Yes, weight loss shakes can work. That’s the short answer, but only if you follow the guidelines properly and really commit to the challenge. However, weight loss shakes are not a magic solution or magic diet pill that will see you shedding kilos in no time. Losing weight requires patience, dedication, and willpower.
Ultimately, the best weight loss shakes should keep you full and satisfied between meals, to avoid naughty temptations. The danger of consuming shakes with very few calories (usually between 50-200 calories per serve) is that you could end up more prone to snacking or even turn to the sort of meals you are supposed to be replacing.
When asked whether they have lost weight using diet shakes, survey respondents told us:
Weight loss shakes are claimed to be made with a combination of different fibres, proteins, vitamins and minerals, plus some other additives and flavours depending on the brand.
Keep in mind that it’s important to check the sugar content of weight loss shakes, which can vary significantly across different products. It’s the same case with protein bars. Some products are packed with over 20g of sugar per serve, while others include less than 2g. Not only is consuming an excessive amount of sugar bad for you, but it’s also unlikely to suppress your appetite for long. If you want a weight loss shake that keeps you full for as long as possible, it could be worth looking at those with a large amount of protein.
Using diet shakes to replace one or two meals each day can prove to be an expensive way to drop the kilos. Our survey revealed Aussies are spending an average of $61 on diet shakes per month.
A useful way to judge whether it’s worth trying diet shakes, at least in terms of cost, is to work out how much you would normally spend on the meals that you’re replacing. However, there can be a significant difference in price between brands, so make sure to check how many servings you’re getting for your money. Generally speaking, buying meal replacement shakes in bulk is the cheapest way to go. Some diet drinks also come in sachets – which makes it easy to work out how many you will need for a week or month – while others come in large tubs, requiring a little more brainpower to determine how much you’ll need.
