It's not your fault. These four things derail almost everyone who tries to lose weight without proper coaching behind them.
01
Unsustainable Diets
Extreme calorie cutting works short-term then backfires. You lose weight, stop the diet, gain it all back — often more.
02
No Structured Plan
Random gym sessions or YouTube workouts don't build the habits that lead to lasting change. Structure is everything.
03
No Accountability
When no one is checking in, one bad week becomes two, then three. Accountability is what keeps you consistent.
04
Conflicting Advice
The internet is full of noise. Without a coach cutting through it, most people waste months on things that don't work.
At DJB Fitness, weight loss isn't about starving yourself or punishing yourself in the gym. It's about building a plan that works for your lifestyle and delivers consistent, long-term results.
A clear, personalised training plan built from scratch around your goals
Simple nutrition guidance that fits your actual life — not a celebrity diet
Ongoing support and accountability every step of the way
A proven system focused on sustainable fat loss that lasts
At DJB Fitness, weight loss isn’t about starving yourself or doing endless cardio. It’s about building a plan that works for your lifestyle and delivers consistent, long-term results.

You don't need to spend hours in the gym every day. Each session is planned and purposeful. Everything has a reason, and nothing is wasted.
Training is built around your schedule, your fitness level, and your goals. Whether you're a complete beginner or have trained before, every session is designed for where you are right now.
No cutting out food groups. No counting every calorie. Just clear, realistic guidance that works alongside your actual daily life, because a plan you can't stick to is no plan at all.
David's nutrition approach is built around sustainability. The goal is to help you eat well consistently, not perfectly for two weeks and then not at all.

Most clients start noticing changes within the first few weeks. Consistent training and nutrition lead to steady, sustainable fat loss over time.
No. The focus is on simple, sustainable nutrition that fits your lifestyle, not extreme or restrictive dieting.
This depends on your current fitness level and goals, but most clients see strong results training 2 to 4 times per week alongside proper nutrition.
Not necessarily. A combination of strength training, movement, and nutrition is far more effective than relying on cardio alone.
Everything is tailored to you. No generic plans, just structured coaching, accountability, and a clear approach designed to get real results.
Based in Crieff, DJB Fitness provides weight loss coaching and personal training for clients across Perth, Kinross and surrounding areas.
When you search for a personal trainer to help you lose weight, you need more than a generic workout plan.
You need a coach who simplifies the process and keeps you accountable through the hard weeks.
