Why You Can't Lose Weight: 5 Mistakes Keeping You Stuck

When I sit down with a new client and ask about their history with weight loss, I hear some version of this story almost every time:

"I feel completely lost and out of control. One day I eat too little, the next I eat too much. I tried to stick to 1,000 calories — by day four I was starving, moody, and couldn't focus or sleep. One cheat meal turned into two full days of overeating. The guilt hit hard, and by Monday morning I was in a state of despair, wondering why I can't just stick to a plan. I feel like I've tried everything."

Sound familiar?

Here's the truth: you can't white-knuckle your way through an extreme, unsustainable plan, and you can't set unrealistic goals and expect different results. That cycle — restrict, binge, guilt, repeat — isn't a willpower problem. It's a strategy problem.

Deep down, most people know something isn't working. What's harder to see is why, and what to do instead. That's exactly where coaching changes everything. It removes the guesswork, keeps you accountable, provides a clear and realistic plan, and gives you a framework for handling the setbacks that will inevitably come. Without that structure, most people continue going in circles — not because they lack discipline, but because they're working without the right support.

The single biggest thing holding most people back isn't knowledge. It's making the decision to invest in themselves and get help.

5 Common Mistakes Keeping You From Losing Weight

1. Your calories are too low

If you're a woman eating 1,200 calories or less, or a man eating 2,000 calories or less for an extended period, your body will eventually fight back. Sadly, this is so common. Chronic under-eating — typically anything sustained for six months or more — triggers a process called metabolic adaptation. Your resting metabolic rate drops, thyroid hormones downregulate, and your body prioritises survival over fat loss. The result? You stop losing weight, or you start gaining it back, despite eating very little. Eating less is not always the answer — eating smarter is.

2. Chasing macros without caring about food quality

Hitting your protein and calorie targets matters — but so does what those calories are made of. Whole foods provide micronutrients, fibre, and phytonutrients that processed foods don't. These influence everything from hunger hormones and gut health to energy levels and recovery. You can technically hit your macros with protein bars and packaged food, and still feel flat, inflamed, and chronically hungry. Macros are a framework, not a free pass to ignore food quality.

3. Prioritising supplements over your diet

Protein powder, BCAAs, creatine, pre-workout, multivitamins — none of these will compensate for a diet built on processed food, or a weekend pattern of binge eating and heavy drinking. Supplements are called supplements for a reason: they work on top of a solid nutritional foundation, not instead of one. Spending $100 a month on supps while neglecting the basics is one of the most common and expensive mistakes I see.

4. Not eating enough throughout the day

Skipping meals or eating too little during the day doesn't save you calories — it sets you up to overconsume at night. By the time dinner comes around, you're running on stress hormones and willpower, and ultra-processed food becomes almost impossible to resist. Appetite hormones like ghrelin spike, satiety hormones like leptin drop, and decision-making becomes impaired. Distributing your food intake across the day is one of the most underrated tools for managing hunger and staying consistent.

5. Relying on sugar-free and low-calorie "diet" foods

Sugar-free jelly, protein bars, low-calorie ice cream, sugar-free biscuits — these are often marketed as the "healthy" choice, but many of them make it harder, not easier, to lose weight. They're typically low in nutrients, high in sugar alcohols and artificial sweeteners, and processed in ways that keep hunger elevated rather than reducing it. Some research also suggests that frequently consuming intensely sweet foods — even without the calories — can sustain cravings for sweet tastes over time. Real, minimally processed food fills you up more efficiently, and your body handles it far better.

Where to start

If you recognise yourself in any of these, you're not failing — you've just been given the wrong tools. The path forward isn't more restriction or more willpower. It's a structured, evidence-based approach that actually works with your physiology rather than against it.

That's what body recomposition coaching is designed to do.
