What to Eat When You Have No Appetite on GLP-1 UK

One of the most powerful effects of GLP-1 medication is appetite suppression — but for many people, particularly after dose increases, appetite reduction goes further than expected. Not just less hungry, but genuinely indifferent to food. When you can only eat small amounts, what you eat matters enormously.

Quick answer: when appetite is very low on GLP-1, prioritise protein above everything else — eat the protein component of any meal first, before vegetables, before carbohydrates, before anything else. If you can only eat 200–300 calories, make them count: protein shakes, cottage cheese, Greek yoghurt, eggs, and tinned fish provide the most protein per calorie with the least eating effort.

Why protein is the priority when appetite is suppressed

When total food intake drops significantly, the body needs adequate protein to preserve muscle rather than breaking it down alongside fat. Each kilogram of muscle lost reduces resting metabolic rate by approximately 13 calories per day — permanently, until muscle is rebuilt. On GLP-1 medication, where calorie restriction can be significant, adequate protein determines whether you are losing fat or fat plus muscle.

The protein-first rule on GLP-1

At every meal and snack, eat the protein component first — before anything else. When appetite gives out halfway through a meal (which it frequently does on GLP-1), the protein has already been consumed. This single rule is the most practical eating approach on appetite-suppressing medication.

Best foods when appetite is very low

Food	Protein	Calories	Why it works on GLP-1
Greek yoghurt (0%), 200g	20g	~115 kcal	High protein, easy to eat, no cooking required
Cottage cheese, 150g	17g	~130 kcal	Soft texture, mild flavour, zero effort
Protein shake with milk	30–40g	~250 kcal	Liquid — easier when solids are unappealing
Scrambled eggs (2 whole + 1 white)	20g	~185 kcal	Soft, quick, easy to eat small amounts of
Tinned tuna, 145g tin	30g	~145 kcal	No cooking, highest protein per calorie
Chicken broth with shredded chicken	25g	~150 kcal	Warm, easy to consume even with nausea
Smoked salmon, 100g	20g	~160 kcal	No cooking, omega-3s included

What to avoid when appetite is very low

Filling up on vegetables alone — high volume, minimal protein, displaces protein sources
Liquid calories from juice or smoothies — calories without satiety value
Carbohydrate-heavy meals as the main component — bread, pasta, rice are low protein per calorie
Large portions — on GLP-1, the stomach empties more slowly; large meals cause significant discomfort
