How to lose weight
Losing weight is simple, but it’s not easy.
It’s gonna take work, it’s gonna take time and patience, but if you stay
consistent, you will see results.
Are you willing to put in the time?
Are you willing to be patient?
Are you willing to make mistakes and learn from them?
Weight loss is not an overnight process.
There are no magic fat burning pills that will shed your belly fat overnight,
nor is there a quick and easy solution.
Weight loss takes months of consistent dieting and training.
With that all said, I present to you: how to lose weight- science
explained.
Key takeaways
1. Weight loss is achieved by consistently being in a caloric deficit i.e.
eating fewer calories than you burn.
2. To lose fat and not muscle you need to eat a high protein diet and
engage in resistance training.
3. Cardio is not necessary for weight loss but can be useful.
The “secret” to weight loss
Your body burns a certain amount of energy(expressed in calories) every
day to function properly.
This is called your TDEE(Total Daily Energy Expenditure).
Your TDEE is the amount of calories you need to eat to maintain your body
weight.
Now, what happens when you eat more calories than you need?
That extra energy can’t just evaporate, it needs to go somewhere and that
somewhere is usually your fat stores(and sometimes muscle but we’ll get to
that in a second).
But what would happen if you eat fewer calories than your TDEE?
Your body needs to get that energy from somewhere, and that somewhere
is, you guessed it, your fat stores and unfortunately, your muscles.
This has been proven, time and time again, to be the main factor that
controls your weight: calories in vs calories out.
While it does have some more complex workings behind it, it still stands as
the definitive explanation.
So there’s the jist of it: eat fewer calories than you burn and you will lose
weight.
Problem is, you shouldn’t be trying to lose weight but actually to lose fat.
Why you should focus on losing fat, and not
weight
Here’s a “little” problem with caloric deficits: the weight you lose will not
exclusively come from fat, but also from water and more importantly,
muscle.
When people embark on crash diets(where you drastically reduce your
food intake to lose weight quickly) what they’ll find is they’ve lost a ton of
weight, but they’ve also lost huge amounts of muscle.
What you wind up with on these diets is the “skinny fat” physique.
To prevent this, you should take additional measures to prevent muscle
loss and lose fat relatively quickly but safely:
Engage in a moderate caloric deficit
My recommendation: 20-25% less than your TDEE.
For a man who burns 2000 calories, he would eat about -
calories to lose fat.
Why this number?
In my experience, this a sweet spot for most people.
Can you go lower? Surprisingly, yeah.
A study in 2012 put men in a 40% caloric deficit with a high protein intake,
and they still preserved muscle and lost a ton of fat.
Should you go lower?
Bear in mind how little you would be eating with this deficit.
A 40% deficit for a regular guy who burns 2000 calories would have him eat
1200 calories a day, and you would need to get most of those calories from
protein to preserve muscle.
If you think you have the willpower to maintain this, go ahead.
But remember, your diet should work for you, not against you.
Starving yourself will just drain you psychologically and increase the
chances of you bingeing on junk food.
How do I calculate my TDEE?
There are a ton of ways to calculate your caloric burn, and none of them
are accurate.
They don’t take into account a load of factors, like different metabolisms,
activity levels etc..
The only way to accurately gauge how many calories you burn is this
1. Use any method to estimate your TDEE. I like the Katch-Mccardle
equation, since it takes into account your bodyfat.
If you can’t accurately estimate your bodyfat, use this formula:
Your bodyweightX14-17
Pick the lower end of that range if you’re less active.
Pick the higher end if you’re more active.
2. Eat this amount of calories for a week.
If you lose weight, you need to eat more.
If you gain weight, you need to eat less.
Keep adjusting until your weight remains stable.
Eat a high protein diet and adjust your fat and carb
intake based on preference.
Protein is one of the three main macronutrients, it’s what our skin, bones,
nails are made of, and eating enough of it is crucial for muscle growth.
Study after study has shown, a high protein diet is essential for building
muscle and extremely useful for losing fat.
It is the most satiating macronutrient, which comes in handy when you’re
dieting.
Not only that, protein is highly thermogenic.
Thermogenic means you burn a relatively high amount of calories to digest
it.
For example, if you eat 800 calories worth of protein, 160 to 280 of those
calories will be burned to digest that protein(the thermic effect of protein is
20 to 35%).
How much protein?
While the amount needed for muscle growth is lower than what most
people think, I still recommend 1 gram of protein per pound of
bodyweight(2.2g per kg of bodyweight).
Why? Well, just for safe measure.
Some people have been shown in the literature to need a higher protein
diet than other people to maintain muscle.
This recommendation should cover most people’s needs but you can still
start from the lower end which is 0.8g per pound and adjust based on your
results.
Engage in resistance training at least 2x a week.
There’s no doubt about it: to preserve muscle(and enhance fat loss) you
need to do some form of resistance training.
Not only will you build muscle, you will also
● Boost your metabolism
● Burn extra calories
● Increase your energy levels
You’re also not limited only to the gym.
You can build muscle with bodyweight training as well.
Resistance is resistance, whether it comes from lifting weights or lifting
yourself up on a pull up bar.
But the main point is: some form of resistance training is extremely
beneficial for fat loss, and you should take care to learn how to build
muscle.
Limit your cardio.
Yes, you’ve heard me right. LIMIT your cardio.
While I recommend everyone to do some form of cardio to improve and
maintain cardiovascular health, it is not necessary for fat loss and can be
detrimental to muscle growth if done too much.
Cardio produces something called t he interference effect, which, you’ve
guessed it, interferes with muscle growth.
And no, it does not have any special fat burning effects, such as the
popular “fat burning zone” myth.
