I am constantly surprised by the number of people that think they can eat fast food junk in ridiculous quantities and think 30 minutes of exercise would make it all good !! IT WILL NOT !! :) Similarly I see (mainly blokes) training at the gym and working hard but can't seem to get rid of the big gut. People will tell you its 80/20 (or 70/30) where it 80% food and 20% exercise and this is so true and we all tend to forget this. Some general tips in particular for those 30+ folks..
- Avoid fast food like the plague. Maccas, hungry jacks, kfc, red rooster etc. NO MORE not even occasionally. Its not worth it.
- Avoid white carbs like the plague too, that includes white rice, pasta, white bread etc.
- Anything deep fried is a definite no.
- Minimize sweets.
- For those specially trying to lose weight, please don't just eat one meal a day, you are making things a lot worse for you. Its counter productive to starve yourself.
- Try to eat 4-5 meals a day (small meals :) I realize this is hard to do especially when we are at work during the day, but try to sneak in a handful of nuts or some fruit in-between and reduce the otherwise massive meal you might have.
- Do not miss breakfast, at least have a cereal bar. Ideally have a big breakfast full of protein and good fats.
- Have your carbs during the day and avoid them after 6pm. So no rice, pasta, pizza, bread etc at night. This is hard if you aren't used to it, so if you absolutely can't avoid it just have a handful of wholemeal and unprocessed carbs if you must.
- Make sure you have a good intake of healthy fats, Salmon, Avocado, Nuts, etc. These are good for you despite being fatty.
- I need not say this but I'll state the obvious - don't smoke and limit your alcohol intake to 3-4 standard drinks a week.
All of the above sounds hard to follow but trust me (I'm a dr. :) once you get into the habit of things and be conscious about what you eat, it will come naturally and you will feel better all around. Good luck !
