Part 2 · The Plan

You can't grow a peach on air. What to eat, the exact 4-week glute split I'd give you, and how to stay patient while your body changes.

Before we start

Hey bestie,
I was you.

A few years ago I had no idea what I was doing. I just knew I wanted to change my body, and I wasn't happy with how I looked.

So I did what everyone on social media seemed to do. Loads of cardio. Copying random workouts. Tracking every calorie and eating as little as possible, because I genuinely believed that was the key.

I lost weight fast. And I felt worse than ever. I was "skinny fat": smaller, but with no shape and no energy. I trained on an empty stomach, slept badly and lived in an all-or-nothing loop: five days of barely eating, then one sweet thing and I'd go completely off the rails.

The craziest part? My glutes didn't grow. At all. No matter how hard I trained.

Everything changed when I learned that I had to eat more to build muscle. Scary at first. But my body got stronger, my shape changed, and my confidence finally followed.

This guide is everything I wish someone had told me back then. No extreme diets, no endless cardio. Just what actually works.

Let's build it. Jas

You can't grow
a peach on air

Protein, calories, carbs, recovery, and why eating enough was the turning point in my own journey: from trying to be smaller to becoming stronger.

01 · You can't grow a peach on air

Smaller vs. stronger

For years my only goal was to be as small as possible. People told me I looked good, so I kept eating less. But inside I felt awful, and my glutes just wouldn't grow.

Then I read that you need to eat more to build muscle. Honestly? That scared me. But I tried it. The scale went up a little, then stayed stable, while my body got stronger and my shape changed. That's when I understood: muscle is what gives you shape, and muscle needs food.

The second eye-opener: it's your weekly average that counts, not one day. A pizza with your friends isn't the end of the world. Log it, enjoy it, move on.

Are you under-eating?
  • Your lifts haven't gone up in weeks
  • You're always tired or cold
  • You sleep badly or wake up hungry
  • You crave sugar like crazy at night
  • Strict weekdays, out-of-control weekends
  • You train hard but look "flat"

Two or more ticks? Your body is asking for more fuel.

Step 1: your calories

To grow glutes you want to eat at maintenance (the amount that keeps your weight stable) or a small surplus of around 150 to 300 kcal on top of that. Not a "dirty bulk". Just enough to build.

Your goal right nowCaloriesExpect
Grow glutes, gain some muscleMaintenance + 150-300 kcalSlow, steady weight gain (about 0.25-0.5 kg per month)
Reshape (build + lose some fat)Around maintenanceStable weight, changing shape
Lose fat, keep your glutesSmall deficit (-300 to -500 kcal)Keep lifting heavy and protein high

Quick start: track what you eat normally for 2 weeks while weighing yourself every morning. If your weekly average weight stays the same, that's your maintenance. And please: never 1200 calories while trying to build.

Step 2: protein, the building blocks

Aim for 1.6 to 2.2 grams of protein per kg of bodyweight per day, spread over 3 to 5 meals (about 25 to 40 g each).

Bodyweight55 kg60 kg65 kg70 kg75 kg
Protein per day90-120 g95-130 g105-145 g110-155 g120-165 g

Step 3: carbs are your friend

Carbs fuel heavy training. Cutting them means weaker sessions and less growth. Have a carb-rich meal 1 to 3 hours before you train: rice, oats, potatoes, bread, fruit.

Step 4: don't fear fats

Healthy fats support your hormones. Think eggs, avocado, nuts, olive oil, salmon. Roughly a quarter to a third of your calories.

Easy protein wins

  • Greek yoghurt or skyr with fruit and granola
  • Eggs + egg whites on toast
  • Chicken, turkey, lean beef, salmon, tofu
  • Cottage cheese (trust me, try it)
  • A protein shake after training
  • Protein pudding or quark as a dessert

A day of eating for glute growth

Example for a 60 kg woman, about 2,100 kcal and 130 g protein. Adjust portions to your own numbers.

MealWhatProtein
BreakfastOvernight oats: oats, skyr, protein powder, berries, peanut butter35 g
LunchWrap with chicken, hummus, veggies + a piece of fruit35 g
Pre-workoutRice cakes with banana and honey3 g
DinnerSalmon or tofu, rice, roasted veggies, olive oil35 g
EveningQuark or protein pudding with a little chocolate22 g

Step 5: recovery = growth

Sleep 7-9 h

Your most underrated glute supplement.

Rest days

At least 1 day between hard glute sessions.

Daily steps

7,000 to 10,000 steps keeps you active without killing recovery.

Day B · Tue

Upper body

Back, shoulders and arms for that balanced shape.

Single leg + lengthened focus. Deep and controlled.

Day D · Sat

Full peach

Glute medius, unilateral thrusts and back extensions.

After week 4: take one lighter week (half the sets, same weights), then run the plan again starting from your new numbers. Take progress photos on day 1 and at the end of every 4 weeks: same spot, same light, same time of day.

Chapter 03

Patience makes
the peach

Managing weight gain, body-image changes, comparison and unrealistic social-media expectations, while learning to trust the process and stay consistent.

The scale will go up. That's okay.

When you eat more and train harder, your weight will likely rise a little. Part of it is muscle, part is more food, water and glycogen in your muscles. That's not fat, that's fuel. Watch your weekly average, your lifts, and how your jeans fit.

Comparison is a thief

That girl on your feed? Good lighting, perfect angle, years of training, and genetics you don't share. When someone tells me "I want to look like you", I mostly think about how hard the road behind it was. Compare yourself to you, 4 weeks ago.

Progress isn't a straight line

Some weeks you'll feel amazing, some weeks bloated and flat. A missed session or a big weekend doesn't erase anything. Just get back to your next planned workout. No "starting again on Monday".

What to realistically expect

Week 1-4

Stronger lifts, better mind-muscle connection, more energy.

Month 2-3

Your clothes start fitting differently. Leggings sit better.

Month 3-6

Visible shape changes in photos. Others start noticing.

Month 6-12+

The real transformation. This is where consistency pays off.

Strong, healthy and happy is worth so much more than being thin.
