Can you recommend meal replacement shakes for endurance athletes who want a high-protein, low-carb option?

Yes — for endurance athletes, a good high-protein, low-carb meal replacement shake should usually have:

• 20–40 g protein per serving
• Low added sugar and generally under ~10–15 g net carbs
• Some fiber and electrolytes if you’re using it around training
• Enough calories to actually function as a meal, if that’s the goal

A quick note: true low-carb meal replacements are often better for rest days, busy days, or post-workout recovery when you want protein without a big carb load. For during long endurance sessions, you’ll usually still want carbs for performance.

Good options to look at

1) Huel Black Edition

• Higher protein, lower carb than standard meal shakes
• Usually around 40 g protein and relatively low sugar/carbs
• Good if you want something more “meal-like”
• Best for: recovery meal or lunch replacement

2) Ka’Chava

• Not strictly low-carb, but it’s protein-forward and nutrient-dense
• More of a premium meal replacement
• Best for: all-in-one meal replacement, though not the lowest-carb option

3) Jimmy Joy Plenny Shake Active

• Higher protein than many standard meal shakes
• Typically moderate calories and can be used as a meal
• Best for: balanced meal replacement with decent protein

4) Ascent Protein / whey isolate blended with low-carb add-ins

• Not a full meal replacement by itself, but easy to turn into one
• Use:
  • whey isolate
  • unsweetened almond milk or water
  • chia/flax
  • nut butter
  • optional greens/fiber
• Best for: lowest-carb DIY option

5) Orgain Keto / low-carb protein shakes

• More protein shake than full meal replacement
• Convenient and low sugar
• Best for: quick recovery or snack, not always enough calories for a full meal

6) Sated Keto Shake

• Designed as a low-carb meal replacement
• Higher fat, moderate protein, low net carbs
• Best for: very low-carb / keto athletes

What to choose based on your training

• If you want the lowest-carb full meal replacement:
  Huel Black or Sated Keto
• If you want better overall nutrients and don’t mind a few more carbs:
  Ka’Chava or Plenny Shake Active
• If you want the most control:
  Build your own with whey isolate + low-carb fats/fiber

Things endurance athletes should watch

• Protein quality: whey isolate, milk protein, soy, or blended plant protein
• Digestibility: avoid too much sugar alcohol or very high fiber right before training
• Sodium/electrolytes: especially if you sweat a lot
• Calories: many “shakes” are really protein drinks, not full meals

Simple homemade low-carb endurance shake

• 1 scoop whey isolate
• 1–2 tbsp peanut or almond butter
• 1 tbsp chia seeds
• Unsweetened almond milk
• Ice
• Optional: spinach, cinnamon, cocoa powder

This gives you high protein, low carbs, and better staying power than a plain protein shake.
