You're doing the hard part. You're losing the weight. But here's what no one tells you: not all weight loss is created equal. When you lose weight fast on a GLP-1, muscle can disappear right alongside the fat. And muscle is the engine — it's your strength, your metabolism, your energy, the body you're actually working toward. Lose it, and the scale wins while you lose. Muscle Guard is built for one mission: keep your muscle while you lose the fat. Think of it as the coach in your corner for the whole journey — tracking what matters, nudging you at the right moments, and turning "am I doing this right?" into "I've got this." What Muscle Guard does for you: - Track the right things — Log weight, protein, strength, and energy in seconds. See the full picture, not just a number on a scale. - Hit your protein, every day — Personalized targets that make sure your body has what it needs to hold onto muscle. - Stay strong, simply — Quick, doable strength prompts designed to fit a real life, not a gym rat's. - See your progress, feel the momentum — Visual trends that prove the work is paying off and keep you going on the tough days. - Your coach, always on — Smart, encouraging guidance tuned to where you are in your journey. This isn't a diet. It's not another guilt machine. It's the tool that makes sure the weight you lose stays lost — and the strength you build stays yours. Lose fat. Keep your muscle.
