If You Want to Lose Weight, You Have to Start Eating!

One of the most common comments or concerns of those starting flexible dieting is about the amount of calories or macros they are expected to eat.

Here’s one such comment:

I’m 24, 175 cm (5″10), 224lbs. I am fairly active (I workout 4-5 times a week) and your calculator puts me at 2033 calories a day, 154c, 227p, and 56f. I just think 2033 calories is fairly excessive and I’ve been on diets all my life and have never passed the 1300 calorie range as I am considered overweight.

It can seem really strange to eat so many calories when you’ve been told all your life that the only way to lose weight is to follow a low calorie diet.

But, for many, eating more is actually the key to losing more. Here’s why.

Why You Must Eat More to Lose More

In the above example, this woman was accustomed to eating 1300 calories. She would probably burn about 400 calories at the gym, which would only leave her 900 calories to fuel her bodily processes and general movement on exercise days.

According to our calculator, her sedentary calories are 2218 just to maintain her current weight. Therefore on exercise days she is putting her body in a 1318 calorie deficit.

Our basic understanding of weight loss principles would say, “wow, she should be at her target weight in no time!” but, the body doesn’t quite work that way unfortunately.

Your body is a very complex machine and its goal is survival, even at the cellular level.

So what’s the body to do when it needs 2218 calories, but you are only giving it 900?

Starvation Mode

A few days of drastic calorie deficit are fine and cause no changes, but for those that consistently eat at dangerously low calorie amounts the body switches into a conservation state or what some people call starvation mode.1

Our bodies are very clever and we still don’t yet fully understand all of the ways it can survive when placed in stressful situations.

This explains why some people who have been stranded at sea can survive for months on practically nothing. The body begins to slow down the metabolism in an effort to maintain homeostasis in light of a drastic calorie deficit.

A similar thing happens for extreme dieters. The body slows things down, slows the burning of fat, and actually begins to breakdown muscle tissue for energy especially if the dieter is also engaged in weight training.

Muscle Cannibalization

Muscle Cannibalization is simply when your muscles are broken down by the body and used as fuel for other parts of your body.

Drastic calorie deficits can cause this as well as not eating enough protein. Your body can break down one muscle group to build and repair the group you just worked out and then vice-versa later in the week when you work out the other muscle group.

One study showed that instead of fat loss occurring and then muscle loss during starvation, they both can happen in parallel to each other.2,3

To prevent this from happening a dieter must eat enough calories and enough protein to prevent this from occurring.4 Dieters want extra energy to come from their fat reserves, not their muscles or they’re defeating the purose.

The Solution is To Eat!

Unless a dieter is morbidly obese and under the direct care of a physician, he/she should never have a calorie deficit of more than 400-500 calories or 20% less than their TDEE calories with the calories burned during exercise factored in.5

For those that are already pretty lean, but just have 5 pounds to lose, calorie deficits can be even smaller.

So, make sure you are eating enough to support your bodily processes and the growth and activity of your muscles, but not too much that your body won’t burn a small amount of its fat reserves each day to make up for the slight deficit you are in.

It can be really challenging for some dieters to eat more, especially if they have been doing low calorie diets for a large portion of their lives. It can also be challenging for people to eat the amount of carbs recommended with flexible dieting especially for those that have had “carbs are bad” drilled into their heads for so long.

It’s time to start eating again and come into a better relationship with food. Slow and steady weight loss is the goal with flexible dieting and this, unlike other diets, is sustainable over the long-term because you are able to eat and not feel deprived.

Here’s a comment from someone who started to eat again.

Thank You so much! I’ve been on it for a week. I meet my macros, but having a hard time getting all the calories in, I’m not eating under 1300 anymore but always end up around 1500 at most – it’s not much difference but my body feels great; I recover much better and I am eating more carbs than before but not yet the 205 recommended. I’m still at 60% this week but next week I’ll amp up to a 70%, my body has already started to change.

Manage Expectations

I also want to express the importance of managing expectations when doing the flexible diet or any diet.

There are many different body types and most people may never be able to achieve the body that has been Photoshopped on the cover of our fashion or fitness magazines.

For women, nature is actually working against the quest for a low body fat percentage. A woman’s hormones are constantly preparing the woman’s body for childbearing and this means a healthy layer of body fat.6 Just look at the body fat percentage differences among men and women.

So, focus on getting healthier by eating nutritious food, eating enough food, and being more physically fit because usually only those that get paid to look like ultra-ripped athletes actually have the time and resources it takes to look that way.

In closing, I can’t express the importance of working to change your low calorie and low carb mindset and begin eating again. If you want to break free from a slow metabolism and break the weight loss plateau then you have to give your body enough fuel to leave the launch pad.

    Everything is a Lie….Lol….Growing up I’ve always heard that calories and carbs are BAD, but I remebered that at one period of time I did gymnastics and dances that I had learned but afterwards I would eat A LOT……I realized that at that period of time that was the smallest Ive ever been and Im an athlete so I now know that I need to eat MORE not LESS

        You are at a healthy weight for your height and you shouldn’t be cutting calories since you are also growing.

    I’ve perused a few people go straight to their TDEE though others gradually get up to their TDEE and after that start a slice in the event that they need to get more fit. Will I stun my framework with a major increment in calories on the off chance that I have been under eating for a short time.

      If someone has been undereating for some time, they may gain a pound or two in the beginning. But this usually corrects itself once the person’s metabolism starts to rev back up.

    Hi, I’m a 47year old male. I weighed 239lbs in January and now in June I’m 201lbs. What I did was cut calories and hit the gym when I could. My waist reduced by 6 inches but to be honest I lost 5 of those inches in around 3 months but now not much else comes off my waist but my weight was still dropping which leads me to think I’m losing muscle as well. Any ideas as to how to reduce my waist as I don’t have any fat of note anywhere else…thanks

      Great job on your weight loss. How many calories are you eating and what’s your exercise like? There’s also visceral fat to consider. It’s fat that surrounds our internal organs.

        Thanks Ted.
        I eat around 2200cals but some days will be less. I try get to the gym at least 3 days a week but some weeks I can only go only go once due to work and family commitments. I do weight training ie squats.barbell row, overhead press and bench press. I also do work on machines as well. I think I need to up my calories through protein as I don’t want to lose muscle mass as I think this is what is happening…would you agree?

    It is always said you become what you eat. So, eat healthy, green leafy vegetables and fiber rich foods that have no calories and carbs. Be the healthiest version of yourself to enjoy your life to the fullest.

    Hi, I am 22yrs old. First and foremost, I am not a body conscious but I am fond ond doing work out but when I start working I noticed gaining more weight and not I am obese.
    How can I lose weight in a fastest way? Is there any other method?
    I am planning to have my weight back same as before?
    Is it possible in a fast way?

      When you start working out, you gain water weight because exercised muscle retains water. Secondly, when you workout muscles become denser which also adds weight. Thirdly, exercise increases the appetite, so if you aren’t aware of what your TDEE is or how much you should be eating, you could be overeating. You can calculate how much you should be eating here

      I have a hard time losing weight, so I have been cutting myself down to practically nothing to lose weight.

    I’ve been trying the “low – fat don’t fret the carbs” diet for years, including while training 12 hours per week for triathlons (800 miles per week bike 10 miles per week running and 2k per week swimming). It doesn’t work.

    Low fat diets are a scam. If you eat white sugar, white flour and a lot of starches you’ll get fat.

    Yes starvation mode is real, yes caloric restriction will cause it.

    Try eating ~1 gram protein for every pound of lean body mass, just enough carbohydrates to meet your weight goals and enough fat to feel satisfied between meals. It works. Your carbs should come from green vegatables first, beans and whole grains next and a bit of pasta for variety and some sweets 2x per week just for fun.

    High carb diets are BS. Sure they “can” work if you want to feel hungry the rest of your life.

    After reading the article I noticed that it says a person will go into starvation mode if he/she starts eating way too few calories. I was under the impression that this usually happened when a person is on a full-on fast, and starvation mode doesn’t usually happen until 2 to 3 days after staying on the fast. Its not good to fast and go to the gym, but it stands to reason that if one does cardio the metabolism isn’t given a chance to slow down. Hopefully people will NOT fast while going to the gym. Reducing calorie intake, such as with intermittent fasting, should not cause starvation mode as far as I know. I have to disagree that eating more can help a person lose weight.

      The more I eat the more I lose weight. I am a perimenopausal woman, and I can attest to the truth of what’s written in this article. Extreme calorie deficits over years put more than a hundred extra pounds on my body even when I was eating as low as 500-750 calories a day, I was rapidly gaining weight, and it wasn’t until I started eating significantly more calories that my body was able to start releasing the excess weight. When I first started eating more, it took nearly 4000 calories a day for the weight gain to stop and begin to reverse itself. I now eat about 2200 calories a day and steadily drop 3 pounds a week on average, without exercise beyond a daily walk.

        You are lying about how much you were eating. If you were eatting that little a day and working out you were not gaining weight. You’re only telling half truths. Also there is no way you were eating 4000 calories a day for the weight gain to stop. Unless you were just eating shit food. You’re not telling the honest truth

    This is really useful information and seems to be happening to me now. I’m a 6 ft 1″ male and was 288 pounds at the beginning of April last year. As of last week, I’d got down to 240, through a mixture of diets but mainly low carbs and alcohol, no sugar and calorie counting.

    Over Christmas I put on around six pounds but managed to lose most of it in the following week. Now, although I’m really proud that I feel in total control of my eating, as it’s a new year I wanted to go more extreme as I still have a way to go to reach my target weight.

    So, a week ago I restricted myself to under 800 calories a day to get into fast fat burning mode, I weighed myself today and I’ve only lost 2 pounds. I really don’t get it and it’s so frustrating but perhaps it is just my metabolism adapting. As of today I think I’ll slowly up my intake. Sorry for the long post, I just felt the urge to share.

      Slow and steady wins the race. It can be tempting to cut way back for faster results but in the long run 1-2 pounds per week is what you want. Great job on your progress so far.
