Shredding? Work with a coach who knows how to optimize lean protein for fat loss.

Why Prioritize Low-Fat Protein During a Cut?

When you're in a cutting phase, your primary goals are clear: reduce body fat while maintaining as much lean muscle as possible. The problem? You’ve got fewer calories to work with.

That’s why low-fat protein sources are so valuable. They deliver high-quality protein with minimal calories from fat, giving you:

More room for carbs and veggies
Easier macro control
Greater satiety and fullness
Better muscle retention during calorie deficits

Let a coach help you master cutting macros

Generally speaking, a low-fat protein source contains 3g of fat or less per serving and offers a high protein-to-fat ratio—typically 10:1 or better.

For lifters on a cut, this means:

Maximizing protein per calorie
Avoiding hidden fats (like in ground meats or processed foods)
Choosing lean cuts and low-fat versions of staples
