From the man who lost 129 lbs at age 55
Weight Loss Is Math,
Not Magic.
I spent 30 years trying every diet. Then I found the one equation my body actually runs on. I lost 129 pounds in 260 days. Now I teach it in 30.

You Are Not Broken.
You Are Just Guessing.
You have tried the diets. Keto. Weight Watchers. Noom. Intermittent fasting. They all worked - for a while. Then they stopped. And you blamed yourself. You thought you lacked discipline or willpower or some magic gene that thin people have.
Here is what nobody told you: every diet you have ever tried was built on the same math. Calories in, calories out. The equation is not complicated. But nobody ever showed you YOUR equation - the specific number of calories your body burns just existing. Your 'coma calories.' The baseline everything else builds on.
Without that number, every diet is a guess. And guessing is why the scale feels random, why two good weeks end in a 3-pound spike that makes you quit, and why you have spent years feeling smart about everything except this one thing.
You count calories but never know if the number is right
The scale goes up after a good week and you do not know why
Exercise apps tell you that you burned 800 calories (you did not)
The Equation That Changes Everything
It is called the Mifflin-St Jeor equation. It has been clinically validated for 35 years. And it takes 30 seconds to calculate.
BMR = 10 x weight(kg) + 6.25 x height(cm) - 5 x age - 161 (women) or + 5 (men)BMR x 1.2 = Your Daily Baseline (TDEE)This estimate is accurate within 10% for approximately 8 out of 10 people.
You do not need to memorize this. The calculator does the math for you. What matters is understanding these three steps:
Calculate
Your BMR is what your body burns doing nothing. Lying in bed. Not even digesting food. Alan calls these your 'coma calories.' Multiply by 1.2 and you have your daily baseline. Every calorie plan starts here.
Track
Once you know your number, the math is simple. Eat below it, the scale goes down. Eat above it, the scale goes up. No forbidden foods. No meal plans. No one telling you what to eat. Just math.
Trust the Math
The scale is a lagging indicator - like a bank statement that takes a few days to update. When you do the math right and the scale bumps up 2 pounds, you do not panic. You know it owes you. Alan calls this your 'Scale Payday.' It always comes.
I Lost 129 Pounds at Age 55.
No Secrets. Just Math.
On March 15, 2017, I stepped on the scale at 304 pounds. I was 55 years old. I had tried everything. Low carb. High protein. Meal replacements. Personal trainers. Nothing lasted.
Then I sat down with a calculator and figured out my actual numbers. My BMR. My daily baseline. The real math my body runs on. I set a goal: 175 pounds by November 22, 2017.
I hit 175 on November 17. Five days early. 129 pounds in 260 days. Not because I found some secret. Because I finally understood the equation - and I stopped quitting.
I posted my scale every single day. Publicly. I call it Extreme Accountability. When the math says you are on track, posting is easy. Even on the days the scale goes up. Because you know it owes you.

They Stopped Guessing. Look What Happened.
The math made it make sense for the first time. I stopped guessing and started knowing. When the scale went up 2 pounds, I did not panic because I knew my numbers were right. The scale owed me - and it paid.

I have tried every diet. Keto, Weight Watchers, Noom, intermittent fasting. They all worked for a while. This is the first time I understood WHY they worked - and why they stopped. The equation does not care about willpower. It just works.

Alan does not sugarcoat it. He does not tell you what to eat. He shows you the equation and lets you figure it out. That respect for my intelligence is what kept me going when every other program made me feel stupid.

This Is Not for Everyone
The Math Diet Premium works if you are willing to do three things: learn your numbers, track your food honestly, and show up every day for 30 days. It does not work if you want someone to hand you a meal plan, if you are looking for a magic pill, or if you are not ready to see the truth on your scale.
This IS for you if:
- You are tired of guessing and want to understand the actual math
- You are willing to track your food for 30 days
- You can handle direct, honest coaching (Alan does not sugarcoat)
- You want to become the expert on YOUR body
This is NOT for you if:
- You want someone to tell you exactly what to eat
- You are looking for a 7-day miracle
- You are not willing to step on a scale daily
- You want a coach who tells you what you want to hear
