    no! don’t eat dairy it has hormones in it that are meant for weight gain.

    Low fat dairy is not such a good idea and instead it’s much better to
    choose almonds, broccoli, kale, sesame seeds or other sources of calcium.

      Absolutely, you can’t escape thermodynamics. If your Base Metabolic Rate +
      your activity is greater than your caloric intake, you will lose weight. A
      drop in BMR is a given when dieting, though. Many people fail to account
      for that, but it is crucial.

      It’s not for everyone and counting calories can become obsessive. I know I
      can’t do it. I just eat high protein, fresh f&v and so sugar.

      BMR drops around 1000kcal for every 10kg lost(roughly)

    What if I don’t have the appetite to eat 3 meals a day? I can barely eat

      Then you should see a doctor because that’s not normal :/

    • ❤Tiffany Jade❤

      August 27, 2016 at 4:24 pm

      yeah thats really unsafe, maybe you should try eating more. slowly increase
      the amount you’re eating so your body can get used to having 3 meals a day.

    • Akalion

      August 29, 2016 at 12:11 pm

      Then don’t. It doesn’t matter if you eat 5×400 calorie meals or 1×2000
      calorie meal. For the longest time in human history no one ever ate three
      meals per day.

      Best advice here.
      Seek professional advice on the subject, there are a lot of variables that
      can lead to a lack of appetite

      +Stuffy McCuffin Healthier compared to what? Also just re-checking in to
      prove you wrong: Lost 74 pounds now on a ballanced diet, but that still is
      mostly consistent of animal products (meat and eggs mostly, so many eggs).
      Also, I have had no health problems arise because of it.

    Adding protein and low fat dairy is a terrible idea to loose weight. I lost
    all my weight over time just dropping dairy for lots of green veggies and
    eating between 10-15% of my daily intake from protein. The fat you eat is
    literally the fat you wear so the best thing to do is cut almost all fat
    and add in what you need with nuts, seeds and avocado

      Most stupid comment I’ve ever seen. Fats are good for body. Any thing in
      excess is bad

    • Chris Wood (Chrisw8671)

      October 15, 2016 at 3:02 pm

      MAAZ ahmed no one said fat is bad. About 15% of calories as fat is healthy
      where as most people eat way too much and pile on the pounds. In my comment
      i meant get rid of the unhealthy fats and replace them with healthy fats
      such as nuts and avocado. I was not saying all fats are bad as that would
      be nonsensical.

    I found a TERRIBLE way to lose weight. I stay up all night, sleep my full 8
    hours by sleeping from 6am to 3pm and I eat less meals a day cause when I
    wake up I eat “breakfast” and later till around 7 or 8 I eat my last meal
    and what keeps me from going to the fridge at night is that I could wake up
    my parents near the fridge. This schedule works if you don’t have school or
    work at the time. Why I think it’s bad is cause it fucks way too much with
    your schedule once you need to do something in the morning or if your
    friends are going out to eat while your full and once you star working or
    go to school in the morning you have to adjust to a whole new schedule. IM

      weak and I could barely walk straight or concentrate in school and my arms
      would shake all the time. I really don’t recommend it. 🙁

      actually, that won’t be as effective as just cutting down on what you eat
      on a daily basis. if you intake just enough food to stay relatively
      healthy, your body will continue just going as normal, but if there’s a
      sudden lack of intake in calories your body goes into like… battery-saver
      mode, but with calories, and you dont lose as much weight as you would

    I eat healthy, excersize and count calories, but around 11 or 12 when I go
    to bed I get really really hungry, should I just ignore this or eat even
    though it’s late…and also does anyone know why I’m always hungry at night
    in the first place? :/

    • Theresa Castello

      September 23, 2016 at 9:58 am

      I always get hungry too late at night but if you want to lose weight, drink
      a glass of water or tea a little before going to bed so your stomach
      doesn’t hurt, but once you’re asleep, you won’t feel the hunger and you’ll
      just have breakfast when you wake up 🙂

      Rode Depends on the juice maybe. If its a blend of fruits and veggies
      you’re in a GREAT position. If its just regular ol’ minute made juice then
      thats just sugar and water. Although OF COURSE minute made is always better
      than nothing 🙂
