Is it possible to lose a lot of weight, for example lose 5 kg in 2 weeks, without affecting the lean mass but attacking the fat mass? According to Zana Morris, personal trainer, yoga teacher and nutrition specialist who runs The Library gym and is considered one of the biggest names in fitness in Britain, yes.
Even in twelve days.
I have already told you about her: in fact, Zana Morris has been arguing for years that the ketogenic diet is the best diet for losing weight quickly, pushing the body to attack the fat reserves.

Parallel to the diet, Zana in her latest book ( The High Fat Diet , written with science journalist Helen Foster) recommends 15 minutes of high-intensity physical activity. But let’s proceed in order starting from the diet.
What should we eat to lose 5 kg in 2 weeks?

HOW TO LOSE 5 KG IN 2 WEEKS: WHICH DIET TO DO

For the first two weeks, Zana recommends a fully ketogenic diet.
That is, we can consume foods that contain proteins and fats, but not carbohydrates.

The diet includes three large meals plus snacks based on meat or fish with a few green leafy vegetables and avocados, or alternatively crustaceans and molluscs. Dairy products in moderation, better aged or creamy cheeses with a high fat content, and eggs for breakfast. I’ll tell you more about it here.

You will say: but then? Once we have lost these 5 kg in 2 weeks how do we maintain the results?
Carbohydrates are reintroduced in moderation.

First a week of a diet of the same type but with the addition of two fruits as a snack. Then, some oats (40, 50 g) or brown rice, as an accompaniment to lunch or dinner.
Then stick to slightly larger quantities, for example by having two slices of bread for dinner or a potato and 30g of unsweetened oat flakes for breakfast, perhaps pairing the short activity of the first few weeks with a little cardio and indulging in a day off.

But the pattern always tends to be low carbohydrates even in maintenance. If we fail, we return to the initial diet for a few days. But the ketogenic diet alone is not enough. It is necessary to plan 15 minutes of physical activity per day. But let’s see what kind.
