Results

I've done it myself, and with clients like these

Before and after photos of Paris Demers, who gained nearly 30 lb while traveling and then lost it and kept it off

Me · lost nearly 30 lb

Gained nearly 30 lb traveling for a year, then lost it. I know the stalled weeks, the hunger and the doubt.

Kept off for 2 years

Before and after photos of Bini, who lost 20 lb and doubled his deadlift in 8 months of personal training in Vancouver

Bini · −20 lb in 8 months

Plan built around his injuries, with planned fat loss phases. Deadlift 150 to 300+ lb.

Still getting leaner

+65 lb on his squat, and a 5K two minutes faster.

Kept it off over a year

Why it fails

Three reasons the weight comes back

It isn't a lack of discipline. Most plans don't deal with any of these.

71%regained, fast or slow[2]

The plan ends when the diet ends

No maintenance phase, and hunger rises as you lose.[3] Without a plan for after, it comes back.

5%muscle lost, cardio only (2% lifting)[4]

Muscle goes with the fat

Eat less and your body burns muscle too, unless you lift and eat enough protein.[5]

0.35%normal weekly swing[6]

Nobody tracks, so nothing changes

Without numbers you can't tell a real stall from noise, so people quit or change the wrong thing. Tracking helps.[7]

71%: share regained at about 3 years among people who first lost 12.5%. 5%: dieting older adults. The fixes below are my coaching view, not study findings.

My method

Here's how I fix all three

  1. 01

    Assess

    Strength, mobility, movement, diet, sleep and lifestyle. You get your starting numbers.

    YOUR STARTING POINT
  2. 02

    Plan

    A custom diet strategy, progressive strength training and a step target, built around your schedule and injuries.

    FIXES: MUSCLE LOSS
  3. 03

    Train

    In person or online, adding small habit changes over time, so results don't depend on willpower.

    BUILDS HABITS THAT LAST
  4. 04

    Weekly check-in

    Weight trend, training, steps and food. If it stalls, I change one thing. Re-test every 6 to 8 weeks.

    FIXES: NOBODY TRACKS

Steps 3 and 4 repeat weekly

At your goal we move to a planned maintenance phase, so the weight stays off.

FIXES: NO PLAN FOR AFTER

Step 1 starts here. No pressure, no contract.

On Ozempic, Wegovy, Mounjaro or Zepbound?

Training matters even more on a GLP-1. People regained about 0.4 to 0.8 kg a month after stopping.[8] Strength training, protein and tracking protect your muscle now and your results later.

Is this for you?

YES, IF YOU
  • Want to lose fat and keep it off
  • Will track a few numbers each week
  • Want to understand the plan, not follow it blindly
NOT IF YOU
  • Want a crash diet or a quick fix
  • Want someone to promise a number by a date

No guarantees. No "lose 20 lb in 6 weeks." I'll give you a realistic pace after your baseline.

Common questions

Fat loss questions, answered

How much does it cost?

Studio and in-home training start at $600 CAD a month plus GST, depending on how often we train. Online pricing is on the online coaching page. It's month-to-month.

How fast will I lose fat?

It depends on where you start. A common starting point is 0.5 to 1% of bodyweight a week, which helps keep muscle, though that guidance was written for lean athletes.[9] I'll give you a realistic pace after your baseline.

Can I lose 20 pounds in 2 months?

Some people lose that fast, but speed isn't the goal. In one trial, people who lost weight quickly and people who lost it slowly regained the same share.[2] I'll set a realistic pace after your baseline.

Do I need to follow a strict diet?

No. I build a custom diet strategy around your food, schedule and preferences, so it's something you can live with.

I've lost weight before and gained it back. Why would this be different?

On average, people regain more than half of the weight they lose within about two years.[1] This plan builds in what most skip: weekly check-ins to track real progress, strength training to protect muscle, and a planned maintenance phase.

I'm on Ozempic, Wegovy or Mounjaro. Can you still help?

Yes. I work alongside whatever your doctor prescribes and focus on strength training, protein, tracking and habits. I don't advise on medication.

What happens at the weekly check-in?

We review your weight trend, training, steps and food. If your progress stalls, I change one thing, not everything, so we know what worked.

Studio, in-home or online?

Studio gives me the most hands-on coaching. In-home saves you the trip. Online works if you're comfortable training on your own with weekly check-ins. In person, I train clients in downtown Vancouver, Coal Harbour, the West End and the Stadium District.
