These are the only things you need to worry about for fat loss:
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
- Calorie deficit.
- Protein intake.
- Resistance training.
- Recovery.
- Micronutrients.
- Movement.
Everything else is either a scam or will only move the needle a tiny amount. -
β Calorie Deficitβ
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
If you're not in one, nothing's going to happen.
You can avoid all the fad diets that make you feel like crap and just focus on foods that:
β Are filling
β Are lower calorie
β You enjoy eating
β Are high in protein (more on that later) -
I like to track my calories accurately when losing fat.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
It's a must for me as I want to occasionally eat things like a bar of chocolate or have an ice cream with my kids.
Why unnecessarily eliminate these things when you can keep them in and still lose fat? -
You want a MANAGEABLE calorie deficit.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
If you try to push too hard you'll be low on energy and you're increasing the risk of losing muscle and having binges. -
Without doubt, the best approach is to use macrofactor for your initial food targets, then use it to log your food and weight.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
It'll adjust your targets based on your progress to have you losing weight at the right rate and on track for your goal.https://t.co/YxtU15vUQy -
It's WAY better than other calorie tracking apps.

β Protein intake β
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
You want a high protein intake.
This has several benefits:
- Maintain muscle
- Be satiated (feel full)
- Burn more calories through digestion
1.6g per KG of your bodyweight is my recommended intake that will be enough to maintain muscle (0.73g per lb) -
There's no need to eat 1g per lb of your body weight, especially if you're overweight.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
No one needs to eat 350g of protein. You'll probably eat more calories than necessary if you do this. -
Most studies on the subject find there's no benefit beyond an intake of 1.6g per KG/0.73g per lb.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
So just shoot for that.
But if you eat more, that's fine too.
Protein requires about 30% more calories to digest than other foods so it will help for fat loss. -
β Resistance Training β
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
You need to be resistance training if you want to maintain muscle as you lose fat.
You SHOULD want to maintain (or build) muscle while you lose fat.
Improving your lean body mass as a % of your overall weight will totally transform the way you look. -
I've had periods in my life when I squeezed workouts into my lunch hour & got it done in 20-30 minutes.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
Sometimes doing just ONE set per workout.
One set per muscle group per week is fine if you work hard enough (very close to failure). -
But if you have time, pick 2 compound exercises per session, and do 3 sets of each RPT(reverse pyramid training) style.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023 -
Good compound exercises to focus on are:
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
- Incline bench
- T-bar row
- Seated dumbbell press
- Dumbbell one arm row
- Incline DB press
- Seated Row
- Barbell back squat
- Romanian Deadlifts
- Reverse luges
- Bulgarian Split Squats
- Hip thrusts -
First set heavy, 4-6 or 6-8 reps (depending on nature of the exercise), go 1 rep from absolute failure.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
Drop weight 10% for next 2 sets and go to almost failure again.
No isolation work whatsoever. -
You could spread this across 4-5 sessions per week of no more than 30 minutes each.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
You could also do it across 2 or 3 longer sessions and it wouldn't make much difference. -
β Recovery β
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
When you're in a calorie deficit, recovery is already harder - so keep workouts short.
Sleep 7+ hours a night, quality unbroken sleep if possible.
If your sleep is of poor quality you will find it harder to stick to your diet and recover from your workouts. -
β Micronutrients β
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
At least 80% of your diet should be from quality food that contains a lot of vitamins and minerals.
Eat eggs, beef, fish, lamb, vegetables (most veg - not root veg - is ideal for loading onto your plate as it is very filling for basically no calories). -
Recovery and training is going to be worse if you eat crap food.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
You also won't get to eat as much food or burn as many calories through digestion.
Highly processed food is usually more calorie dense, so it provides more energy for how much it fills you up. -
Whole foods have a higher thermic effect than processed foods.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
Meaning you burn more calories through digestion from eating whole foods than you would from the same calories from processed foods. -
Lastly on micronutrients, I would say it's worth supplementing some:
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
- Magnesium
- Omega 3
- Vitamin D (if you don't see much sun)
These won't affect fat loss but they will have other benefits for health. -
β Movement β
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
Forget traditional cardio.
It works to burn calories but it's unnecessary.
Just get out and walk. If you don't do 10,000 steps a day, start. Anyone can do this.
If you already do 10,000 steps a day, try and do more. -
Remember, it's not about single days.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
It's about averages.
Sometimes during a fat loss phase I have days where I eat too much junk and days where I skip workouts.
Don't look at these days in isolation. Look at your average across lots of days. -
If you average 80-90% on track over a long period like 3 months then you'll see results
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023 -
β Bonus - Diet Breaks! β
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
Don't spend too long in a calorie deficit.
Toughing it out in a calorie deficit for several months in a row will take its toll (both mentally and physically). -
You'll also move less and expend less energy subconsciously.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
You'll get lazier and expend less energy through unconscious movement (like tapping your foot, or waving your arms when you speak) -
To combat all of this, take a diet break AT LEAST every 3 months.
— Rob - Nothing Barred Fitness (@Rob_NBF) March 13, 2023
A good guide is to take a one week diet break for each month you've been in a calorie deficit, and ideally this is at least every 3 months.
Just up calories to maintenance for a week. -
