Frequently Asked Questions

Almost identical: 132 vs 116 kcal per serving. For weight loss, base your pick on which keeps you fuller (Lentils has more fiber) rather than calories.

Which has more protein?

Tuna wins on protein with 28g per serving versus 9g for lentils. Per calorie, that's 21.2g protein/100 kcal vs 7.8g protein/100 kcal — useful context when you're aiming for a high-protein, controlled-calorie day.

Both are protein sources, so stacking them in one meal duplicates macros instead of balancing them. Rotate across meals or pair each with a different macro category (carbs and a fat source).
