How to Lose Weight in Ireland: The Whole Method, Free

What I actually paid a trainer for

I started training in February 2023, six months before my wedding. I was over 90kg and had no real idea what I was doing, so I hired a personal trainer and paid him thousands. What I got for that money was three things: a calorie deficit, enough protein, and someone keeping me consistent.

That is not a complaint. He did the job and I got the result. But those three things are simple enough to explain over a coffee, and that is what the rest of this page does. The guides, the calculators and the plans on this site are free for that reason.

Step 1: find your number

Everything starts with a calorie target. Not a perfect one, a starting one.

• Work out your maintenance. The TDEE calculator estimates what you burn in a normal day. A deficit of 300 to 500 under that is a sensible place to start. Treat the result as a first guess you will adjust, not a prescription.
• Split it into protein, carbs and fat if you want the detail. The macro calculator does that for you.
• Log for a few weeks, not forever. How to count calories covers what to weigh, what to estimate and why two to four weeks of logging is enough to calibrate your eye.

Most stalled diets are not really stalled. They are a few hundred calories a day heavier than the person thinks, and almost none of it comes from meals. It is the oil in the pan, the milk, the drinks and the mouthfuls that never get logged. Hidden calories shows where it usually goes.

Step 2: get enough protein

Protein keeps you full and helps you hold onto muscle while you lose weight. About 1.6g per kilo of bodyweight a day is a practical starting point for many healthy adults who train. For an 80kg person that is roughly 130g. How much protein per day explains the range and when it changes.

Here is the part most people miss: grams of protein per 100g tells you very little on a diet. What matters is how many calories come with the protein. That is why I built the Protein Swap Lab, which compares foods by protein per 100 calories using real labels, and the protein ranking for Irish supermarkets, which does the same for Tesco, Aldi, Lidl and SuperValu staples.

Step 3: food you will actually eat

Use meals you recognise and can make on a normal Tuesday. Eggs on toast. Greek yoghurt, oats and frozen berries. Chicken, microwave rice and a bag of veg. Repeating a breakfast or lunch, planning the Aldi, Lidl or Tesco shop, and weighing the foods that are easy to overpour leaves fewer surprises.

• Short on time? Meal prep for beginners covers batch cooking, cooking on the day and ready meals.
• Want the week planned for you? The 7-day meal plan uses real food from Aldi, Lidl, Tesco or Dunnes, with macros worked out from the labels.
• Checking a specific food? Calories in Ireland searches Irish supermarket products, and FoodSussed helps you compare the label.
• Wondering how processed it is? How processed is your food? explains Levels 1 to 4 with real protein products sold in Ireland.

Labels still need a bit of suspicion. Flavours in the same range can have quite different labels, so one attractive calorie number cannot be copied across the range.

Step 4: train and keep moving

You can lose weight without the gym. But if you want the weight that comes off to be fat rather than muscle, lifting helps, and it is what changes how you look at the end.²

• New to lifting? Start with how to build muscle, then progressive overload, which is the one idea that makes training keep working.
• Not sure how many days? The training split recommender picks a split that fits your week. If you have five days, there is a free 5-day gym split.
• For women worried about bulking up: weight training for women covers what actually changes.
• Walking counts. The Everyday Movement planner helps you find where more walking could fit into your week.

Step 5: watch the week, not the morning

Weight moves with water, food volume and salt as much as fat. One high weigh-in means nothing. The weekly average means a lot. Weighing yourself regularly helps when it is part of a wider plan, not as a trick on its own.¹

When the tracker launches, you can record your food and weight and look at the trend line. If three weeks go by with no change, why am I not losing weight? walks through the checks in the right order before you cut anything. For a simple weekly review of your first month, use the first-month review table.

What quietly stalls it

• Sleep. Sleep does not burn fat, but short nights make the deficit harder to hold and make you hungrier the next day. Sleep and fat loss has the detail.
• Drink. Alcohol does not stop fat loss. It costs a lot of calories and makes everything around it harder. Six pints is roughly 1,200 calories before the takeaway. Alcohol and fat loss has the honest version, and weekends and eating out covers the rest of the weekend.
• The small stuff. Oil, milk, sauces and picking. See hidden calories.
• Hunger. Starving by 3pm is usually a meal problem, not a willpower one. Hungry between meals? shows how to fix the meal before it.

Reached your goal weight? After fat loss covers moving to maintenance or a lean bulk without losing the habits that got you there.

Pick your situation

• Mostly around the middle? You cannot choose where fat comes off first. How to lose belly fat explains what does work.
• A lot to lose? How to lose 20kg covers what each stage feels like so you do not quit in the boring middle.
• Not heavy, just soft? That is usually skinny fat, and it needs more muscle as much as less fat.
• Lost the weight and want to build now? The muscle-building guide and the free Year Two guide are for that stage.

How long it takes

With a deficit of 300 to 500 a day, around half a kilo a week is a realistic pace for most people. That means losing 20kg usually takes nine months to a year. There is no honest version that takes six weeks. My own 18 kilos took far longer than I expected, and it only stuck once I stopped trying to rush it.

What the Irish numbers do and do not tell us

The Ireland fitness statistics page keeps the national figures in one place. The short version is that a national average cannot set your meals or your training. It only gives context. The practical question is still what can be repeated this week. There is more detail in How Active Is Ireland?.

When to use HSE or GP support

A general website is not enough when weight changes need medical assessment, prescription treatment is involved, or food and weight are tied up with medication, pregnancy, breastfeeding, a health condition or disordered eating. The HSE describes a free 12-month programme run by its dietitians. That or a GP is the proper route.³

Questions people ask me

How many calories should I eat to lose weight?

Start around 300 to 500 under your maintenance calories. The TDEE calculator estimates maintenance, but it is a guess, so adjust after three weeks of real weigh-ins.

How fast can I lose weight?

For most people, around half a kilo a week is a realistic pace with a modest deficit. Faster weeks happen early, mostly from water. Judge the trend over several weeks.

Do I have to count calories forever?

No. Two to four weeks of logging teaches you what your normal portions actually are. After that, most people can estimate well and check in when the trend stalls.

Can I lose fat from just my belly?

No. You cannot choose where fat comes off. A steady deficit, protein and resistance training reduce your waist over time, along with everywhere else.

Do I need supplements or fat burners?

No. None of it is necessary. A calorie target, enough protein from food, training and patience do the work. If you use protein powder, treat it as convenience food, not a requirement.
