βWeight loss isn't about shrinking yourself. It's about building a healthier, stronger, more confident version of you β one that lasts.β
Every other free weight loss app tells you to "eat less, move more." FitHer tells you what they don't: how to preserve muscle, navigate weight loss products, handle PCOS & menopause, and keep the weight off. All 100% free.
56.4% of American women try to lose weight each year (CDC NHANES) β yet over 80% regain it within 5 years. The reason isn't lack of willpower. It's that four critical facts are systematically ignored by most programs.
Without resistance training and adequate protein, 25-40% of every pound you lose comes from lean mass, including skeletal muscle (Metabolism, 2024; BMJ Open Sport Exerc Med, 2025). This is especially severe for GLP-1 users, where ~30% of weight loss can be lean tissue (PMC, 2025). Since each pound of muscle burns ~6 calories/day at rest versus ~2 for fat (Wang et al., AJCN), muscle loss directly slows your metabolism β setting you up for rebound weight gain.
What FitHer does: Protein-first meal plans (20+ high-protein recipes), strength training programs designed to preserve muscle, and dedicated muscle preservation guidance in our Wellness Companion.
A landmark meta-analysis of 29 long-term studies found that more than half of lost weight returns within 2 years, and over 80% is regained by year 5 (Hall & Kahan, 2018, Medical Clinics of North America; Anderson et al., 2001, Am J Clin Nutr). The body actively fights weight loss: metabolic rate drops 15-20% more than predicted for the new body weight (Fothergill et al., 2016, Obesity), while hunger hormones like ghrelin surge 20-30% above baseline. Most programs teach you to lose weight β none teach you how to keep it off.
What FitHer does: Post-weight-loss maintenance strategies, metabolic adaptation education, and sustainable habit-building β all free, all evidence-based.
PCOS affects 8-13% of women and increases insulin resistance by 35-40%, making weight loss disproportionately difficult (Teede et al., 2023, Int'l PCOS Guideline; Diamanti-Kandarakis & Dunaif, 2012, Endocr Rev). Perimenopause brings an average 1.5 kg/year weight gain driven by estrogen decline (Davis et al., 2012, Climacteric). Yet over 70% of nutrition and exercise science has historically been conducted on men (Costello et al., 2014, Sports Med) β meaning most "universal" advice was never tested on female bodies.
What FitHer does: Addresses PCOS, perimenopause, hormonal contraception, and menstrual cycle effects directly. Every recipe, workout, and guide is designed for female physiology β not adapted from male research.
Over 15 million Americans now use prescription weight loss medications (KFF Health Tracking Poll, 2024), with women accounting for 76% of new prescriptions (IQVIA, 2024). Despite this massive adoption, there is no major free, science-backed resource telling these millions of women what to eat, how to exercise, and how to manage side effects while on medication. Studies confirm that without structured lifestyle support, GLP-1 users lose significantly more lean mass (Metabolism, 2024; PMC, 2025).
What FitHer does: The web's first completely free, comprehensive companion resource for women using weight loss products β meal guides, anti-nausea recipes, muscle-preserving workouts, and post-medication maintenance plans.

Not another calorie counter. Not another "eat less" app. Here's what we actually do.
Every claim on this site is backed by peer-reviewed research β not influencers, not fads. Mifflin-St Jeor for calories, US Navy for body fat, MET Compendium for exercise, ACSM for workouts. References included.
PCOS, menopause, hormonal contraception, menstrual cycle effects β these are not side notes. They're central to how women lose weight, and we address them directly.
Up to 40% of weight lost can be muscle (Harvard Science Review, 2026). Muscle loss = slower metabolism = weight regain. Our protein timing strategies and strength workouts are designed to protect your muscle.
