How much protein do guidelines suggest on Ozempic or Mounjaro?

How much protein do guidelines suggest?

For healthy Indian adults, ICMR-NIN sets the protein allowance at 0.83 g per kg of body weight a day.¹ Higher figures have been proposed during weight loss.²

ICMR-NIN is the Indian Council of Medical Research's nutrition institute in Hyderabad. Its 2024 guidelines call 0.83 g per kg the recommended dietary allowance (RDA).¹ For a 65 kg person, that is 54 g a day, whatever their activity level or sex.¹

Ozempic contains semaglutide (is semaglutide the same as Ozempic?).¹⁷ Mounjaro contains tirzepatide (what is tirzepatide?).¹⁰ The GLP-1 panels below cover semaglutide and tirzepatide among these medicines.^2,3,4

These figures describe groups of people. A doctor or dietitian works out an individual amount. Here is what each source says:

• ICMR-NIN (India, healthy adults): 0.83 g per kg a day.¹ Above about 1.6 g per kg, it says, extra protein adds no more muscle with strength training.¹
• US advisory, 2025 (on GLP-1 medicines): 1.2–1.6 g per kg a day has been "proposed during active weight reduction".² A flat 80–120 g a day is its alternative.² Four US nutrition and obesity groups wrote this advisory.²
• Indian consensus, 2026 (on these medicines): it recommends starting from 0.8 g per kg and building up "to 1.2–1.5 g/kg/day or higher".³ The studies it cites went up to 1.6 g only with normal kidney function.³
• International expert consensus, 2025: 1.2–1.5 g per kg of actual body weight while losing weight.⁴ Once weight is stable, at least 0.8 g.⁴
• US dietary guidelines 2025–2030 (all Americans): 1.2–1.6 g per kg a day.⁸ This is a US figure for the general population, not an Indian or GLP-1 one.

The US advisory also sets limits. Intake should not fall below 0.4–0.5 g per kg a day.² It says 2 g per kg or more should be avoided over the long term.²

A worked example. For a 70 kg adult, 0.83 g per kg is about 58 g a day. At 1.2–1.6 g per kg it is 84–112 g, and 2 g per kg is 140 g. This is our arithmetic, not a target for anyone.

Why do the protein figures differ, and who wrote them?

The higher GLP-1 figures come mostly from expert opinion and other weight-loss research. They don't come from trials of these medicines.⁴

The 2025 international consensus says there is "a significant lack of direct evidence" to guide care.⁴ Its statements were "primarily derived from indirect evidence", including guidance for weight-loss surgery.⁴ It cites a review of 129 trials of these medicines. That review found little reporting of what people actually ate.⁴

Which body weight? The sources also differ on which weight to multiply. The US advisory says actual weight "can significantly overestimate" protein needs in people with obesity.² The international consensus uses actual weight, but notes the same risk of overestimating.⁴

Who paid. The US National Institutes of Health funded the US advisory.² Five of its authors report advisory or speaker roles with Novo Nordisk or Eli Lilly, which make these medicines.²

Abbott Nutrition International, India, funded the Indian consensus. Two of its 15 authors work at Abbott Healthcare.³ All 15 authors report grants or contracts from Abbott Healthcare, and 12 report Abbott fees for educational talks.³ The funder had no role in the design or writing, the paper says.³

Nestlé Health Science funded the international consensus.⁴ It also paid for project management and medical writing support.⁴

Every figure on this page is multiplied by body weight, and India uses its own BMI cut-offs. Healthy is 18.0–22.9, overweight 23–24.9 and obesity 25 or more.¹¹ More is in Guide 1: weight and health in Indians.

Why can protein be harder to eat on a GLP-1?

GLP-1 medicines reduce appetite. The US advisory says less appetite or a dislike of some tastes can make protein hard to eat.²

Its practical tip is to eat the protein part of a meal first.² Decreased appetite is among the most common side effects (5% or more of people) on the US Mounjaro label.¹⁰

Where Indian diets start. The ICMR-INDIAB survey recorded what 18,090 adults across India usually eat.⁶ Protein gave 12% of their daily energy.⁶ The survey authors compared this with a 15% guideline.⁶ ICMR-NIN's 2024 guidelines call 10–15% of energy from protein ideal.¹ Most came from plants (8.9% of energy), then dairy (2.1%) and other animal foods (1%).⁶

Protein can slow the stomach too. The US advisory says protein- or fat-rich foods slow stomach emptying and can worsen constipation.² On the EU Wegovy label, constipation is very common (more than 1 in 10 people).¹⁵ The EU Mounjaro label gives it the same band in its weight-management trials.¹⁶ It has its own Answer: Constipation on a GLP-1.

Which Indian foods have the most protein?

In the table below, soybean, dals and groundnuts have the most protein, about 22–36 g per 100 g raw.⁵

The tables are ICMR-NIN's Indian Food Composition Tables 2017 (IFCT). It covers 528 key foods, using samples averaged across 6 regions of India.⁵ Vegetarian foods come first below, then non-vegetarian.

Protein per 100 g: IFCT 2017, Table 1, edible portion, raw (egg boiled), with IFCT food codes.⁵ IFCT gives no serving sizes. The amounts are our round choices. ICMR-NIN uses 30 g of raw pulses when it swaps pulses for meat.¹ The last column is our arithmetic, rounded to whole grams. Checked 5 Oct 2026.

IFCT lists these foods raw (eggs boiled). So the numbers fit dry or raw weights, not a cooked katori.⁵ IFCT 2017 has no entry for curd (dahi), tofu or soya chunks, so they have no number here.

Cereals add protein too. IFCT lists wheat atta at 10.57 g per 100 g and raw milled rice at 7.94 g.⁵ Paneer is high in fat as well as protein, at 24.78 g of fat per 100 g.⁵

How do vegetarians get enough good-quality protein?

ICMR-NIN says varied vegetarian or vegan diets can supply enough protein. Mixing cereals with pulses improves its quality.¹

Protein is built from 20 amino acids. The body can't make 9 of them, so they must come from food (essential amino acids).¹ Cereals are low in one of these, lysine, and pulses are low in another, methionine.¹ Eating about 3 parts cereal to 1 part pulse, by raw weight, covers them all.¹ Adding 250 ml of milk a day helps further.¹

Pulse protein costs less than protein from meat, eggs or milk, ICMR-NIN notes.¹ Most vegetarian foods are 70–85% digestible for protein.¹ The Indian consensus lists lean meat, milk, milk products and tofu as good-quality protein.³

One vegetarian day, as sums. Take 60 g raw moong dal (14 g protein) and 200 g milk (7 g). Add 100 g paneer (19 g) and 30 g groundnuts (7 g). That is 47 g. Add 150 g of atta for rotis (16 g) and the day reaches about 63 g. These are our sums from IFCT, not a meal plan or a target.⁵

Which non-vegetarian foods do guidelines favour?

The US advisory favours seafood, eggs and lean poultry. It suggests keeping red and processed meat low or moderate.²

In general populations, it says, red and processed meat are linked to type 2 diabetes, heart disease and bowel cancer.² For non-vegetarians, ICMR-NIN suggests 700–900 g a week of fish, poultry or lean meat, or eggs.¹ Its own swap is 80 g of meat for 30 g of pulses.¹

Per 100 g raw, IFCT lists skinless chicken breast at 21.81 g of protein.⁵ Goat leg has 22.07 g and rohu 19.71 g.⁵ A 50 g boiled egg gives about 7 g, by our arithmetic.⁵ Swap the paneer above for 100 g of chicken breast, and the day gives about 66 g (our arithmetic).

Is a high-protein diet safe with kidney disease?

ICMR-NIN says high-protein diets may worsen existing kidney disease. People with kidney disease should take them with care.¹

KDIGO (Kidney Disease: Improving Global Outcomes) writes international kidney guidelines. Its 2024 guideline suggests 0.8 g per kg a day in chronic kidney disease stages 3 to 5.⁷ Those stages mean a kidney filtering rate (eGFR) below 60.⁷ It advises avoiding more than 1.3 g per kg a day when kidney disease is at risk of getting worse.⁷

For a 70 kg adult, 1.3 g per kg is 91 g a day. That is below the top of the 1.2–1.6 g range quoted for weight loss. This is our arithmetic. The Indian consensus cites studies using up to 1.6 g per kg only "in individuals with normal kidney function".³

Kidney stones. After kidney stones, the US advisory suggests avoiding high-oxalate foods, highly processed foods and animal protein.²

A second kidney link. On these medicines, vomiting or diarrhoea can cause dehydration. That may cause kidney problems, the US Wegovy label says.⁹ The advisory says this can happen "with or without existing kidney disease".² More is in GLP-1 medicines and your kidneys and Guide 5: side effects and risks.

What do the sources say about protein powders?

ICMR-NIN says high protein intake, especially from supplement powders, is not advisable. The US advisory says some people reach targets with shakes or bars.^1,2

Powders are made from egg, milk, whey, soy, pea or rice, ICMR-NIN says.¹ They may contain added sugar, sweeteners and flavourings.¹ It adds that supplements on top of a balanced diet do not build more muscle.¹

The Indian consensus says nutrition should not lean on one nutrient, such as "only protein supplementation".³ Its panel also highlighted calorie-controlled meal replacements.³ Powders and gym supplements get their own Answer: Protein powder and supplements on a GLP-1.

Does eating more protein protect muscle on its own?

The US advisory says more protein alone is likely not enough to keep muscle. Structured strength training is needed too.²

It adds that protein beyond what muscles need can be turned into fat by the liver.² ICMR-NIN says protein isn't used to build muscle without enough activity or strength exercise.¹ The body also needs enough carbohydrate and fat to use it.¹
