Congratulations — you've made a powerful decision.
Starting GLP-1 therapy is a big step, and the medication is only part of the story. This Quick Start Guide covers the essentials to help you avoid the most common early pitfalls and feel your best from day one.
For a fully personalized 12-week plan with custom meals, workouts, and weekly accountability, explore our GLP-1 360 Program.
What you need to know
GLP-1 medications (like semaglutide and tirzepatide) mimic a natural gut hormone to reduce appetite, slow digestion, and smooth out blood sugar. Most clients feel a noticeable drop in "food noise" within the first 1–2 weeks.
- First 2–4 weeks: expect lower appetite, earlier fullness, and possible mild side effects as your body adapts.
- Most common side effects: nausea, constipation, fatigue.
- Support matters: hydration, protein, and the right supplements dramatically improve how you feel.
Survival guide
Adjustment
Top 3 tips for managing nausea:
- Eat small, bland, protein-forward meals
- Avoid greasy, fried & very sweet foods
- Sip ginger or peppermint tea between meals
Hydration: 80+ oz water/day
Movement: 30-min walk daily
Finding Your Rhythm
- Protein first at every meal (aim 30g+)
- Small, slow meals — 20–30 min each
- Don't drink with meals
- Track how you feel, not just the scale

Eat to protect muscle & energy
GLP-1s shrink hunger — which means you must be intentional about what you eat to avoid muscle loss and fatigue.
- Protein: 0.7–1.0 g per lb ideal body weight
- Hydration: 80–100 oz/day
- Fiber: 25–35 g/day
5 non-negotiable rules
- Protein first, every meal.
- Eat slowly — 20–30 min per meal.
- Small portions — your stomach empties slower.
- Don't skip meals — even when not hungry.
- Hydrate between meals, not during.
Lift to keep what you've built
Without resistance training, up to 30–40% of weight lost on GLP-1 can come from muscle. A simple starter rhythm:
- 3× per week strength training (full-body)
- Daily steps: start at 5,000 → build to 10,000
- 1–2× per week light cardio or active recovery
