Benefits and Risks of Intermittent Fasting
How does intermittent fasting work?
Food is fuel, when we eat insulin levels rise, turning blood sugar (glucose) into energy or to store glucose for future use.
Research shows that 60% of Canadians eat between meals. In the 1960’s and 70’s, the average eating intervals was 3 meals per day. By 2005, people are eating 5 to 6 times a day. This is due to the mistaken belief that smaller frequent meals will increase metabolism and aid in weight loss. Additionally, other factors include the industrialization and accessibility to more processed and fast foods and more complex social issues.
- Simple fast: 12 hours
- Cycle fast: 16 hours, 2 to 3x per week
- Extended fast: 2-3 days
- Time restricted eating: eat all meals in 8 hour period at the same time each day (circadian rhythm)
- Fasting Mimicking diet by Dr. Valter Longo – Eating low carb, high fat, plant protein (5 days)
- Intermittent fasting allows drinking of water, tea, coffee, and broths
