If you’ve been struggling with weight loss in Toronto, trying different approaches, and still finding the weight comes back… you’re not alone.

This is one of the most common frustrations I hear from clients, especially high-performing people over the age of 40  who feel like they’re doing “everything right.”

You lose the weight.
You feel hopeful.
And then—slowly or quickly—it comes back.

It can feel like your body is working against you.

I know this struggle firsthand. Over 13 years ago, I experienced what felt like an invisible force pulling my weight back to a certain number, no matter what I did. I would lose weight, only to see it bounce back up. It was as if my body had an inner thermostat, keeping me stuck at the same place. 

Fortunately that is when I discovered a very different approach for weight loss based on intermittent fasting that broke through this metabolic barrier so my body would finally burn fat.  After that 20 lb  loss, having reached my target weight, I used specific  strategies to reset and lock in my new body setpoint so it stabilized and has been easy to maintain since that time.

So if you are experiencing this same issue feeling like your body just wants to stay at the same weight no matter what you do,  it isn’t just your imagination  it is based on biology and science.

And once you understand what’s actually happening inside your body, you can finally stop fighting it and start working with it.

Why Your Weight Keeps Rebounding and What Is the Body Setpoint?

The body setpoint theory explains why our weight seems to hover within a certain range over time. Think of it like the thermostat in your home. When you set a temperature, your heating and cooling systems adjust to keep it stable. Similarly, your brain,specifically the hypothalamus,regulates your weight by adjusting your metabolism, hunger hormones, and energy expenditure to maintain the same weight also known as homeostasis.

If your weight drops below your setpoint, your body interprets that as a threat and responds by:

  Increasing hunger through hormones like ghrelin (the hunger hormone) Slowing metabolism to conserve energy. 

 Triggering cravings to encourage eating and restore lost weight.

This is why weight loss can feel manageable in the beginning but harder and harder to sustain.  

Your body is trying to protect you, not sabotage you. 

• The body setpoint theory explains why maintaining weight loss is difficult, biological mechanisms resist weight change.
• Hormonal changes (like leptin and ghrelin fluctuations) drive hunger and metabolism shifts when weight is lost or gained.
• Adaptive thermogenesis slows metabolism after weight loss, making it harder to keep weight off.
  Genetics play a strong role in an individual’s setpoint, but lifestyle factors (diet, exercise, sleep, stress) can gradually shift it.
  

Why Dieting Alone Doesn’t Work Long-Term

Most traditional approaches to weight loss focus on one thing: eating less.

And while that can create short-term results, it often comes at a cost.

When calories drop too aggressively, especially without preserving muscle, your body adapts. It becomes more efficient, burns fewer calories, and increases hunger signals to restore what was lost.

This is known as adaptive thermogenesis, and it’s one of the key reasons weight regain is so common.

Research shows that more than 80% of people regain weight within a year of dieting. Not because they failed—but because their body was never guided through a process to reset its internal setpoint.

How to Reset Your Setpoint for Good

Sustainable weight loss and more importantly, maintenance requires a phased approach.

It starts with losing fat in a way that supports your metabolism, not works against it. This is where strategies like intermittent fasting, structured nutrition, and strength-based movement come into play helping you lose the right kind of weight while preserving muscle.

From there, the most important shift happens: the transition phase. Think of this as a transition to final long term maintenance lifestyle

Instead of suddenly changing from the fat burning phase to maintenance phase, your nutrition and lifestyle are adjusted gradually. Calories are increased strategically, your metabolism stabilizes, and hunger hormones begin to normalize. This gives your brain time to “accept” your new weight and reset the body setpoint just like resetting the thermostat in your home.

And once that happens, everything becomes easier.

Your body no longer fights you in the same way. Hunger feels more manageable. Cravings decrease. Your weight becomes far more stable.

This is why it is a crucial step in my weight loss programs. Once a client reaches their weight loss goal, we focus on a 4 week Locking In phase to transition from losing fat mode to maintenance mode. 

This allows time for the part of the brain, the hypothalamus, that is responsible for setting the body setpoint  to “catch up” with the “ new” body, and lock in this  lower weight as the new body setpoint. 

This is where clients often describe feeling a sense of freedom—not just physically, but mentally.

Your Body Wants Stability So Support This Process

If you’ve struggled with weight regain after a loss, it’s not because you lack willpower, it’s because your body is wired to protect its setpoint. The solution isn’t to fight your biology but to work with it by adopting sustainable habits that gradually reset your setpoint over time. If you want to lose weight and lock it in permanently, let’s chat. My program is designed to help you shift your setpoint, so you don’t have to keep starting over. Ready to break free from the cycle?
