Evidence-Based Meal Planning for Fat Loss, Muscle Gain and Longevity

Plan your meals, calculate your fasting window, discover high-protein air fryer recipes, and use science-backed nutrition tools to make better decisions.

— The Framework
Three Pillars of Evidence-Based Nutrition
Every tool and resource in this hub is built around these three principles, backed by peer-reviewed research.
01
Protein First
Research consistently shows that 1.6–2.2g of protein per kg of body weight per day is optimal for muscle protein synthesis and fat loss. Every tool in this hub starts with protein targets.
02
Calorie Awareness
Total energy intake drives fat loss and gain. The meal planner calculates your TDEE using the Mifflin-St Jeor equation, the most validated formula for sedentary to active individuals.
03
Meal Timing & Fasting
Intermittent fasting improves metabolic markers and simplifies calorie control. The fasting calculator helps you find the right protocol without guesswork.

Tools That Make Fitness Nutrition Practical
Chosen for meal prep efficiency, durability, and compatibility with high-protein cooking. Affiliate links — we earn a commission at no cost to you.
Air Fryer
Best Air Fryers for Fitness Meal Prep
Air frying reduces oil use by up to 75% vs deep frying while keeping protein-dense foods moist and flavourful — ideal for chicken breast, salmon, and egg-based meals.
Best for: High-volume meal prep, 4–6 litres capacity, easy cleaning.

Kitchen Scale
Best Digital Kitchen Scales
Precise food weighing is the single biggest predictor of macro accuracy. A 0.1g precision scale removes all guesswork from portioning protein and carb sources.
Best for: Macro tracking, baking, portioning supplements and powders.

Meal Prep
Best Meal Prep Containers
Portioned containers make hitting macros effortless across the week. Glass containers are preferred for reheating without leaching plasticisers into food.
Best for: Weekly batch cooking, fridge/freezer storage, portion control.

Oil Control
Best Oil Sprayers
Controlling oil spray means controlling fat calories. A quality sprayer delivers a thin, even coat — saving 50–80 kcal per meal compared to pouring.
Best for: Air fryer cooking, salads, non-stick pan cooking.

Cooking Accuracy
Best Meat Thermometers
Overcooking protein makes it dry and unpalatable — the biggest reason people stop meal prepping. An instant-read thermometer guarantees perfect doneness every time.
Best for: Chicken, salmon, beef — any high-protein protein source.

Protein Tracking
Best Protein Shakers
A quality shaker with a mixing ball eliminates clumping — making post-workout and between-meal protein hits effortless. Insulated versions keep shakes cold for hours.
Best for: Post-workout whey, casein before bed, meal replacement shakes.

Electrolytes
Fasting Electrolyte Supplements
Electrolyte depletion is the main cause of fasting fatigue and headaches. Zero-calorie electrolyte mixes allow you to maintain your fast while staying hydrated and alert.
Best for: Extended fasts (18h+), OMAD, low-carb and keto protocols.

Appetite Control
Black Coffee & Green Tea
Caffeine suppresses appetite and enhances fat oxidation during fasted states. Studies show black coffee does not break a fast and may amplify its metabolic benefits.
Best for: Morning fasted window, pre-workout during fasting periods.

Breaking the Fast
High-Protein First Meal Tools
Breaking your fast with high-protein, high-fibre foods prevents blood sugar spikes and controls appetite for the rest of the eating window.
Best for: First meal planning, portion control post-fast.
