    Science aside...I have to look at slow weightloss from a more practical point of view... I'm at 'normal' weight, whatever the range for my size. I can still dump 10 lbs in a month with an insane calorie deficit, but then what? The muscles will still be there, but I'll be miserably hungry. For me, slow weightloss eases the transition to staying at an overall lower calorie intake.
    Right now, I'm eating at maintenance, lifting heavy weights, and dropped 7 lbs since Christmas, not even trying. If I keep that up, I'll be just the right shape, come bikini season...and the hinges on my fridge will still be intact...

    Pretty much every reputable medical website (CDC, NHS in the UK, Mayo Clinic, etc) says it's safe to lose 1 to 2 lbs a week.

    Same in Australia - recommendation for healthy adults is 0.5-1kg a week, which is 1.1-2.2lbs.

    Of course in practice will have ups and downs, and it can be hard to lose this much consistently every week so people shouldn't feel bad if they are losing less. But there is no health reason I can see why (when the health departments of educated nations recommend this) it would be a problem to lose this much as long as you are eating clean and healthy to meet nutritional needs as well.

    it is safe to lose 1-2 lbs a week IF you have plenty to lose. they fail to tell you that.trying to lose 1-2 lbs a week when you have say less than 20 lbs to lose is asking for issues.the less fat stores you have to help with the weight loss the more lean mass you are going to lose being too aggressive with weight loss. if you have more than 50 lbs to lose then yes 2 lbs /week will be safe for a short time. ask those who go on very low calorie diets to lose the weight quickly when they dont have a lot to lose what can happen over time. your body only burns so much fat at a time as it is.

    There is no evidence that there is a limit to fat loss. Even Lyle McDonald's original estimates haven't been demonstrated in studies. And yes, while in general, cutting quickly is going to cause increased muscle loss, that isn't always true. Its going to depend on your training and protein levels.

    Where people fail is excessively cutting calories while not exercising and not eating adequate protein.

    no there isnt a limit to fat loss but your body only burns so much a day how much Im sure will vary person to person. but when you dont have the fat stores to lose its not going to come off fast even if you are cutting calories really low. which is why I said being too aggressive with weight loss.and even with enough protein and traninging if a person is eating too little calories I dont think that the protein and training is going to be enough cause the caloires are too little correct? or no?

    I'd recommend reading some of Lyle's protocols, especially PSMF. Even with low body fat, you can lose quite a bit of fat without muscle loss. The bigger issues you tend to face with aggressive fat loss, is ability to comply/adhere to the diet, the willingness to eat primarily lean protein only, recovery from training, some lethargy and probably binging depending on your personality.

    Where is becomes an issue is when people aggressively diet without refeeds. The leaner you are, the more refeeds are required.

    And of you really want to understand the particulars of those diets, go over to the bodybuilding section. Especially the below thread.

    @psuLemon you do recall that given exposure to media expectations and a quick results culture more people using weight loss diets (or even MFP) end up in big loss-big regain cycles (or worse end up in restrict/binge cycles) than end up in sustainable bodybuilding and carefully considered cuts and bulks coordinated with appropriate exercise.

    I send your way words close to things you've said to me in the past :)

    This is the general section with general discussions and recommendations suitable for the majority of MFP users. The bodybuilding section addresses different requirements and may cater to people with slightly different needs. Are most MFP users bodybuilders?

    Keep in mind, that I am not arguing that one should aggressively cut. I already mentioned the issues with aggressively losing weight. Extreme dieting protocols have their place, but in generally, it's with the morbidly obese while under care of a physician and those who are very knowledgeable on how to properly quickly. And yes, I always suggest finding the most appropriate path that aligns to ones goals and is most likely to adhere. For me, that would never be 1/2 lb per week. It doesn't lend itself to much error.

    But semantically, there is NO evidence currently, at least that I am aware of, that one can only oxidize so much fat in a given date. Even reading Lyle's old article seems like it was more theoretical (similar to his perfect lean bulk information). And given that the majority of people here like to argue semantics, I thought I would point that out.

    I looked up Kelsey, the woman in those photographs - she is still on IG, albeit on a different account now. In one of her posts she admits that upon reaching her original goal weight, the MIDDLE PHOTO, she was BELOW the healthy weight range for her size. Just an fyi.

    And, she has now gained even more muscle and is at her original weight. I think she looks fabulous.
