What are you starting from?
I went from 108 in August 23 to 42 in November 23.
I switched sugar drinks for water with a small dash of sugar free lime cordial and the occasional sugar free tonic water or cola for 4 weeks then started to drink more sugar free cola.
I stopped all sweets and chocolates for 8 weeks and then started to eat 1 or 2 mini chocolates a couple of times a week. I get around my need for sweet things by buying low calorie snacks, looking at the carbs and sugars (things with less than 3grams per bar) and allowed myself rich tea biscuits which are low in sugar.
I have recently found Stevia sweetener which doesn’t contain carbs or sugars which I add to plain yoghurt and can use in cooking.
The biggest change was carbs. I switched potatoes to sweet potatoes for mash, chips, etc and increased salad with meals, and cut the amounts of rice and pasta I eat. I also increased the protein in my diet.
The thing that surprised me was the sugars in fruit. I ate a lot of grapes and strawberries so swapped them for apples.
It can be difficult to maintain but is worth it.
I also lost 5kg in that time and reduced my cholesterol from 6 to 2.5.
My biggest problem now is that my sugars are dropping to below 4 during the day so have had my meds reduced while I get the balance right.
Good luck. It is achievable.
