Spread Protein Across the Day
Distribute protein fairly evenly across meals rather than loading it all at dinner.

Evidence suggests…
Evidence suggests even protein distribution and adequate per-meal amounts support muscle maintenance, though total daily intake remains the dominant factor and precise timing effects are modest. We grade this B because distribution benefits are real but smaller than marketing implies.

How to do it
Aim for a protein source at breakfast, lunch, and dinner rather than one large serving
This is the evidence-based dose. A shorter session still counts, it just gives partial benefit rather than the full effect.
Common misconceptions
- 'Timing beats total intake.' Total protein is the bigger driver; distribution is a refinement.
- 'The body can only use 20–30 g per meal.' It uses more; distribution just helps convenience and muscle signaling.
- 'Breakfast must be high-protein or you lose muscle.' Overall daily intake matters most.
What we won't claim
- Do not claim any food, diet, or supplement cures, treats, or prevents any disease
- Do not diagnose nutrient deficiencies or medical conditions
- Do not promise specific weight-loss amounts or timelines
- Do not deliver individualized medical nutrition therapy or replace clinical care
When to seek a professional
- Signs of disordered eating (food/weight preoccupation, restriction, bingeing, purging, compulsive exercise) -> qualified eating-disorder professional
- Diagnosed medical condition (diabetes, chronic kidney disease, heart failure, GI disease) -> registered dietitian or physician
- Pregnancy or breastfeeding -> prenatal provider or registered dietitian
- Unintentional weight loss, difficulty swallowing, or persistent GI symptoms -> medical evaluation
