What is the “Fast Diet”, it is also known as the 5:2 intermittent fasting diet, where by for 2 days out of the week you reduce the amount of calories you consume and eat normally for the other 5 days. So the guidelines for following the fast diet are to reduce your calories by a ¼ of your regular intake, so 500 calories for women and 600 calories for men. This plan therefore needs you to consume on the other days of the week 2000 calories for the women and 2400 calories for the men, and not to overeat on these days if you wish to achieve weight loss.
The reason people are talking about this diet plan is due to the simplicity of it. You just reduce your daily calories for 2 non-consecutive days of the week. Then resume with “normal” eating again. There’s no fancy meal plan to try to follow, get bored of or is too complicated to adhere to. There are meal plans available for those who like the details; however you can prepare your own meals as long as you stick to the appropriate calorie limit. You can decide how to consume your daily calories on a fast day, all the various studies adopted different approaches, you can choose one big meal at lunchtime or 2 meals around breakfast and dinner or several smaller meals throughout the day, as long as it amounts to 500 or 600 calories for women and men respectively.
The basic principle to follow for foods to eat on a fast day should be high in protein and fibre, like fish, meats and vegetables. The main foods to avoid include refined carbohydrates (anything rich in sugar or flour), like pasta, rice, potatoes, sweets, cakes, biscuits, etc. The best drinks to consume is water, tea/coffee with no milk (low or no calorie drinks are best). Also safest to avoid alcohol due to the calories they contain and the effect it has on your insulin levels.
This diet not only claims to help you to achieve weight loss, but other health benefits like, improved blood pressure and cholesterol levels, and reduced insulin sensitivity levels. There are people who are not advised to partake in this diet due to numerous reasons, those people may be underweight people, children, pregnant or breastfeeding women, diabetics, people recovering from surgery, people who have an eating disorder or people who just aren’t feeling well. People may be concerned about what they have heard about ‘starvation mode’ and that this fast diet may cause this to their body. Rest assured that ‘starvation mode’ only occurs after weeks of extreme caloric deprivation, not after one day of low caloric eating.
In reference to exercise and whether it is safe to do while following the fast diet, it is entirely up to you. If you feel you have the energy to exercise then feel free to slog it out at the gym. However, be mindful of not training too hard with endurance activities.
Once you have reached you goal weight (if weight loss is what you aimed to achieve) it is recommended that you continue at least one fast day a week. There are many more details, inspirational stories and research around this new phenomenon that is taking the world by storm through the website http://thefastdiet.co.uk/ or through their books ‘The Fast Diet’ and the corresponding recipe book. Once you embrace the idea of intermittent fasting you will discover that your preferences towards food change, you have greater control over your cravings in between meals and that fear of hunger no longer dominates you.
