Fat loss comes down to eating fewer calories than you burn for long enough to matter. Everything else — meal timing, food choices, training splits, supplements — either helps you hold that deficit or it does not.
The reason most attempts fail is not that the plan was wrong. It is that the deficit was too aggressive to sustain, so it collapsed after three weeks and took the progress with it. The goal is the largest deficit you can hold without your energy, training, or mood falling apart.
A deficit of 15–20% below maintenance suits most people. If maintenance is 2,400 calories, that is roughly 1,900–2,050 per day, and about 0.5–1% of body weight lost per week.
Faster is not better. Very large deficits cost you muscle, training quality, and sleep, and the weight returns because the diet was never liveable. If you have a lot of weight to lose you can hold the upper end comfortably; if you are already lean, stay near the lower end and expect slower progress.
Pick the number, then hold it for at least three weeks before judging it. Two weeks is not enough data to separate real change from water weight.
Protein and lifting decide what you lose
A calorie deficit causes weight loss. Protein and resistance training decide how much of that weight is fat rather than muscle.
Aim for roughly 1.6–2.2 g of protein per kg of body weight (about 0.7–1.0 g per pound). If you carry significant excess weight, base it on a target weight instead so the number stays sensible.
Lift two to four times a week and try to keep your working loads roughly where they were. Strength holding steady in a deficit is a good sign you are keeping muscle. Strength falling off quickly usually means the deficit is too steep, protein is too low, or sleep is too short.
Track the trend, not the day
Daily weight moves with salt, carbohydrate, hydration, menstrual cycle, and the timing of your last meal. Any single reading is close to meaningless.
Weigh yourself under the same conditions most mornings and compare weekly averages. A week averaging 82.1 kg following a week averaging 82.5 kg is real progress, even if one morning read 83.0.
Add one measurement the scale cannot fake: waist circumference at the navel, or how a specific pair of jeans fits. When the scale stalls but your waist keeps shrinking, you are recomposing, and stopping there would be a mistake.
What to do when progress stops
Genuine plateaus are usually adherence drift rather than a broken metabolism. Portions creep, weekends loosen, and daily movement falls as energy drops.
Before cutting calories again, log everything honestly for one week — including cooking oil, drinks, and bites while cooking. Most stalls resolve themselves here.
If intake is genuinely on target and the four-week average has not moved, reduce by around 100–150 calories per day or add movement, not both at once. Change one variable so you can tell what worked.
Plan the breaks before you need them
Long diets work better with planned pauses. After 8–12 weeks in a deficit, spending one to two weeks at maintenance calories gives you a psychological reset and often improves training quality.
You will usually gain a little scale weight during a break. Most of it is food volume and glycogen, not fat, and it disappears within days of resuming.
Deciding your break schedule in advance also stops an unplanned bad week from feeling like failure. It was always part of the plan.
Common questions
How fast should I lose weight?
About 0.5–1% of body weight per week suits most people. Heavier individuals can sustain the upper end; leaner individuals should aim lower to protect muscle.
Why did I stop losing weight in a calorie deficit?
Most stalls come from unlogged intake creeping upward and daily movement dropping, not from a damaged metabolism. Log everything for a week before reducing calories further.
Do I need cardio to lose fat?
No. Cardio adds calorie burn and benefits your heart, but the deficit drives fat loss. Resistance training matters more for keeping muscle while you lose.
