If it feels like protein is suddenly everywhere — protein-packed everything at the grocery store, protein goals built into every fitness app — that's because it genuinely is one of the most important levers for body composition, recovery, and long-term health available to us.
One of the biggest reasons protein is having a moment right now is the rise of GLP-1 medications. These medications can be effective tools for weight loss, but one well-documented side effect is a significant loss of lean muscle mass alongside fat loss — in some cases, as much as 25 to 40 percent of total weight lost. Without adequate protein intake and resistance training to counteract it, a meaningful portion of "weight loss" on these medications ends up being muscle people actually wanted to keep.
This isn't just a GLP-1 issue — it's relevant for anyone working on body composition. Protein is the raw material your body uses for muscle repair and growth. It keeps you fuller longer, which makes it easier to manage overall intake without feeling deprived, and it plays a significant role in metabolic health as we age. Most people, especially busy adults juggling work and family, are eating far less protein than they think they are, even when they believe they're eating "healthy."
General guidance for active adults tends to land somewhere around 0.7 to 1 gram of protein per pound of body weight per day, though individual needs vary based on goals, activity level, and whether someone is actively trying to build or preserve muscle. For most people, hitting that target consistently is more about planning than willpower — building a protein source into every meal rather than trying to "make up for it" at dinner.
Our nutrition coaching is built around this exact principle: strength training plus adequate protein is the combination that actually preserves and builds the muscle you want, whether your goal is fat loss, athletic performance, or simply aging well. We help members figure out realistic protein targets for their specific body and goals, and — just as importantly — how to actually hit those targets without living on chicken breast and rice for the rest of their lives.
If you're working on body composition goals — with or without medication support — pairing the right training with the right nutrition is what makes the results stick. Book a FREE No Sweat Intro at www.crossfitportclinton.com and let's build a plan that protects the muscle you're working for.
