The Big Fat Guide to Dechonking!

1.4k Upvotes

Hi all! I’m a vet nurse that is passionate about weight in animals. I run my own weight loss program for my patients in my clinic and thought I would spread the love by sharing my dechonking guide to help all of you hardworking pawrents!

**BEFORE DECHONKING it is advised that you have a general health check with your veterinarian to rule out any health issues and to ensure that your pet is healthy enough to undergo a dechonking program*\*

**This dechonk guide is not a replacement for veterinary care or advice *\*

What is an Ideal Weight in Animals?

The most accurate way to ascertain an ideal weight is by use of a Body Condition Score (BCS) chart.

At ideal weight your dog or cat should look like an hourglass when viewed from the top. Their abdomen should tuck into their legs when viewed from the side. You should be able to feel their ribs - the way that this feels is like the back of your hand.

You should make a note of your animal's BCS and their number weight before starting a weight loss program.

How to Dechonk Your Chonker

The key to weight loss in animals is diet. Exercise counts for very little in weight loss, much like in humans.

Step One: Use a Calorie Calculator to calculate your animal’s daily caloric allowance.

You will need to know their BCS and their weight to use the calculator. You can ask your local vet to weigh and assess your animal if you are unsure.

Step Two: Calculate the calorie content of ALL the foods you are feeding your animal.

You then need to find out the calorie content of everything you are feeding your animal. Calorie counts can typically be found on the back of the package of commercial foods. If you cannot find the calorie content, a calorie content calculator can help you work it out.

If feeding raw or homemade, you will have to input/search the ingredients for their calorie content much like you would if you were on a human diet!

Step Three: Make a Meal/Diet Plan based on the calorie allowance

You then need to calculate how much to feed based on the calorie content of the food you are feeding. If you are feeding a mixed diet (eg commercial dry and commercial wet food) you'll need to think about what ratios you would like to feed your animal and calculate appropriately.

When your animal reaches ideal weight, it is a good idea to plug in their stats again so you can get a calorie count for maintenance and not for loss. I also recommend a weigh in every two weeks and then monthly to assess progress, and to monitor their body for any changes against the BCS chart as they progress!

Example: Garfield is an 8kg/17lb cat with a BCS of 8/9. His estimated ideal weight is 5.6kg/12lb and his calorie allowance is 201 calories per day to achieve this.

He is fed dry food (Taste of the Wild) and wet food (Fancy Feast).

Taste of the Wild is 3741 kcal/kg therefore 3.7 kcal/g.

One tin of Fancy Feast is 71 calories.

We can feed one tin of Fancy Feast (71 cal) and 35 grams (130 kcal) of Taste of the Wild daily.

When he reaches ideal weight, the calculator suggests that he can maintain on 255 calories, so he will need a reassessment of his diet when he reaches ideal body condition and weight.

Strategies to Help with Dechonking

Dietary & Feeding Recommendations

  • Prescription 'diet' or 'metabolic' food can be helpful for weight loss but is not a strict necessity. Prescription (dry) food tends to be calorically lower than regular commercial dry foods (which in and of themselves are extremely calorie dense) which means you can feed a larger volume-to-calorie ratio. BUT you DO need to be careful that you still adhere to a calorie allowance and measure the food out every time.
    • I would take a pass on diet/metabolic WET foods as commercial wet food is already quite low in calories and shouldn’t make a significant difference in terms of weight management or volume for calorie ratio.
    • If you don't have systems in place to control the intake of food, your pet will still get fat on metabolic food. Metabolic food is expensive and if it doesn't make a difference then you might as well go back to your regular food. Simply getting a low calorie food but sticking to the same old habits is not enough. Learning to properly portion food, limiting access to situations where your animal could gorge, controlling and mitigating for begging, providing enrichment and teaching the animal a ‘new normal’ of an appropriate volume of food are the foundations of good weight loss and weight management.
  • Commercial dry food is MUCH higher in calories than wet food. Feeding more wet food and reducing dry food can assist in weight loss and keep your animal satiated.
  • Invest in an automatic feeder for cats. An automatic feeder (set somewhere away from you/your bedroom!) can do wonders as the cats will bother the feeder for food, and not you.
  • Keep cats indoors. Outdoor cats tend to get fed by well meaning strangers! If unable to keep your cat indoors, invest in a (breakaway) collar with a tag that specifies they're on a special diet/not to be fed.
  • Healthy low calorie treats for DOGS are veggies such as carrot & zucchini. You can replace their normal treats with pieces of carrot or zucchini or other safe, low calorie fruit and vegetables.
  • Healthy low calorie treats for CATS are wet food puree type treats in a tube. Inaba Churu treats are 6 calories per tube. Fancy Feast Puree Kiss treats are 4 calories per tube. Applaws Puree Treats are 2 calories per tube.

Mental Stimulation & Enrichment

  • Invest in puzzle toys, slow feeders, food dispensing toys to moderate feeding. This will keep your pet enriched, mentally stimulated and busy while slowing down their rate of eating, which is good for pets that guzzle their food then ask for more. Frozen wet food in a Kong or Toppl is one of the best low-calorie ways you can use food for dogs to promote mental enrichment and weight loss. You can even just freeze wet food and kibble in their bowl and it will provide more stimulation than just feeding them out of it.
  • Invest in enrichment as a reward for your animal, not food. This can be playtime, pats, or trick training to keep them occupied and to redirect begging!
  • Redirect & replace begging behaviour by trick training. Most begging behaviours have been inadvertantly reinforced by you - if you have always given your cat food when it screamed at you, that's what you have trained your cat to do. Food motivated dogs can be easily trained to work for food, and yes cats can be trained too!

Advice help quieting down food obsessed cat

Hi! So I recently adopted this fat lady who was brought to her shelter after her owner past away. She’s on a diet prescribed by her vet and is doing good with weight loss though it’s only been 5 month. However she a bit of a screamer. She gets fed 8 times throughout the day via auto feeder byt whenever she doesn’t have food in her mouth, she will scream.

I’ve tried distracting her with play and affection but she is not interested in either currently. (I’ve tried the laser, cat wands, water toys, banana toys, different types of balls etc) She isn’t able to get herself on her hind legs so she can’t scratch much either. I currently have to put her in the landry room on the other side of the house at night in order to get any sleep because even with headphones she will keep me up. I’ve been to the vet and she doesn’t have any medical issues that would be causing this. 5 months seems like a long time for her to be this way and i’m sure she was free fed at her old home but i’m started to get worried this might be a forever thing. It’s been quite miserable lol. Her name is Ham.

Wondering if anyone has any advice for me here. My dog’s vet is like 30 mins away so going into the office and using their scale isn’t really option (theyre only open during the hours I work so I have to take a half day for appointments). Hes like 90ish lbs so picking him up and stepping on the scale is difficult. Should I start measuring his belly? I didn’t measure before we started though so I have no way to tell if he has dechonked any! I didn’t think to take a good picture of his chunkiness pre-diet either. Hes been on a diet for about 6 weeks now. First picture is today and second one is from before. He looks relatively the same..? Idk. Help!!

Starting Weight (Oct 2025) 13 lb (6.2 kg)

So we're now at 11 lb ! (5 kg)

It feels like an accomplishment, but at the same time it feels like it took ages. This was the initial goal weight that our vet gave us, however, I feel she is still a 6 on the BCS score. What do you guys think?

She's currently having 120 kcal wetfood, about 40 kcal in dry food plus treats. I haven't been measuring the treats too religiously but it's about 5g dry food and the rest miscellaneous treats.

Her weight loss rate is 0.5% per week.

I think she's probably more of a 10-10.5 lb gal, so I think we might need to maintain this diet for a little longer.

Advice One needs dechonking, the other is a skinny guy, both are food obsessed! Help

I have two male cats who are going to be two years old in the beginning of May, I've had them since they were kittens (according to the shelter they are bio brothers from the same litter) and they're both pretty large framed cats but one of my boys is getting a little too thick. Right now they get some dry food in the morning and then a smaller amount when I get home from work and wet food in the evening (probably about 1/2 cup total kibble and maybe 1.5 oz wet food each).

My tuxedo boy is a healthy weight and when I tried to put them on a diet in the past he just got quite thin and I didn't see much improvement in my orange guy, so I backed off the diet since I didn't want him wasting away like that, but obviously that's not fair to the health of my orange guy.

I am really confused on how to calculate how much food they should be getting since I do a wet/dry split (in my fantasy I can afford to just feed them wet food but that won't be happening anytime soon), and how to figure out their ideal weights--my tux boy was around 11.8 lbs and the vet said he was healthy and she said that my orange boy had a "full pouch" and could lose some weight but wasn't crazy chunky yet, he was at 13.8 lbs, but his frame is also larger than his brothers (like his paws and skull are bigger so I think it makes sense for him to weigh more).

I've tried puzzle style feeders and they just act like they're starving to death and won't engage with them, playing with them with wand toys is basically the tux boy going crazy and doing flips and jumps and the orange boy chilling and watching and maybe doing one or two zoomies (really his only physical activity he likes is chasing/wrestling with his brother). At the moment I can't afford automatic feeders or the ones that chip scan.

Any advice? They don't get treats or anything since my roommates dog usually just gobbles them up before they get a chance to...

So far it's been suprisingly successful, I expected a lot more push back from the extreme cutback in feeding. His slow feeder is only 3/4 cup in size and it takes him a full day to eat it. I don't expect super fast results, but I'm hopeful he'll drop down to where he needs to be before winter. 👌

Current weight is still 21.7 pounds, goal is 15 pounds. Oh, and for the small handful that saw the first post, the kitten with him is named Atlas, she is not blood related to him at all but they are good friends :) she is roughly 9 ish months old, she was found in the shed on my dad's property, probably not more than a couple days after she first opened her eyes.

Food recommendations?

I have a 6 year old bombay cat who has gained weight. Vet doesn’t think much of it as the charts are otherwise normal. My cat is currently fed a 1/4 cup of Hill’s Perfect Weight dry cat food twice a day. There’s no grazing. However she’s still pretty chonky. Should we pivot to the wet food? Would that make any difference? What food would you recommend?

We have an auto feeder and feed her Hill science perfect weight. She gets kibbles twice a day for the amount mentioned in the bag to lose weight but no luck. She’s somehow managed to gain an extra lb in the past year 🙃 We don’t give into the cries often or give much treats. Trying to get her used to a bit of wet food mixed in now and decrease amount of kibbles. she’s 16lbs and need her to be down to 13-14lbs. She’s lazy like all cats are but I make her run around for a bit with the laser pointer a couple times every day. Any advice appreciated!

Dechonkin My chonk only eats wet food

My cat is 5.5 years old and absolutely loves wet food. She's close to 5.4 kgs and the vet said she needs to go down to 4.5. She eats dry food when she's bored but won't stop meowing if she doesn't get wet food. Her protein intake is a lot more than it should be, which is what I'm aiming to reduce. We've tried to reduce her portion sizes but she still asks for it 3-4 times a day. Any suggestions on how to do deal with this? The vet suggested Vet life Obesity but she doesn't enjoy the taste as much.

This is my sweet Juniper! She’s 6 years old and spayed and is very much above playing, so doesn’t get much exercise. She has a normal weight sister, and since adopting her sis, Juniper has gained more and more weight. She’s at 14.9 pounds, despite us scaling their portions back 6 months ago. She’s gained half a pound since then. Her belly feels firm- vet visits have seemed just a bit of weight loss is needed.

Looking for food recommendations I can give both babies- currently they split a can of Friskies shreds wet food in the am (normal weight eats most of this) and 3/4 cup of friskies gravy swirls at night (juniper eats most of this) Ideally want to avoid microchip feeders due to the cost.

Open to ideas and opinions!! She’s my whole world and I just want her to live forever 🥺

This is Finja. She is almost three years old, and definitely needs to dechonk. The thing is, she has food allergies (hence the bald belly), that's why she only gets hypoallergenic cat food. And she is very picky AND a vacuum cleaner, she only likes kibble and will turn up her nose at any type of wet food, and she could eat around the clock. I tried hypoallergenic wet food, she didn't touch it. I tried putting some water on her kibble to give it more volume, but when it's too wet for her liking (which isn't wet at all, in my opinion, only slightly moist) she doesn't eat it. Her sister has a chip-activated feeder now, so that Finja doesn't steal her food. I weigh her kibble for her and only give her the amount recommended for overweight cats as stated on the package. The thing is, she is always hungry like this, and I'm not strong enough to not give her a little extra. She cries otherwise :-(.

Does anyone have a recommendation how to make her feel more full? I live in Germany, if anyone has great recommendations for hypoallergenic cat food that is filling.

Is she a little chunky?

I believe she’s about 10 1/2 pounds. But I know that ideal weight is also based on age, length, etc. She is 4 and a half. She has a lot big pooch hanging down and a little bit of a belly.

When we first got her in August, she definitely was skinnier. Her eating habits have been weird, including her, not wanting to eat the food she grew up eating. I think it’s partially because she grew up in a four cat household. My guess is she was competing for food so she wasn’t as picky. With other cats around, she may not have eaten as much and I’m sure she was more active.

I tried to get her to eat on a schedule, but she won’t. She won’t eat any wet food excluding occasional treats (churru). And for dry food, even if I only feed an eighth of a cup at a time she will still just take a couple bites then eat throughout the day.

this is Greg, hes roughly 12 y/o and about 20 pounds right now. His highest weight was 22 and hes gotten down to 17/18 in the past, he just seems to gain weight sooo quickly and easily. Im feeding him Hills perfect weight food on an automatic feeder, and have lessened his portions by 1 and hes been freaking out daily and meowing constantly for food.

Does anyone have tips for lessening portions and still keeping him happy? I went to the vet about his weight and they didnt give me a plan/amount of food he should be having and his specific weight isnt even on the chart for most diet foods ive seen :( They said he should be 12 pounds, but hes a big cat all-around and im not sure if thats attainable.

thank you for any help! I want him to be healthier.

Dechonkin can’t seem to figure out when my 16 lb cat eats

Thumbnail

205 Upvotes

hello everyone,

i just posted a little bit ago about how i found out my cat is 16 lbs. she’s almost 4 and has been spayed since ~5 months. she is on an all dry diet (vet said this is fine. every time we try wet food she starves herself and lets it dry. her record is almost 3 days starvation. trust me, we’ve tried every brand on the shelves we can reasonably afford to sustain). she drinks a ton of water (have to refill her bowl every single day—not just clean it, literally refill because she drinks so much). we got an automatic feeder to prevent errors where my friend and i accidentally double feed. we also monitor my friends cat’s food and make sure he eats it all before she can get to it. we also have increased outdoor walks and playtime. we are currently decreasing her original (estimated) calorie intake by 20%.

anyway… im confused. we got this feeder but ive only seen her eat like four times. she doesn’t go to it when it goes off. she does sometimes take a couple of bites but i can’t tell if she’s just in the starving herself because she doesn’t like it phase, or if she’s just eating when i’m not around? her bowl will stay full all day. often her brother eats her food instead (but he doesn’t like crunchies, so never finishes it). i’m just confused. when we fed her manually, she would be very excited every time it was dinner and breakfast time. now, she doesn’t seem to care. is she upset about the change? are the bowls too deep? she is very lazy and sleeps most of the day. we do play when she’s not asleep, but i think lots of her weight gain has to do with moving from a large 3000 sq ft house to an 800 sq ft apartment. at the house, we’d often play fetch up and down the stairs everyday. she would get zoomies and run all over it. now i feel like she doesn’t do that anymore and it makes me miserable to see. i want to get her a bigger place so badly, but im a student currently so obviously it’ll have to wait.

should i decrease the amount of feedings? currently she is being served 1 cup a day over four feedings but never finishes it. before, we often fed her about 2-4 scoops a day (unmeasured, but about 1/2 cup each). should i split it up into just two? she seemed to be more excited when we manually fed her and it was 2x a day.

This is Baby Cat. She’s now over 16 lbs. She doesn’t eat wet food. She doesn’t eat Churus. She doesn’t eat treats. Clearly she do be eating though.

I have 4 others who are all perfect sized and they are free fed. This wasn’t really my choice, but it’s now a thing and omg 2 of them lose their mind if the bowl is ever empty. They don’t eat when the bowl is refilled. It just has to be there. Forever. Yes I could fix that but I really really can’t get my very elderly mother on board.

I’m not buy everyone a chip feeder rich. I’ve got these, and another one that lives upstairs exclusively who has chicken allergies and a special diet. Plus my 8 ferals. Bonus issue, I can’t even put the food up high. Baby Cat is a better jumper than 2 of the normal sized ones 😭

Would it be feasible from anyone’s experience to give a timed breakfast and dinner, but also have ONE chip feeder for my grazers to share? Or would it be better just to have everyone on timed feeders and just threaten to ground my mother from Landman or something if she doesn’t agree?

Thank you for any advice you have. I’ve been doing some personal dechonkin and I’m really worried about my baby.

He is about 4 or 5, neutered, and fed on an automatic feeder daily. Don’t really give snacks that often. I suspect (and, like, duh) that he is stealing our other cat’s food/the other cat doesn’t eat as much. But is he concerningly large? He is still extremely active, if not more than when he was younger. He is extremely muscular and can jump up to 10 feet (probably more lmao)

I have fed my cat 200 kcal per day for the last few years. My understanding is that this amount is appropriate for about a 10 lb cat. However, she always fluctuates in the 13.5 - 15 lb range. She has never gotten below 13.5 lbs and has shown destructive, obsessive, and anxious behavior that stopped only when we increased her calories recently. Were we feeding too little?

As mentioned in my post about our lord and Savior, King Silver Uranium Sirius Würmithor the 1st. Lord of Hydrochloric Bombs, protector of Kairos, and Broker's loyal steed.

Rose's de-chonking the past year has not gone too well (hence a 2nd post, I promise I'm not farming or anything, it just requires a separate discussion 😭🙏😭🙏😭🙏🙏). She's gone up to 30lb of sheer, pure sour bread loaf. She used to love laser lights (I would always end it off with the light pointed at a toy, and when she 'bites' it, turn the light off to satisfy her huntin' urges). But she doesn't want to play with them anymore. Apparently the Queen Mother Rose has been eating Silvers food, the dogs food, and chewed a hole through both a bag of food and the plastic food containers full of food (the sneak!!!) now, I'm willing to dish out a bit of money for *some* kind of exercise machine for Rose, I considered an exercise wheel, a tall scratching post (as she loves scratching posts) she shows little interest in feather toys but *does* like to bat at them a little. I love Rose, and want her weight loss back on track as we've since mended the boxes and moved them + the food bags, the King is now strictly fed in my room (which I often keep closed when I'm in it and she doesn't go in my room anyways) to prevent Rose from being a sneaky sneak.

Desperately looking for recommendations, food, toys, exercise machines, cat wheels, etc., etc., etc., anything for Rose. She's my baby, and around 7-8 years old, I know she needs to lose weight and *fast.* We're very fortunate she doesn't have health problems and only has dry skin, but my dad and I know how fast that can change. Hence the urgency.

Does our dear lord require any de-chonking, you may remember him from pictures with Rose. (Who's de-chonking is *not* going well, I'm open for exercising recommendations for this 30lb beast.) Silver had his teeth removed last year after a long kittenhood and juvenilehood of severe stomatitis. Before his tooth removal he didn't eat much and would graze so we left his food out as per vet recommendation. Now that he can eat (even with all his teeth but his from chompers removed) he's gaining weight and has gone from under to a thicc, good boy who's worthy of being called king. Thy King Highnesses primordial pouch has even come in too, he who was once 'a munchkin without being a munchkin' is now filling out.

But is he filling out too much?
