Why We Donโ€™t Count Calories: The Hormone Truth of Fat Loss

bangkok fat loss group classes gyms in bangkok hormones personal training sathorn Feb 19, 2026

 

The 30-Second Summary:

The Myth: The fitness industry has been trapped in the "calories in, calories out" model for decades.

The Reality: Hormones dictate everything. They determine if your body stores fat or burns it, how hungry you are, and your metabolic rate.

โšก๏ธ The Flash Fitness Habits and Hormones Method: At Flash Fitness in Sathorn, we don't focus on counting calories. We focus on training and nutrition protocols that optimize metabolic hormones (Insulin, GLP-1, Cortisol, Testosterone) for sustainable fat loss.

 

The fitness world... the weight loss world has been trapped for decades.

Trapped using the "calories in and calories out" method.

At Flash Fitness in Sathorn Bangkok, Ritah and I do not use calorie counting or macro counting. In 2015, we wrote a book giving the basics as to why. (The Habits and Hormones Solution). 

We choose to find and do the habits that shift hormones involved in metabolic regulation.

Why? Because hormones dictate everything.

They dictate how your body USES food. Whether your body burns and stores glucose and fat. How hungry you are. How much your metabolic rate declines.

Look... if you are still stuck on calories being more important than hormones... consider the real world:

โœ”๏ธ Ozempic (GLP-1): It is a GLP-1 agonist. A hormone. People have struggled losing weight for years using Weight Watchers, dieticians, nutritionists, and more calorie-burning cardio. Fail after fail. Then they inject ONE hormone. Boom. They lose the weight. Not calories. Hormones.

โœ”๏ธ Testosterone Therapy: Men get a little older, start gaining fat and losing muscle. So, they go and take testosterone therapy... yup, injecting ONE hormone. Boom. Lose fat and gain muscle.

โœ”๏ธ Insulin: Diabetics start taking insulin injections... BOOM. Fat gain.

โœ”๏ธ Menopause: Hormones change overnight. Fat gain. Studies show up to 10kg on average. Not a change in calories. Hormones.

Cue the trainer who cannot stand to hear that the methods he was taught and  learned at his certification, where he memorized names of bones and muscles and passed his multiple choice test…

๐Ÿ—ฃ๏ธ “Oh, but Jeff. The hormones changed their calories in and calories out.”

Okay. So, thank you.

You just proved me right.

Calories are the end measurement. Calories are nothing more than a simple measurement of heat after the fact.

Calories are NOT the methodology. They are the side effect.

A measurement doesn’t help REGULATE metabolism until after the fact.

You don’t build cars around MPH.

You build a car properly, and how many miles per hour it can do is after the fact.

If you want to lose fat fast and in a sustainable way... you train for metabolic health with hormones in mind.

Insulin. Cortisol. Catecholamines. Growth hormone. Testosterone, GLP-1... etc.

All of these can be controlled through understanding HOW to do nutrition and exercise a certain way. All can be summoned if you understand the physiology.

This is why we succeed with so many clients at Flash Fitness. That is our real secret. We choose NOT to focus on calories like the rest of the fitness industry.
