Do weight loss shakes work?


Weight loss shakes can be a great option for people who don't have a lot of time to prepare a nutritiously balanced meal for breakfast, lunch and dinner. Meal replacement shake diets can work very well if you follow them and don't overindulge. If you're having a shake for breakfast and lunch for instance and then having a healthy dinner, it would be hard to not lose weight.

Introducing exercise into your lifestyle is also an important aspect to ensuring the shake diet works for you. Even if it's just a 30 minute walk after dinner, while gradually building it up to more strenuous exercise, you will start to see results rather quickly.

Are weight loss shakes safe and healthy?

Weight loss shake diets are not intended to be something that you follow for the rest of your life, it is usually suggested that you don't do them for more then 12 weeks at a time. They are intended to kick-start your weight loss, and make your life easy when trying to eat healthy. They are packed full of vitamins and usually have a balanced amount of protein and fibre. The evening meal that you prepare yourself needs to be a healthy balanced meal too, to ensure you're getting all the right nutrients into your body.

Some people complain about headaches when they start a shake diet, however this is usually due to a lack of water. When you start the diet, it is very important that you consumed the recommended water for the day. This helps flush the body of toxins and also helps to shift the fat in your body. Drinking water when you're feeling hungry can also be a great way to curve the hunger pangs too!

    On the Optifast website it states the ingredients in their shakes includes Fish Oil, which is not included in a vegetarian diet. What info is correct and which of the other ones listed here also contain animal products that you haven’t listed?
    Confused Vegetrian!

      Hello Sharon,

      Thank you for your question.

      It is good to know that you have done your research on the Optifast shakes by visiting their website directly.
      As it is their product, their information should be accurate.

      Your observation that Optifast was listed as being suitable for a vegetarian diet when it contains fish oil is well noted.
      We shall have this information updated at the soonest possible time. We shall also see to it that the other products mentioned in the article will be reviewed as well.

    I want to try something that will help me lose weight without having to give up all of my food. I love eating and am currently a size 10 – 12. I would ideally like to get down to a size 8-10 (aim of losing approx 5 kg). Shakes would be something I would consider, but would only like to swap one meal per day and keep eating 2 meals. I am fairly active, but also travel for work a lot and need something that is easy to do while on the go. Can you please advise the best product for me to use? Thanks Lauren.

      Hi Lauren,

      Thanks for your inquiry

Meal replacement shakes diets can work very well if you follow them and don’t overindulge. If you’re having a shake for breakfast and lunch for instance and then having a healthy dinner, it would be hard to not lose weight.

      I can’t single out 1 product and say it is the best because all of them will help you in your goal to lose weight. The main difference among these products is the price and where you buy it from. It would be your decision which one to choose. I would also recommend seeking advice from a fitness instructor op a nutritionist to help you further.

      Hope this information helps
