How diets work, different kinds of diets and common steps getting started.
There are several kinds of popular diets on the market today. They are all aimed at the same thing, controlling what you generally eat.
True occasional splurges aside, what you eat on average has an impact on you.
Some diets do this directly with counting and measuring. Some do this indirectly focusing more on things like habits, fullness and timing.
Can you lose or gain weight without focusing on calories? Sure. That’s what intuitive or habits-based eating focuses on.
What matters most is picking a diet that you can stick to consistently.
Today, we’re going to touch on how diets work. We'll talk about the different kinds of diets. This will help clear up any confusion you might have.
Finishing out, we'll discuss some common steps you can take to get started now.

What You Need to Know About Goals and Motivation
Nutrition and dieting are about improving our health, appearance or performance. Like strength training, most good nutrition approaches have commonalities.
When we talk about dieting, a diet is generally aimed at 3 conditions:
The nitty gritty details of calories in/calories out can be found here. (That link is super sciency)
Weight balance is all controlled by calories. How you look and feel depends on what you eat with those calories.
Every diet controls calories in some way. The math is unavoidable. Where they differ is ease and preference.
Some diets work for some people because they limit foods that are likely to be overeaten:
A diet like intermittent fasting limits calories by managing time spent eating. Those diets may work for people prone to chronic snacking.
Habit and intuitive based diets work for some people because of their ease.
You don't need a meal plan, what you need is a system flexible enough for your lifestyle.
There is no one perfect diet so, this may take some trial and error.
Let's take a deeper look into how many kinds of diets there are.
All diets generally fall into one of four broad categories.
An archetype is a model or in this case a kind of diet.
These four broad categories come from Alan Aragon, nutrition researcher and educator. Alan gave a presentation on "Toward Ending The Diet Wars: Which One is Best for Weight Loss and Health".
In the talk, Alan discussed diet types and the evidence of the literature to date.
Alan's presentation from the 2015 NSCA personal trainers conference can be found here.
There are many different kinds of diets. They all have some similar things in common that allow them to be classified as one of the following:
These are not mutually exclusive categories. Some serving and food group diets use aspects of other diets.
For example, combining timing or elimination and limitation of certain foods.
These involve a manipulation of one of the three main energy containing macronutrients. Those are carbohydrates, fats and protein.
Technically, there is a fourth macronutrient, alcohol. For the purposes of nutrition it is not digested the same way or considered essential. Essential is something you need to live.
Different kinds of Macronutrient focused diets include:
Read more about Macronutrient focused diets here.
Removing a kind of food group from your eating plan is the focus here. There are different iterations that attempt to remove or limit one of the "big 8".
The Big 8 are foods that are known allergens by FDA law;
Elimination diets (without medical reasons like allergies) can vary. Some seem to be contradictory. Known allergens are promoted counter to claims that certain other foods cause inflammation.
For example, eliminating wheat, nuts and milk while emphasizing fish consumption (paleo).
Remember, if you've gotten results on paleo, I'm not telling you not to stick to it. (don't @ me, bro)
These diets consider when and how often you eat meals. There may be times of eating and fasting. There may also be aspects of eating certain kinds of foods at different times.
An example of this is timing carbohydrates and protein around activity. Athletes and weight lifters often use this strategy.
Another iteration is a mix between many, small meals or larger, less frequent meals.
Diets in this category are considered the least controversial. According to Alan, these represent a "semi-current state of the evidence". The MyPlate program, is the United States Department of Agriculture's example of this.
Other serving and food focused diets include;
I would also consider a habits based diet to fall under this category.
When clients approach me, I generally recommend one of two approaches to eating.
In either case, I would still recommend that you try your hand and meal prepping.
Meal prepping is a form of choice architecture. Choice architecture is setting up situations to make good choices easier. (Keeping Oreos out of my pantry for example).
People commonly use choice architecture strategies to help keep themselves on track.
Examples I've mentioned that are choice architecture:
For a deep dive on choice architecture, I recommend you get a copy of Nudge: Improving Decisions about Health, Wealth, and Happiness. In Nudge, Richard Thaler and Cass Sunstein detail how you can improve choice.
Thaler is credited with inventing this field, known as behavioural economics. He won a Nobel in Economics in 2017.
The foundations for controlling what you eat can make a couple assumptions:
Habits based nutrition has more of a focus on what you do around the foods you eat.
Are you distracted?
That might mean:
Situations like these influence people to eat more food than they normally would.
Ways you can combat these things include:
Habits based diets are generally easier to start. There's a focus on action and simplicity.
If you've never dieted before, a couple small changes can have large results.
One example of this is a client that I got to focus on protein at every meal.
That one switch has changed her life in several ways:
Once you set your goal, the focus shifts to the exact things you can do to reach it.
With the right platform, a habits approach can be highly informative.
Things can be scaled to the level you’re at now.
If you’re already eating healthy foods, dialing in on some of the basics can still be a change. The results you get from the little things will just be smaller.
The major drawback of a habits-based system is typical in it’s accuracy.
Common portions mentioned in habits based systems per meal are:
I played some college football so, I’m larger than normal. Eating “2 palms of protein” for me is a ridiculous amount of chicken.
I much prefer to weigh my chicken portions 5-5.5oz of cooked meat.
Measuring helps me be a little more scientific and feel a sense of comfort and control.
Protein helps build lean muscle.
Carbohydrates fuel your exercise.
Fiber helps keep you full.
Fats help regulate hormones.
Sprinkled in spices and washed down with water.
A macronutrients approach is generally a next step for someone already eating healthy.
This system can work for someone who changes the foods they eat semi-regularly. When you go out to eat, you can adjust what you’re eating based on what is available.
Think of the numbers more as guardrails. There is a large degree of flexibility.
Ex. Try to eat around this amount of calories (a) hitting, (b) amount of protein, (c) carbs and (d) grams of fat.
If you need to make tweaks to gain, lose, and maintain weight, they're fairly simple. You can add calories here and there and watch your scale to see if they're working.
The major drawback of a macronutrient focused diet also ironically revolves around accuracy
When you go out to eat, most restaurants won't list macros. If you tend to have an obsessive personality, it can be difficult to put the numbers aside for a meal.
This approach can also seem very daunting to someone who hasn't dieted before.
There are a lot of numbers and small details available to track.
Ex. 50 grams of protein is:
Ex. 50 grams of Carbohydrates:
Carbs can vary greatly per serving
Ex. 15 grams of fat
Of course you need to consider ALL the macronutrients in each food.
If you didn’t learn to lift in high school or it’s been a while, a weight room looks like a maze of weights, switches, knobs and bros.
Do more than just go pick up a dumbell; let’s create a plan to build strength, get sustainable results (and look like you know what you’re doing).
We’ll start with the basics of strength training and you’ll walk out with (a starter amount of) confidence.
