It's not simply about the quantity of macros.
It's the beginning of a new year, and if you're like most people, you're searching for ways to incorporate healthy habits into your daily routine. You may even be considering a low carb diet. You've seen people lose weight with it, so you have "proof" that it works.
Low carb diets range from keto to paleo (while paleo isn't always promoted as low carb, it excludes whole grains and legumes, which contain more carbs).
Is low carb the way to go?
According to a recent study published on December 27, 2023, in JAMA Network Open, maybe. However, if you want excellent results, you should verify the quality of your macros—because merely lowering carbohydrates does not guarantee the desired benefits, especially over time.
How Was the Study Conducted?
For this investigation, researchers examined data from three extensive cohort studies: the Nurses' Health Study, the Nurses' Health Study II, and the Health Professionals Follow-up Study. They looked at five distinct indicators related to low carb diets:
- A low carb diet that emphasizes overall decreased carb consumption.
- An animal-based low carb diet centered on animal-sourced protein and fat.
- A vegetable-based, low carb diet with an emphasis on plant-based protein and fat
- Healthy low carb diet with emphasis on less processed carbohydrates, more plant protein, and healthy fats.
- Bad low carb diet with an emphasis on processed carbohydrates, animal proteins, and unhealthy fats.
Males and girls of many races and ethnicities participated, including African Americans, Asians, Hispanics, non-Hispanic whites, and the unknown. The research comprised 123,332 individuals with an average age of 45.
Because the cohorts under study were from long-term studies, researchers could examine nutrition and weight increase across four years.
What Did the Study Show?
After adjusting for other lifestyle characteristics, the researchers examined each group's meal composition, BMI, and weight increase during a four-year cycle.
They discovered that a high-quality, low carb diet rich in plant-based proteins and healthy fats was related to slower weight gain than a lower-quality diet heavy in animal-based proteins and fat (hello, keto).
As a result, the researchers argue that while aiming to maintain a healthy weight, it is essential to consider not only the ratio of macronutrients (carbs, protein, and fat) but also their quality.
Why Does This Matter?
Consider the long term when looking for an eating pattern that works for you. What eating approach can you take in the long run? What meals are beneficial for your body? Do you have the energy to go through the day and perform at your best?
The answers to these questions will be unique to each individual.
Eating more vegetables, good fats, and whole grains allows us to live longer. These meals are all high-quality.
If eating fewer carbohydrates makes you feel better, ensure you get high-quality carbohydrates. This includes high-quality plant protein from veggies, legumes, nuts, seeds, and healthy fats such as avocados and olive oil.
If you need meat, eggs, and dairy to be satiated, that's OK. It's all about balance, which involves other lifestyle choices besides food, physical exercise, stress management, and obtaining enough sleep, impacting overall health and quality of life.
The Bottom Line
Include a variety of high-quality meals in your diet and determine the macronutrient ratio that works best for you. Complete this with regular physical exercise, low stress, and quality sleep. And expand your social network. According to research, having solid social relationships might help avoid cognitive declines such as dementia and depression.
