAAS) is the modern protein quality measure, evaluating both amino acid profile and digestibility against human requirements. Animal proteins — whey, casein, eggs, chicken, fish — score 1.0+ (complete and highly digestible). Most plant proteins score below 1.0: pea ~0.82, rice ~0.59, soy ~1.0 (the plant exception). For vegans, combining sources across the day (legumes + grains, soy + nuts) produces a complete amino acid profile and offsets the digestibility gap by targeting the upper end of intake ranges.
