Hi Sammy!
It's great to see that you have made the first and the most important step - joining this forum for support and information. The first step is usually the hardest one to make, but after that you just need to keep the pace
I have tried many different programs throughout my life, because I sometimes tend to let my body go out of shape and then I need some motivation to get me going. This time I discovered this almost magical recipe that never ever leaves me hungry and (step by step) destroys my cravings... funny thing, it used to be the opposite with diets. I started with two rules: no wheat and no sugar. With at least 2 big formal family dinners per week, it was hard to keep to my regime all the time, but I managed for about 80% of each week to keep to my program and the rest of the time I basically binged. Nontheless, the fat kept melting off at an average speed of 1.5 - 2 pounds a weekand as time went by, I craved less and less sugar and wheat. Also, while doing it, I realized that I am most probably gluten sensitive, so eventually I cut 99% of gluten out of my diet. I still eat it sometimes but I feel strange afterwards. Cutting out sugar is important for me, because it makes me crave for cookies, cakes, bread and the likes that I'm not supposed to be eating anyway. If I really want to bake, I try to use as little wheat flour as possible and substitute sugar with more natural sweeties such as honey or maple sirup. This little detail really makes a difference on how I am able to keep to my diet!
Not eating wheat means not eating many of the processed foods that are bad for my health and induce weight gain. Also, it automatically reduces the amount of calories I eat with every meal. If I need more energy because I have done a lot of exercise, I prepare a dish with lentils or beans instead of pasta.
I also try to stay to minimal "added fat" when preparing my meals. This means that I use very little oil and butter for cooking. My body still needs fat to function, especially during the nordic winter, but it's much better to get the fat from a handful of nuts (walnuts, pecans, pumpkin seeds...) a day or from an avocado, because they have many more vitamins than oils and butter. More vitamins with every meal = more satisfaction after eating
As for exercise, starting by 5min a day and adding 1min every day is an excellent way to start motivating yourself. Once you get going, it's easier to keep going
I hope I helped and welcome!
