How to Start Your Weight Loss Journey: A Practical Guide (Part 1)

The Foundation: Energy Balance

So you've decided its time to shed a few kilos! Weight loss comes down to one principle: consuming fewer calories than you burn. While there are some exceptions to the rule (e.g. hypothyroidism), there is fundamentally no if's or but's about the calorie seesaw. Your body needs energy to function, and when you provide less than it needs, it turns to stored fat to make up the difference.

Your total daily energy expenditure has four components:

• Basal metabolic rate (60–70%) — what you burn simply existing and staying alive.
• Physical activity (15–30%) — exercise and movement
• NEAT (non-exercise activity thermogenesis) — fidgeting, walking, standing
• Thermic effect of food (~10%) — energy used digesting what you eat

A deficit of roughly 500 calories per day typically produces about 0.5 kg (1 lb) of loss per week. Aggressive deficits work faster but are harder to sustain and cost you more muscle. I strongly recommend a happy medium. If you are a pedal-to-the-metal sort of person a hardcore all-or-nothing approach can work. However, the rest of us crash and burn. Consistency is the goal for weight loss.

Practical first step: Before you can calculate how many calories you need to lose weight, you need to know what you are eating. Track everything you eat for one week without changing anything. Most people underestimate their intake by 20–30%. You can't adjust what you haven't measured.

Nutrition Myths Worth Discarding

"Carbs make you fat." Carbohydrates don't uniquely cause fat gain — excess calories do. Low-carb diets often work well because protein and fat are satiating and cutting carbs removes many calorie-dense processed foods.

"Eating late causes weight gain." Meal timing matters far less than total intake. Late eating correlates with weight gain mainly because evening snacking tends to be mindless and calorie-heavy.

"You must eat six small meals to stoke metabolism." The thermic effect of food scales with how much you eat, not how often. Three meals or six — pick what controls your hunger.

"Detoxes and cleanses reset your system." Your liver and kidneys handle this. Juice cleanses mostly cost you water weight and muscle.

"Fat-free means healthy." Removing fat usually means adding sugar and stripping out satiety.

What's Actually Supported

• Protein is your highest-leverage change. Aim for 1.6–2.2g per kg of bodyweight. It preserves muscle in a deficit, has the highest thermic effect, and keeps you full.
• Fibre matters enormously. 25–35g daily from vegetables, legumes, and whole grains slows digestion and improves satiety.
• Resistance training preserves muscle. Without it, up to 25% of weight lost can be lean tissue, which lowers your metabolic rate.
• Sleep affects appetite hormones. Under 7 hours raises ghrelin and lowers leptin — you'll be hungrier and less satisfied.

The Leading Approaches Right Now

Mediterranean diet — Consistently ranked the best overall. Vegetables, olive oil, fish, legumes, and whole grains, with strong evidence for cardiovascular health and long-term adherence. Not a rapid-loss protocol, but sustainable.

High-protein, moderate-carb — Straightforward calorie control with excellent satiety and muscle retention. Works especially well alongside strength training.

Time-restricted eating (16:8) — Confining eating to an 8-hour window. Research suggests results roughly match continuous calorie restriction; it works because it naturally limits intake, not through metabolic magic. Suits people who prefer rules over tracking.

Low-carb and keto — Fast early results (largely water weight) and strong appetite suppression. Effective for some, socially restrictive for many. Long-term outcomes converge with other approaches once calories are matched.

Volume eating — Prioritising low-calorie, high-volume foods (vegetables, broths, lean protein) so you eat large portions within a deficit. Less a diet than a tactic that supports any approach.

GLP-1 medications — Semaglutide and tirzepatide have changed the landscape for clinical obesity. They're prescription tools requiring medical supervision, not a substitute for the nutritional habits that determine what happens after you stop.

Starting This Week

- Track intake for seven days without judgement. Its important to be truthful with yourself.

- Set a modest deficit- 300–500 calories below maintenance (find out how many calories you need here)

- Hit your protein target daily.

- Begin any sort training twice weekly (weights, walking, riding, swimming). Dont go too hard, lets establish some good habits, routine and have some fun.

- Weigh yourself daily but only track the weekly average — daily fluctuation is water, not fat

The best diet is the one you'll still be following in six months. Choose an approach that fits your life rather than one you'll have to endure.
