Research
Look up the research on best source of protein
Short version: the “best” protein source depends on what you’re optimising for — muscle protein synthesis, total health, digestibility, or vegan practicality. Whey usually wins for pure muscle efficiency, but a well-built soy/pea blend does the job just fine.
🔬 Look up the research
🔬 Research✦ Premium
For muscle gain, whey is still the best-supported single protein source, but the gap versus soy and pea is smaller than supplement marketing would like when total protein and leucine are adequate. For overall health, the best choice is usually the protein you can eat consistently inside a cardiometabolically solid diet; among these, soy and pea are strong plant options, while animal proteins work well for hypertrophy but vary more in broader health profile depending on source and processing.
Muscle gain

Whey has the strongest direct evidence base for hypertrophy, but matched trials suggest soy and pea can land very similarly when total daily protein and leucine are high enough.

Best plant option

Soy has the deepest plant-based evidence base, while pea looks promising in newer head-to-head trials rather than just theory.

Health trade-off

For overall health, whole-diet quality matters more than brand loyalty — minimally processed soy and pea usually beat turning your diet into a shrine to protein powder.

🎯
For you specifically

For you, with a vegan pattern and a fat-loss goal while training hard, the useful bit is this: you do not need whey to build muscle. Soy is the most established plant option, and pea looks very solid too when your total protein intake is high enough across the day.

Real numbers, not guesses

She checks
the label.

“How many calories in a KFC Zinger?” Arlo looks it up in real time, shows you every source, and gives the honest range — then you just say log it. Other apps guess. Arlo shows her working.

Memory you can trust

She never
forgets.

Most AI remembers approximately. For macros, approximate is useless. Arlo has total recall of everything you've logged — so the trends, the streaks, the averages are real numbers you can actually act on.
