🥩PROTEIN GOALS FOR WEIGHT LOSS CLIENTS ON TIRZEPATIDE or SEMAGLUTIDE

Why it matters:  Tirzepatide works by reducing appetite and slowing digestion — leading to fast, powerful fat loss. But without enough protein, you may also lose valuable muscle mass, which can lower your metabolism and leave you feeling weak, tired, or flabby even as the scale drops.

Protein helps protect lean mass, stabilize energy, support hormone health, and keep you feeling full — it’s your top nutritional priority on this journey.

🔢 How Much Protein Do You Need?

  • General Goal:
    Aim for 0.8 to 1.0 grams of protein per pound of body weight per day.

  • If you carry more body fat (BMI 30+):
    Use your ideal body weight (based on height/frame) to estimate your target.
    Example: If you weigh 220 lbs but your goal/ideal weight is 160 lbs, aim for 130–160 grams of protein/day.

  • If you’re active or strength training:
    Stick to the higher end to protect and grow muscle.

  • If you’re new to protein tracking or have a low appetite:
    Start with a minimum of 100g/day, then build up over time.
