Honestly, by going low carb and cutting out refined sugars.
When you eat carbohydrates and refined sugars, it converts into glucose which causes insulin to spike. When there is too much insulin in the body through constantly eating high carb meals throughout the day, the body is unable to get rid of this ( due to lack of time before the next spike or inactivity to burn it off) As a result of this, it gets converted to fat and this is how it is stored.
So to get rid of it, you reduce your intake of carbs and sugar, so your body doesn't have so much of it to deal with and you allow your body to tap into its own fat stores. This is what results in the weight loss. Have a look at low carb eating and get some more information. I am currently following a ketogenic/carnivore lifestyle and have been since April 2023. I have lost over 16kgs in the first 15 weeks which brought me to my goal weight. I have been in maintenance mode since. In addition to this I do not have the pain in my joints that I get when eating carbs known as inflammation. I wake up with ease in the mornings, not groggy and slow to start, concentration has improved, less hunger throughout the day, I mainly eat one meal a day due to the correct foods keeping me satisfied and do Intermittent fasting with around 20 hours between meals (this can be adapted to suite individual preference)
This has made me change my mind set and relationship with food as I now know foods that hurt me and foods that help me. This helps me make certain decisions when buying/eating.
When loosing weight, the change has to be sustainable and its not just about loosing the weight and then eating how you previously did as this will cause weight regain. This is something I have learned so continue with the lifestyle I have chose.
Hope this helps and sorry for the long post.
