Nutrition science, macro targets, and how to get the most from YourMealPlanRX.
There is no single "best" macro split — the optimal percentages depend on your health goals, activity level, and any existing conditions. That said, research consistently points to a few evidence-based frameworks:
| Framework | Protein | Carbs | Fat | Best for |
|---|---|---|---|---|
| Standard Balanced | ~30% | ~40% | ~30% | General health maintenance |
| Weight Loss | 35–40% | 30–35% | 25–30% | Fat loss while preserving muscle |
| T2D / Blood Sugar | 30–35% | 25–35% | 30–40% | Blood glucose control (Type 2 Diabetes) |
| Mediterranean | 15–20% | 45–50% | 30–35% | Heart health & longevity |
| Athletic / Muscle Gain | 25–35% | 40–50% | 20–30% | Building muscle, fueling training |
Hitting the numbers with ultra-processed foods won't give you the same outcomes as hitting them with whole foods. The type of each macro matters enormously:
Open the app → tap ⚙ Goals on your home dashboard → set your calorie target and macro percentages. The planner tracks your macros in real time against those targets. If you're not sure where to start, the Standard Balanced split (P30 / C40 / F30) is a solid default for most healthy adults.

Probably fewer than you think — and that's the whole reason a personalized meal plan works.
Research consistently shows that about 20–30 foods make up roughly 80% of what most people actually eat. It follows a Pareto-like pattern: a small number of staples dominate the diet, and everything else is occasional variety.
For the average adult (~2,200 cal/day), calories typically break down as: breakfast 300–500 · lunch 500–700 · dinner 700–900 · snacks 200–400.
People managing Type 2 Diabetes, high blood pressure, or high cholesterol tend to eat an even smaller rotation than average — they naturally gravitate toward "safe" foods they know won't cause a spike or a problem, and they stick with those. The challenge is those safe foods aren't always optimized for their condition.
That's exactly what YourMealPlanRX is built for: taking the 15–25 foods you already love and showing you how to prepare and portion them to work with your health goals — not against them.
