Six months on Saxenda and the weight has stopped moving
A plateau around six months is the most ordinary thing that happens on Saxenda, not a failure of the medication or of you. Weight loss curves in the trials flatten in the second half of the first year, because a smaller body needs less energy, because intake usually creeps up as side effects settle, and because lost muscle lowers what you burn at rest. The useful question at six months is not how to force the scale down again. It is what your waist, your strength test and your protein average have done over the last month.
Your number, before anything else
Protein is what decides whether the weight you lose is fat or muscle. Work your number out once and we will keep it with you on every page here. No account, no email.

Why six months is where the curve bends
Three things arrive together. You are carrying less weight, so everything you do costs less energy than it did in month one. Side effects have usually settled, so you are eating more than you were at the start without deciding to. And if protein has been under the floor, some of what you lost was muscle, which lowers resting energy use further. Pooled across 20 randomised trials, 26.8% of the weight lost on liraglutide was lean mass, against 26.2% when the same weight came off by diet alone, and 17.5% when resistance training was added.
The trials show the same shape. Weight comes off quickly for the first six months, then the curve flattens towards a plateau in the second half of the year. Liraglutide's appetite effect is milder and steadier than the weekly medications. Most people we coach on Saxenda can eat a normal small meal; the risk is subtler, because the appetite that remains is often for toast rather than for chicken. That flattening is expected. What it does not tell you is whether the body underneath is still improving, and at six months it very often is: waist still shrinking, strength still climbing, weight unchanged. That is recomposition, and the scale cannot see it.
Saxenda produces slower, steadier loss, so a six-month plateau on liraglutide tends to arrive after a smaller total. Intake creeping up as nausea settles is still the most common explanation.
What to check before you change anything
Measure the waist and the upper arm, not just the scale
Same spot, same time of day, in centimetres or inches. A waist that has come down 2 cm (0.8 in) over a month with no change on the scale means you are losing fat and holding muscle. That is the outcome you were after.
Log a week of food without editing it
Six months in, most people we coach are eating 300 to 600 calories (1,250 to 2,500 kJ) more than they were in month two, because nausea has gone and habits have returned. That alone explains most six-month plateaus.
Put protein back to the top of the range
1.6 g per kg of goal weight (0.7 g per lb) rather than the 1.2 floor. For a 70 kg (154 lb) goal, 112 g a day. Protein is the one macronutrient that protects muscle and keeps you fuller while the rest of the plate shrinks.
Add load to the two sessions rather than adding cardio
The answer to a plateau is rarely more walking. Heavier weights, or more reps at the same weight, on the same six movements, twice a week. Muscle is the tissue that keeps your resting energy use up.
Recalculate the target for your new weight
Six months of steady Saxenda loss means your goal-weight protein target may have changed. Run the calculator again and set the number against where you are heading, not where you started.
A six-month reset day, higher protein and real food
- Breakfast: 200 g (7 oz) Greek yoghurt with berries and 20 g of almonds, about 25 g protein
- Lunch: 150 g (5 oz) chicken with a large salad and olive oil, about 45 g
- Afternoon: 30 g scoop whey in 250 ml (8.5 fl oz) milk, about 33 g
- Dinner: 150 g (5 oz) lean beef or tofu with vegetables and a small serve of rice, about 40 g
Around 143 g of protein, which suits a goal weight near 90 kg (198 lb) at the top of the range. Hold this for four weeks and judge the waist, the strength test and the protein average rather than the scale.
Work out your own target on SaxendaWorth a conversation with your prescriber
- Whether your current dose is still the right one for you, which is entirely their decision and never one to adjust yourself
- A plateau alongside fatigue, hair shedding, feeling cold or low mood, which is worth a thyroid and iron test
- What your plan looks like from here, including how long you are expected to stay on the medication
Dose and timing on Saxenda are your prescriber's decisions; we coach the food and the strength.
The three numbers that tell you what you are keeping
At six months the scale is the least useful number you have. These three are the ones that still move.
One strength test, same way every week
Goblet squat reps at a fixed weight, push-ups, or the 30-second sit-to-stand for beginners. Fat loss does not make you weaker, so a number that drops three or four weeks running is a real signal, and it is fixable. It measures what you can do, not how much muscle you have.
Average protein a day, whole week
Not your best day. 1.2 to 1.6 g per kg of goal body weight (0.55 to 0.7 g per lb), floor 1.2, protein first at every meal.
Upper arm tape, same spot, relaxed
Centimetres or inches. The waist shrinks whatever you do; if the arm shrinks as fast, that is muscle. Weight is number four, same day and time. The scale tells you what you lost. These tell you what you kept.
Questions people ask
Is a plateau at six months on Saxenda normal?
It is the usual pattern. Trial weight curves flatten in the second half of the first year. A month without scale movement while your waist shrinks and your strength test climbs is progress, not a stall.
Should I eat less to break a six-month plateau?
Rarely. Most people at six months are already eating little, and cutting further usually costs muscle and energy rather than fat. Raise protein, add load to your strength sessions, and hold both for four weeks.
Why did I plateau on Saxenda sooner than expected?
Liraglutide's appetite effect is milder and steadier, so total loss tends to be smaller. If intake has also risen as nausea settled, the two together flatten the curve. Log a week and see.
The research behind this page
Six months in, the interesting question is what the weight you already lost was made of. These two figures answer it.
Lean mass as a percentage of body weight was unchanged in pooled trials, which is why people can lose real muscle and still look like the numbers are fine. Karakasis P et al, Metabolism 2025
Adding resistance training brought the lean share of weight lost down to 17.5%, the most favourable result of any approach studied. Eisa N et al, Diabetes, Obesity and Metabolism 2026
