Protein Calculator
Protein intake calculator
Protein is one of the most important nutritional factors in a successful GLP-1 journey. Getting enough protein protects your lean muscle mass, keeps you fuller for longer, and improves long-term outcomes. Use this calculator to find your personalised daily target based on your weight, activity level, and whether you are currently on GLP-1 therapy.

How much protein do you need on your GLP-1 journey?
Select your current weight and activity level below. If you are currently on GLP-1 therapy, toggle that option on — your target will increase to account for the higher protein needs that protect lean muscle mass during treatment.

Protect lean muscle on GLP-1
Up to 40% of weight lost on GLP-1 medication can come from muscle if protein intake is too low.[9] Higher protein preserves the muscle that keeps your metabolism strong.
Protein reduces hunger signals
Protein is the most satiating macronutrient.[10] Paired with GLP-1 therapy, adequate protein helps you stay full, reduces muscle loss, and supports recovery.

Everything you need to know about protein
Protein is the most critical nutrient to get right on your GLP-1 journey. Here is what it is, why it matters, and what shapes your daily requirement.
What is protein?
Protein is an essential macronutrient made up of amino acids that builds, repairs, and maintains the body’s tissues and cells. Often called the body’s building blocks, protein supports muscle growth, recovery, enzyme production, hormone function, and immunity — nearly every biological process your body depends on. In the Indian diet, protein comes from a mix of plant and animal sources; both are valid provided you meet your daily target. [4]
Why is protein important?
Adequate protein intake builds and repairs muscles, tissues, skin, and cells, while supporting hormone production, enzyme activity, immune function, and recovery. For Indians on a GLP-1 programme, protein is especially critical: it preserves lean muscle mass during caloric restriction, keeps you fuller for longer, and significantly reduces the risk of regaining weight after treatment ends. [5]
What influences your protein needs?
Protein requirements vary based on age, activity level, body weight, and life stage. They increase when you are losing weight, building muscle, or recovering from illness. For those following a predominantly plant-based diet — common across India — combining sources such as dal with rice or paneer with lentils helps ensure a full range of essential amino acids. [6] [7]
How much protein do you need per day?
Protein requirements vary depending on your activity level, health goals, and whether you are on GLP-1 therapy. Here is how to find your number — and why distributing it across meals matters as much as the total.
Daily requirements by activity level
The standard RDA is 0.8 g per kg of body weight per day for minimal activity. To support functional goals like muscle synthesis and strength, experts recommend: Minimal activity — ~1.0 g/kg/day · Moderate activity — ~1.3 g/kg/day · Intense activity — ~1.6 g/kg/day. On GLP-1 therapy, your target increases further to protect lean muscle — use the calculator above for your personalised estimate. [1]
Active adults and athletes
For Indians who exercise regularly, evidence-based guidelines recommend 1.2–2.0 g/kg/day to support exercise-induced muscle growth and recovery — whether your activity is strength training, running, swimming, yoga, or another regular practice. Higher protein intake combined with resistance training is the most effective strategy for preventing muscle loss during GLP-1 treatment. [2]
How to calculate your daily protein
Multiply your body weight in kg by your activity multiplier. Example: a 75 kg person with moderate activity needs approximately 75 × 1.3 = 97.5 g per day. Research shows the most effective approach is to distribute this across 3–4 meals, aiming for 0.25–0.40 g per kg of body weight per meal — eating all your protein at once is significantly less effective for muscle synthesis. [2] [8]

Frequently asked questions
GLP-1 medications such as Mounjaro and Wegovy significantly reduce appetite, which often means patients eat considerably less overall. Without deliberate attention to protein intake, a large proportion of that reduced intake can come from cuts to protein-rich foods. Research shows that up to 40% of weight lost during GLP-1 treatment can come from lean muscle mass rather than fat when protein intake is insufficient [9]. Muscle is metabolically active — losing it slows your metabolism and increases the risk of regaining weight after treatment ends. Higher protein intake preserves muscle while still allowing fat loss, which is the goal of the Karespot programme.
Spreading your protein intake across 3–4 meals during the day is more effective than trying to consume a large amount in one sitting. The body can only utilise roughly 25–40g of protein for muscle synthesis at once [11] — excess amounts are used for energy or excreted. A practical approach is to include a quality protein source at every meal: eggs, paneer, dals, chicken, fish, Greek yoghurt, or a plant-based alternative. Your Karespot dietician will build a specific meal structure around your daily target.
The best protein sources are those that are easy to digest, nutrient-dense, and filling. On GLP-1 therapy, appetite is reduced, so it is important that every meal delivers a meaningful amount of protein without excessive calories. Good sources include eggs, Greek yoghurt, paneer, tofu, legumes (dal, chana, rajma), lean meats (chicken breast, fish), and low-fat dairy. Avoid protein sources that are very high in saturated fat, as these may worsen GLP-1 side effects such as nausea [10].
Yes — this is one of the key risks to manage. GLP-1 medications reduce appetite non-selectively, meaning patients eat less of everything, including protein-rich foods [9]. This is why Karespot dieticians build protein-forward meal plans specifically calibrated to your GLP-1 dose stage. The goal is to make every calorie count for nutrition rather than simply reducing overall intake.
For most healthy adults, high-protein intakes in the ranges this calculator recommends are well-tolerated and safe. However, individuals with pre-existing kidney disease or significantly impaired kidney function should not follow high-protein targets without specific medical advice — elevated protein intake can increase the workload on the kidneys [12]. If you have any kidney conditions, please discuss your protein needs directly with your Karespot doctor before following the calculator's recommendation.
