With all the information available in the internet, fit teas, shady supplements and all the scammy programs out there, you are confused about losing weight and most importantly losing body fat. The fact is losing weight or fat needs a scientific approach, since calories are energy and we consume energy in the form of calories.

Losing weight fundamentals

We’ve all been there do not worry, thanks to the modern diet trends, products that promise unreal results, misleading supplements, misleading good genetics trainers and others we are left with some kind of true information and some not so true. As an individual that has lost weight and maintained it and see this works for everyone i am telling you it is simpler than you think but it is by no means easy.

People may say you need to cut out carbs, this is not true

People will say you eat too much fat, also not true

The reality is, you just eat too much. That’s the real cause of weight gain, you can eat carbs and fats to stay in shape and it is actually the right thing to do. But fitness myths are just crazy. Here is the science behind it.

If you eat more calories than you burn in the day you will gain weight.

If you eat less calories than you burn in the day you will lose weight.

YES! Forget all the bro-nonsense that wants you to believe that carbs, sugar, insulin, artificial sweeteners, mixing carbs and fat, eating at night, eating after 6 pm. All of this is complete NONSENSE.  The key to body composition is energy balance and it is scientifically proven.

But but but…. i cut carbs and i lost 5 lbs in a week. Well yeah, its called losing water and glycogen weight and all of this weight isn’t fat, even if you are in the caloric deficit, not eating carbs is not sustainable and not healthy at all which will cause you to regain your weight in no time!

The reason why cutting carbs or fats works its because it reduces your overall caloric intake. And that is the main reason for weight loss. That’s why you see people eating fast food and losing weight in social media. Because they stay in a caloric deficit. This is also known as flexible dieting.

Are you what you eat?

Well no, but yes, let me explain this. I’m sure you’ve seen seen, eat crap and you will feel like crap, you are what you eat and a lot more. The reality is that your diet can suck and you can still have a good body, this is due to the science of energy balance. Let me give you an example;

John maintains 11% body fat with 2400 calories per day, he decides he’s only eating fast food but maintaining his 2400 calories. His physique will look the same due to his calorie needs, assuming he has a right ratio of macronutrients.

With that being said, he will likely have micro nutrient deficiencies which can impact his performance in the gym and a lot of aspects of his health.

What i’m trying to state here is that you should have a well balanced diet, rich in fruits, vegetables, legumes and healthy fats. But you can occasionally eat fast food,pizza or ice cream and still be in great shape thanks to science (yey!). So you shouldn’t eat clean 24/7 which hopefully is a relief.

Macronutrients: also important for body composition.

“This fits my macros brah”. Macro nutrients are an essential part of dieting. If we want to make a diet work we need to understand the concept of macro nutrients. There are 3 macronutrients. Proteins, Carbohydrates, and Fats or Lipids.  Carbohydrates and fats have a bad reputation due to mainstream media advice, claiming that this is the cause of your weight gain. Let me say that no macronutrient is responsible for gaining weight, but as we stated earlier, overeating the amount of calories you burn per day is the real responsible.

Here are the calories per gram of Macronutrient;

Proteins: 4 cal/ gram

Carbohydrates: 4 cal/gram

Fats/Lipids: 9 cal/gram

1 gram of fat has a little bit over the double of calories than protein or carbohydrates, however fats are essential for our body’s hormonal function and other vital functions.

Protein is important because they’re the building blocks of muscle tissue.

Carbohydrates are important because they’re the main fuel of your body.

Fats are important to maintain optimal hormonal functions.

So what are the optimal macronutrients to lose weight?

Well it is different to lose weight and to lose fat. If you want to lose weight you will simply need to cut your overall calories, however if you want to lose fat  you need to emphasize certain macronutrients.

This is a recommended macronutrient distribution in percentages:

30% Protein

30% Fat

40% Carbohydrates

Since protein recommendations are about 1 gram per pound of bw this how it would look if you choose to manage your nutrition in grams;

1 gram of protein per Lb of BW.

20-30% of Fats

Fill in the rest of calories with carbs.

 

Here is an example for a 180 lb male:

Lets find the mainiment calories and subtract a 20% calorie deficit that should allow this person to lose about 1 -2 lbs per week ( which is optimal).

180*16=2880 – 20% = 2304 calories per day to lose weight.

180 grams of protein (1 gram per pound)

76.8 grams of fat (30% of total daily caloric intake)

222.2 grams of carbs ( the rest of the calories available)

These are the calories and macronutrients that would be ideal to lose fat. In the case of only wanting to lose weight, he can stick to the 2304 daily calories.

That’s how you really lose weight, you can incorporate different strategies like intermittent fasting to make this more enjoyable. Make sure the 80% of your food comes from healthy food at least the majority of the time.

If your weight loss stucks, decrease another 10% of that caloric deficit, make sure you weight yourself in the same situations everyday to make sure it is as accurate as possible. I like as soon as i wake up and use the restroom.

These are the fundamentals of losing weight!
