What is the 5:2 Diet?
The 5:2 Diet involves 5 days of "feasting" and 2 days of "fasting". On the "feast" days you can eat "normally", as long as you don't go overboard. On the "fast" days, you eat 25% of the calories of a normal diet. On average, that's 500 calories for women and 600 calories for men. The calories can be eaten all at once (just one meal) or spread out throughout the day.
What are the pro's?
- No food groups are eliminated on the "feast" days
- Increases people's awareness of what they're eating
What are the con's?
- Lethargy and lack of concentration on "fast" days
- Doesn't encourage healthy eating, as you can eat whatever you like on "fast" days
- There is uncertainty and lack of evidence surrounding 'intermittent fasting' and whether it is healthy
- People who continue to make poor food choices on the "feast" days still won't lose weight
- Not sustainable longterm

My thoughts?The 5:2 diet is not sustainable long-term and doesn't teach you the foundations of a good diet. The "fast" days will leave you feeling hungry and lethargic, and with no energy to exercise.
Eat well-balanced, healthy meals with at least 2 serves fish per week, 2 serves legumes/ lentils per week (1 serve = 1/2 cup), 3 serves of low fat dairy a day, 2 serves of fruit and 5 serves of vegetables a day. Allow yourself 1 "cheat" meal a week, perhaps on the weekend, where you eat whatever you like. If you're after something sweet, allow yourself a treat to cure the craving, but be sensible! If you open the packet of tim-tams, eat 1, not the whole packet.
If you eat well-balanced meals, limit your intake of calories from drinks (alcohol, coffee, juices, smoothies, energy drinks) and exercise at least 150 minutes a week; you'll be healthier, happier and have more energy!
