Psychological benefits of a high-protein, low-carbohydrate diet in obese women with polycystic ovary syndrome—A pilot study (2011)
Abstract
This study compared the psychological effects of a low-protein high-carbohydrate (LPHC) diet and a high-protein low-carbohydrate (HPLC) diet in women with polycystic ovary syndrome (PCOS). Twenty-five overweight women with PCOS were matched for age, weight, and whether they were trying to conceive. They were randomly allocated to the LPHC or HPLC diet for 16 weeks. All participants attended a weekly exercise, group support and educational program. The Hospital Anxiety and Depression Scale and the Rosenberg Self Esteem Scale were administered at the beginning and end of the study. The HPLC diet was associated with significant reduction in depression and improvement in self-esteem. There was no change in any psychological measures for the LPHC group. There was no difference in weight loss between the groups. Due to enhanced feelings of well-being, it is possible that HPLC diets may be associated with better compliance and hence be more successful in the long term treatment of obesity.
Fast-food and commercial baked goods consumption and the risk of depression (2007)
Abstract
Objective Whereas the relationship between some components of diet, such as n-3 fatty acids and B-vitamins, and depression risk has been extensively studied, the role of fast-food or processed pastries consumption has received little attention.
Design Consumption of fast food (hamburgers, sausages, pizza) and processed pastries (muffins, doughnuts, croissants) was assessed at baseline through a validated semi-quantitative FFQ. Participants were classified as incident cases of depression if they reported a physician diagnosis of depression or the use of antidepressant medication in at least one of the follow-up questionnaires. Cox regression models were fit to assess the relationship between consumption of fast food and commercial baked goods and the incidence of depression.
Setting The SUN (Seguimiento Universidad de Navarra – University of Navarra Follow-up) Project, Spain.
Subjects Participants (n 8964) from a Spanish cohort.
Results After a median follow-up of 6·2 years, 493 cases of depression were reported. A higher risk of depression was associated with consumption of fast food (fifth (Q5) v. first quintile (Q1): hazard ratio (HR) = 1·36; 95 % CI 1·02, 1·81; P trend = 0·003). The results did not change after adjustment for the consumption of other food items. No linear relationship was found between the consumption of commercial baked goods and depression. Participants belonging to consumption quintiles Q2–Q5 showed an increased risk of depression compared with those belonging to the lowest level of consumption (Q1; HR = 1·38; 95 % CI 1·06, 1·80).
Conclusions Fast-food and commercial baked goods consumption may have a detrimental effect on depression risk.
Unbeliever said:Don't you think xyzzy that there is always some confusion beween low carbing for weight loss and low carbing for reduction of blood glucose?
If we try to seperate the two issues would we get totally different results? I am not disagreeing with anything you or anyone else has posted and I know that the majority of diabetics are overweight on diagnosis but I am constantly sruck by the fact that so many studies could just as easily refer soley to overweight and obesity issues and not diabetes.

Totally! People often comment on the fact that I manage on about 150 to 180 grams of carbs a day. Fact is, this gives me an HbA1c of 5.9, although I suspect probably a fair bit lower now (might find out soon) I could get a lower HbA1c by dropping the carbs more, and would be happy to, BUT my weight problem is the opposite to most peoples here. With a BMI of 22, I'm a tad on the light side and struggle to keep my weight up. My weight undoubtedly drops rapidly with carb reduction (lost nearly 2 stone quickly on diagnosis and carb reduction) so I keep my carbs up as high as is reasonable commensurate with maintaining a good HbA1c. If I was overweight, I'd drop my carb intake a lot more. With me, it's about juggling carbs, BG and kilos.
viviennem said:As for depression on diagnosis - well, if being told by a "specialist" that Type 2 is progressive, and that nothing will stop that progression to insulin, blindness and amputation, if CHD or a stroke don't get you first, doesn't lead to depression, I don't know what will!
It just made me angry, which is a great motivator.

Yes me too. I still get it from one paranoid member.

Reminds you of "The Prisoner" doesn't it. "I am not a low-carb fanatic, I am a free man!" (or woman in Viv's case) :lol:

I however, am a low carb fanatic!
Also I quite like the idea of being an undercover member of the trouble-making fraternity; sounds like the Masons gone bad...
I agree that the angels on pins argument is as redundant as it is boring, but I kind of also feel it is a fake argument. Surely, no one with half a brain was saying people must be at such and such a level to be considered a low carber?
I'd like to be able to eat more carbs (who wouldn't?!) but alas have to keep my intake to around 30 grams a day (an Atkins induction type level).
That doesn't mean anyone else has to, but nor does it mean that my response to people with problems with their diabetes control shouldn't be; 'cut the carbs'.
Do you see what I mean? Or am I getting lost in the semantics of it...
Anyway we should all consider this when becoming enraged with doctrinal disputes;

Low- and high-carbohydrate weight-loss diets have similar effects on mood but not cognitive performance (2007)

Background: Low-carbohydrate diets are often used to promote weight loss, but their effects on psychological function are largely unknown.
Objective: We compared the effects of a low-carbohydrate, high-fat (LCHF) diet with a conventional high-carbohydrate, low-fat (HCLF) diet on mood and cognitive function.
Design: Ninety-three overweight or obese participants [ ± SEM age: 50.2 ± 0.8 y; body mass index (in kg/m2): 33.6 ± 0.4] were randomly assigned to an energy-restricted (≈6–7 MJ, 30% deficit), planned isocaloric LCHF diet or an HCLF diet for 8 wk. Body weight and psychological well-being were measured by using the Profile of Mood States, Beck Depression Inventory, and Spielberger State Anxiety Inventory instruments at baseline and fortnightly. Cognitive functioning (working memory and speed of processing) was assessed at baseline and week 8.
Results: The LCHF diet resulted in significantly greater weight loss than did the HCLF diet (7.8 ± 0.4 and 6.4 ± 0.4 kg, respectively; P = 0.04). Both groups showed improvements in psychological well-being (P < 0.01 for time), with the greatest effect occurring during the first 2 wk, but there was no significant difference between groups. There were no significant between-group differences in working memory (P = 0.68), but there was a significant time x diet interaction for speed of processing (P = 0.04), so that this measure improved less in the LCHF than in the HCLF diet group.
Conclusions: Both dietary patterns significantly reduced body weight and were associated with improvements in mood. There was some evidence for a smaller improvement in cognitive functioning with the LCHF diet with respect to speed of processing, but further studies are required to determine the replicability of this finding.
