183 cm · 100 kg · 43 · gluten-free · no breakfast
A gluten-free meal-prep week, weighed to the gram, built to lose fat while you train for muscle. Meat, fish and skyr are bought as whole packs and used up over consecutive days. Nothing before lunch. Each day lands on the calorie level you pick and about 190 g of protein.
How the numbers were set, how to adjust them, and where gluten hides.
| Figure | Value | Where it comes from |
|---|---|---|
| Resting burn | 1,934 kcal | Mifflin-St Jeor equation for 100 kg, 183 cm, 43 years, male |
| Maintenance | ≈ 2,800 kcal | Resting burn × 1.45 for three to five home sessions a week and a normal day otherwise |
| Target | 2,300 kcal | A 500 kcal daily deficit, about 0.5 kg of fat a week |
| Protein | ≈ 190–200 g | 1.9–2.0 g per kg of body weight; it moves a little with the size of the packs you buy |
| Fat | 48–76 g | Enough for hormones and absorption, low enough to leave room for carbs |
| Carbs | 205–245 g | Whatever calories are left; this is the part the level switch changes |
| Fibre | 31–47 g | Vegetables, pulses, oats and fruit; it is what keeps a big eater full |
The maintenance figure is an estimate, and it can be off by 10% or more for any one person. Your scale over the first three weeks is the real measurement. Treat 2,300 as the opening bid.
On protein: a meta-analysis of 49 trials found that muscle gain from lifting stops improving at around 1.6 g/kg a day, with the uncertainty reaching up to 2.2 g/kg. Those trials were not run in a deficit. When you are eating below maintenance the body is quicker to break muscle down, so the plan sits near the top of that range. High protein also keeps you fuller than the same calories from carbs or fat.
You cannot buy 230 g of tenderloin, so the plan never asks for it. Each meat or fish is one whole pack, split over two or three days in a row, as two different dishes or as one pot eaten twice.
| Pack | Days | What it becomes |
|---|---|---|
| Chicken breast, 750 g | Mon–Wed lunch | Roasted whole on Monday, then a rice bowl, then a lentil curry |
| Beef mince, 500 g | Mon–Tue dinner | One pot of chilli, with rice the first night and baked potatoes the second |
| Salmon, 2 fillets | Thu–Fri lunch | Rice bowl, then traybake |
| Turkey mince, 500 g | Thu–Fri dinner | Burgers, then bolognese |
| Pork tenderloin, whole | Sat–Sun lunch | Roasted with sauerkraut, then fried rice |
| Turkey breast, 500 g | Sat–Sun dinner | With buckwheat and mushrooms, then a pepper goulash |
Weigh yourself every morning after the toilet and before eating, and compare weekly averages, never single days. Measure your waist at the navel once a week as a second signal.
Every food in this plan is naturally free of gluten. The risk is in what gets added during processing. These are the labels to read:
In the EU, "gluten-free" on a label means under 20 mg of gluten per kg, and cereals containing gluten must be highlighted in the ingredients list.
Food decides whether you lose weight. Training decides whether that weight is fat or muscle. Three or four sessions a week that work every major muscle, taken close to failure, with reps or load going up over time, is what makes the protein count.
The bands are a good buy. Looped over the pull-up bar they take some of your weight, so you can do full pull-ups for more reps at 100 kg, and they add rows, face pulls and resisted push-ups that dumbbells do not cover well.
This plan assumes healthy kidneys and no medication that affects diet. If either is in question, show the numbers to your doctor first.
