- Sarah Berry responds with 'Yes'.
Snacking: Friend or Foe?
- Snacking is a controversial topic with a three-way split in opinions - 36% say it's healthy, 32% say it's not, and 31% are unsure.
- There's no clear definition of a snack, but it's generally considered as an eating event between main meals or after dinner.
- About 25% of energy in the UK and US comes from snacks, with 75% of it coming from unhealthy ultra-processed snacks.
- Snacking on unhealthy snacks causes a rapid rise in blood sugar, leading to metabolic chaos and inflammation.
- Unhealthy snacks lead to a roller coaster effect on blood sugar, causing increased hunger and energy intake, and making you eat more at the next meal.
- Ultra-processed snacks have adverse effects on gut health, contributing to long-term problems and reducing the state of gut microbes and the immune system.
- Eating frequency, snacking quality, and timing are important factors to consider when evaluating the health impact of snacking.
- Historically, people were encouraged to snack more frequently, but recent data suggests that frequent snacking may not be as healthy as previously thought.
Snacking Does Not Impact Health
- Researchers found that many people under-report what they eat, leading to inaccurate data analysis.
- People who eat more frequently tend to consume more energy and have a slightly higher BMI.
- Randomized control trials show no difference in weight or cardiometabolic health outcomes for those who snack on healthy foods throughout the day.
- Tim Spector emphasizes the importance of healthy breakfast and longer fasting periods for better health.
- Sarah Berry's research supports the idea that snacking on healthy foods throughout the day has no unfavorable effects.
Late-night snacking disrupts metabolism
- Sarah Berry emphasizes the importance of snack frequency, quality, and timing. Late-night snacking has unfavorable impacts on health, leading to increased hunger and disrupting the body's natural metabolism.
- Tim Spector highlights the negative effects of eating late at night and the importance of a 12-hour window of not eating overnight for the body's repair and rest. Time-restricted eating has shown improved metabolic outcomes despite consuming the same amount of energy.
- Jonathan Wolff shares his personal experience with intermittent fasting, finding that he could perform well at the gym in the morning without breakfast, challenging the traditional notion of needing energy before exercise.
Snacking: Friend or Foe?
- Population studies show that people who snack more eat more calories, but clinical trials do not confirm this.
- Snacking may lead to eating less at the following meal, balancing out calorie intake over time.
- Eating snacks earlier in the day, if high quality, has no unfavorable effects on health, while snacking after 9 PM is associated with unfavorable BMI and cardiovascular factors.
- Snacking frequency is increasing, especially with unhealthy ultra-processed snacks.
- It's important to be aware of personal biases and cultural influences when considering snacking habits.
- Fruit, nuts, and vegetables are generally better snack options, but the choice within these categories is important for individual blood sugar responses.
