I’ve wished to lose 10 kilos (~6% of physique weight) ever since I began Monetary Samurai in 2009. I’ve come shut, dropping 5 to 6 kilos in some years, however by no means fairly hitting the double digit objective. Because of this, for greater than 16 years, I failed to perform one thing that ought to have been easy, particularly for a supposedly rational economist and private finance nerd.
There have been even moments after I thought-about deliberately gaining plenty of weight simply to make shedding 10 kilos simpler. The concept felt much like racking up a ton of bank card debt to get pleasure from life to the fullest, then celebrating as soon as it was all paid off. I noticed folks do that on-line and get praised like heroes.
As an alternative of intentionally gaining weight, I ultimately determined it was more healthy to only drop a few pounds. And surprisingly, all it took was lastly making use of two financial ideas: discount and substitution. As soon as I did, the load got here off in six months.
The Primary Financial Precept of Discount
As the value of rises, the amount consumed tends to fall. This relationship is clearly illustrated by the basic supply-and-demand curve.
If every meal prices $25 and I’ve $100 to spend on meals, I can purchase 4 meals. If the value per meal rises to $33.34, that very same $100 solely buys three meals. With a set price range, the rational shopper should scale back consumption by about 25–30 p.c.
The place we get into hassle financially is ignoring this precept. As an alternative of adjusting conduct, we pay $134 for 4 meals, take in the upper price, after which complain about meals inflation.
A extra constructive response is to make use of increased costs as a forcing perform to eat much less. Fewer meals out may also help us keep inside price range and, in lots of instances, enhance our well being as nicely. Decrease spending and higher self-discipline is a win-win final result.
Sure, combatting inflation is simple however not straightforward. As buyers, we have been in a position to make good-looking returns in recent times, thereby making it simpler to splurge on meals. Nonetheless, as a rational economist, you alter your conduct if you wish to change your final result.

We Ought to Have Consumed Much less Meals Throughout The Pandemic
Based mostly on the straightforward financial precept that increased costs ought to scale back consumption, I ought to have misplaced a ton of weight through the pandemic.
As an alternative, beginning in 2020, our meals spending climbed quickly as we ordered extra supply. On the time, it made sense. Supply saved time and lowered publicity threat, particularly since our daughter was born in December 2019 and had a still-fragile immune system.
The issue is that meals supply sometimes prices about 20% greater than selecting up the identical meal and roughly 50% greater than cooking at house. With a new child and a three-and-a-half-year-old, we justified the premium as a mandatory time saver.
5 years later, we had been nonetheless ordering supply usually. Not solely is it costly, however restaurant meals can also be usually much less wholesome, with increased ranges of added sugar and salt.
The Catalyst To Lastly Begin Dropping Weight: Much less Cash
To drop a few pounds, it helps to have a catalyst. Mine was spending 5 weeks with my mother and father in July 2025. My dad, who’s about six ft tall and weighs roughly 155 kilos, referred to as me chubby. Thanks dad. I fired again that he ought to placed on some weight and muscle.
However deep down, I knew I may stand to lose some weight. On the time, I used to be 5 foot ten and weighed 172 kilos. There’s nothing like going to Hawaii and having to take your shirt off on the seaside to make you confront extra weight. If you’re now not making an attempt to draw a mate, the pure tendency is to let your self go as a result of you have already got one.
As a result of we stayed with my mother and father, we saved at the very least $20,000 in lodging prices. Initially, I solely had meals and transportation bills to fret about. That modified as soon as I made a decision to rework my mother and father in legislation unit. What I believed would price $25,000 ended up costing $41,000. It was essentially the most cash I had spent in a four-week interval since transforming a previous house from 2019 to 2022.
As I watched the payments pile up, I grew to become conscious about each price round me. When bills rise, money move out there for every thing else shrinks. And one of many few really versatile bills left was meals.
Because of this, I deliberately determined to spend much less on meals to enhance money move. For instance, as a substitute of spending $25 for an additional container of poke from Contemporary Catch, we made due with much less. The humorous factor is, in the long run, my mother and father ended up footing 85% of the rework invoice. I simply did not count on them to, which is why I lowered my bills.

A Cautious Inspection Of Our Meals Finances
After we returned from Hawaii, I lastly examined our meals spending intently and was surprised. We had been spending round $3,500 a month on meals for a household of 4.
Though I handle our investments and generate supplemental retirement revenue by this website and e-book writing, I don’t actively handle our family bills.
In my head, I believed we had been spending round $2,500 a month on meals. Inflation that accelerated after 2021 modified every thing. Although headline inflation has moderated, our meals prices are nonetheless roughly 40 p.c increased than they had been 5 years in the past.
Mentally, I used to be caught in a a lot earlier pricing period till I confronted the precise numbers. Inflation has an effective way of sneaking up on us.
Including Substitution To Lose Weight
Anchoring to outdated value reminiscences is why all of us ought to conduct a deep monetary overview at the very least every year. What we bear in mind is commonly disconnected from current actuality.
This is identical anchoring mistake many older generations make after they say issues had been low-cost again of their day and that working more durable was all it took. They underestimate the compounding affect of inflation relative to wages.
As soon as I understood our true spending, my spouse and I created a month-to-month meals plan. Our goal was to return to $2,500 a month and save $1,000 a month whereas consuming more healthy. That meant consuming much less, but in addition substituting.
The largest substitution: going from meals supply to extra home-cooked meals.
Residing in San Francisco, a high three meals metropolis within the nation, makes this more durable. We construct the expertise that makes meals supply handy. We’re additionally surrounded by lots of of fantastic eating places throughout each delicacies possible, all deliverable inside an hour.
In actual fact, I not too long ago found a restaurant referred to as Khao Tiew that serves the very best khao soi I’ve ever had. Sadly, when you add boneless beef quick rib and tax, the dish runs about $28 for pickup. So for now, I’ve changed it with $1.49 prompt ramen noodles and name it a lesson in self-discipline. Substitution child!

Write Out Your Causes For Wanting To Lose Weight
After operating by your price range and deciding how a lot to cut back and what to substitute, it is lastly time to write down out the the explanation why you wish to drop a few pounds. As a result of after getting a why, you are able to do virtually something.
My causes are:
- Enhance money move by $1,000 a month as I put together for harder instances forward attributable to AI.

The Last Monetary Kick within the Rear to Lose Weight
By mid-October, three months in, my weight dropped from 173 kilos to 168 kilos. I felt good in regards to the progress as a result of I used to be now not simply shedding water weight. It felt actual.
Then Enterprise Insider got here by to interview me about saving cash whereas elevating a household. Once I noticed myself on digital camera, I felt newly motivated to maintain shedding pounds. The saying is true: the digital camera actually does add 10 kilos.
After the video got here out, I may all of a sudden empathize with actors and celebrities who obsess over health, weight-loss medicine, beauty procedures, and excessive diets. When your picture impacts your livelihood and future alternatives, the strain to look your greatest is intense and comprehensible.
The expertise additionally bolstered my need to not pursue video to not fall into the entice of exterior validation. So it’s again to writing and podcasting for me, the place the main focus is on concepts relatively than appearances. However if you would like motivation to drop a few pounds, movie your self and watch it.
Thank Goodness For Larger Meals Costs
If meals costs had been falling, meals consumption would logically rise. Good meals is tough to withstand. However after I watched my favourite steak on the grocery store go from $28 a pound to $32 after which $39, I finished shopping for it. First I substituted with $12 cheeseburgers. Then I started lowering the consumption of meat altogether.
As supply charges and menu costs climbed, opting out altogether grew to become less complicated. Meals that after price below $85 for our household of 4 now routinely exceed $140. At that time, rice porridge with hen and cabbage for $15 overlaying two days sounded nice.
Now that I’m used to a flatter abdomen, I’ve no need to return. My endurance on the court docket has improved and I really feel fitter total. As Steven Tyler as soon as stated, “nothing tastes nearly as good as skinny feels.”
Though paying extra for meals is disagreeable, I’m oddly grateful. For too lengthy, I lived comfortably with out scrutinizing my meals spending and ate no matter I wished. That is the issue with residing in America given there’s an abundance of every thing.
By consuming much less, I not solely misplaced weight but in addition improved my monetary self-discipline. Possibly I’ll even attain 155 kilos sooner or later, like I used to be in highschool, and stay to 80 like my dad.
Who am I kidding? 155 kilos is just too gentle. I’m joyful staying round 165 kilos, plus or minus two, for the remainder of my life. Battle on!
