About the FastaWeigh 8-week Program

At the first meeting on Tuesday February 12th, we meet for 2.5 hours to learn learn about how to use intermittent fasting and low-carb eating to meet your weight loss and wellness goals. The group then meets weekly on Tuesday evenings for an hour. At the start of each weekly meeting you learn about a new nutrition topic followed by Q&A with Liz and a FastaWeigh support discussion. The course is limited to 10 participants only.

In the workshop and weekly meetings you will learn:

  • How to switch from burning carbohydrates (sugar) as your primary fuel source to burning fat (become fat adapted)

  • The best way to get your body into ketosis (fat burning mode)

  • The role of insulin in metabolic health and weight management (and how to reduce insulin resistance)

  • The role of protein and healthy fats in the diet

  • Foods to eat for gut health and to reduce inflammation in the body

  • How to reduce food cravings and incessant hunger

  • Sleep and stress and their effect on hunger hormones, health and weight

During the program, all FastaWeigh Course members also receive support in a private WhatsApp group accessible only by the course members and Liz.
