What causes obesity?
Obesity is a condition caused by a range of multiple factors including consuming excessive amounts of calories, lack of physical activity, genetics, and medical reasons.(4,5)
Calories
The general recommendation is for women to consume 2000 calories daily, and for men to consume 2500 calories daily to maintain a healthy weight. Overtime, poor diet, and lifestyle choices can lead to Obesity.
A few examples include:
1. Consuming large amounts of processed or fast foods high in fat and sugar
2. Drinking too much alcohol
3. Eating large portions of food
4. Comfort eating due to low self-esteem or feeling depressed
Lack of physical activity
Nowadays most jobs are office based resulting in people having more sedentary lifestyles. If you are not keeping active enough, you do not use the energy provided by food you eat and the extra energy you consume is stored by the body as fat.
Genetics
Rare genetic conditions such as Prader-Wili syndrome may lead to obesity but most of the time, obesity results from complex interactions between environmental factors and a few multiple genes. This is a growing area of research and still requires more understanding.(4,5)
Medical Reasons
A few underlying medical can contribute to weight gain. For example, an underactive thyroid also known as hypothyroidism where your body does not produce enough hormones. Another condition includes Cushing’s syndrome, a rare disorder causing the over-production of steroid hormones.(4,5)
If these conditions are properly diagnosed and treated, they pose less of a barrier to weight-loss. Certain medications also including antidepressants and corticosteroids can contribute to weight gain.(4,5)

The Eatwell Guide is a good place to start when you are looking to educate yourself more around having a healthy balanced diet.(13) You want to focus on having a good variety of wholegrain carbohydrates, lean sources of protein and plenty of fruits and vegetables.
If you are either overweight or obese, it would be a good idea to focus on losing some weight.(14) You first want to focus on creating a calorie deficit, which means consuming less calories than what you burn in a day.
For some people, reducing portions overall can be enough to lose a few pounds but for others, you may need something a little more weight-loss intensive. This includes embarking on a short-term dietary intervention of choice including following a partial or total diet replacement diet.(11)
How can meal replacement help obesity?
Meal replacements can be a short-term, useful way to lose weight especially if you lead a busy lifestyle.(15,16) You can focus on educating yourself on what a healthy balanced diet is whilst losing weight.
Exante have a range of plans for you to choose from, depending on what you’re looking to aim for. I would suggest started with the Exante 1200 plan and monitoring your weight thereafter. If you are not managing to lose the recommended 0.5-1.0 kg per week weight-goal, then you could try exante 800 plan for a few weeks and see how you get on.
Once you reach your desired weight-goal, which can be calculated using the exante BMI calculator, you can then transfer over to a healthy balanced lifestyle. If you enjoyed using the exante meal replacements, you can still purchase some of them. The porridge pots are especially handy if you are on the go!
Meal replacements are not a fad, if they are used correctly, they can be effective in achieving your desired weight-loss goal and can also be used as part of a healthy balanced lifestyle.
