The program

Major weight loss isn't one phase. Your plan shouldn't be either.

Losing a significant amount of weight can take time. Your calories, training, recovery, mindset and goals won't stay the same from beginning to end — so we adjust the plan as you change.

01
RD-led · monthly

Create a calorie deficit you can actually sustain

Major weight loss requires consistency over months, not extreme restriction for weeks. Your nutrition strategy is personalized around your starting point, food preferences and lifestyle, then adjusted as your body and needs change.

02
Coach · weekly

Protect muscle while you lose weight

The goal isn't simply to become smaller. Progressive resistance training and adequate protein help prioritize muscle preservation while you lose body fat — supporting strength, function and better body composition.

03
Coach + RD support

Navigate plateaus without starting over

Weight loss rarely happens in a perfectly straight line. Your team reviews trends, adherence, nutrition, activity and progress before deciding what actually needs to change — rather than reacting to every frustrating week.

04
RSW + CC · monthly

Change the patterns underneath the weight

Major weight loss can involve much more than calories. Emotional eating, all-or-nothing thinking, stress, self-sabotage and years of dieting can all influence the journey. Registered professionals help you build behaviours that can last beyond the diet.

05
Whole-team support

Adapt as your body changes

A plan that worked 50 pounds ago may not be the plan you need today. Training, nutrition, movement, recovery and goals evolve throughout significant weight loss — and your program evolves with them.

06
Maintenance-focused

Learn how to keep the weight off

Maintenance isn't what happens after the program. It's a phase we prepare for. Calories increase strategically, training continues and your focus shifts from losing weight to maintaining your new body without returning to old extremes.

GFIT coach Sarah Knight
Major Weight Loss & Long-Term Maintenance

Sarah Knight

Sarah doesn't coach major weight loss from theory — she's lived it. She lost 100 pounds and has kept it off for 14 years, and navigating the transition from active loss into lasting maintenance shapes an approach built on sustainable habits, not temporary restriction. She also supports clients on GLP-1-assisted weight loss.

"I lost 100 pounds and kept it off for 14 years, so I know lasting change comes from habits you can actually sustain — not quick fixes."

★★★★★

"I hit 9.6 lbs lost and 10 inches! Completed 5 weeks of 5am workouts, no excuses made yet!"

Major Weight Loss, GLP-1 Support & Relationship With Food

Amanda Chartrand

Amanda has personally lost 100 pounds and maintained it for over a decade. A Certified Personal Trainer and Nutritionist with GLP-1 weight-loss support training, she focuses on sustainable fat loss, healing the relationship with food and moving away from the yo-yo dieting cycle.

"I spent years stuck in yo-yo dieting before I lost 100 pounds and kept it off for over a decade. What changed everything was healing my relationship with food — not another quick fix."

★★★★★

"I'm proud of staying 100% this week — and, honestly, feeling good in my body."

FAQ

Major weight loss & maintenance common questions

How do I lose 100 pounds safely?
Losing 100 pounds is a long-term goal rather than a short diet. Your appropriate rate of weight loss depends on your starting point, health, nutrition and individual circumstances. GFIT builds a personalized calorie, nutrition, strength-training and behaviour strategy and adjusts it throughout the journey. Medical concerns should be managed with your physician or appropriate healthcare provider.
How long does it take to lose 50 or 100 pounds?
There is no responsible universal timeline. Weight loss is rarely linear, and the appropriate rate varies between individuals. Larger goals typically require multiple phases rather than one continuous aggressive calorie deficit. GFIT focuses on steady progress, muscle preservation and a strategy you can sustain rather than promising a deadline.
How do I preserve muscle while losing a significant amount of weight?
Progressive resistance training, adequate protein and an appropriately managed calorie deficit are important parts of preserving lean mass during weight loss. Your GFIT coach programs strength training while Registered Dietitians help individualize your nutrition and protein strategy.
Why does weight loss slow down after I've already lost a lot?
As body weight decreases, energy requirements can change and the calorie deficit that produced earlier progress may become smaller. Activity, adherence, hunger, recovery and other factors can change too. Rather than assuming you've "failed," your team reviews the trend and determines whether nutrition, movement, training or another part of the plan needs adjusting.
How do I avoid regaining weight after a major weight loss?
There is no way to guarantee that weight will never return, but maintenance can be actively planned. GFIT transitions clients from active weight loss into a dedicated maintenance phase where nutrition, training, monitoring and behaviour strategies are adjusted around maintaining the new weight rather than continuing to diet indefinitely.
Can GFIT help if I've lost and regained weight several times?
Yes. Repeated cycles of dieting and regain are common among people seeking significant weight loss. Rather than simply prescribing another aggressive diet, GFIT looks at what made previous approaches difficult to sustain and builds nutrition, training, behaviour and maintenance strategies around the longer-term problem.
Can I do this program while taking Ozempic, Wegovy or Mounjaro?
Yes, when the medication is prescribed and managed by your healthcare provider. GFIT does not prescribe or adjust GLP-1 medications. Your coaching focuses on nutrition, protein, strength training, muscle preservation, behaviour change and building habits that support your overall weight-management plan.
Can GFIT support me before or after bariatric surgery?
GFIT can provide complementary fitness, nutrition, lifestyle and behaviour coaching, but your bariatric medical team remains responsible for surgical care, clinical nutrition requirements and medical follow-up. Any GFIT plan should align with the instructions provided by your bariatric healthcare team.
Will I have loose skin after losing a lot of weight?
Loose skin can occur after significant weight loss, but the amount varies considerably based on factors such as total weight lost, age, genetics, skin elasticity and how long the higher weight was carried. Strength training can help build muscle underneath the skin and improve body composition, but exercise cannot guarantee that loose skin will be prevented or removed.
Is major weight-loss coaching covered by insurance in Manitoba?
The fitness-coaching component itself may not be reimbursed as standalone personal training, but eligible 1:1 sessions with GFIT's Registered Dietitians, Registered Social Workers, Occupational Therapists, Psychologists, Naturopathic Doctors and Clinical Counsellors may qualify under extended health benefits. GFIT also works with NIHB, VAC and CAF. We'll review your specific coverage during your free discovery call.
