How do you verify the weight loss?

For all official weigh-ins, you'll be prompted to submit your official starting weight. Our standard weigh-in process involves you submitting 2 photos: one of you standing on a scale in lightweight clothing (no shoes, hats, belts, watches, coats, or outerwear), and another of the scale’s readout with your weigh-in word written on a piece of paper.

What you'll need

  • A scale (preferably digital)
  • A digital camera or smartphone
  • A full-length mirror or someone to take your photo

I did my final way in, and met my goals :-) but after I submitted everything, and joined three new DietBets, the last three DietBets that I was in said runner up? I went into those diet bets and it put my weight at 385 pounds for each of them after I submitted it, did anybody else have this problem?


Send diet bet a message! I had that happen once

  • Ok, is it just me or is this DietBet flying by fast? We are already into week 3, with just 11 days left! Look over these past two weeks. Has it been easy for you to stay on track, or are you struggling? What is your progress like? Are you happy with your progress thus far, or do you think you need to make some adjustments? Feel free to share your thoughts below!

    So, I'm sure you have come across the term "macros" at some point in your journey. You may or may not know what macros are, or understand how they play a role with diet and weight loss. Macros (or macronutrients) come from the Calories of the food you ingest. As you remember, Calories is synonymous with energy production in your body. That energy is either used/excreted by your body, or it is stored. Your body breaks down Calories into three main macro categories: carbohydrates, fat, and protein.

    You can visualize your macros as food groups. As shown in the chart below, some foods can provide both carbohydrates and protein, or protein and fat. Each group provides a varying amount of energy for your body. For example, there are 4 Calories per gram of carbohydrate, 4 Calories per gram of protein, and 9 Calories per gram of fat. This can be the basis for tracking your macro intake. Some people prefer to track macros as opposed to Calories, but even while tracking macros, your Calorie goal will remain the same. Therefore, it is easiest to track Calories while being aware of your general macro intake.

    For most people, an intake range between 45-65% carbohydrate, 10-35% protein, and 20-30% fat is recommended for a balanced diet. Just like Calorie intake, your macro intake should reflect your individual needs and preferred diet.

  • Hey dietbetters! So today was the first day in more than a month that I performed a solid cardio session. Believe it or not, I actually found myself yearning to go on the stairmaster. ???? I went ahead and performed a decent 20 minute session at a steady level 8 prior to my weight training.

    I had decided to temporarily break from cardio exercising. At the time I was feeling extremely burnt out. I needed to give myself time to recover, reevaluate, and reestablish a routine. I definitely feel ready to reintegrate cardio exercise into my routine, but in an enjoyable way.

    On that note, I wanted to stress the importance of performing cardio exercise! Strength and resistance training has many benefits, but those benefits are secondary to the benefits of regular cardio exercise. As the name implies, cardio exercise exercises your cardiovascular system. This basically means your heart and lungs become more efficient. But the benefits of cardio exercise are not limited to your cardiovascular system, cardio exercise can improve your mental health and clarity, energy, cholesterol, and sleep.

    There are many ways to perform cardio exercise- it's not only limited to running. Cardio exercising can be stair climbing, rowing, cycling, hiking, dancing, battle roping, power walking, HIIT, and etc. Whatever you enjoy that gets your heart pumping, blood flowing, and breath heavy! You should aim to perform 2-3, 20-30 min cardio sessions per week. And REST in between!

    So what's your favorite form of cardio exercise?

  • Now that we know how many Calories we need, time to learn about where those Calories should come from. There is debate about which diet is best, but the fact is, there is no universal best diet. We are each individual with differing internal and external circumstances. The best diet for you should meet your specific needs, be fulfilling, and be maintainable. From keto to vegan and everything in between, the thing that will matter most is the quantity and quality of the food you are eating.

    Quantity will encompass portion control and overall Calorie intake, but what about quality? I mentioned before that there is no good or bad food, but there is nutrient dense food and calorie dense food.

    There is no denying that our bodies function best with whole, minimally processed foods. These foods promote healthier weight loss and management. Whole, minimally processed foods are naturally nutrient dense and have a lower calorie content. They provide vital nutrients your body needs. These include lean proteins, healthy fats, vegetables, fruit, whole grains, and etc. These foods should make up 80-85% of your daily Calorie intake.

    Opposite to whole, minimally processed foods are heavily processed foods. These foods are calorie dense and have a lower nutrient content. In other words, they do not do much for your body aside from provide an excess amount of Calories. These are your shelf stable foods, frozen foods, fast foods, and etc. While it is not necessary to exclude these foods from your diet, these foods should make up no more than 15%- 20% of your daily Calorie intake.

    So if you have been logging your food lately, review your log. How much of your food is nutrient dense, and how much would be considered Calorie dense? Can you make an improvement on your intake of nutrient dense foods? Feel free to share your findings below!

  • Hey friends, we are already into to our second week of DietBet! I'd love to know how your first week went. What changes did you incorporate into your routine and how has it affected you thus far? Remember you are welcome to share about your journey here... any meals, workouts, accomplishments, setbacks, and etc. Feel free to ask me any specific questions as well, or things you'd like for me to post more about. 😊

    So last week I shared how to calculate your BMR and TDEE. Your TDEE is your estimated total daily energy expenditure, and as you may recall, this number is equal to the amount of Calories you need to intake daily to maintain your weight. Now in order to gain or lose weight, your Calorie intake will need to be greater than or less than your TDEE.

    It is generally understood that one pound of fat is equal to 3,500 Calories; therefore, in order to lose 1 pound of fat a week, you would need to create a 3,500 Calorie deficit each week. This would equal to a 500 Calorie deficit per day. So based on your TDEE, you will subtract 500. The resulting number will equal your new daily Calorie need for a 1 pound per week weight loss.

    As a note, it is not recommended to exceed a Calorie deficit of 1,000- or a 2 pound per week loss. A Calorie deficit exceeding 1,000 per day will place you far below your energy need, thus NEGATIVELY IMPACTING YOUR HEALTH.

    Lastly as a reminder, as you progress through your journey -and life in general- your TDEE will change. Review and adjust your Calorie need often as you see fit.

My first week I gained 3 lbs...period and Halloween were not kind to me. But now I’ve lost that weight and 2 more lbs. so I’m heading in the right direction. Charting my meals has been super helpful to keep me accountable this week

Get ready for the final weigh in! Once the game ends tonight at midnight PST, you have until 11:59PM PST on Nov 25 to submit your final weight. If you're a winner, you'll be asked to submit photos and will get a new weigh-in word when you visit the weigh-in screens.

Submit early to make sure your photos are accepted, and remember - don't eat that cupcake until you get an email that your photos are approved! (If you don't get one, check your spam folder.) You must have an approved weigh-in in order to be declared a winner.

The game will finalize 24-36 hours after all weigh-ins have been submitted. Good luck!
