Someone please explain to me why it's always calories in vs calories out, Law of thermodynamics etc.. What about ppl saying "muh slow metabolism" how do I shut these people up? Any studies etc? How important are macros for fat loss?
If you eat more calories then you burn off you gain weight it's that fucking simple
>fat is a storage device
>when you have shit to store your body stores it
>when you need more than you have you take it out of storage
those people are typically lying about their diets, oh I don't eat a lot but gain weight, let's forget about the 10 snacks I had throughout the day though those don't count as meals.
Macros are important for fat loss, typically high protein to build muscle/prevent muscle loss/gain or maintain strength, Carbs are important for energy however an excessive amount will make fat loss more difficult, and Fat is an important fuel source as well as for your bodies hormones and essential needs.
For fat loss I recommend a high protein, moderate/low carb and low/moderate fat diet. More carbs on days you're doing cardio and having intense lifts, more fat and lower carbs on days you're resting or not as demanding on your body.
slow metabolism simply means you have to eat less.

They are either overestimating how much they expend or are underestimating how much they eat. Often the latter, but it IS one or the other.

>RESULTS:
>Total energy expenditure and resting metabolic rate in the subjects with diet resistance (group 1) were within 5 percent of the predicted values for body composition, and there was no significant difference between groups 1 and 2 in the thermic effects of food and exercise. Low energy expenditure was thus excluded as a mechanism of self-reported diet resistance. In contrast, the subjects in group 1 underreported their actual food intake by an average (+/- SD) of 47 +/- 16 percent and overreported their physical activity by 51 +/- 75 percent. Although the subjects in group 1 had no distinct psychopathologic characteristics, they perceived a genetic cause for their obesity, used thyroid medication at a high frequency, and described their eating behavior as relatively normal (all P < 0.05 as compared with group 2).
>CONCLUSIONS:
>The failure of some obese subjects to lose weight while eating a diet they report as low in calories is due to an energy intake substantially higher than reported and an overestimation of physical activity, not to an abnormality in thermogenesis.
