Achieving visible abdominal muscles is one of the most sought-after fitness goals among men. While exercise plays a crucial role, nutrition is the foundation for revealing those coveted six-pack abs. The truth is that abs are made in the kitchen – no amount of crunches will reveal them if they’re hidden under a layer of body fat.
This comprehensive guide will walk you through the optimal diet strategy to lose belly fat and develop well-defined abdominal muscles. We’ll cover macronutrient ratios, specific foods to eat and avoid, meal timing strategies, and how to combine nutrition with training for maximum results.
Understanding Abdominal Muscle Development
