FAQs
Is diet protein good for weight loss?
There is a lot of information out there about protein shakes and weight loss – Holly Roper, our in-house registered nutritionist says: “Protein powders may help you lose weight when used alongside a consistent exercise regime. Consuming protein, in the form of wholefood sources or in a protein shake, helps us feel fuller for longer which may contribute to a reduction in unwanted cravings or snacking. If your goal is weight loss, then it’s recommended you opt for a low-calorie protein powder, and don’t forget to read the recommended serving size, as this can often change depending on the type of protein powder.”
Can diet whey be used as a meal replacement?
Wondering if you can use diet whey as a meal replacement? Our in-house registered nutritionist, Holly Roper, says: “Diet whey can be used as a meal replacement. It is recommended to be used alongside a balanced diet, and you should only replace one or two of your daily meals over a short period of time. This is because, if used too much, you may put yourself at risk of missing out on all-important macro and micronutrients, as well as fibre.”
What is lean protein?
Lean protein is a type of protein that contains minimal amounts of fat and is low in calories. It typically comes from sources such as poultry, fish, lean cuts of meat, eggs, low-fat dairy products, legumes, and tofu, but you can also find it in the form of protein powders. Lean protein is the best choice for those who are looking to maintain or build their muscle mass or manage their weight.
What does diet protein powder do?
Diet protein powder supplements can help support weight loss efforts by providing a convenient and low-calorie source of protein. They promote feelings of fullness, preserve lean muscle mass, and aid in post-exercise recovery, all of which are beneficial for weight management.
