Intermittent fasting (IF) diets are worse for your blood sugar and blood pressure, new meta-analysis finds.
In yesterday's post I discussed a large-scale study showing that IF diets are no better for fat loss than other diets, given the same macronutrient intakes. Many people are aware of this now, but many people still practice IF diets for their proposed health benefits.
A new meta-analysis of randomized controlled trials finds that intermittent energy restriction diets are actually not healthier than diets with constant energy restriction.
In fact, the IF diets were worse for some outcomes. Systolic blood pressure and blood glucose levels decreased further in the constant energy restriction group.
I wouldn't put too much stock into those seemingly negative effects though, as overall, health and body composition outcomes improved similarly in both groups.
These results are in line with another new meta-analysis of experiments (RCTs) on time-restricted eating.The researchers found no significant differences between time-restricted eating diets and control diets in waist circumference, BMI, blood sugar levels (A1C) or blood pressure
All in all, the evidence is now quite conclusive that you don't need to practice intermittent fasting for optimal health. If you like it, it's a fine way to restrict your energy intake, but you can be just as healthy on 4 meals a day with an early breakfast.
New study says:
red meat not unhealthy &
high protein diet not uniquely satiating
A new 3-month study with over a 100 participants compared eating 25 vs. 125 g of unprocessed beef daily. The researchers reported 2 interesting findings.
First, "changes in cardiometabolic risk factors were not different between groups", indicating the extra beef has no measurable adverse health effects.
Red meat consumption does not cause cardiovascular disease,
new systematic review says
Red meat consumption is correlated with cardiovascular disease in many studies. However, people that eat more red meat on average also have a significantly worse lifestyle than people that eat less red meat.
They smoke more, they consume more sugar and they're less wealthy. So is red meat or one of these other factors the culprit? Covariate analyses are always limited by knowing the covariate and having it in your data set, among other limitations.
Many people are under the impression that keto diets are better for fat loss but worse for muscle growth than higher-carb diets.
Last week I posted a review on the ketogenic diet for concurrent athletes that concluded keto diets are actually equally effective for both fat loss and muscle growth.
Now a new meta-analysis specifically on strength trainees, both male and female, concluded that keto diets are indeed equally effective to gain muscle.
A new meta-analysis of the scientific literature sought to answer this question by looking at velocity stops.
During a set, your velocity gradually decreases until it reaches 0 in the biomechanical sticking point when you reach momentary muscle failure. The level of velocity loss can thus serve as an objective measure of how close to failure you are.
However, one problem with the use of velocity-based training is that the relationship between proximity to failure and velocity loss is highly individual and context-dependent. It differs per exercise, training intensity and individual.
New meta-analysis says 1.5 g/kg protein is enough to maximize strength development
One of my first articles was about the myth of 1 gram protein per pound of bodyweight. I argued 0.82 g/lb was more than enough to optimize our gains based on the research, in contrast to virtually every other source in fitness at the time.
This article stood the test of time extremely well. In 2017, I participated in a meta-analysis of the literature that found 1.6 g/kg/d was the break-off point of further benefits in gains.
