Vegetarian Diet Plan for Weight Loss

Eating a vegetarian diet while taking GLP-1 medication such as Mounjaro or Wegovy is entirely achievable, but it requires some extra attention to protein, iron, and overall balance. Appetite suppression and slower digestion can make it more difficult to get enough nutrients from smaller portions.

This guide explains how to eat well as a vegetarian on GLP-1s, which foods to focus on, and how to manage side effects like nausea or bloating.

GLP-1 receptor agonists slow digestion and reduce hunger, which can limit the total amount of food you eat. Vegetarian diets, while healthy, often rely on high-fibre plant foods that can feel heavy or cause discomfort when eaten in large portions.

GLP-1 users following vegetarian diets should focus on:

• Protein quality: Combining plant proteins to ensure adequate amino acids
• Iron and B12 intake: Sourcing or supplementing essential nutrients often found in meat
• Digestive comfort: Choosing cooked and softer textures for better tolerance

Prioritise protein at each meal

Vegetarian GLP-1 users need to be intentional about protein. Include foods such as:

• Eggs and dairy products (if not vegan)
• Tofu, tempeh, and soy yoghurt
• Lentils, beans, and chickpeas
• Quinoa, buckwheat, and amaranth
• Protein-enriched yoghurts or powders

See Protein Powders on GLP-1s for safe supplement options.

Watch fibre intake

Fibre supports digestion but can increase bloating on GLP-1s. Opt for cooked vegetables, blended soups, or soft pulses rather than large salads.

Include iron and B12 sources

Plant sources of iron include lentils, beans, and spinach. Pair them with vitamin C (such as peppers or citrus) to aid absorption. Most vegetarians will also benefit from a B12 supplement — see Supplements and GLP-1s.

Add healthy fats for comfort and energy

Include nuts, seeds, and avocado in moderation. These provide lasting energy when your appetite is small.

Breakfast – Oats with soy milk, chia seeds, and banana

Lunch – Lentil soup with wholegrain bread

Snack – Greek yoghurt with soft fruit

Dinner – Tofu stir-fry with rice and cooked vegetables
