I've just lost 4 pounds in 10 days. I stuck to 1200 cals a day, walked 16000 steps or more a day and did a PMA fitness HIIT each morning.
I'm quite fit so this wasn't new exercise for me but the reduction in cals was hard as I usually eat all my activity calories.
As a pp said you really do have to want it. I needed to wear a dress today when meeting the in laws at a socially distanced picnic. I still have 4lbs to get to normal weight so will carry on with my 1200 cals then go up to 1900 maintenance.
I cut the alcohol and bread as they are just too high in cals.
I do eat 2 or even sometimes 3 bars of moser Roth (aldi) 85% chocolate every day within my calorie limit I couldnt do this without some treats.
I mainly eat veg which I love and salad which I love and grow in the garden.
I tend to have one piece of meat or fish a day plus I eat loads and loads of Total 0% yoghurt.
It's also easier for me as we dont eat family meals as no-one likes the same thing so I tend to cook chicken and then it gets served 4 different ways...!
If your head is in the game you will succeed with this.
Good luck op
