High-Protein Breakfast, Exercise Intensity, & Effects of Tech at Night
Hello, Wonderful Readers!
Today, we delve into the power of high-protein breakfasts π³, examine exercise intensity impacts πββοΈ, and probe into bedtime tech use effects π±π€.
Expect clear insights, useful takeaways, and actionable steps. Let's jump right in! π
1st Study
Let's dive into breakfast π₯! You know it's key, right? But many of us are breakfast skippers π. Well, according to a 2015 study, our breakfast habits can be real weight and hunger game-changers! PMID: 26239831
Here's the tea β: The study split breakfast skippers into three groups.
Group 1 continued skipping breakfast π«π³.
Group 2 had a normal protein breakfast π₯£ (13g of protein, about 350 calories).
Group 3 ate a high-protein breakfast π³π₯ (35g protein, around 350 calories too).
And the results? The high-protein breakfast group were the champions π!

The normal protein breakfast group? Not so much. Their body fat and daily intake remained the same, and hunger levels didn't drop.
Main takeaway π―: High-protein breakfasts (35g protein, around 350 calories) can potentially prevent weight gain, reduce daily calorie intake by about 412 calories, and decrease hunger.
Actionable step πͺ: Instead of skipping breakfast or grabbing a carb-loaded snack, try to pile on more protein. Go for scrambled eggs, Greek yoghurt with fruit, or a protein shake. Test this out for a few weeks - your scale might surprise you with a loss of a pound or so π!
2nd Study
Exercise Talk πͺπββοΈ: High-Intensity Interval Training (HIIT) or Moderate-Intensity Continuous Training (MICT)? Which is better for insulin sensitivity?
This 2020 study sought to answer that by recruiting 31 inactive adults with obesity to follow a 12-week HIIT or MICT program. PMID: 32492705)
HIIT entailed 10 sets of 1-minute workouts at 90% max heart rate, while MICT involved a 45-minute workout at 70% max heart rate.
The surprising result? Both groups saw similar benefits! π

Meanwhile, their body weight and fat mass remained constant. The only hiccup? If they stopped exercising for 4 days, their insulin sensitivity returned to pre-training levels.
Main takeaway π―: Whether you're a fan of the HIIT or MICT approach, both can boost insulin sensitivity by roughly 20% the day after exercising. Keep in mind, though, a four-day break might roll back these benefits.
Actionable step πͺ: Choose your workout style - do you prefer shorter, intense workouts (HIIT) or longer, moderate ones (MICT)?
Schedule at least 3 sessions per week and stick to them! Consistency is vital for maintaining those insulin sensitivity improvements.
3rd Study
Are you wondering how nighttime tech usage could affect not just your children, but you as well? π±πΉοΈπΊ A 2017 study offers some insightful findings, especially concerning sleep quality and BMI! PMID: 29119131
The research looked at 207 surveys from parents of children aged 8-17. Here are the significant results:
1οΈβ£ Sleep and Tech Use: Children who watched TV or used their phones at bedtime lost approximately 30 minutes to an hour of sleep π΄. It was the same for video game and computer users, with each losing around an hour of sleep π».

2οΈβ£ Tech Use and BMI: Children who watched TV or used phones at bedtime were 2.4 and 2.3 times respectively more likely to be overweight or obese π.

3οΈβ£ Tech Use and Breakfast: Children who used their phone, video games, or a computer at bedtime were 70%, 70%, and 60% respectively less likely to have breakfast in the morning π₯.

4οΈβ£ Morning Tiredness and Tech Use: Children who used their phone, video games, or a computer at bedtime were 2.5, 2.2, and 2.6 times respectively more likely to be tired in the morning π .

Those who watched TV at bedtime had a lesser, but still present increased likelihood of morning tiredness (1.4 times) πͺ.
Main takeaway π―: Using tech at night might lead to less sleep (up to an hour), a higher chance of being overweight or obese (up to 2.4 times), less likelihood of eating breakfast and increased odds of being tired in the morning.
Actionable step πͺ: Consider setting a tech-free bedtime routine to improve sleep quality, BMI, and energy levels. Here are a few night routine tips:
Start with a quiet activity like reading a book π.
Make the bedroom a tech-free zone π«π±.
Establish a consistent sleep schedule β°.
Keep the room dark and cool for optimal sleep conditions π.
Encourage a healthy breakfast every morning π³.
TAKEAWAY
And there you have it! This week's review has given us some key takeaways:
π¬Study Recap
1οΈβ£ High-Protein Breakfast Affects Weight Loss in Overweight Adolescents
Main Takeaway: Eating a high-protein breakfast (35 grams) can reduce daily hunger, increase daily fullness, improve daily glucose control, and lead to reduced evening snacking compared to a normal protein breakfast.
Actionable Step: Start the day with a high-protein breakfast! Incorporate foods such as eggs, Greek yoghurt, or a protein smoothie into your morning meal. π³π₯
2οΈβ£ Moderate-Intensity Exercise vs High-Intensity Interval Training
Main Takeaway: Both HIIT and moderate-intensity exercise can improve insulin sensitivity by 20% and increase peak oxygen uptake by around 10% in adults with obesity, without necessarily leading to weight loss.
Actionable Step: Engage in regular physical activity, whether it's moderate or high intensity. The key is consistency, so find an activity you enjoy and stick with it! πββοΈποΈββοΈ
3οΈβ£ Bedtime Use of Technology and Sleep Problems in Children
Main Takeaway: Using technology at bedtime is linked to reduced sleep quality and quantity, increased risk of being overweight, and feeling more tired in the morning.
Actionable Step: Implement a "tech-free time" before bed for the whole family. Consider adopting a relaxing night routine that encourages better sleep. π΅π
By paying attention to these studies and incorporating the actionable steps into your routine, you're on your way to a healthier lifestyle! ππ±
