If your appetite is smaller than it used to be — whether you're on a GLP-1 medication, eating in a calorie deficit, or just not very hungry — the single most important thing to protect is your protein intake. Eating less makes it easy to fall short of the protein your body needs to preserve lean muscle while you lose fat. The fix is simple: choose small-format, nutrient-dense, high-protein snacks that deliver 15–30 g of protein in just a few bites or sips. Below is our Canadian shortlist of in-stock, high-protein, lower-calorie options, plus answer-first guidance on how much protein you need and what to look for on the label.

Why is protein so important when your appetite is reduced?
When you eat less, protein is the macronutrient you can least afford to cut. In any calorie deficit your body can break down lean muscle for energy, and dietary protein paired with resistance training is what helps preserve it — so more of the weight you lose comes from fat. Small, protein-dense foods let you reach your daily target even on days you can only manage a few mouthfuls. That's exactly why compact, high-protein snacks matter so much during an appetite-support journey.
How much protein per day do you need to preserve muscle?
A widely cited target for preserving lean mass in a deficit is roughly 1.6–2.2 g of protein per kilogram of body weight (about 0.7–1.0 g per pound) per day — for many adults, somewhere between 100 and 150 g daily. Because a reduced appetite makes large meals hard, it helps to spread protein across smaller servings of 20–30 g throughout the day. A bar mid-morning, a shake in the afternoon and a savoury snack in the evening can add up to your goal without ever feeling like a heavy meal.
What are the best small high-protein snacks when you can't eat much?
The best options are single-serve, portionable and protein-dense — 15 to 30 g of protein without a big volume of food. Our top picks for Canadian customers, all in stock:

What should you look for on the label — protein-per-calorie and fibre?
Two numbers matter most. Protein-per-calorie: an appetite-friendly snack delivers a high share of its calories as protein — David's bar (about 28 g protein for ~150 calories) is a standout. Fibre and sugar: higher-fibre, lower-sugar choices like Warrior Crunch help you feel full and support digestion, which can slow down when you're eating less. Favour complete protein sources — whey isolate, dairy and meat — and keep added sugar low. For pure muscle-preservation protein, a clear whey isolate or a classic isolate like Allmax Isoflex anchors your daily total without a heavy, filling shake.
Does resistance training matter for keeping muscle while eating less?
Yes — it's the other half of the equation. Protein supplies the building blocks, but resistance training (weights or bodyweight strength work, two to four times a week) is the signal that tells your body to hold onto muscle while you lose fat. The best-supported approach for preserving lean mass in a deficit is hitting your daily protein target and training your muscles regularly. The snacks above make the protein half effortless.
Where to start: muscle-preservation protein powders

High-protein appetite-support snacks: frequently asked questions
Why is protein so important when your appetite is reduced?
When you eat less, protein becomes the macronutrient you can least afford to skimp on. During any calorie deficit your body can break down lean muscle for fuel, and dietary protein plus resistance training is what helps preserve that muscle. Smaller, protein-dense foods let you hit your daily target even on days when you can only manage a few bites, so more of the weight you lose comes from fat rather than muscle.
How much protein per day do you need to help preserve muscle?
A widely cited range for preserving lean mass in a calorie deficit is roughly 1.6 to 2.2 grams of protein per kilogram of body weight per day (about 0.7 to 1.0 gram per pound). For many adults that lands somewhere between 100 and 150 grams daily. Spreading it across smaller meals and snacks — 20 to 30 grams at a time — is easier on a reduced appetite than two or three large meals. This is general nutrition information, not medical advice; talk to your healthcare provider about what is right for you.
What are the best small high-protein snacks when you can't eat much?
Look for compact, single-serve formats that deliver 15 to 30 grams of protein without a large volume of food. Protein bars like David, Barebells, Built and Grenade pack 17 to 28 grams into one bar. Bite-sized options like ProBites let you portion down even further. Savoury picks — Quest Protein Chips or a Bowmar meat stick — help when sweet foods feel unappealing. On low-appetite days, drinkable protein like a sparkling protein water, an RTD shake or a clear whey isolate often goes down more easily than solid food.
What should you look for on the label — protein-per-calorie and fibre?
Two numbers matter most. First, protein-per-calorie: a strong appetite-friendly snack delivers a high share of its calories as protein — David's bar (about 28 g protein for ~150 calories) is a standout example. Second, fibre: higher-fibre, lower-sugar snacks like Warrior Crunch help you feel full and support digestion, which can be sluggish when you're eating less. Keep added sugar low and prioritise complete protein sources such as whey isolate, dairy and meat.
Does resistance training matter for keeping muscle while eating less?
Yes — it's the other half of the equation. Adequate protein gives your body the building blocks, but resistance training (lifting weights or bodyweight strength work two to four times a week) is the signal that tells your body to hold onto muscle while you lose fat. Pairing daily protein targets with regular strength training is the best-supported combination for preserving lean mass in a deficit.
Can you use these snacks on a GLP-1 medication or appetite-support journey?
These are foods and supplements, not medications, and they don't treat, replace or interact with any prescription. People whose appetite is reduced — whether from a GLP-1 medication, a busy schedule or simply eating in a deficit — often struggle to reach their protein goal, and small-format, protein-dense options make that easier. Always follow your prescriber's and dietitian's guidance for your own plan; we're here for the nutrition side.
