The former gieffina Mia Cellini before participating in Big Brother had explained that she had lost 65 kilos in a year, going from 130 kilos gained after the bereavement of a parent to 69 kilos of her current weight, a weight in which Mia is comfortable, to at ease and in perfect physical shape and health. Recently, Cellini explained in a video how she managed to lose weight and maintain weight, and on Afternoon Five she explained her current maintenance diet.
The secret of Mia Cellini’s diet is simple:Mia counted calories to lose weight. This way she didn’t deprive herself of anything, but she simply reduced the portions and counted the calories for each food. In truth, as she herself admits, at first she followed a more drastic diet in order to lose weight, but then she came to terms with illness (fainting) and balanced the diet better up to what we read below ( by way of example).
Here is Mia Cellini’s diet.

1500 calorie maintenance plan.

Snack and snack as per the 1200 calorie diet. 
Lunch: half a level glass of rice or a glass of pasta (raw) cooked with vegetables and 1 teaspoon of oil. Second course of vegetables of your choice, raw or cooked, with a teaspoon of oil. 100 grams of fruit of your choice. A coffee or herbal tea with stevia.
Dinner: a 1200 calorie protein main course, with a vegetable side dish and 1-2 teaspoon of oil. A small sandwich. 100 grams of fruit of your choice.

What I think of Mia Cellini’s diet: Cellini says she does the gym although not always, and she also says she underwent abdominoplasty after weight loss. Abdominoplasty aside, considering her young age and her desire to keep fit, 1500 calories are few, given her current weight, age and height (172 cm, weight about 68 kilos). It would make sense to rely on a sports nutritionist if you work out at the gym, and in any case start increasing calories by aiming for an activity such as weights or crossfit two or three times a week , until you reach a more acceptable food solution in the long term, for example 1800 -2000 calories. Not only by increasing them a little at a time (for example 50 calories a week or 100 calories a month) would not gain weight,but it would also have a healthier metabolism.
A reverse diet  , for example, would be a solution to not feel like a diet for life.
