The FAQ is to keep you honest and focused.

Let’s get into the real way to lose weight–and feel good while doing it.

Step 1: The Mindset Shift That Made It Possible

Before I even picked up a salad or tied up my running shoes, I made one important mindset shift: I stopped looking at the number and started looking at the process.

I started asking myself:

“What would the healthiest version of me do today?”

“How would someone who has already lost 20 pounds eat, move, and think?”

This mindset was helpful because it kept me looking at my daily actions and not the scale. I visualized the final result every morning, and even spent 5 minutes journaling how I wanted to feel.

Affirmations I Said to Myself Every Day

“I’m committed, not interested.”

“Progress over perfection.”

“It’s feeling healthy, feels better than junk food taste.”

Step 2: The Diet I Followed to Lose 20 Pounds (without starving)

Let’s be honest—diet accounts for about 80% of weight loss. Though you don’t need a crash diet, nor do you need to cut out carbs. You need balance, structure, with accountability.

So here’s what my eating habits looked like:

My Daily Caloric Goal:

I aimed for a 500 – 700-calorie deficit each day, which should equal about 1 – 1.5 pounds of fat loss per week.

My average intake: 1,500 – 1,700 Calories/day, depending on the intensity of my workouts.

Weekly Meal Plan Recipe:

Meal: Examples

Breakfast: Greek yogurt + berries + chia seeds

Or scrambled eggs + avocado toast

Lunch: Grilled chicken salad with olive oil vinaigrette

                       Or brown rice + stir-fried veggies + tofu

Snack : Almonds + apple

Or protein shake

Dinner: Salmon + roasted sweet potatoes + broccoli

Or turkey chili with mixed greens

Dessert (Optional)         85% dark chocolate (1-2 squares) or protein pudding

I focused on:

High protein intake (100 g+ per day)

Carbs with fiber (sweet potato, oats, berries)

Healthy fats (olive oil, avocado, nuts)

Hydration (3L water/day)

I focused on:

High protein intake (100 g+ per day)

Carbs with fiber (sweet potato, oats, berries)

Healthy fats (olive oil, avocado, nuts)

Hydration (3L water/day)

Foods I Decided to Limit:

Processed sugar

Soda & alcohol

Fried foods

Late-night snacking

But I didn’t restrict anything—I allowed one “free meal” a week to enjoy pizza, pasta or dessert without guilt.

Step 3: My Exercise Plan – Burn Fat, Build Muscle

I didn’t run on a treadmill for hours; I did an intelligent balance of strength training, cardio, and mobility, which allowed me to burn fat while preserving lean muscle tissue – this is essential for long-term sustainable weight loss.

Weekly Exercise Routine:

Day.                      Exercise

Monday         45 min strength training (upper body)

Tuesday.       30 min HIIT + 15 min cool walking

Wednesday   45 min strength (lower body) + stretching

Thursday       Active recovery (walking, yoga or light cycling)

Friday, 45 min full body strength circuit

Saturday, 1 hour hike or dance

Sunday           Rest or light stretching

My Go-To, Fat-Burning 30-Min HIIT Circuit:

30 seconds of each:

Jump squats

Mountain climbers (be careful if you have bad knees)

Push-ups (try box push-ups if these are too hard)

Burpees (modify to your ability)

High knees

1-minute rest

Repeat 5 rounds

This workout built a calorie deficit and made my metabolism hum along for hours.

Don’t Forget NEAT:

NEAT = Non-Exercise Activity Thermogenesis (calories you burn outside of a workout).

I added simple habits:

– 10K steps/day (tracked via smart watch)

– took the stairs instead of the elevator

– light stretching while watching TV

Step 4: Mindset, Motivation & Accountability

The cold, hard truth is that motivation is fleeting. Systems are not. It’s how I built small systems to keep me moving on the tough days.

My Weekly Tracking System:

Weigh every Sunday morning

Tracked all food through MyFitnessPal

Journalled how I felt after meals (to stay aware)

Took progress photos every 2 weeks (SUPER motivating!)

My Accountability Systems:

Joined a fitness community on WhatsApp

Followed fitness creators on IG and TikTok

Built a playlist of motivational songs for working out

Step 5: Sleep, Stress & Self-Care

Weight loss was never just about food and exercise, but it was also about recovery and mental well-being.

I Made Sleep a Priority:

7 – 9 hours of sleep/night

Screens off 1 hour prior to bed.

Took magnesium supplements + herbal tea

For Stress Relief:

Meditated for 10 minutes using the Headspace app

Walked in the evening after dinner to recharge.

Set boundaries (I said NO even more!)

What to Do When You Have a Plateau

Weight loss plateaus happen to the best of us. Here’s how I busted through mine:

Switched up workouts every 3-4 weeks

Lowered portion sizes slightly (by ~100 – 150 calories per day)

Added 15-minute morning walks

Checked for any hidden calories (sauces, dressings, snacks)

Increased water intake to reduce bloat.

Actual Outcomes: My 3-Month Change

Mont Pounds Lost         NSVs (Non-Scale Victories)

Month 1 -7 lbs. Jeans fit better, and More energy

Month 2 -6 lbs, Clearer skin, Sleep improved

Month 3 -7 lbs         QMaybe I have abs?, Comfortable selfies!

Total lost: 20 lbs in 12 weeks

But more than that, I gained:

Confidence in my body

Trust in my habits

A sustainable lifestyle I can keep for life

 Final Thoughts: Is It Worth It?

Absolutely—this is perfectly clear, and what’s better is it’s not just because of the weight I lost.

This journey made me stronger mentally, emotionally, and physically. It taught me discipline, self-love, and that consistency is greater than motivation.

FAQs

Is it possible to lose 20 pounds without exercising?

Technically, yes, but diet + exercise allows for better health, muscle retention, and overall results.

Only 10 pounds in three months. Is that okay?

That’s great progress. Everybody’s body is different. Look at fat loss, inches lost, energy gained too—not just the number on the scale.

What diet did you use to achieve your goals?

The best diet is the one you can follow, such as Mediterranean, high protein, or portion-controlled. Fad diets and extremes are what I don’t recommend.

Did you use any supplements?

I only used whey protein and magnesium before bed. I did not take fat burners or use any gimmicks.

How did you manage cravings?

I let myself have some tiny treats or replace cravings with high-protein snacks. The more consistent I was, the less I craved junk food.
