Watch this video and learn more about Yoyo dieting, its immediate and long-term effects on our body.

Hi, this Dr. Justin here. And today’s talk is on the Yoyo dieting.

Well yo-yo dieting is essentially is going on a low-calorie, some kinda extreme diet usually it involves cutting out certain macronutrients. Whether you’d be cutting way down on proteins or fats and essentially restricting calories.

The first thing that happens is that any time you restrict calories in the body, the first thing your body says is, “what was going on?” – is thinking its genetics are hardwired for famine, alright. Something is happening in the environment we gotta be really careful, we gotta conserve our energy. So the first thing when we send that scarcity singles were genetics.The first thing our body thinks is famine. And it’s gonna turn down our thyroid hormone. To our thyroid again, this is essentially the thermostat of our body. So we turn it down a little bit, it gonna basically run a little less energy, run a little colder, maybe a little less brainpower. It’s trying to conserve energy. And then we start to hardwire the metabolism. Instead of it to burn fat and fuel efficiently and easy, we start to tell our body, “ know what, store that energy in the fat cell over rainy day. We’re okay for a little fatigue. You rather have that reservoir or fuel so that if we need it, we got it.”

So again, the first thing we really always wanna do when we’re trying to trying to lose weight is never do Yoyo dieting.  What happens is, you are at this low-calorie state, our weight start to drop, we’re looking good, our clothes are fitting better. But then because we’re around food, right- our will power starts to the lessen and we started eating again. I mean, if you look at the concentration camp victims, in the 1940s they’re all really skinny. But the problem is they didn’t have refrigerator full of food around the corner. They had no chance for willpower to affect things. So we have food everywhere. And as we start to- our weight starts drop, it’s dropping, it’s dropping and “Hey, look at us, we’re fitting into these clothes.” But then our hunger gets worse and worse and worse and then we quit. And when get back in, then we eat and our metabolism’s a little damage. So the effect is the way starts to go up and up and up and up and up. I’m gonna show an illustration overlying the camera view so you can see how it looks. So we start out, we’re heavy, we’re cutting calories, we drop, we drop, we drop. Thyroid function starts to drop then will power kicks in, we can’t maintain it. Weight starts coming up, up. And then it passes then we become even little bit heavier than where we were. So this is the Yoyo effect.

So we start here, we lose a little bit, we come back a little. We lose a little bit, we come back a little more. So the call is we do not want to alter our thyroid hormone for the negative. We actually want to make a lasting change. So its taking into an anti-inflammatory diet, avoiding the most inflammatory foods, essentially grains, dairy and legumes. And eating every 3 to 5 hours. It really is a good way to stabilize blood sugar and send signals to your metabolism, “hey, burn fat for fuel, have lot of energy, use it all up, feel good, perform well.” It gives us the signals to be vital and not to go into a scarcity mode.

I hope this talk benefited you. For any questions, feel free and visit and/or email the office. Thanks. Have a great day.
