Hey, welcome along
1.) The best cardio workout is one you can stick to, if you cant see yourself being the person who goes for a run every night then dont do it, youll end up giving up and feel like youve failed. Start off small, walk to the shops instead of driving take a 15 minute walk before dinner anything is a great start and you can work your way up from there! alot of people give up because they set such high expectations of themselves.
2.) Pepsi max isnt good but it isnt that bad, some people have bad reactions to the artificial sugar and some dont. Having one can every 2 days isnt a problem at all, its all about moderation not about completely cutting out things you enjoy, if you like it and dont have any adverse reactions to it then keep drinking it
3.) I dont see how having an irregular job could be bad at all, people confined to wheelchairs can still lose weight so any king of incedental excercise you do is a great help.
4.) Dry noodles can be very bad! they are often fried and have no nutrition at all - they are completely empty calories. If you have to eat them there are healthier baked versions out these days but making some sandwiches to take to work with you would make a big difference to your diet.
5.) Fruit has alot of sugar in it, but its a great option instead of the dry noodles and because your job is so active you would use the sugar for energy before it turns to fat, i think eating that much fruit if your sedentry would be a problem but for you it would be a good energy food with lots of nutrients and fibre.
6.) Low carb beer is all relative, it makes a difference if your replacing it with plain old beer, alot of them are lower in calories and being lower in carbs you'll feel less bloated but dont use it as an excuse to be able to drink twice as much of it! its better but its still not good sadly
7.) Most meats are good for weightloss, chicken breast and lean meats are very low calorie options, the less processed it is the better! and fish is a fantastic substitute for meat a couple of nights a week.
8.) Calorie counting works well for me, but i only started it once i started plateauing with my weight loss, it takes alot of work and can sometimes make you a bit obsessive weighing everything and trying to remember every morsel you eat. I would try eating healthy first and if your losing weight keep at it and there probably isnt a need for calorie counting, but if your not losing weight then it would be worth a shot. And lastly.. its not good to eat bad stuff at lunch and then skip dinner, skipping dinner might make you binge later you would be better to make up for your mcflurrys by doing a bit of extra exercise.
Hope this helps, Jules
