ACS and Dieting - Do Diets Really Work?

Let’s face it, there are many diets out there today that promote things such as weight loss, disease prevention or cures, sports improvement etc, but not all of these diets are healthy or safe. Navigating through the ever changing fad diets can be challenging, not only for healthcare professionals, but for our patients as well. Furthermore, there is no evidence of any long term sustainability of dieting. People often end up with a yo-yo effect of weight loss, weight regain, and then dieting again. 

Fad diets can be harmful if they:

  • Say you need to cut out many healthy foods or whole food groups

  • Put people in a cycle of weight loss and weight gain

  • Suggest you eat too few calories to fuel your daily activities

  • Make you become so focused on food that it begins to:

    • Control your life

    • Prevent you from enjoying daily activities

Other considerations:

  • False hope - fad diets make promises they can’t keep by offering “too good to be true” results

  • Feeling of failure - people feel a sense of guilt and are set up for failure

  • Money - many products are expensive

  • Avoiding real change

Ways to spot a fad diet:

  • Promises quick weight loss

  • Flaunts famous names

  • Limits or cuts out whole food groups

  • Uses testimony instead of science

  • Endorses no exercise involved

  • Sells something (like food or pills)

  • Claims to have “secret ingredients”

  • Tells you to disbelieve doctors

Tips for adopting healthy dietary patterns: 

  • Don’t overthink it - look at an optional balance of healthy fats, proteins and carbs

  • Choose food that fits into your budget, preferences, and culture

  • Prepare meals at home - eat out/order in less

  • Sit down and eat with family or friends

  • Be mindful of your eating- turn off the TV/screens and take the time to enjoy and “taste” your food

  • Don’t make certain foods “illegal” or “forbidden”

  • Fuel your body with fibre and protein

  • It’s ok to enjoy treats once in a while!
