Food noise and cravings returning between doses on Saxenda
If the quiet turns back into noise in the hours before your next injection, you have not done anything wrong and the medication has not stopped working. Saxenda is daily: Blood levels peak about eight to twelve hours after the injection, and as the level falls towards the next injection some appetite, and some of the old running commentary about food, can come back. Those hours are the part of the day to eat well in, not the part to fight. Put the largest protein meal of the day there, keep the plates small, and take what your appetite gives you. If appetite is strong all day, every day, or the medication never quietened it at all, that is a conversation for your prescriber rather than a reason to change anything yourself.
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 the quiet fades before the next dose
Liraglutide mimics the gut hormone GLP-1: it slows stomach emptying and brings fullness on sooner. Dosed daily and cleared within a day or two, its effect is steadier and milder than the weekly medications. A good part of what people call food noise, the constant low-level planning of the next thing to eat, is that signal being weak, so a medication that supplies it turns the commentary down. Blood levels peak about eight to twelve hours after the injection and the half-life is about 13 hours, which means the amount in your system is not flat between doses. It climbs, sits near its peak, and then drifts down until the next injection tops it up. The noise you hear late in the interval is the sound of the level falling, not the medication failing.
That falling tail is normal and, handled well, useful. It is the one part of the cycle when eating is easy, and eating is exactly what a body in a large deficit needs. 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 people we coach who lose the most muscle are often the ones who treat the hungry days as a test of willpower, eat almost nothing through them, and arrive at the next dose already short. The hungry days are for protein and for training. The quiet days coast on what they built.
Saxenda is daily, so the cycle runs inside each day rather than across a week. Levels peak about eight to twelve hours after the injection and the most appetite tends to arrive in the hours before the next one. Put the largest protein meal of the day in that window.
How to use the noisy days instead of fighting them
Move the big protein meals to the tail
If hunger returns on days five to seven of a weekly dose, that is when 35 to 40 g meals are possible without effort. Chicken, fish, eggs, Greek yoghurt, lean mince: cook the real food then and let the quiet days run on shakes and cold protein.
Put both strength sessions in the same window
Two 30-minute sessions a week, and appetite and energy are both highest at the tail. Training on a day you can also eat is the combination that holds a strength test steady in a deficit.
Answer the noise with protein first, then decide
A craving at 4pm on a hungry day is usually a body that has had 50 g of protein by then instead of 80 g. Eat 30 g of something, wait twenty minutes, and see what is left of the thought. Most of it goes.
Keep the plate small and the meals frequent
Fullness still arrives early even when hunger is back, and a large plate on a slowed stomach is how the tail days turn into nausea. Four meals of 30 to 35 g rather than two of 60 g.
Find the hungry hours and feed them protein
On daily Saxenda the appetite returns in the hours before the next injection. Put your 35 to 40 g meal there every day, at the same time, and the rest of the day can run on smaller cold protein.
A hungry-day plan at about 120 g of protein
- Breakfast: 3 eggs scrambled with 30 g (1 oz) cheese on one slice of toast, about 27 g
- Lunch: 120 g (4 oz) chicken breast in a rice and salad bowl, about 38 g
- Afternoon: 200 g (7 oz) Greek yoghurt with a handful of berries, about 20 g
- Dinner: 150 g (5 oz) lean beef mince with potato and greens, about 36 g
Around 120 g, all of it on a day when eating is easy. The quiet days that follow only need to reach the floor of 1.2 g per kg of goal weight (0.55 g per lb), because this one has already carried the weekly average.
Work out your own target on SaxendaWhen the returning appetite belongs with your prescriber
- Hunger and food noise that run all day, every day, or that never eased at all, which is information your prescriber needs rather than something to manage by eating less
- Any thought of moving your injection time or changing the amount to cover the hungry hours: those are prescribing decisions, never ours and never yours alone
- Cravings that arrive with shakiness, sweating or confusion, particularly if you also take insulin or a sulfonylurea, which need same-day advice
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
The noisy days feel like failure and the quiet days feel like success. These three numbers ignore both feelings and tell you what is being kept.
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
Why does my appetite come back before my next Saxenda dose?
Blood levels peak about eight to twelve hours after the injection and then the level falls until the next injection. As it falls, some of the appetite it was holding down returns. It is the normal shape of the dose interval rather than a sign the medication has stopped working.
Should I eat less on the days I feel hungry?
No. Those are the days your body can take a proper protein meal and a strength session, and both are what protect muscle in a deficit. Eat protein first at each meal, keep the plates small, and let the quiet days run lighter.
When is appetite strongest on Saxenda?
Usually in the hours before the next daily injection, as the level from the previous one falls. That is where the largest protein meal of the day belongs, kept at 35 to 40 g and eaten at the same time each day.
The research behind this page
A craving is often a protein shortfall arriving late. These are the numbers that decide whether your day had one.
Spread across meals at roughly 0.3 to 0.4 g per kg per meal, rather than taken mostly at dinner. Arslan S, Clinical Nutrition ESPEN 2026
Each of those meals wants roughly 2.5 to 3 g of leucine, the amino acid that actually switches muscle building on. That is about 30 g of whey, 120 g of chicken breast, or four eggs. Arslan S, Clinical Nutrition ESPEN 2026
