Weight loss advice can often feel like loud opinions and silent results. Some people swear by chicken and eggs, others feel lighter with tofu and legumes, and many in India rely on paneer and curd for their protein fix. Consultant Nutritionist Rupali Datta says the real question is not which diet group is superior, but which protein source supports better satiety, a steady metabolism, and sustainable fat loss for each person.
“There is no single best protein source for everybody,” she says. “For weight loss, the protein that keeps you satisfied for longer tends to work better.”
Protein plays a crucial role in controlling appetite, preserving muscle mass while losing fat, and avoiding energy dips. Here is a clear breakdown of vegetarian, vegan, and meat protein and how each affects weight management.

Why Protein Type Matters When You Want To Lose Weight
Protein has the highest thermic effect among macronutrients, meaning the body burns more calories digesting it compared to carbohydrates or fat. Rupali Datta explains that the quality and digestibility of protein influence how full a person feels and how well muscles recover during a calorie deficit.
Better digestibility and a complete set of essential amino acids usually translate into better weight-loss support.
What Is Included In Vegetarian Protein
Most Indian vegetarian diets offer a good mix of plant-based foods along with dairy. Rupali Datta explains that this makes it easier to get a complete amino acid profile through familiar staples. Paneer, curd, and yoghurt help keep hunger at bay for longer while supporting muscle retention.
Examples of Vegetarian Protein Sources:
- Paneer (Cottage Cheese): 18 to 20 g per 100 g
- Greek Yoghurt (Hung Curd): 10 g per 100 g with probiotics
- Lentils (Dal): 7 to 9 g per 100 g cooked
- Chickpeas (Chana): 8 to 10 g per 100 g cooked
- Quinoa: 8 g per cooked cup and a complete protein
Vegetarian protein can easily support all essential amino acids, especially when dairy is included. Paneer and yoghurt also provide calcium and vitamin B12, which help maintain strong bones and nerve health.
This category also supplies dietary fibre from plant foods, something animal protein does not offer.
What Is Included In Vegan Protein
Vegan protein sources are naturally rich in fibre, which supports fullness and gut health. Rupali Datta notes that a well-planned vegan diet can be highly effective for fat loss.
Examples of Vegan Protein Sources:
- Hemp Seeds: 30 g protein per 100 g
- Tempeh: 20.7 g per 100 g
- Tofu: 8 to 10 g per 100 g
- Chia Seeds: 16.5 g per 100 g
- Lentils: 8.8 g per 100 g cooked
- Peanuts: 25.8 g per 100 g
Many plant proteins lack one essential amino acid, but the solution is simple. Combining foods such as grains and legumes throughout the day supports complete nutrition. Vegans should keep an eye on vitamin B12, iron, zinc, and omega-3 intake, ideally through fortified foods or supplements if required.
What Is Included In Meat Protein
Animal protein provides the highest bioavailability, which means better muscle preservation while cutting calories. Lean meats score strongly for weight-loss diets.
Examples of Meat Protein Sources:
- Chicken Breast: 25 to 30 g per 100 g
- Shellfish (Prawns, shrimp): 22 g per 100 g
- Fish (Salmon, Tuna): 20 to 25 g per 100 g
- Pork: 18 to 20 g per 100 g
- •Eggs: 6 g per egg
Rupali Datta advises prioritising lean cuts and fish for weight control, while keeping red and processed meats limited.

Nutritional Comparison: Vegetarian vs Vegan vs Meat Protein
| Aspect | Vegetarian Protein | Vegan Protein | Meat Protein |
| Amino Acid Profile | Mostly complete with dairy | Combinations required | Complete |
| Digestibility | Good | Slightly lower | Highly digestible |
| Saturated Fat | Low to moderate | Very low | Can be high in red meat |
| Fibre | High from plants | High | None |
| Cholesterol | Present in dairy | Zero | Present |
| Weight Loss Support | Good with dairy moderation | Good with planning | Very strong, especially lean meats |
“No single category is perfect,” says Rupali Datta. “Balance is key.”
How Much Protein Do You Need Daily?
Protein needs depend on age, weight, and activity level.
| Category | Daily Protein Needs | Notes |
| Sedentary Adults | 0.8 g per kg of body weight | Minimum intake |
| Active Individuals | 1.0 to 1.2 g per kg | For regular exercise |
| Strength or Muscle Gain | 1.4 to 2.0 g per kg | Supports better recovery |
| Older Adults (50 plus) | 1.0 to 1.3 g per kg | Helps protect muscle mass |
Example:
A 60 kg person who works out three times weekly needs about 72 g of protein a day.
Quick reference chart:
- 100 g paneer = 18 to 20 g protein
- 2 eggs = 12 g protein
- 100 g chicken breast = 25 to 30 g protein
- 1 cup cooked lentils = 7 to 9 g protein
Which Protein Works Better For Weight Loss? Expert Explains
Rupali Datta breaks it down simply:
- Lean meat (like chicken and fish)
“It usually offers the best satiety for fewer calories.” - Dairy (like Greek yoghurt and paneer)
“A steady and satisfying choice, especially for vegetarians.” - Vegan protein
“Very effective when fibre-rich foods and complementary proteins are included.”
Her key advice:
“Choose proteins that fill you up and fit your lifestyle. Weight loss is easier when the food supports energy and satisfaction.”
Which Protein Should You Choose For Your Weight Goals?
| Goal | Best Suited Protein | Why |
| Faster fat loss | Lean meats, Greek yoghurt | Highest satiety |
| Weight management on a vegetarian diet | Paneer, lentils, quinoa | Balanced nutrition |
| Heart-focused weight control | Vegan sources | Lower saturated fat |
| Anaemia concerns | Meat, dairy, eggs | Better iron and B12 absorption |
| Over 50 years | Dairy, fish, soy | Protects muscle mass |
Common Protein Deficiencies And How To Address Them
| Nutrient | Who Is At Risk | What To Add |
| Vitamin B12 | Vegans, some vegetarians | Fortified cereals, B12 supplements |
| Iron | Vegans, menstruating women | Leafy greens and beans with vitamin C |
| Calcium | Strict vegans | Ragi, tofu, almonds, fortified plant milk |
| Omega 3 | Vegans | Chia, flaxseed, walnuts, algae oil |
Small additions can cover nutritional gaps effectively.

A Balanced Plate Wins Every Time
Rupali Datta says the most successful diet is the one that feels sustainable. Protein helps keep hunger steady and muscles strong, but it must work with real life and food preferences.
