I went through a few years of eating junk knowing i shouldn't, wanting to lose weight but just could not stop myself- each time i would say "ok, thats it! no more junk foods" but i would go back for more. I decided that i needed to sort "me" out first before i could think about my eating habbits. I knew i had no faith in myself, no confidance but also knew i had something to offer- it was a battle. Once i started talking about everything i found the motivation i needed to sort my body out. I found foods that i loved but were healthy so did not feel as bad for eating them (like sushi
) I then was able to cut out the junk foods as i wanted to eat other foods. It takes time to change a habbit and sometimes thats all it is- just eating out of habbit. Apparently it takes 21 days so just set yourself a goal of eating no junk foods for 21 days then work on the rest. there might still be times when you want something junky but its usually when you have not been eating enough of the right foods or drinking enough water- the less water i drink the more junk i crave.
Make food easy- if you need to cook in bulk so all you do at night is press start on the microwave then so be it, make your lunch up to take to work, if you dont and just tell yourself that you will buy a salad at lunch then by the time you get away from your desk to get lunch your hungry and therefore the cravings will have hit and be wanting junk foods but if you have lunch ready to go then its easier to eat the healthy food.
There are hundreds of diet plans out there but you need to do what suits you- it might be a case of trial and error, some do fine just cutting out bad foods and eating the right ones but others need a kick start or help planning meals, just see what works for you and your lifestyle.
