CKD Nutrition: How to Track Potassium, Phosphorus, and Protein on a Renal Diet
Chronic kidney disease nutrition is unlike any other therapeutic diet. Managing potassium, phosphorus, sodium, and protein simultaneously — with targets that shift as kidney function declines — requires tracking tools that no general health app has ever been built to provide. The GritLeanPulse Renal Diet screen tracks all four nutrients against your nephrologist-set targets in real time.

Autoimmune Elimination Diets: How to Track the AIP Protocol and Know When It's Working
The Autoimmune Protocol is one of the most restrictive elimination diets in clinical use — removing grains, legumes, nightshades, dairy, eggs, nuts, seeds, and all processed foods for an initial elimination phase. Without systematic tracking, it is nearly impossible to identify which foods are triggers and which are safe to reintroduce. The GritLeanPulse Autoimmune Diet screen was built for this.

GERD and Reflux: The Foods That Trigger Symptoms and How to Finally Track the Pattern
GERD affects more than 20% of adults and is one of the most common reasons people seek dietary guidance. Yet most food tracking apps have no way to log reflux symptoms alongside meal entries, identify timing patterns, or correlate trigger foods with symptom severity. The GritLeanPulse GERD & Reflux screen does all three.

Food Allergies and Intolerances: Why You Need a Tracker That Logs Reactions, Not Just Avoidances
Managing food allergies and intolerances is not just about avoiding trigger foods — it is about logging exposures, tracking reactions, documenting EpiPen use, and building the evidence your allergist needs to understand your pattern. Generic food diaries cannot do this. The GritLeanPulse Food Allergies screen was designed for the reality of living with a food allergy.

Liver Health and NAFLD: How Nutrition Tracking Can Reverse Fatty Liver
Non-alcoholic fatty liver disease affects roughly 1 in 4 adults globally and is closely linked to metabolic health, insulin resistance, and obesity — making it especially relevant for GLP-1 users and anyone in active weight loss. The nutrition changes that most reliably reduce liver fat are well-documented: calorie reduction, fructose elimination, and Mediterranean diet adherence. The GritLeanPulse Liver Health screen tracks all of them.

SIBO, FODMAP, and the Stress-Gut Connection: A New Way to Track
SIBO is one of the most under-tracked conditions in consumer health apps — despite affecting a significant portion of people with chronic bloating, gas, and gut discomfort. Understanding the FODMAP protocol, how to score compliance daily, and the stress-gut connection that most SIBO patients overlook is the difference between managing symptoms and actually resolving them. The GritLeanPulse SIBO & Gut Health screen brings all of it into one place.

Oncology Nutrition: How to Eat Through Chemotherapy, Radiation, and Beyond
Nutrition during cancer treatment is not the same as nutrition for general health. Chemotherapy, radiation, immunotherapy, and survivorship each create different physiological demands and nutritional priorities. Managing treatment side effects through food — maintaining muscle mass when nausea and taste changes make eating difficult, supporting immune function, preserving weight through active treatment — requires tools built specifically for oncology. The GritLeanPulse Oncology Nutrition screen adapts to your current treatment phase.

IBD, IBS, and the Bristol Scale: Why Generic Food Diaries Don't Work for Gut Conditions
Crohn's disease, Ulcerative Colitis, and IBS are distinct conditions with different mechanisms — yet most health apps treat them identically, or not at all. The Bristol Stool Scale, trigger food logging, flare status tracking, and condition-specific AI coaching are not optional when you're managing IBD or IBS. Generic food diaries are not just inadequate — they can actively miss the patterns that matter. The GritLeanPulse IBD & IBS Tracker was built for the specific reality of gut condition management.

Post-Bariatric Nutrition: The Most Underserved Problem in Health Apps
Every bariatric surgery type — gastric bypass, sleeve gastrectomy, adjustable gastric band, duodenal switch — creates different nutritional requirements that evolve through the months post-op. Protein-first eating, fluid tracking, supplement adherence (B12, calcium citrate, iron), and dumping syndrome management are the daily reality for post-bariatric patients. No general health app has been built to support this. The GritLeanPulse Post-Bariatric Nutrition screen is surgery-type-aware and phase-calibrated.

Cardiac Nutrition Done Right: The DASH Diet, Mediterranean Scoring, and What Your BP Numbers Actually Mean
The DASH diet is one of the most evidence-backed dietary interventions for cardiovascular health — but most people who are told to "eat DASH" have no way to track whether they're actually doing it. Serving targets for fruits, vegetables, whole grains, lean proteins, and sodium; a Mediterranean Diet Score; and blood pressure trend logging together give you the complete cardiovascular nutrition picture your cardiologist can't review with you between appointments. The GritLeanPulse Cardiac & Heart Diet screen brings all of it together.

Eating Disorder Recovery: Why Your Tracking App Might Be Making Things Worse
Calorie-counting apps are contraindicated for eating disorder recovery. Logging numbers, seeing deficits, and receiving weight-based feedback creates exactly the cognitive environment recovery needs to dismantle. What recovery-supportive tracking actually looks like — logging meals completed, urges experienced, coping skills used, and mood without any mention of calories, weight, or BMI — is almost entirely absent from the consumer health app market. The GritLeanPulse Eating Disorder Recovery screen was designed with that clinical reality at every step.

Diabetes Nutrition Tracking: Why Carbs Alone Aren't the Full Picture
Carbohydrate counting is a starting point for diabetes nutrition — not the full story. Glycemic load, post-meal glucose response, HbA1c trending, insulin dose correlation, and the interaction between meal composition and glucose outcomes are the data points that actually reveal how your nutrition is affecting your blood sugar control. The GritLeanPulse Diabetes Nutrition screen tracks all of them, supporting Type 1, Type 2, LADA, and gestational diabetes.

Celiac Disease and Nutrition: How to Finally Track Gluten Exposure the Right Way
A gluten-free diet toggle is not a Celiac tracker. People managing Celiac disease need to log gluten exposure events with portion and context, rate symptom severity across nine specific symptoms, document cross-contamination risk from shared fryers and surfaces, and see 14-day AI pattern analysis that identifies their personal gluten threshold and highest-risk meal settings. That is the level of specificity the Celiac community deserves — and what the GritLeanPulse Celiac & Gluten Tracker delivers.

NOVA 1 to 4: Why the Processing Level of Your Food Matters More Than the Calorie Count

Why 'Just Pick One Diet' Is Bad Advice — The Case for Combining Approaches

Testosterone After 35: What's Normal, What's Low, and What to Actually Do About It
Testosterone declines roughly 1-2% per year after age 30 — but that average hides enormous individual variation. Fatigue, declining strength, mood changes, and reduced libido can all reflect suboptimal testosterone, yet most men are told their levels are "normal."

The Male Hormone Panel: What Your Labs Actually Tell You About Energy, Libido, and Body Composition
Total testosterone is only one piece of a panel that most men have never seen interpreted correctly. Free testosterone, SHBG, LH, FSH, estradiol, prolactin, DHEA-S, cortisol, and PSA all interact — and the relationships between them often explain symptoms that any single number cannot.

Cortisol, Chronic Stress, and Body Composition: Why Stress Is Making It Harder to Lose Fat
Cortisol is not simply the "stress hormone" — it is a central regulator of metabolism, fat storage, muscle breakdown, and appetite. Chronically elevated cortisol from sustained psychological stress creates a hormonal environment that is almost directly opposed to fat loss. Here is the mechanism, the evidence, and the interventions that measurably lower cortisol and restore the hormonal conditions your body needs to change.

Male Depression Looks Different — and That's Why It Goes Undiagnosed
