Quick answer: Comparing Unicity Feel Great System vs Isagenix for weight loss, cleansing, cost, and long-term results. Honest comparison of both metabolic programs.

Quick Answer: Isagenix uses periodic "cleanse days" and meal replacement shakes to create caloric restriction. The Unicity Feel Great System uses intermittent fasting + Unimate + Balance to fix insulin resistance without meal replacement or cleansing. The Feel Great System costs ~$159/month vs Isagenix's $300–450/month, and carries a 90-day money-back guarantee vs Isagenix's 30-day policy.

The Company Backgrounds

Unicity International was founded in 2001 and focuses on metabolic health. It has 23+ years of clinical research and holds the distinction of having two products — Unimate and Unicity Balance — listed in the Prescribers' Digital Reference (PDR), the same reference used by US physicians. Both products are patented.

Isagenix was founded in 2002 and focuses on nutritional cleansing and meal replacement. Its products are widely distributed through an MLM structure. Isagenix holds no PDR listings for its core products.

How Each System Works

Isagenix 30-Day System

Isagenix combines:

  • IsaLean shakes (meal replacements, ~240 cal each)
  • Cleanse for Life (liquid supplement used on 2 "cleanse days" per week of 400–600 cal total)
  • Snacks, accelerators, and optional add-ons

The mechanism is primarily caloric restriction, with "cleanse days" functioning as very low calorie fasting days.

Feel Great System

The Feel Great System uses:

  • Unimate in the morning fasting window — appetite suppression, mental clarity, extended fast
  • Unicity Balance before meals — glucose and insulin spike blunting
  • 16:8 intermittent fasting — no meal replacement, no cleanse days

You eat real, unrestricted food during an 8-hour window. No shakes, no cleanse days, no special foods required.

Side-by-Side Comparison

Factor Feel Great System Isagenix
Monthly cost $169 (member price) ~$300–450 USD
Mechanism Insulin control + intermittent fasting Calorie restriction + nutritional cleansing
Meal replacement? No Yes (1–2 shakes/day)
PDR listed? Yes No
Money-back guarantee 90-day 100% 30-day
Cleanse days required? No Yes (2 days/week)
Social eating compatible? Yes Moderate (shake dependency)

The Cleanse Question

Isagenix's "cleanse days" are essentially very low calorie days (400–600 kcal) marketed as detoxification. Mainstream nutrition science does not support the concept of product-based detoxification — the liver and kidneys perform this function continuously. However, the caloric restriction on cleanse days does produce fat loss.

The Feel Great System achieves similar metabolic benefit through the 16-hour fasting window daily — a more sustainable and less disruptive approach than periodic extreme calorie restriction.

Cost: A Significant Difference

Isagenix's 30-day system with shakes, cleanse, and recommended supplements typically runs $300–450/month. The Feel Great System is$169/month at member pricing — roughly half to one-third the cost. Over a 90-day trial, that is a $400–900 difference.

Which Should You Choose?

For clinical credibility (PDR listings), cost (half the price), lifestyle flexibility (no shakes, no cleanse days), and guarantee length (90 vs 30 days) — the Feel Great System is the stronger choice.

Isagenix may suit those who prefer packaged shake convenience or have responded well to Isagenix in the past. But for a metabolically grounded, affordable, flexible protocol — the Feel Great System is hard to beat.

Metabolic Flexibility and Long-Term Implementation Framework

Whether you are evaluating Unicity from a scientific, regulatory, or business perspective, long-term success with the Feel Great System comes down to daily consistency and metabolic flexibility. Modern dietary patterns characterized by frequent grazing and refined carbohydrates keep circulating insulin levels elevated throughout the day, preventing efficient fat oxidation and contributing to afternoon energy crashes.

By pairing Unimate (a purified yerba mate extract standardized for chlorogenic acids and theobromine) in the morning with Unicity Balance (a patented viscous soluble fiber matrix with plant phytosterols and micronutrients) before your largest meal, the 16:8 time-restricted eating protocol becomes practical and sustainable without extreme calorie deprivation.

Actionable 90-Day Protocol & Compliance Checklist

For customers and independent Unicity distributors alike, following evidence-based best practices ensures a reliable experience:

  • The 10-to-15 Minute Pre-Meal Window: Always mix one packet of Balance with 8 to 10 ounces of cold water, shake vigorously in a shaker bottle, and drink immediately 10 to 15 minutes before your main meal so the viscous fiber gel forms properly in the stomach.
  • Optimal Daily Hydration: Soluble fiber matrices bind with water in the digestive tract. Aim for at least 64 to 80 ounces of water throughout the day to support digestive comfort and nutrient transport.
  • Microbiome Adaptation Period: When increasing prebiotic soluble fiber intake, mild digestive adjustment during the first 5 to 7 days is normal. Pairing the protocol with whole proteins and non-starchy vegetables supports smooth adaptation.
  • Objective 90-Day Tracking: Track progress across multiple markers—morning mental clarity, afternoon satiety, waist circumference, and routine lab markers discussed with your physician—backed by the official 90-day money-back guarantee.

Step by step

  1. Morning Fasting: Start your day with Unimate to support GLP-1, boost energy, and extend your fat-burning window.
  2. Pre-Meal Balance: Take Unicity Balance 5-10 minutes before your first meal to reduce glucose spikes.
  3. Healthy Eating Window: Enjoy your first meal and keep a consistent eating window (typically 8 hours).
  4. Second Meal: Take Unicity Balance again before your second meal to close out your eating window.
