Hi there!👋 My name is Guillermo
Owner and Head Nutrition Coach of GBG
I used to struggle with being insecure about how skinny I was when I was a kid but what really changed the game for me was the impact that a proper program had on my mom.
When I was in University and started to apply the things I was learning to myself, I saw the power that nutrition had.
Then I started making my mom apply all the things I was doing and I couldn't believe how happy it made her. As a single mom, she was starting to feel like herself again. She started getting an unmatched confidence in her body and strength. She said she was no longer surviving, she felt in control.
This was so powerful to me that it led me to create the GBG Method.
Most moms are struggling to balance family, work, and fitness — always putting themselves last.
I want to spare you the time & headache in my free 14-day GBG Challenge where I will personally help you achieve the same.
Why Diets Keep Failing You. Here's why:
Old Way
❌Start in an aggressive calorie deficit right away
❌Focus only on losing weight — not building muscle
❌Promote eating as little as possible
❌Rely on excessive cardio instead of strength training
❌No reverse dieting or exit strategy after fat loss
New Way
✅Build metabolism before entering a deficit
✅Prioritize muscle growth to drive fat loss
✅Increase calories strategically over time
✅Use structured phases (maintenance, build, cut)
✅Focus on long-term sustainability, not quick fixes

If you are looking for a nutritionist Guillermo is the one to go to he truly is amazing!My goal was to lose most of my fat around my belly and he was able to help me out with a meal plan that worked for me and was easy to follow and stick to, best of all I was eating more meals with snacks in between and wasn’t starving. I booked a 12 week plan with him and during that time I went from weighing 220 pounds to 189 pounds. Today I feel great and I’m proud that I was able to accomplish something for myself with his guidance. I highly recommend Gains by Guillermo 💯!

Guillermo and I have been working since 2021! We’ve had different goals in the past but this year was different I lost around 10lbs from a rough 1st and 2nd trimester of pregnancy. I went from 125lbs to 135lbs he helped put me on a plan make sure I was eating nutritional food with all changes in tastes and smells that come along with pregnancy, making sure I tracked my water intake, and energy levels that take a toll from all the physical changes. My doctor took a huge a notice from my December app. to January app. She was very impressed with the work Guillermo and I have been doing to get me on the proper weight gain for me and baby. If wasn’t for his help in the last few years it wouldn’t have been this easy to get back on track with a specific meal plan and having him to answer any questions.
