When it comes to weight loss, slow and steady wins the race. Rather than going on a intense diet which will wreck havoc on your mood, put unnecessary strain on your body, sap out some of the joy that you should be experiencing this year as a senior, slow your metabolism down so that you will have a much more challenging time losing weight in the future, and possibly cause skin problems which will be far more noticeable in the photos, why don't you find a fantastic makeup artist who can help to create the illusion of a slimmer face, and wear figure-flattering clothes? I am perpetually in awe at the way makeup, lighting and clothes can completely transform the way a person looks. My best friend had been self-conscious about her weight before prom, and I was stunned by how much expertly applied makeup, a few highlights in her hair, and control top panty hose (she wore something called Spanx) slimmed her. She also had a facial the day before prom that helped to eliminate the puffiness in her face. There are heaps of tutorial videos on YouTube about how to appear to be slimmer.
Focus on losing weight long-term by changing your habits, not dieting. Drink plenty of water and green tea which will not only help to keep you slimmer, but will make your skin healthy and lovely. Eliminate as much processed food and sugar from your diet, and avoid "white" foods like mayo, pasta, rice, and potatoes. Replace white bread with whole grain bread. Have plenty of fresh fruit and vegetables a day, and make sure you're getting enough protein. I'm a vegan, so I rely on non-animal sources, but eat whatever lean protein you prefer. Avoid things that are marketed as being low-fat and for dieters because they are just gimmicks, and not genuinely healthier for you. I read an article a doctor wrote about how Snackwell had done more harm to the American diet than chocolate bars, chips and McDonald's because it gave people the false idea that they were eating something healthy when it was actually loaded with sugar and carbs, and highly processed. You're much better off having some sliced pineapple, a small piece of dark chocolate or even a few whole grain chips and salsa.
Incorporate exercise into your daily life because it will make you look, feel and think better. I carve out time every morning to exercise because it wakes me up and energizes me, and it helps me to focus. I dance, do yoga, surf, play tennis, run and swim, but do whatever you love the most. Pilates will give you an amazing physique. Shape Magazine has a work-out playlist on their site every month, and it gives you some ideas on fun music to keep you motivated.
Read tips on how to pose in flattering angles, and plan out your wardrobe carefully if you are wearing an outfit of your choice rather than a gap and gown or uniform. Avoid stripes and patterns which look distracting on camera and give you the appearance of being heavier, and instead wear a darker shade of a color that will enhance your eye and hair color.
