With growing evidence to suggest there are real health benefits to fasting, I decided to make a small tweak to my daily routine by skipping breakfast for two weeks to see how — or if — it had any impact.

Many models and celebrities, including Miranda Kerr and Beyonce, reportedly swear by variations of fasting regimens.

There's the 5:2, where you eat what you want for five days of the week but restrict your calorie intake to just 500 a day for two "fasting" days, or the 16:8, which sees you eat within an eight-hour period, then fast for the remaining 16. There's also The 2 Meal Day — which, as the name suggests, requires eating just two meals in a day, and skipping either breakfast or dinner.

I've always struggled to stick to a strict diet. Restricting certain foods just makes me crave them even more, and calorie counting has always bored me. Advocates say that fasting can give you more energy, make you eat less, and even lose weight — so I was intrigued as to whether it would suit my lifestyle.

I made a small, manageable tweak to my daily routine by skipping breakfast each morning, thus creating a fasting window of between 15 and 16 hours a day. This meant eating my evening meal by 8 p.m. or 9 p.m. at the latest, and breaking my fast at midday each day. The plan was to do it for two weeks — but it turned into three.
