Obsess over "belly rolls" when they leaned forward, despite the fact that everyone gets them. It's a destructive and idealistic outlook.Striving to look picture perfect every day is as unrealistic as it is unhelpful. The best we can settle for is living a healthy life featuring adequate exercise and a moderated food intake. Do it for your health, and the benefits of feeling better throughout the day and feeling better about yourself will follow.If I were you or someone close to you, I would suggest you go out to speak with a tutor or other designated helpful person where you attend and seek advice to receive counselling. Many unis offer free counselling services, which will help give you a healthier outlook on life. There may be a wait list, but I know someone who receives therapy this way and it's helped them tremendously to have an outlet and a patient ear to talk to.Finally, once you are able to acquire a balanced insight into body dysmorphia, I would investigate whether so called "body recomposition" would be a beneficial course of action. It might be, or it might not, but it's never a good idea to launch into weight loss without considering all of the above thoroughly.I would start by looking at lots and lots of body fat percentage charts, and seeing where you place. Then, I would try counting your calories using an app. There are many out there, some free and some paid, but I would go by online reviews and what you prefer. For a few weeks, eat normally and note how many calories you consume, making sure to include drinks and condiments, and also track your exercise accurately. Based on what you weigh, your current body fat % and your goal %, work out how many kg difference there are and adjust your diet. The body follows the principle of conservation of energy, meaning that if you require 2200kcal per day, and eat 1700kcal that day, in order to supply energy, your body will balance the deficit by oxidising the fats stored in your adipose tissues. A calorie deficit of about 7700kcal will produce a net loss of about 1kg, but adipose tissue stores water too, so the weight loss may actually be more, so it's really a rough idea. Tracking your food, induce a slight and gradual calorie deficit - shoot for several hundred calories per day, never lose more than about 500 kcal per day. Higher rates of fat loss are not healthy and cause you to rapidly lose muscle mass. The occasional day might prove a setback, as you have a big dinner or a night out, but it's the overall trend you're trying to maintain. I would suggest a diet rich in protein, with some carbs and the fewest oils and sugars that you're able to include in your diet. Oils and simple sugars are extremely energy dense compared to most vegetables and lean meats, so they are less filling. A protein rich diet will also likely decrease your appetite, as well as enable you to start building muscle through cardio and gentle exercise.As for hunger, you usually get used to a deficit very quickly, and it becomes second nature within about 2 weeks. Personally, I used to eat until I was either just full, or very slightly less than full, which worked as a good rule of thumb.If you need any clarification or advice, feel free to reach out
