Nutrition & Training Guide
The Ultimate Food & Nutrition Guide to Help Grow Your Glutes and Booty
Everything you need to know about eating for stronger, fuller glutes — from the right foods and macronutrients to meal timing and the common mistakes that are quietly holding you back.
Growing your glutes is one of the most popular fitness goals right now — and for good reason. A stronger, rounder posterior isn’t just about aesthetics; well-developed gluteal muscles support your hips, protect your lower back, improve your posture, and make you more powerful in almost every athletic movement you perform.
But here’s what most guides get wrong: they focus almost entirely on training while treating nutrition as an afterthought. The truth is that your glute-building nutrition strategy is every bit as important as the exercises you do. Without the right foods in the right amounts at the right times, your body simply doesn’t have the raw materials to build new muscle tissue — no matter how many hip thrusts you’re doing.
This guide cuts through the noise. Drawing on current nutritional science and the coaching experience we’ve built at Optimo Coach, we’re going to walk you through precisely what to eat, why it works, and how to build a realistic approach that fits your life.
Whether you’re working with us through our 3-Month Glute & Booty Programme, training in person across London, or following along from anywhere in the world through our online coaching, this guide applies to you.
Why Nutrition Is Non-Negotiable for Glute Growth
Your gluteus maximus is the largest single muscle in the human body. Building it — genuinely adding new muscle tissue rather than simply reducing body fat around it — requires a process called muscle protein synthesis (MPS). This is when your body takes amino acids from the food you eat and uses them to repair and grow muscle fibres that have been stressed through training.
Research published in 2025 in the Journal of Health, Population and Nutrition confirmed that resistance training combined with adequate nutritional support — particularly protein sources rich in essential amino acids — synergistically enhances skeletal muscle protein synthesis and promotes hypertrophy. In plain terms: the training creates the stimulus, but food provides the building blocks.
There are three nutritional pillars your glute-building diet needs to stand on:
- A sufficient caloric environment — you need enough total energy to support muscle growth
- Adequate protein intake — to fuel muscle protein synthesis
- Strategic carbohydrate and fat balance — to fuel workouts and support hormonal health
Get these three things right, and the specific foods you choose to fill them with will do the rest.
How Much Protein Do You Actually Need to Grow Your Glutes?
Protein is the single most important macronutrient for building muscle. Your glutes are made of muscle fibres, and those fibres require a constant supply of amino acids — particularly the essential amino acids your body cannot produce on its own — to repair, adapt, and grow after training.
A 2025 review published in Nutrients (Mănescu et al.) found that protein and essential amino acids showed consistent benefits for muscle hypertrophy when daily intake was below 1.6 g per kilogram of body weight, with effects plateauing around 2.0 g/kg/day. A separate 2025 study found that individuals who consistently hit over 2.0 g/kg/day experienced superior muscle and strength gains during an 8-week hypertrophy programme compared to those consuming less.
The practical recommendation for most women looking to grow their glutes:
Daily Protein Target for Glute Building
Aim for 1.6 to 2.2 g of protein per kilogram of your body weight each day, spread across 3–4 meals. For a 65 kg woman, that’s roughly 104–143 g of protein daily.
Equally important is how you distribute that protein. The International Society of Sports Nutrition recommends doses of 20–25 g every three to four hours to maximise muscle protein synthesis rates. This means a single high-protein dinner won’t cut it — your body needs a steady supply throughout the day.
The Best Protein Sources for Glute Growth
Not all proteins are equal. Complete proteins — those containing all nine essential amino acids — are the most effective for driving MPS. The leucine content of a protein source is particularly important, as research indicates you need around 2–3 g of leucine per meal to trigger maximum protein synthesis. Here are the top sources to prioritise:
| Food | Protein per 100g | Why It Works for Glutes |
|---|---|---|
| Chicken breast | ~31 g | Lean, complete protein; high leucine content |
| Salmon | ~25 g | Protein + omega-3s to reduce post-training inflammation |
| Eggs (whole) | ~13 g | Highly bioavailable; yolk supports hormone health |
| Greek yoghurt (full-fat) | ~10 g | Contains casein for sustained amino acid release overnight |
| Tempeh | ~19 g | Best plant-based complete protein; fermented for gut health |
| Cottage cheese | ~11 g | High casein; excellent before bed to support overnight recovery |
| Lentils | ~9 g (cooked) | Plant protein + complex carbs; pair with rice for complete amino acid profile |
If you’re training at home or prefer plant-based options, our guide on natural supplements for muscle building covers additional ways to top up your protein intake without relying on processed powders.

Carbohydrates: Your Glutes’ Secret Weapon
Carbohydrates have been unfairly demonised in fitness culture. For anyone training seriously to build their glutes, carbs aren’t the enemy — they’re an absolute necessity. Here’s why.
When you train your glutes with compound movements like hip thrusts, Romanian deadlifts, and Bulgarian split squats, your muscles rely primarily on glycogen — the stored form of glucose — for fuel. If your glycogen stores are depleted because you’re eating too few carbohydrates, your workouts become shorter, less intense, and less effective. You simply can’t train as hard, and training hard is what creates the hypertrophic stimulus in the first place.
Carbohydrates also play a critical role in the recovery process. Consuming carbohydrates after training replenishes glycogen stores and triggers an insulin response that helps shuttle amino acids into muscle tissue — effectively amplifying the muscle-building effect of your post-workout protein.
The Best Carbohydrate Sources for Glute Building
The key is choosing carbohydrates that provide sustained energy, support hormonal health, and deliver useful micronutrients alongside their calories. The following are consistently the most effective choices our coaches at Optimo Coach recommend:
Sweet potatoes are arguably the single best carbohydrate source for glute growth. They’re rich in complex carbohydrates that digest steadily without spiking blood sugar, and they’re packed with potassium, vitamin A, and vitamin C — all of which support muscle function and recovery. A medium sweet potato provides around 27 g of carbohydrates and sits comfortably within a muscle-building meal plan.
Brown rice and oats are reliable staples. Brown rice is particularly versatile alongside protein sources like chicken or salmon, while oats provide soluble fibre and a slow-release energy source that’s ideal in the hours before training. Oats also contain a modest amount of protein, making them a surprisingly useful contribution to your daily intake.
Quinoa deserves special mention because it’s one of very few plant-based foods that qualifies as a complete protein while also acting as a significant carbohydrate source. If you’re following a plant-based diet or simply want more dietary variety, quinoa is an excellent addition to any glute-building meal plan.
Whole grain bread and pasta are practical choices that make it easy to hit your carbohydrate targets without complicated meal prep. Choose wholegrain varieties over refined white versions to slow digestion and support more stable energy throughout the day.
Fruits — particularly bananas, berries, and mangoes — provide fast-digesting carbohydrates that are particularly well-suited to the period immediately before or after training. Bananas, high in potassium and natural sugars, are a simple and highly effective pre-workout energy source.
Healthy Fats: Why They Matter More Than You Think
Dietary fat is essential for glute growth for several reasons that go beyond simple calorie provision. Fats are the raw material for producing steroid hormones — including oestrogen and testosterone — both of which play a significant role in how efficiently your body builds and retains muscle. Women who eat chronically low-fat diets often experience hormonal disruption that makes muscle growth significantly harder.
Additionally, fat-soluble vitamins (A, D, E, and K) are only absorbed in the presence of dietary fat. Vitamin D, in particular, has been linked to muscle function and strength in numerous studies, making it especially relevant for glute development.
Omega-3 Fatty Acids and Glute Recovery
Omega-3 fatty acids deserve particular attention. Research has shown that omega-3 fats reduce exercise-induced inflammation, which can accelerate muscle recovery and allow you to train your glutes more frequently. A 2025 review in Nutrients identified omega-3s (at around 1–2 g per day) as supporting training tolerance and recovery — key factors when you’re pushing hard in the gym.
The best dietary sources of omega-3s are oily fish — salmon, mackerel, sardines, and trout are all excellent choices and widely available across UK supermarkets. If you follow a plant-based diet, flaxseeds, chia seeds, and walnuts provide ALA (a precursor to the more active forms of omega-3), while algae-based supplements offer a direct source of EPA and DHA.
Other Beneficial Fat Sources
Avocado is a particularly versatile source of monounsaturated fats that also provides potassium, magnesium, and folate — nutrients that support muscle function and energy metabolism. Half an avocado added to your lunch is a simple, practical way to boost your healthy fat intake.
Whole eggs — including the yolk — provide a complete fat profile alongside their significant protein content. The cholesterol in egg yolks is a direct precursor for the production of steroid hormones, making whole eggs more valuable than egg whites alone for anyone focused on body composition and muscle development.
Nuts and nut butters (particularly almond butter and natural peanut butter) offer healthy fats alongside protein and magnesium. Be mindful of portion sizes, as the caloric density of nuts means it’s easy to consume significantly more than you realise.
The 15 Best Foods for Growing Your Glutes and Booty
With the principles established, here is a practical, evidence-backed breakdown of the most effective glute-building foods — and exactly why each one earns its place on your plate.
1. Salmon
Salmon is arguably the single most complete food for glute growth. A 150 g fillet provides around 37 g of protein alongside significant omega-3 fatty acids — a combination that simultaneously drives muscle protein synthesis and reduces the inflammation that slows recovery. Aim for two to three portions per week.
2. Chicken Breast
The most protein-dense lean meat available, chicken breast provides around 31 g of protein per 100 g with minimal fat. Its high leucine content makes it particularly effective at triggering MPS. Grill, bake, or stir-fry it with rice and vegetables for a reliable glute-building meal.
3. Eggs
One of the most nutritionally complete foods on earth. Whole eggs provide complete protein with an excellent amino acid profile, along with B vitamins, selenium, and the cholesterol your body needs to produce muscle-supporting hormones. Scrambled, boiled, or poached — keep the yolk.
4. Sweet Potato
The ideal glute-building carbohydrate. Sweet potatoes provide sustained energy for hard training sessions, potassium to support muscle contractions, and antioxidants that help reduce exercise-induced oxidative stress. Roasted sweet potato alongside a protein source is a classic combination for good reason.
5. Greek Yoghurt
Full-fat Greek yoghurt provides a dual protein source: fast-digesting whey and slow-digesting casein. This makes it particularly effective at breakfast or before bed, when sustained amino acid release supports muscle repair over an extended period. It also provides calcium, which plays a supporting role in muscle contraction.
6. Quinoa
One of the only plant foods providing all nine essential amino acids, making it invaluable for anyone following a plant-based or flexitarian diet. Quinoa also provides iron, magnesium, and a meaningful amount of fibre alongside its carbohydrate content.
7. Avocado
Rich in monounsaturated fats that support hormonal balance and anti-inflammatory pathways. Avocado is also a meaningful source of potassium — more so than bananas — which is critical for preventing muscle cramps and supporting efficient muscle contractions during your glute sessions.
8. Brown Rice
A reliable, affordable, and versatile source of complex carbohydrates that pairs well with virtually every protein source. Brown rice’s slow digestion keeps energy levels stable throughout a training session and supports glycogen replenishment in the recovery window afterwards.
9. Legumes (Chickpeas, Lentils, Black Beans)
An excellent plant-based protein and carbohydrate combination, with the added benefit of significant dietary fibre to support gut health. Pairing legumes with a grain (such as rice) provides a complete amino acid profile. Chickpeas in particular are a staple in many successful glute-building nutrition plans.
10. Cottage Cheese
Low in fat but high in casein protein, cottage cheese is one of the most effective bedtime snacks for muscle growth. Consuming casein before sleep has been shown to stimulate muscle protein synthesis throughout the night, making it a smart way to extend your body’s recovery window beyond waking hours.
11. Spinach and Dark Leafy Greens
Spinach provides iron, magnesium, and vitamin K — all of which support muscle function and energy production. Magnesium is particularly important for women who train intensely, as it plays a key role in protein synthesis and is frequently depleted through sweat. Add a handful of spinach to your post-workout meals as a matter of course.
12. Flaxseeds and Chia Seeds
Both provide plant-based omega-3 fatty acids, fibre, and a modest but meaningful protein contribution. Two tablespoons of flaxseeds provide around 4 g of plant protein alongside their anti-inflammatory omega-3 content. Stir them into your morning oats, add to smoothies, or sprinkle over yoghurt.
13. Milk and Dairy
Whole milk provides both whey and casein protein, along with calcium and vitamin D — a combination that makes it one of the most studied muscle-building beverages. Research has consistently found that fat-free or semi-skimmed milk consumed after resistance training promotes increases in lean body mass and muscle hypertrophy. For those who aren’t dairy-free, it’s an underrated and very affordable option.
14. Pumpkin Seeds
A surprisingly potent plant-based protein source at around 19 g per 100 g, alongside magnesium, zinc, and iron — micronutrients that are frequently insufficient in women’s diets and are essential for muscle repair and hormone production. A small handful as a snack or mixed into overnight oats is an easy, nutritious addition.
15. Tempeh
The most complete plant-based protein available at around 19 g per 100 g. Unlike tofu, tempeh is fermented, which improves protein digestibility and supports gut health. It’s a firm favourite in plant-based glute-building plans and is widely available in UK supermarkets and health food stores.

Meal Timing: When to Eat for Maximum Glute Growth
Once your overall daily intake is on track, the timing of your meals can give you a meaningful additional edge. Here’s how to structure your eating around training to maximise glute development.
Pre-Workout Nutrition
Aim to eat a balanced meal containing protein and carbohydrates 90 minutes to two hours before your glute session. This could be chicken and brown rice, eggs on wholegrain toast, or Greek yoghurt with oats and fruit. The goal is to arrive at your session with full glycogen stores and circulating amino acids ready to support performance and minimise muscle breakdown during the session itself.
If your schedule only allows a shorter window, a banana or piece of fruit 30–45 minutes before training provides quick-release glucose to fuel the session without weighing you down.
Post-Workout Nutrition
The post-training period is when your muscles are most receptive to protein and carbohydrates. While the idea of a narrow “anabolic window” of 30 minutes has been somewhat overstated in popular fitness culture, consuming a protein-rich meal within one to two hours of finishing your session remains genuinely beneficial for recovery and muscle protein synthesis.
A practical post-workout meal might be: salmon with sweet potato and spinach, a protein smoothie with oats and milk, or eggs and whole grain toast. The key components are 25–40 g of protein and a moderate serving of carbohydrates to replenish glycogen.
Before Bed
Your body continues to repair and build muscle during sleep — but only if it has the amino acids to do so. Consuming a slow-digesting casein protein source before bed (such as cottage cheese, full-fat Greek yoghurt, or a glass of whole milk) supports sustained muscle protein synthesis through the night. Research has shown this strategy is particularly effective at maintaining positive protein balance overnight, which compounds over weeks and months into measurable glute growth.
| Timing | What to Eat | Why |
|---|---|---|
| 1–2 hrs before training | Protein + complex carbs | Fuel the session; protect muscle from breakdown |
| Within 1–2 hrs after training | 25–40 g protein + carbs | Replenish glycogen; trigger MPS during recovery |
| Before bed | Casein protein source | Sustain overnight muscle protein synthesis |
| Throughout the day | 20–40 g protein every 3–4 hrs | Maintain positive protein balance across the day |

Do You Need to Eat More Calories to Grow Your Glutes?
This is one of the most commonly misunderstood aspects of body recomposition, and it’s particularly relevant for women looking to build their glutes. The honest answer is: it depends on where you’re starting from.
If you’re relatively new to resistance training, your body can often build muscle while simultaneously losing fat — a process known as body recomposition. In this scenario, you may not need a significant caloric surplus to see glute growth. Prioritising protein and training consistently will drive meaningful changes.
If you’re more experienced and have been training consistently for more than 12 months, you’ll likely need a modest caloric surplus — typically 200–350 calories above your maintenance intake — to continue making meaningful gains. This is small enough to minimise unnecessary fat gain while providing the energy your body needs to build new tissue.
If your primary goal is fat loss alongside glute development, a slight caloric deficit remains appropriate, but you should prioritise hitting your protein targets even more rigorously, and expect muscle growth to be slower than it would be in a surplus. Our female fat loss programme and our body recomposition programme both address this balance in detail.
For research purposes, a 2025 review confirmed that for maximum hypertrophy, weightlifters need to consume at least 44–50 kcal per kilogram of body weight daily alongside adequate protein — reinforcing that energy availability matters, not just protein intake in isolation.
Hydration: The Overlooked Element of Glute Building
Muscle tissue is approximately 75% water. Even mild dehydration — as little as 2% below optimal hydration — has been shown to reduce strength output, impair concentration, and slow recovery. If you’re arriving at your glute session even slightly dehydrated, you’re compromising the quality of every set before you’ve even begun.
The standard guidance of 2 litres (around 8 glasses) of water per day is a reasonable starting point, but women who train intensely should aim for more — particularly in the summer months or if training in a warm environment. A practical rule of thumb is to check your urine colour: pale yellow indicates good hydration, dark yellow suggests you need to drink more.
Electrolytes — particularly sodium, potassium, and magnesium — are lost through sweat and need to be replenished, especially after longer or more intense training sessions. Foods naturally rich in these minerals (avocado, sweet potato, dark leafy greens, and nuts) should feature regularly in your glute-building diet.
Foods and Habits That Undermine Glute Growth
Understanding what to eat is only half the picture. Equally important is recognising the dietary patterns that quietly undermine your progress — even when everything else appears to be in order.
Chronic under-eating is the most common obstacle for women who are working hard in the gym but seeing minimal results. If you’re consistently eating below your maintenance calories, your body will prioritise energy conservation over muscle building. The glutes — like all muscle groups — require a positive energy environment to grow.
Insufficient protein spread throughout the day is the second most common mistake. Consuming most of your daily protein in a single meal is significantly less effective for MPS than spreading it evenly across three to four meals. Research confirms that doses of 20–25 g every three hours produce the greatest increases in muscle protein synthesis rates.
Highly processed foods — takeaways, crisps, biscuits, and refined sugars — provide empty calories that displace more nutritious options without contributing meaningfully to muscle repair or recovery. They also promote systemic inflammation, which slows the recovery process your glutes depend on between sessions.
Alcohol impairs muscle protein synthesis directly, disrupts sleep quality (which is when the majority of muscle repair happens), and reduces the effectiveness of your training in the sessions following consumption. Occasional moderate drinking is unlikely to derail progress, but regular alcohol consumption is incompatible with serious glute development.
Fear of dietary fat remains prevalent in fitness culture, but as covered earlier, adequate fat intake is essential for hormonal health. Women who eat chronically low-fat diets often struggle with both mood and body composition, not because of a lack of willpower but because of genuine hormonal disruption caused by insufficient fat intake.
Supplements: What’s Actually Worth Considering
Supplements should sit at the very end of your priority list — after your overall diet, training programme, sleep, and recovery are all optimised. No supplement will compensate for poor fundamentals. That said, a small number of supplements have meaningful evidence behind them and are worth considering once those foundations are solid.
Whey protein powder is the most practical way to top up daily protein intake when food sources alone aren’t sufficient. It’s quickly digested, highly bioavailable, and rich in leucine — making it effective in the post-workout window. It’s a supplement in the most literal sense: something that supplements an otherwise solid dietary foundation.
Creatine monohydrate is one of the most extensively researched and consistently effective supplements available. A 2025 review in Nutrients found that 3–5 g of creatine monohydrate daily produced measurable increases in muscle thickness in interventions lasting 8–12 weeks. It works by increasing phosphocreatine availability in muscle tissue, allowing you to perform more volume in your training sessions — which directly translates to greater hypertrophic stimulus over time.
Vitamin D is worth monitoring, particularly for those living in the UK, where sunlight exposure is insufficient to maintain optimal levels for much of the year. Low vitamin D has been associated with reduced muscle function and impaired recovery. A standard supplement of 1,000–2,000 IU per day is broadly safe and commonly recommended by the NHS for the UK population during autumn and winter months.
Our blog on natural and herbal supplements for muscle building covers additional options in more detail for anyone interested in exploring beyond these three core recommendations.
A Sample Day of Eating for Glute Growth
The following is an example of what a well-structured glute-building nutrition day might look like for a 65 kg woman with a moderate activity level. It’s designed to hit approximately 120–130 g of protein, adequate carbohydrates, and healthy fats — without being unnecessarily restrictive or complicated.
Breakfast
3 scrambled eggs on two slices of wholegrain toast with half an avocado and a handful of spinach. Optional: a glass of semi-skimmed milk alongside.
Mid-Morning
Full-fat Greek yoghurt with mixed berries and a tablespoon of chia seeds. A banana if training later in the day.
Lunch
150 g grilled salmon with a large portion of brown rice, a serving of chickpeas, and roasted vegetables with a drizzle of olive oil.
Pre-Workout Snack (if training in the afternoon)
A banana or rice cakes with natural peanut butter consumed 45–60 minutes before training.
Post-Workout / Dinner
150 g chicken breast with a large baked sweet potato, steamed broccoli, and spinach. A glass of milk if additional protein is needed.
Before Bed
150 g cottage cheese or a small bowl of Greek yoghurt to support overnight muscle protein synthesis.
This is a framework, not a prescription. Individual needs vary significantly based on body weight, training volume, metabolism, and personal food preferences. A personalised approach — the kind we provide through our female glute & booty building programme — takes all of these variables into account.
Nutrition Without Training Won’t Build Your Glutes
