You decided it was time to cut back on sweets, maybe go to the gym a little more often … but what day is the best time to start a diet? Most people choose Monday, the first day of the month, or another special day to change their lifestyle. So, are these the best days or is there some unused secret day we should be aware of? Keep reading to find out!

The best day to start a diet

Ready to start a new habit and actually stick to it? Choose one of these days!









No matter how cliché sounds, studies show that Monday may be the best day to start a diet. Do you know that “a new week, a new self”, “I can take on the world”, feeling that you sometimes get? Scientists call this the “new start effect,” and you must use it to start your diet! Use this energy to diet, clean your pantry, or head to go to the gym. People who start diets on Mondays are among the most successful in maintaining their healthy habits.

The same feeling appears at the beginning of the month, so if the first is just around the corner, it is also a good candidate for the first day of your new habits!

The only caveat: if you fall from the wagon, do not wait until the next Monday (or the 1st of the month) to start again. Each meal is a new chance to make a healthy choice, and every day is a new opportunity to start all over again. If you ruin it once, don’t throw away all your work. Just start again with your next meal or the next morning!


Sunday enjoys the same “new start” benefits as Monday, but you probably have a bit more time. If you are planning / preparing one of the things you need to improve your healthy lifestyle, this is may be the day for you. If you start your new habits on a day when you don’t need to work, you will have enough time to go to the grocery store, prepare food or plan your new daily routine in the gym. If you really need to redefine many aspects of your lifestyle, consider Sunday your first day.

Day after your birthday

The last effective day “start from scratch.” The best day to start a new diet is the first day of the new year for you – the day after your birthday or anniversary is a popular choice. Some people prefer these annual events to a random week or month because it makes the goal more specific. You may have heard about people starting in these days when they were the year before large numbers, such as 40 years, or the celebration of their 10 th wedding anniversary.

With event / program

In addition to starting from scratch, another group of dieters who have above average success rates when following their plans are people who start with a group / for an event. This is true for people who are trying to become healthier in other aspects of their lives, such as quitting smoking. So, if the task of “getting better” is being carried out in your school or workplace in the near future, consider registering! In addition to a specific time frame for goals, the competitive nature of these problems helps many of us resist the temptation and continue to insist.

The worst day to start a diet

Now that you have some great options for a better day to start a diet, you should also know that there are certain days when you should not start a diet.

If this is one of these days, wait until the start of next Sunday or Monday (of your choice).


Studies show that people starting a diet on Tuesdays have the highest dropout rates on Friday that week. Therefore, if you missed Monday, you’d better wait until the next Monday than start a new, healthier lifestyle on Tuesday.

New Year’s Day

This may come as a surprise. You think: “… but you just said that a new start was the key to success, and the New Year is definitely a new start …”? Well yes, it is. But we historically have unreasonably high expectations for the New Year, which leads to a higher dropout rate. It is better to start from the other at the beginning (or from the beginning of the week), when there is not so much pressure to change everything. In the end, a slow and steady wins the race!

Diet menu

After you have chosen a day to change your life and become healthier, you also need to make a weight loss grocery list and find suitable slimming recipes. If you choose a good day to start a diet, it does not mean that you continue to eat chocolates and cakes and lose your weight.

There are sooooo many diets. All what you need to do it is just drive thru diets and choose the best one.

Nutritionists recommendations:

Always remember: whatever diet you choose – low-calorie, vegetarian, Mediterranean, buckwheat, kefir or any other, try to lose weight gradually. There are many ways you can do this, without cutting calories too much. That is why you need to make a weight loss graph and the plan diet and know how much weight should be reduced in a week, a month, or six months. You could:

  • Cut back on portions.
  • Figure out how many calories you get in a usual day, and trim back a bit.
  • Read food labels to know how many calories are in each serving.
  • Drink more water, so you’re not so hungry.

Whatever method you use, you’ll need to favor good-for-you foods like vegetables, fruits, whole grains, and lean protein so you keep up good nutrition. Working with a dietitian is a good idea, so you make a plan that covers those needs.  And remember, the best diet for weight loss is a sport, such as crossfit.
