Foods to avoid when losing weight

If you're a mum who wants to lose weight and keep it off, you're not alone. Whether you're a new mum or you are later down the track weight loss is often a concern. Weight loss is one of the top priorities for many mums, but they don't know where to start.


The internet is full of information on popular diets, but these quick fixes rarely work long-term. Instead, a commitment to consistent healthy eating and regular physical activity is what will get you back to a healthy weight. 


Understanding which foods to avoid is a great place to start. 


Top Foods to Avoid When Losing Weight


Fast Food

This might seem like an obvious one, but fast food is the number one food to avoid when trying to lose weight. Fast food is highly processed, contains tonnes of hidden sugar and is cooked in huge amounts of unhealthy oil in cooking. A large Big Mac meal contains a whopping 1015 calories. To put that into perspective, that's over half the generic woman's daily calorie allowance as recommended by the NHS


The easiest way to avoid fast food is to be prepared. If you know you're going on a long car trip, take a packed lunch with you. If a Friday night takeaway is a family tradition, why not make a compromise? Instead of ordering a chicken burger meal, make a healthy chicken salad and order in the chips. Or order roasted chicken with a side of veggies. This way, you'll save yourself around 500 calories and avoid lots of unneeded sugar, fats and oils. 


Sweet Treats

We would never recommend cutting out sweet treats completely; that would just be cruel! But if you seriously want to lose weight, cutting back on sugary snacks is vital. High sugar treats are one of the main inhibitors for weight loss. And it's often because people don't realise how quickly the calories add up when they have a little treat here and there. 


Just 20 M&M's has over 100 calories. That's more than a protein-packed, nutritious, and filling boiled egg. After eating a boiled egg, you'll most likely feel satiated and full for at least an hour or two. But a handful of M&M's doesn't provide any nutritional goodness, just empty calories and loads of unhealthy sugar, leaving you hungry and looking for your next snack. 


When trying to lose weight, we want to opt for nutrient-dense snacks. Hummus, nuts, vegetable sticks, tinned tuna, fruit and yogurt are all great options. They'll help to keep you full but also provide essential nutrients for you and bub.


If you have a chocolate craving, try the Chocolate Brownie In Shape Mummy Health Shake or Chocolate Breastfeeding Boost Bar.  Salted Caramel Peanut Fudge Protein Bites are another nutritious and delicious option for sweet cravings.


Cooking Oil

It's the quality and the quantity of the oil that is important. Good quality coconut and olive oils and a great addition to any diet. They provide important healthy fats, and rich flavours to foods, and allow us to cook using various methods. However, they're super high in calories, so we need to be very careful with the quantity we use. 


I'm sure we're all guilty of free-pouring olive oil over our veggies before we roast them and then coating our chicken breast before popping it in the frying pan. But just two tablespoons of olive oil contain 238 calories. So when you add the calories of the chicken and vegetables, a meal you thought was healthy is actually one that's leading to inhibited weight loss. 


The best way to avoid consuming too many calories from oil is to use a measuring spoon and reduce the total quantity. Another option is to consider investing in an air fryer or non-stick pans. Both of these kitchen items enable you to cook with far less oil. 


Salad Dressing and Sauces

You might be surprised to see salad dressing and sauces on the list, but these two items are two of the biggest culprits when it comes to hidden sugar. For example, a store-bought tomato sauce contains around 1 tsp of sugar in every serve, and it's not uncommon for a salad dressing to contain up to 10g of sugar per serve. 


The best way to avoid these unnecessary sugars is to make your sauces and dressings at home. A vinaigrette made with a bit of olive oil, water, mustard, and lemon is virtually sugar-free. Or simply balsamic vinegar and olivie oil. In addition to this, making some healthy ingredient swaps will make all the difference. Try swapping mayonnaise for Greek yoghurt and tomato sauce for homemade tomato salsa.  


Soft Drinks

We won't beat around the bush here; soft drinks are a big no-no for anyone wanting to lose weight. A can of Coke contains 39 grams of sugar. That's around 10 grams more than the total maximum recommended intake in a day. A soft drink provides no nutritional benefits and doesn't fill you up. So, in addition to a large amount of sugar you're consuming, you'll also need to add any sugar and calories from your meal or snack. It all ads up. 


The good news is there are lots of delicious low sugar or sugar-free drinks you can have while breastfeeding. Kombucha is a fantastic low sugar option that's still full of flavour and will give you the fizzy hit that comes with a soft drink. Otherwise, sparkling water with some slices of lemon or lime or berries can hit the spot. 


Weight Loss Foods to Avoid

It's important to note that some foods are called 'weight loss foods' that can actually have the opposite effect. Fat-free foods, in particular, may cause more harm than good. The reason is that when the fat is removed from a product, something needs to be added to replace the taste. And the addition is usually sugar.


For example, full-fat yoghurt often doesn't contain any added sugar, whereas the fat-free version may contain up to 14 grams. And, without the fat content, the yoghurt really won't be that filling. So, you may find you are still hungry.

"I've lost 35 kgs thanks to the In Shape Mummy Health Shakes. 110 kgs to 75 kgs! Juggling two little boys under 2 years old doesn't leave much time for healthy choices for Mummy and the In Shape Mummy Health Shake is such an easy solution to get all the goodness I need to keep going! My older son is 20 months and I didn't get the chance to lose the weight gained whilst carrying him before I was pregnant again with baby #2. I easily gained 40kgs across the two pregnancies and no thanks to terrible pelvic pain in pregnancy #2 wasn't able to keep active. Now that my second son is here and the pelvic pain has gone I have stuck to replacing breakfast with my shake and walking every morning for the duration of the morning sleep. Some days I will do a second shorter walk during his nap. I'm still able to enjoy yummy healthy foods and definitely do not feel like I'm going without. I no longer crave sugary foods as the shake sets me up for the day with its magical satisfying ingredients! The shake has become even more of a must since returning to work! If I thought I was busy before, life just got a whole lot busier! Now that I've lost the weight, I have more energy, zero aches and pains and have a better mood. I tell all my friends about In Shape Mummy because easy weight loss doesn't need to be a secret! Xx"

"I discovered In Shape Mummy Health Shakes not long after my second baby was born. He has an intolerance to dairy so I was looking to find something that was safe for breastfeeding, and also vegan friendly. I have recently started a detox program with the help of a naturopath. She was so impressed with the ingredients that she has encouraged me to continue having it! In Shape Mummy has not only helped me lose the 26 kgs I put on in pregnancy, but it’s helped me nourish my body when I’ve been time poor and sleep deprived. It’s the only shake that I actually enjoy the taste of! My breakfast everyday includes ice, almond milk, water, a banana and my In Shape Mummy (my current fave is the caramel fudge!). At 11 months postpartum I feel great! And my breastfeeding journey is still going strong - my milk is in perfect supply for what Bub needs. I cannot recommend In Shape Mummy Health Shakes more highly!”

7-8 months ago I couldn’t have even imagined I could drop this much weight! The change in my life has been insane! ⁠ My advice to other mums is “stick with it and don’t give up!” ⁠ Thanks so very much for your In Shape Mummy Health Shakes. They are the best thing for mums on the go and while breastfeeding as well. Words can not express how grateful I am with my weight loss. I couldn’t of started this without your shakes. My life is forever changed." ⁠
