Will Yo-Yo Diets Be a Thing of The Past?

Just the word itself conjures images of ups and down, highs and lows. The ups and downs of Yo-Yo diets are not just in terms of weight lost and gained, but also in terms of mood, feelings of self-worth, and levels of deprivation, physical activity and energy. Yo-Yo dieting is really nasty for your health, but thanks to some new research, we may be closer to discovering who is at risk for this behaviour, and how we can nip it in the bud!

While it's true that all diets bring about highs and lows, Yo-Yo diets not only take a physiological toll on your body but also a psychological one. Yo-Yo dieting is when people lose weight and then gain it back again afterwards, if not even more. It has been found that weight loss isn't people's biggest challenge, it's keeping that weight off that is the hardest part! The thing is, we're finding out that some people are more susceptible to weight gain post-diet than others. Some people just eat what they want and never really gain or lose weight but others quickly bounce back like they were never on a diet to begin with.

Researchers from Cambridge, UK believe that this pattern is somehow linked to the protein angiotensin converting enzyme, or ACE. It is believed that ACE might interfere with the hormones that control how full people feel, and might make their bodies store extra fat and water. This discovery may ultimately lead to the development of a blood test that can detect who is susceptible to these outcomes which can then guide eating practices for healthy, sustainable weight loss.

This test isn't meant or able to fix people's metabolisms or prevent this pattern from happening in a physiological sense, but perhaps the knowledge that crash diets and deprivation will have severe consequences for some people might sway their behaviour towards more sustainable eating practices. It could also potentially be psychologically appeasing to know that there is a way that people can control post-diet weight gain from happening by understanding its cause. Now, we'll just have to wait and see.

I never really understood why these types of diets work. It's called exercise and eating healthy (not going on some food plan that you know isn't right for you just so you lose weight right away)

Metabolism differs from person to person and the diet they choose. I believe if a healthy diet is chosen, the weight should not be a big deal anymore. Some people's built are never really meant to be skinny but everyone can have a healthy and fit body.
