You can lose 1-3 kilograms in the first week of doing OMAD. Reduction of carbohydrates and sodium intake from diet triggers the body to release extracellular water. That said, any changes on the scale in the first week are due to the water loss (2).
That said, intermittent fasting in general has proven to be an effective weight-loss method. The typical weight loss is 7 to 11 pounds over 10 weeks. It can improve your metabolism. In adult men with prediabetes and obesity, a 6-hour period of eating followed by 18 hours of fasting improved their blood sugar levels.
Other studies have shown that eating one meal per day may increase fasting blood sugar levels, delay the body's response to insulin, and increase levels of the appetite-stimulating hormone ghrelin, compared to eating 3 meals per day. This can lead to extreme hunger ( 10 ).
Unintentional weight gain occurs when you put on weight without increasing your consumption of food or liquid and without decreasing your activity. This occurs when you're not trying to gain weight. It's often due to fluid retention, abnormal growths, constipation, or pregnancy.
OMAD is a very effective way for losing weight quickly, and with few (if any) negative side effects. In fact, you will likely see a decrease on the scale within the first few days or week of starting this type of intermittent fasting protocol.
And eating small amounts of food won't “shrink your stomach” either. The only way you can physically and permanently reduce your stomach's size is to have surgery. You can lose overall body fat over time by eating healthy food choices, but that won't change your stomach size.
OMAD Fasting Results – OMAD Weight Loss expectations
The OMAD weight loss results 1 week indicate around 2 kg of weight loss. An average weight loss from any other diet plan is around 1 kg on average. Some obese people have also lost about 5 kg of their body weight in their OMAD diet results of 1 week.
To lose 10 pounds in one week, you'll need to burn between 3,500 and 5,000 calories more than you consume each day by restricting your diet to small portions of nutritious yet low-calorie foods, and significantly increasing your aerobic exercise with interval training, sports, and other vigorous activities.
Fast weight loss, such as losing 10 pounds in a week, is possible — but it's usually not worth it. In fact, it could be detrimental to your physical and mental health. In reality, plans and programs that promise rapid weight loss or extreme results are best avoided.
The Military Diet is a short-term, calorie-controlled meal plan that claims to help you lose 10 pounds in one week. The diet involves eating a set calorie-restricted menu for three days, followed by four days off the diet, in which you're advised to eat in moderation or follow a less restrictive, low-calorie meal plan.
But on average, you should lose 10 pounds in exactly 5-6 weeks for a healthier and more achievable estimate. This means that you lose around 2 pounds per week, which is in line with the CDC's recommendation for safe weight loss at a rate of 1–2 pounds per week, a sustainable goal.
Dieting is essential for weight loss, but exercising is equally important. OMAD works best when combined with strength training exercises. Exercising while fasting boosts your performance and overall strength.

Any type of intermittent fasting, including OMAD, won't necessarily slow down your metabolism on its own. However, anytime you restrict calories, your metabolism will gradually slow down to try to match your energy output with your energy intake.
Many people complain that they gain weight around the holidays, but you'll be happy to know that you can't really gain weight from a single meal or day of overeating.
Eating once a day slows down your metabolism.
"If you go long periods of time without eating, your metabolism actually slows down to hold on to energy," Brenda Braslow, RD, MS with MyNetDiary. "It can defeat your efforts to cut back on calorie intake."
Set a designated meal time and stick to it. Many people who follow the OMAD diet try to eat their meal in the middle of the day. Instead of eating first thing in the morning, have something to drink and then get your day started. If you stay occupied for several hours, you will not even have time to think about eating.
No. While OMAD might be able to help with weight loss, it is definitely not a diet made for weightlifting and muscle gain.
The OMAD diet is a form of intermittent fasting where you eat in the same 1-hour window each day. It's recommended you consume your one meal after your most active part of the day. Children, elderly, and people with health conditions like diabetes should not try the OMAD diet.
While the fast may be brutal, many people still find a lot to like about OMAD. You can eat or drink pretty much whatever you want (even pizza, burgers and beer), and as much as you want, as long you do so during your scheduled mealtime.
The Pros of OMAD
Increased human growth hormone (HGH) levels: Fasting increases levels of this hormone that helps build muscle and burn fat. Lowered inflammation levels: Fasting is known for its ability to reduce inflammation. When you aren't eating, your body can divert its energy towards repair.
To put it bluntly: "Women and men of average height need to gain or lose about about 8 and 9 pounds, respectively, for anyone to see it in their face, but they need to lose about twice as much for anyone to find them more attractive," lead author Nicholas Rule told Medical News Today.
"By the time you hit 10 pounds, your jeans will feel differently, absolutely," Blum says. "Just a little looser. Theoretically, 10 pounds is considered one size." Once you get past that first couple pounds where you might not be able to tell, Blum says, you really do start to lose body fat.
We recommend losing no more than 1 to 2 pounds per week for sustainable weight loss, which means you could potentially lose 10 pounds in five weeks. However, a more realistic timeline is 10 to 24 weeks, since most people don't have hours to devote to walking every day.
